Description

Granular wooden biomass fuel ordering system

Technical Field

The invention relates to a granular wooden biomass fuel ordering system.

Background

Due to the implementation of the japanese renewable energy special measure act, etc., the development of technologies for using woody biomass such as trunks and branches of trees, chips, sawdust, bark, construction waste, etc., which are renewable energy, as an alternative fuel for power generation boilers or cement clinker firing facilities has been advanced.

For example, in the case of using cut wood as fuel for a power generation boiler, the demand amount of cut wood reaches several tens of thousands of tons or more per year. However, in order to stably and efficiently supply woody biomass as a fuel, there are many problems such as seasonal variation in supply amount due to tree growth and mass transportation between a supply site and a demand site.

Further, the fuel is required to have stability of quality such as calorific value (calorific value), and thus, in order to secure a supply amount required throughout the year, it is necessary to use a plurality of supply places or a plurality of types of woody biomass in combination in consideration of seasonal variations and the like in relation to the supply amounts of the various woody biomass fuels. When a plurality of woody biomass fuels are used in combination or in a mixed manner, a technique for stabilizing the quality to prevent the quality characteristics of the woody biomass fuel as a final product from being varied is required.

For example, patent document 1 below discloses a system and a method for collecting and selling a coal-woody biomass mixed fuel in which woody biomass (cut wood, bagasse, oil palm, rice hull, etc.) and coal are mixed, and a fuel collection and sale company sells a coal-woody biomass mixed fuel in which woody biomass and coal are blended according to conditions (the type of woody biomass, the mixing ratio of coal and woody biomass, the combustion calories, etc.) required by a fuel user.

Disclosure of Invention

Problems to be solved by the invention

However, the system and method for collecting and selling a coal-based and woody biomass mixed fuel disclosed in patent document 1 only reside in the technology related to information processing for matching purchase request information on the side of a customer and inventory information on the side of a supplier, and are not fundamental solutions related to supply stabilization and quality stabilization.

The consumers utilizing woody biomass fuels have historically placed orders directly from suppliers of woody biomass fuels that include the quality and quantity of woody biomass fuel required by the consumers themselves. In this case, when a certain supplier a does not have a sufficient stock of woody biomass fuel satisfying the quality required by the customer, the customer needs to place the same order for the other supplier B. As described above, depending on the stock status of the supplier, the customer needs to order a plurality of suppliers and the workload of the purchase responsible person increases.

In addition, if a customer desires to order a woody biomass fuel of higher quality than before, there is a case where it is necessary to find a new supplier to order, which is different from the supplier who has already performed the transaction. However, since it is often difficult for the demander to rely on the quality information on the woody biomass fuel supplied by the supplier without the trade performance record, it is actually necessary to perform a quality check on the demander side. Therefore, even if a new supplier can be found, the delivered fuel cannot be used immediately, and the convenience of fuel use becomes worse for the demander. In addition, when a supplier capable of providing high-quality fuel is initially searched again, there may be a case where a large workload is imposed on a purchase obligator.

The present invention has been made in view of the above-described problems in the logistics of woody biomass fuels, and an object of the present invention is to provide a ordering system capable of stably supplying granular woody biomass fuels of a quality required by consumers to consumers without placing a heavy burden on the consumers.

Means for solving the problems

The present invention relates to a granular woody biomass fuel ordering system (i.e., an ordering reservation-acceptance system) in which,

the ordering system has:

a management server for monitoring the stock state of a fuel management base composed of a product placement site, an acceptance material placement site, and a processing equipment, wherein

The product placing place stores product fuels as granular woody biomass fuels in a shippable state by quality classification,

the acceptance material placing place stores acceptance material fuel for processing to generate the product fuel in a quality classification,

said processing equipment subjecting said acceptance material fuel to said processing to produce said article fuel;

a customer terminal configured to be capable of communicating with the management server and to receive input of first order information on a customer side, the first order information including information on a required quality and a required amount of the product fuel; and

an in-base terminal configured to be capable of communicating with the management server and configured to instruct, in the fuel management base, a job related to a shipping process and/or the processing process;

and is

The management server comprises a storage unit, an inventory determination unit, a shipment processing instruction creation unit, and an inventory update unit

The storage section stores first stock quantity information relating to a stock quantity by quality of the product fuel stored in the product placing location and second stock quantity information relating to a stock quantity by quality of the acceptable material fuel stored in the acceptable material placing location;

the stock determination unit reads the first stock quantity information and the second stock quantity information from the storage unit when the first order information is transmitted from the customer terminal, and determines whether or not delivery of the product fuel satisfying the required quality and the required amount described in the first order information can be performed by calculating, based on the product fuel currently stored in the product placement location and the product fuel generated by subjecting the acceptance material fuel stored in the acceptance material placement location to the processing by the processing facility;

a shipping instruction creation unit that, when the shipment can be performed, transmits shipping instruction information to the terminal in the base, the shipping instruction information including first consumption information and/or second consumption information, the first consumption information being a quality-classified amount of the product fuel necessary for the shipment, the second consumption information being a quality-classified amount of the acceptance material fuel necessary for the processing for the shipment;

the inventory update unit updates the first stock quantity information and/or the second stock quantity information stored in the storage unit based on the first consumption amount information and/or the second consumption amount information.

The ordering system for granular woody biomass fuel (hereinafter sometimes abbreviated as "ordering system") of the present invention includes a management server, a requester terminal, and an in-base terminal. The management server has a function of monitoring the stock condition of the fuel management base. The customer terminal is a terminal capable of inputting information (first order information) relating to the quality and quantity of the demanded fuel from the customer side to the management server. The terminal in the base is a terminal capable of transmitting a shipping instruction and/or a processing instruction in the fuel management base from the management server, and is, for example, a terminal that an operator of the fuel management base can confirm as appropriate.

The management server is configured by, for example, a general-purpose computer having an arithmetic processing function and a storage function. The demander terminal and the in-base terminal are configured by, for example, a portable terminal such as a smartphone in addition to a general-purpose computer. The management server may be present in the site of the fuel management base or may be present in a site remote from the site of the fuel management base.

The fuel management base has a function of storing fuel supplied (transported) from one or more suppliers (fuel manufacturing sites) as fuel supplied (transported) from the suppliers, and the following is conceivable: the fuel is a fuel obtained by granulating a fuel having a quality (hereinafter referred to as "shippable quality") that enables direct shipment to a customer; this fuel is a fuel that has not reached a shippable quality because it has not been pelletized, and thus cannot be shipped directly and requires processing. This difference is due to the manufacturing and processing capabilities of the suppliers, etc. In the present specification, the former fuel is referred to as "product fuel", and the latter fuel is referred to as "acceptance material fuel".

The fuel management base includes: a product placement location for storing product fuel by quality classification; and a place for placing the acceptance material for storing the acceptance material fuel by quality classification. The management server includes a storage unit in which: information (first stock quantity information) relating to the stock quantity by quality of the product fuel stored in the product placement site; and information (second stock quantity information) relating to the stock quantity by quality of the acceptance material fuel stored in the acceptance material placing place. That is, the management server is configured to be able to identify, by quality, the fuel inventory amount that satisfies the invokable quality and the fuel inventory amount that does not satisfy the shippable quality, which are stored in the current fuel management base, respectively.

The fuel management base has a process facility for performing a process on the approved material fuel to produce a manufactured fuel. That is, as described above, even when the fuel transported from the supplier is of a quality that cannot be directly shipped without being pelletized, it can be converted into a fuel (product fuel) having a shippable quality in the fuel management base.

The management server has an inventory determination unit. The stock determination unit is an arithmetic processing unit that performs predetermined arithmetic processing based on the acquired information, and is configured by dedicated software and/or hardware. When the first order information is transmitted from the customer terminal, the stock determination section determines whether or not delivery of product fuel satisfying the quality (required quality) and quantity (required amount) described in the first order information can be performed based on the stock amount currently stored in the fuel management base. Here, as described above, the storage unit of the management server stores the information (first stock quantity information) on the stock quantity by quality of the product fuel, and also stores the information (second stock quantity information) on the stock quantity by quality of the certified material fuel. Therefore, for example, when the stock quantity of the product fuel stored in the fuel management base to satisfy the demanded quality of the demanded customer is insufficient with respect to the demanded quantity of the demanded customer, there is a case where the demanded quantity of the demanded customer can be satisfied by processing the acceptance check material fuel in the processing facility included in the fuel management base to generate the product fuel satisfying the demanded quality.

In consideration of the above point, the inventory determination unit reads the first inventory information and the second inventory information from the storage unit, and determines whether or not the delivery of the product fuel satisfying the demanded quality and the demanded amount of the customer from the fuel management base can be performed at present by calculation.

The management server has a shipping processing instruction creation unit. The shipping instruction creation unit is an arithmetic processing unit that performs predetermined arithmetic processing based on the acquired information, and is configured by dedicated software and/or hardware. The shipping processing instruction making unit has the following functions: when the stock judging unit judges that the delivery of the product fuel satisfying the quality and the quantity required by the customer from the fuel management base is currently possible, the required quantity of the fuel is transmitted to the base terminal together with the information of the quality.

As an example, a case may be considered where the product fuel stored according to the current fuel management base can be concerned with satisfying the demand of the demander. In this case, the shipping instruction creation unit transmits only information (first consumption amount information) on the quality and amount of the required product fuel to the base terminal. At this time, on the fuel management base side, when the first consumption amount information is received in the in-base terminal, necessary operations can be performed to deliver product fuel that satisfies the quality and amount based on the information to the customer.

As another example, a case may be considered where the product fuel stored in the current fuel management base cannot be made to meet the needs of the demander but can meet the needs of the demander by processing the acceptance material fuel stored in the fuel management base. In this case, the delivery/processing instruction creation unit transmits information (second consumption amount information) relating to the quality and amount of the acceptable material fuel required for the processing, together with the first consumption amount information, to the base terminal as necessary. At this time, on the fuel management base side, when the second consumption amount information is received in the in-base terminal, necessary operations can be performed to process the accepted material fuel satisfying the quality and amount based on the information by the processing equipment.

The management server has an inventory update unit. The stock update unit is an arithmetic processing unit that performs predetermined arithmetic processing based on the acquired information, and is configured by dedicated software and/or hardware. The stock update unit has the following functions: when the shipping instruction creation unit transmits the first consumption amount information and/or the second consumption amount information to the fuel management base, the shipping instruction creation unit updates the first stock amount information and/or the second stock amount information stored in the storage unit based on the first consumption amount information and/or the second consumption amount information. As a result, information on the stock quantity stored in the current fuel management base is stored in the storage unit of the management server.

That is, according to the present system, the customer can order the product fuel satisfying the required quality and the required amount without individually transmitting the order information to each supplier, and the product fuel satisfying the required quality and the required amount can be stably secured. In particular, by storing the product fuel and the acceptance material fuel in the logistics management base, it is possible to buffer seasonal variation associated with the supply amount of the woody biomass fuel, supply amount variation caused by logistics problems and the like by the storage capacity of the logistics management base, and to enable the consumers to obtain stable supply.

In addition, even when the stock of product fuel satisfying the required quality in the fuel management base is insufficient, the demand of the demander can be satisfied by appropriately performing necessary processing.

The management server includes a processing result calculation unit that calculates, based on the amount of the acceptable material fuel classified by quality used for the processing, the quality and amount of the product fuel generated by the processing;

the inventory determination unit may determine, based on the calculation result of the processing result calculation unit, whether or not the shipment of the product fuel satisfying the required quality and the required amount described in the first order information can be performed by calculation.

The machining result calculation unit is an arithmetic processing unit that performs predetermined arithmetic processing based on the acquired information, and is configured by dedicated software and/or hardware. Based on the above configuration, when the product fuel stored in the current fuel management base cannot meet the demand of the demander, the management server can calculate by calculation: about what quantity of accepted material fuel to process is to produce about what quantity of product fuel to meet the required quality.

For example, the processing result calculation unit can determine the quality of the product fuel produced by applying the processing treatment, based on the ratio of the quality-classified amounts of the acceptable material fuels used in the processing treatment.

The management server includes a product mixture result calculation unit that calculates, based on the amounts of the product fuels classified by quality, the quality and amount of the product fuel generated by mixing the product fuels of different qualities by calculation;

the inventory determination unit may determine, based on the calculation result of the product mixture result calculation unit, whether or not the shipment of the product fuel satisfying the required quality and the required amount described in the first order information can be performed by calculation.

The product mixture result calculation unit is an arithmetic processing unit that performs predetermined arithmetic processing based on the acquired information, and is configured by dedicated software and/or hardware. For example, in the case of a product fuel having a quality closest to the demanded quality of the customer, it is considered that a sufficient amount of product fuel having a quality higher than the demanded quality and a sufficient amount of product fuel having a quality lower than the demanded quality are stored in the product storage location, although the product fuel is not sufficiently stored in the product storage location. In this case, the required quality and the required amount may be satisfied by mixing the high-quality product fuel with the low-quality product fuel. The product mixture result calculation unit can determine what quality of product fuel is generated by mixing approximately how many product fuels of different qualities. The stock determination unit determines whether or not delivery of the item fuel satisfying the ordered content is possible based on the calculation result of the item mix result calculation unit, thereby further increasing the possibility that the item fuel satisfying the ordered content can be delivered to the customer.

The ordering system has a supplier terminal configured to be capable of communicating with the management server,

the first order information contains information relating to a required delivery date;

the management server may be configured to have a supplier extraction unit, a shortage calculation unit, and a reservation ordering unit for a supplier

A supplier extracting unit that extracts, when the stock determining unit determines that the shipment cannot be performed, one or more suppliers that can supply the acceptance material fuel or the product fuel to the fuel management base during a delivery date that satisfies the required delivery date described in the first order information by calculation;

the shortage calculation unit calculates, by calculation, a first shortage, which is an amount of the product fuel classified by quality necessary for addition to satisfy the required quality and the required amount described in the first order information, and/or a second shortage, which is an amount of the acceptable material fuel classified by quality necessary for addition to satisfy the required quality and the required amount described in the first order information, and which is classified by quality;

the supplier reservation ordering unit creates second ordering information including the first shortage and/or the second shortage, and the supply delivery date, and transmits the second ordering information to the supplier terminal managed by the supplier extracted by the supplier extracting unit.

The ordering system configured as described above has a supplier terminal. The supplier terminal is a terminal managed by a supplier (fuel manufacturing site), and is configured by a portable terminal such as a smartphone in addition to a general-purpose computer. The supplier extraction unit, the shortage calculation unit, and the supplier reservation ordering unit of the management server are all arithmetic processing units that perform predetermined arithmetic processing based on the acquired information, and are configured by dedicated software and/or hardware.

Even if the inventory determination unit has the inventory of the product fuel and the acceptance material fuel stored in the fuel management base, it may be determined that the shipment corresponding to the order satisfying the required quality and the required amount specified by the demander cannot be performed.

In this case, based on the above-described configuration, first, the supplier (fuel manufacturing site) capable of supplying fuel to the fuel management base during a period satisfying the required delivery date specified by the demander (i.e., during the delivery date that is a period shorter than the required delivery date) is extracted in the supplier extraction portion. Next, the shortage calculation unit calculates the amount (shortage) of the product fuel and/or the acceptable material fuel, which is required to be added to satisfy the required quality and the required amount specified by the customer, classified by quality. The supplier reservation ordering unit transmits, to the supplier extracted by the supplier extraction unit, order information (second order information) for an amount corresponding to the shortage amount classified by quality to be supplied to the fuel management base during the supply delivery period.

That is, based on the above configuration, even when the product fuel and the acceptance material fuel stored in the ignition material management base at the time of order initiation by the customer cannot satisfy the demand of the customer in terms of stock quantity, the supplier capable of additionally supplying the fuel to the fuel management base is automatically selected and the reservation ordering process is performed. Thereby further increasing the likelihood that the customer will be able to ship product fuels that meet the ordered content.

The storage part stores processing time information and transportation time information, wherein,

the processing time information is related to a processing time necessary in the processing equipment for generating the article fuel for the acceptance material fuel to be subjected to the processing,

said transportation time information is related to the transportation time necessary for each of said suppliers to transport said acceptance material fuel or said article fuel from said supplier's site to said fuel management base;

and is

The supplier extraction unit may be configured to: one or more suppliers are extracted based on the information on the required delivery date described in the first order information, and the processing time information and the transportation time information stored in the storage unit.

With the above arrangement, the supplier extracting unit can extract not only the supplier who can supply the product fuel satisfying the required quality during the delivery date of supply, but also the supplier who can supply the acceptance material fuel capable of generating the product fuel satisfying the required quality during the delivery date of supply, in consideration of the time for performing the processing in the processing facility in the fuel management base. Thus, even when the product fuel and the acceptance material fuel stored in the management base are ignited at the time of order initiation by the customer and cannot meet the demand of the customer in terms of stock quantity, the possibility of being able to deliver the product fuel satisfying the order to the customer is further increased.

The storage unit stores manufacturing capability information relating to the quality of the acceptance material fuel or the product fuel that can be manufactured by each of the suppliers;

the supplier extraction unit may be configured to:

extracting, from the plurality of suppliers, supply candidates capable of manufacturing the production fuel of a quality necessary for addition to satisfy the required quality and the required amount described in the first order information and/or the acceptance material fuel of a quality necessary for addition to satisfy the required quality and the required amount described in the first order information and the processing performed based on the manufacturing capability information by calculation; on the basis of the above-mentioned technical scheme,

performing a process of extracting by operation one or more of the suppliers of the supply candidates who can supply the acceptance material fuel or the production fuel to the fuel management base within the supply delivery period.

Among suppliers (fuel production sites) who supply product fuels and/or acceptance material fuels to a fuel management base, there are cases where there is a possibility that a supplier cannot produce a product fuel having a quality that satisfies a required quality ordered by a certain demander X at first, or a supplier that can produce an acceptance material fuel having a quality that satisfies the required quality. Based on the above configuration, information (manufacturing capability information) relating to the quality of the acceptable material fuel or the product fuel that can be manufactured is stored in advance for each supplier in the storage section of the management server, and therefore, in the supplier extraction section, it is possible to exclude from the supplier who cannot manufacture the fuel that must be added to correspond to the order of the demander X initially, regardless of the delivery date. This can prevent a problem that the supplier cannot cope with the solution after the reservation of the fuel supply order for the supplier.

The processing treatment apparatus may be configured to include an apparatus that performs a processing treatment on the certified material fuel to generate the product fuel, and the processing treatment is at least one selected from the group consisting of a foreign matter removal treatment, a mixing treatment, a pulverization treatment, a drying treatment, a classification treatment, and a molding treatment.

As an example, the processing facility may be configured to include:

a crushing apparatus for crushing the acceptance material fuel;

a mixing device for mixing the acceptance material fuels after or before being pulverized by the pulverizing device with each other or mixing the pulverized acceptance material fuels with fuel materials other than the acceptance material fuels; and

a molding device for molding the acceptance material fuel mixed by the mixing device into a pellet shape.

As another example, the processing apparatus may be configured to include:

a foreign matter removing apparatus for removing foreign matter contained in the acceptance material fuel; and

a classification device for classifying the acceptance material fuel after or before being pulverized by the pulverization device.

The product fuel stored in the product placement site is stored in quality classification obtained by range division based on at least one index selected from the group consisting of alkali metal content, chlorine content, water content, and calorific value,

the acceptance material fuel stored in the acceptance material placement site is stored in quality classification obtained by performing range division based on the above-mentioned index,

the quality of demand described in the first order information may be set to be specified based on the index.

Based on the above configuration, the index defining the required quality described in the order from the customer is used in common with the index indicating the quality of the product fuel and the acceptable material fuel stored in the fuel management base by the quality classification. Thus, the stock determination unit can determine whether or not the demand of the customer can be satisfied by a simple calculation from the stock amount of the fuel (product fuel, acceptable material fuel) stored in the current fuel management base.

The fuel management base may be set to have: an analysis device that analyzes the acceptance material fuel and/or the product fuel with respect to a calorific value and/or a prescribed chemical composition.

With such a configuration, when fuel (acceptance material fuel/product fuel) is supplied from a supplier to a fuel management base, even if information on the quality of the fuel is unknown, the quality can be specified by analyzing the fuel in the fuel management base. Thus, the acceptance material placement location or the product placement location as the storage destination of each fuel can be appropriately specified.

In particular, by providing the fuel management base with an analysis device for analyzing the product fuel, it is possible to confirm the quality characteristics of the loaded product loaded on a transportation means such as a ship or a truck and to deliver the product, or to confirm the quality characteristics of the loaded product and then to deliver the product, thereby preventing in advance the delivery of product fuel having a quality that does not meet the specification of the customer.

Note that the same or different analyzing device may be used for the analyzing device for analyzing the acceptance material fuel, the analyzing device for analyzing the product fuel produced by processing the acceptance material fuel, and the analyzing device for analyzing the product fuel to be shipped.

Optionally, the approved material fuel comprises woody biomass from palm oil.

In the fuel control base, the total of the amount of the product fuel that can be stored in the product placement location and the amount of the acceptable material fuel that can be stored in the acceptable material placement location is preferably 1 ten thousand 5 kilotons or more, more preferably 3 ten thousand kilotons or more, and particularly preferably 6 ten thousand kilotons or more. By providing the fuel management base with such a storage capacity, it is possible to store fuel required for several weeks in, for example, a 75MW class biomass power generation boiler.

In the case where the fuel management base includes a mixing facility as one of the processing facilities, the mixing facility may be set to have a function of mixing the pulverized acceptance material fuel with the spent bleaching earth. In this way, granular woody biomass fuel composed of a mixture of woody biomass and spent clay having excellent mechanical strength can also be shipped from a fuel management base.

Effects of the invention

The ordering system based on the invention can not bear the heavy burden on the side of a demander, and can stably provide granular woody biomass fuel which meets the quality required by the demander for the demander.

Detailed Description

First embodiment

Next, a first embodiment of a granular woody biomass fuel ordering system (ordering reservation-reception system) according to the present invention will be described with reference to the drawings. As described above, the "ordering system for granular woody biomass fuel" is sometimes abbreviated as "ordering system".

Fig. 1 is a block diagram schematically showing a configuration of a first embodiment of the ordering system. In fig. 1, the fuel flow is indicated by solid arrows and the information flow is indicated by dashed arrows. The same applies to fig. 11 described later.

As shown in fig. 1, the ordering system 1 has a fuel management base 4 and a management server 5. As described later, the fuel management base 4 stores the fuel supplied by the suppliers 2(2A, 2B, 2C, … …) and the fuel processed and generated by the fuel management base 4. The customer 3(3A, 3B, 3C, … …) is the customer who needs fuel. In the present specification, each demander 3 may be an enterprise unit, an operation office unit, or a demand place unit.

The management server 5 has a function of monitoring the stock state of the fuel stored in the fuel management base 4. Further, when the management server 5 receives order information on the fuel transmitted from the customer 3, information including instructions such as delivery is created (created) as described later and transmitted to the fuel management base 4. More specifically, the management server 5 transmits information including instructions for shipment and the like to the in-base terminal 4p, and the in-base terminal 4p is installed in the fuel management base 4 or carried by an operator who performs work in the fuel management base 4.

Fig. 2 is a block diagram schematically showing an example of the configuration of the fuel management base. The fuel management base 4 has a receiving facility 31, an acceptance material placing site 32, a processing facility 50, an article placing site 34, and a delivery facility 35. The configuration of the fuel management base 4 will be described in detail later.

The fuel management base 4 has the following functions: the fuel transported from the supplier 2(2A, 2B, 2C, … …) is received and stored in the receiving device 31, and the stored fuel is delivered to the consumer 3(3A, 3B, 3C, … …) by the delivery device 35. Requirements 3 are assumed to be: the site where the granular woody biomass fuel is planned to be utilized (fuel demand site) itself, or an operational entity (business, autonomous body, etc.) having the fuel demand site. As an example of such a fuel demand site, biomass power generation is given. Hereinafter, for the sake of simplicity, description will be made in such a manner that the demander 3(3A, 3B, 3C, … …) is the fuel demand site itself.

Supplier 2 is assumed to be: the site itself where the biomass fuel constituting the granular woody biomass fuel or the raw material of the granular woody biomass fuel required by the demander 3 is produced (fuel production site), or an entity (a business, an autonomous entity, or the like) having the fuel production site. Hereinafter, for the sake of simplicity, description will be made in such a manner that the supplier 2(2A, 2B, 2C, … …) is the fuel production site itself.

Examples of supplier 2 include: fuel processing plants installed as accessories in the palm oil industry, processing plants that process low-quality materials produced by mountain finishing, such as woodland leftovers or intermediate cuts, into chips or firewood, processing plants that produce wooden particles or chips from leftovers or sawdust produced by wood factories, waste processing plants that produce wooden particles or chips from wooden waste, such as building waste, or waste pallets, produced during demolition from houses, and the like.

In the present specification, "woody biomass" refers to an organic resource derived from wood: forest leftovers such as branches and leaves generated during tree harvesting or timber fabrication, barks or sawdust generated by timber factories and the like, demolition materials of houses or trimmed branches from street trees and the like. Among these woody biomass, a material having a sufficient calorific value as a fuel, a small content of a contraindication component such as alkali, and a large amount of produced fuel is used as a preferable woody biomass fuel.

In particular, palm empty fruit Ears (EFB), palm trunks (OPT), palm stems and leaves (OPF), Mesocarp Fibers (MF), palm kernel husk (PKS), palm kernel dregs (PKC), palm oil factory waste liquid (POME), and the like, which are woody biomass derived from the palm oil industry prevalent in malaysia and indonesia, generate a good calorific value of 4000kcal/kg or more by drying, and the world production of PKS alone is about 1 million tons (t), and are very preferable as biomass fuels. Note that the calorific value in the present description refers to JIS Z7302-2 "waste solidified fuel — part 2: net calorific value (lower calorific value) described in calorific value test method ".

In the case of using woody biomass as a fuel, it is preferably processed into pellets. By processing into pellets, the pellets have a shape preferable as a fuel, for example, woody biomass fuel is uniform in size; in addition, the heating value increases due to the increase in specific gravity; meanwhile, since drying is easy, the moisture content can be reduced only by placing the container in an environment with low humidity. The granular woody biomass fuel is generally cylindrical with a diameter of about 10mm and a length of about 50mm, and has a calorific value of 3000kcal/kg to 5000 kcal/kg.

The "mechanical strength" of the granular woody biomass fuel in the present specification means a drop strength described in mechanical Durability (DU) described in the standard "woody pellet quality standard" of the japan woody pellet association of the general community, or in the "granulated substance-strength test method" of JIS Z8841, and the mechanical Durability (DU) is 96.5% or more, preferably 97.5% or more, and particularly preferably 98% or more, and the drop strength is 97% or more, preferably 98% or more, and particularly preferably 99% or more, as a mechanical strength that the granular woody biomass fuel should have in order to have preferable handling properties.

Fig. 3 is a block diagram schematically showing an example of the configuration of the management server 5; fig. 4 to 10 are flowcharts for explaining an example of the flow of processing in the ordering system. In the following description, reference will be made as appropriate to the symbols of the steps described in the flowcharts shown in fig. 4 to 10. The detailed arrangement of the fuel management base 4 shown in fig. 2 and the detailed arrangement configuration of the management server 5 shown in fig. 3 will be described together with the description of the processing flow in the ordering system 1.

As shown in fig. 4, the ordering system 1 executes a storing step SA, an order receiving step SB, and a shipping step SC. Step SA is a process of introducing the fuel transported from the supplier 2 into the fuel management base 4 and storing the fuel in the fuel management base 4. The step SB is a step of performing arithmetic processing in the management server 5 based on the order (order) sent from the customer 3. Step SC is a process of delivering fuel from the fuel management base 4 to the customer 3 based on the order (order) sent from the customer 3.

That is, the storage step SA corresponds to the processing performed in the fuel management base 4 regardless of whether or not the fuel ordering is performed by the customer 3 through the ordering system 1. On the other hand, steps SB and SC are processes performed after the fuel order is made by the customer 3 through the ordering system 1. In more detail, step SC includes a fuel delivery process as follows: the management server 5 performs a predetermined arithmetic processing according to the contents of the ordering of the fuel by the customer 3 through the ordering system 1, and then performs a fuel delivery process in the fuel management base 4 according to the information transmitted from the management server 5.

Storage step SA

Fig. 5 is a flowchart showing an example of the flow of processing included in step SA shown in fig. 4.

(step SA10, step SA20)

As described above, the fuel management base 4 receives the fuel transported from the supplier 2 in the receiving apparatus 31.

The reception device 31 preferably has a marine reception device 31a and a land reception device 31 b. The marine vessel receiving facility 31a is a facility for receiving, on the fuel management base 4 side, fuel transported by the supplier 2 by a marine vessel such as a ship. The land transportation reception device 31b is a device for receiving, on the fuel management base 4 side, fuel transported by the supplier 2 by a land transportation means represented by a transportation vehicle such as a truck.

Preferably, the marine receiving facility 31a is constituted by, for example, an estuary cargo handling facility provided in a coast portion, and is provided with a dedicated terminal. The sea receiver 31a is not particularly limited as long as it can receive bulk cargo, and a general unloader such as a grab bucket type, a continuous mechanical type, or a pneumatic type can be used. In particular, a grab bucket is preferable from the viewpoint of being able to handle loads of various shapes and sizes.

A ship dedicated to wood chips (wood chips) is generally equipped with a crane, as an example of the ship. In this way, the sea transport receiver 31a may include a receiving hopper to which a conveyor is attached so as to receive the fuel transported by the cargo ship equipped with a crane.

Thus, for example, when the supplier 2 is a manufacturing site of fuel from palm coconut such as malaysia or indonesia, a large amount of such woody biomass fuel or the like can be received by the marine vessel as the fuel management base 4. Further, by using the marine receiving facility 35a as the marine shipping facility 31a described later, a large amount of product fuel can be shipped to the customer 3 by the ship. Thereby, logistics costs associated with woody biomass fuels can be reduced.

The land transportation receiver 31b is not particularly limited as long as it can be unloaded from various trucks of a Dump (Dump) type or a road traveling type (or slide dock), and a receiving hopper to which a conveyor is attached can be effectively used. In this way, by providing the land use receiver 31b in the receiver 31, it is possible to receive the wood biomass fuel such as the building waste wood, which has been conventionally disposed of in a waste incineration facility or a final landfill in a small amount, by the fuel management base 4, and it is possible to contribute to the construction of the resource recycling society. Further, by using the land transportation receiver 35b as the land transportation delivery device 31b described later, the product fuel can be delivered to the customer 3 who is located in the inland area or has a small demand.

The receiving facility 31 of the fuel management base 4 may be constituted by only one of the marine receiving facility 31a and the land receiving facility 31 b.

Here, the following is assumed as the fuel transported from the supplier 2: the fuel is a fuel (product fuel) granulated in a state having a quality (shippable quality) that can be directly shipped to the customer 3; this fuel is a fuel (acceptable material fuel) that requires processing because it cannot be directly delivered because it has not reached a deliverable quality. This difference is due to the manufacturing and processing capabilities of the supplier 2 (i.e., the fuel manufacturing site), etc.

The "acceptance material fuel" refers to a woody biomass fuel which is not processed into a granular biomass fuel, and specifically refers to: big wood, round wood, small wood, branch bundle, firewood and the like; chips, spiral chips (screening chips), chips and other sheet materials; sawdust such as sawdust and wood shavings; bark (Bark); wood material; waste wood materials such as waste wood materials generated in the process of civil engineering construction, construction waste materials generated in the process of building demolition and the like. The acceptance material fuel is not particularly limited in shape and size, since it is converted into a product fuel by being subjected to a processing treatment such as pulverization or molding in step SA40 described later. Note that, even biomass fuel processed into pellets is included in the acceptable material fuel when the quality of the fuel does not reach a shippable quality, for example, when the mechanical strength is significantly reduced.

The fuel management base 4 has an acceptance material placement site 32 and an article placement site 34. The receiving material placing place 32 is a place where the receiving material fuel is stored, and the product placing place 34 is a place where the product fuel is stored. That is, when fuel (product fuel) having a quality that can be delivered is transported from the supplier 2 to the fuel management base 4, the fuel is stored in the product placement site 34. On the other hand, in the case where fuel (acceptance material fuel) that does not reach the shippable quality is transported from the supplier 2 to the fuel management base 4, the fuel is stored in the acceptance material placement site 32.

The fuel management base 4 has a plurality of accepted material placement sites 32(32a, 32b, 32c, … …). In these acceptable material placement sites 32, the quality of the acceptable material fuel to be stored is different. That is, one of the acceptable material placement places 32a corresponds to a storage place for the acceptable material fuel having the quality level Qa, and the other acceptable material placement place 32b corresponds to a storage place for the acceptable material fuel having the quality level Qb.

(step SA30)

After receiving the acceptance material fuel from the supplier 2, the fuel management base 4 specifies the acceptance material placement site 32 to be stored according to the quality of the acceptance material fuel, and transports and stores the acceptance material fuel in the specified acceptance material placement site 32.

Fig. 6 is a flowchart showing an example of the flow of the processing included in step SA 30. In the example shown in fig. 6, step SA30 includes the processes of step SA32, step SA33, step SA34, step SA35, and step SA 36.

First, a part of the approved material fuel is extracted from the large amount of approved material fuel transported from supplier 2 (step SA 32). For example, as shown in fig. 2, the fuel management base 4 may include a sampler 43 for acceptable material fuel for performing step SA 32. The sampler 43 for acceptance of the material fuel is a sample collecting device for analysis and test, and the sampling method and the like are not particularly limited as long as a representative sample can be collected. In general, as described in JIS K0060 "collection method of industrial waste" and JIS M8100 "general rule of powder mix-sampling method", it is preferable to use a sampler capable of collecting objects falling from a falling port of a conveyor belt or a feeder over a total flow width.

Next, the acceptance material fuel extracted in step SA32 is subjected to predetermined analysis processing (step SA 33). For example, as shown in fig. 2, the fuel management base 4 may have an analyzing device 41 for performing step SA 33.

The analyzing device 41 is not particularly limited as long as it can cope with a desired test and analysis item, and a general-purpose test device or analyzing device can be used. The analysis device 41 may be configured to be unmanned by a robot operation automation system or the like. As an example, the analyzing device 41 has a function of testing and analyzing the alkali metal content, chlorine content, moisture content, and calorific value of the test material fuel.

In the measurement of the amount of chemical components (alkali metal, chlorine, etc.) contained in the test material fuel, there is no particular limitation as long as an analysis method capable of obtaining a desired amount of chemical components is employed, but from the viewpoint of versatility and analysis accuracy, it is preferable to use an absorption spectrophotometry, an emission spectrophotometry, an atomic absorption spectrophotometry, or an ICP emission spectrophotometry relating to a solution in which a sample or an ashed sample is completely dissolved by an acid. In addition, the chlorine content can be measured using JISZ 7302-6 "waste solidified fuel — part 6: test methods in Total chlorine content test methods ". It is noted that ashing of the biomass fuel is preferably performed at a low temperature of 600 ℃.

In addition, in the measurement of the amount of water (or the water content) contained in the acceptance material fuel, for example, JIS Z7302-3 "waste solidified fuel-part 3: the method described in "Water test method". Specifically, the mass before and after heating in the case of heating at a drying chamber temperature of 107 ± 2 ℃ for 1 hour may be used. Furthermore, the analysis can be performed by an instrument such as a thermobalance analysis (TG).

In addition, in the measurement of the calorific value of the acceptance material fuel, for example, JIS Z7302-2 "waste solidified fuel — part 2: the method described in the calorific value test method ".

The analyzing device 41 does not necessarily have all of the analyzing functions of the amount of alkali metal, the amount of chlorine, the amount of moisture (water content), and the calorific value contained in the acceptance material fuel, and may have at least one of the analyzing functions.

Note that, as a method of transporting the acceptance material fuel extracted by the sampler 43 for acceptance material fuel to the installation site of the analysis device 41, there is no particular limitation, and a pneumatic transport pipe system or the like capable of automatically transporting a sample is preferably used.

Next, the quality of the subject acceptance material fuel is specified based on the result of the analysis by the analysis apparatus 41 in step SA33 (step SA 34).

The quality of the acceptable material fuel may be specified by any quality item and any number of grades in each quality item. For example, the following method can be employed: when the three items of the calorific value, the moisture content, and the alkali content are selected, the two items of the calorific value and the moisture content which can be processed relatively easily are classified into two levels of sizes determined by specific threshold values, and the alkali content which is difficult to process is classified into three levels of large, medium, and small, and the whole is classified into 12 (2 × 2 × 3), in consideration of the difficulty in the processing performed in step SA40 described later. The classified items may also include chlorine content.

Next, based on the quality of the certified material fuel specified in step SA34, a certified material placing location 32 as a storage destination of the certified material fuel is selectively specified from among the respective certified material placing locations 32(32a, 32b, 32c, … …) (step SA 35).

As described above, the quality of the acceptable material fuel to be stored differs in each acceptable material placement site 32. The information on the quality of the acceptable material fuel distributed to each acceptable material placement site 32 may be stored in advance on a storage section or a paper surface of an information processing device not shown in the drawings. In the former case, the following may be set: the operator of the fuel management base 4 can confirm the information on the quality of the acceptable material fuel distributed to each acceptable material placement site 32 using the in-base terminal 4p described later.

An acceptance material placing place 32 as a storage destination of the acceptance material fuel is specified based on the stored information. Note that, when the quality of the acceptable material fuel specified in step SA34 reaches the above-described shippable quality, the acceptable material fuel may be stored in a predetermined product placement location 34, or one placement location (for example, the acceptable material placement location 32a) of the acceptable material placement locations 32 may be used as the product placement location 34.

And, the acceptance material fuel is transported and stored to the acceptance material placing site 32 specified in step SA35 (step SA 36). Note that, when transporting fuel (acceptance material fuel/product fuel) in the fuel management base 4, for example, when transporting the acceptance material fuel from the receiving facility 31 to the acceptance material placement site 32, heavy machinery such as a wheel loader or a bulldozer or pneumatic machinery can be used, but from the viewpoint of efficiency, work safety, prevention of scattering of woody biomass fuel, equipment cost, and the like, conveyors such as a belt conveyor or a screw conveyor are preferably used. Note that since a sheet or the like is likely to cause a jam state called Bridging (Bridging), it is preferable to take measures such as a flapper to prevent the jam in a place having a narrow path or the like.

The receiving material placing place 32 is not particularly limited as long as it is a facility capable of storing the received woody biomass fuel, i.e., the receiving material fuel, without causing it to be wetted by rain or the like and smoothly performing receiving and loading, and a roofed building or silo (ensiling tower) can be effectively used. From the viewpoint of preventing water from wetting and spontaneous combustion during storage, a storage facility that can introduce dry gas or a turning device provided with a pile of woody biomass fuel into a storage space as described in patent No. 6381836 and the like is more preferable. Note that, in the case of using a roofed building as the acceptance material placing place 32, a plurality of kinds of acceptance material fuels can be stored in one building as long as management can be performed so that the acceptance material fuels classified by quality do not mix with each other.

Depending on the supplier 2, the fuel management base 4 may be provided with a function of analyzing the quality of the fuel (acceptable material fuel or product fuel) transported thereto. At this time, the supplier 2 may notify the fuel management base 4 of information on the quality of the transported fuel. More specifically, the following may be set: the operator in the fuel management base 4 can check information on the quality of the fuel transported from the supplier 2 using a base terminal 4p described later.

In the above case, it is possible to specify the acceptable material placement location 32 as the storage destination of the acceptable material fuel based on the information on the quality of the acceptable material fuel notified from the supplier 2, and store the acceptable material fuel in the specified acceptable material placement location 32 (steps SA35, SA 36). In this case, the following may be set: it is not necessary to perform an analysis process for the acceptance material fuel (step SA33) and a specified process based on the quality of the analysis result (step SA34) in the fuel management base 4.

(step SA40)

Then, the quality improvement processing is performed by performing processing on the acceptance material fuel stored in the acceptance material placement site 32, thereby producing a fuel (product fuel) of a quality that can be delivered. As shown in fig. 2, the fuel management base 4 includes a processing facility 50 for executing step SA 40.

For example, the acceptance material fuel having a small calorific value is subjected to mixing processing with another acceptance material fuel having a large calorific value. For the acceptance material fuel with a large moisture content, drying treatment is performed. For the acceptance material fuel having a large alkali content, a mixing process with other acceptance material fuel having a small alkali content is performed. For the acceptance material fuel not processed into the granular form, after each process of the foreign matter removal, the pulverization process and/or the classification process is performed, the molding process is performed to make it into the granular form.

That is, the processing treatment includes a foreign matter removal treatment, a mixing treatment, a pulverization treatment, a drying treatment, a classification treatment, a molding treatment, and the like. In step SA40, all of these processes may be executed, or only a part of them may be executed.

Fig. 7 is a block diagram schematically showing an example of the configuration of the processing facility 50. In the example shown in fig. 7, the processing apparatus 50 is configured to have a foreign matter removing apparatus 51, a mixing apparatus 52, a pulverizing apparatus 53, a drying apparatus 54, a classifying apparatus 55, and a forming apparatus 56.

The foreign matter removing apparatus 51 is an apparatus for removing foreign matters such as hard wood chips such as knots, earth and stone, and metals contained in the acceptance material fuel as the non-granular woody biomass fuel, and is an apparatus for performing the above-described foreign matter removing process. The foreign matter removing means 51 is not limited in the form of the apparatus and the principle of separation as long as it can perform the above-described functions, and one or more kinds of apparatuses such as a sieve, a gravity classifier, a centrifugal classifier, a winnowing machine, and a magnetic separator may be used alone or in combination.

The mixing device 52 is a device for dry-mixing the accepted material fuels with each other, and is a device for performing the above-described mixing process. As the mixing device 52, heavy equipment such as a wheel loader, a blade mixer having a fiber opening effect, a rotary screen having a classifying function of a classifying device 55 described later, a twin-screw kneading extruder having a molding function of a molding device 56 described later, or the like can be effectively used as long as the above-described functions can be achieved, that is, the device form is not limited.

The pulverizing apparatus 53 is an apparatus for pulverizing, crushing and thinning the accepted material fuel having problems in mechanical strength, size and the like to a diameter of the die orifice of the molding apparatus 56 or less, and is an apparatus for performing the above-described pulverizing process. As the pulverizing means 53, a roll mill, a ball mill, a pusher mill (single shaft, double shaft), a blade type (chipping type), a hammer type (chipping type) or hammer blade type (chipping type) chip making machine (wood chipper), a hammer mill or the like can be used alone or one or more devices can be used continuously as long as the above-described functions can be achieved, that is, the device form and the crushing principle are not limited.

The drying apparatus 54 is an apparatus for drying the acceptance material fuel, and is an apparatus for performing the above-described drying process. The drying equipment 54 may be any equipment dedicated to the above-described functions, that is, the type of equipment and the principle of drying, and may be a place where the temperature can be controlled by using heat such as exhaust heat, or a place where natural drying such as sun drying and indoor drying can be easily performed, in addition to a special equipment such as a hot air shower device, a box dryer, a belt fluidized bed dryer, a rotary dryer, and a Wedge dryer (Wedge dryer). In addition, a forced pulverizing dryer such as an arm-type impact pulverizing dryer, a hammer-type impact pulverizing dryer, or a chain-type impact pulverizing dryer, which has the pulverizing function of the pulverizing device 53, may be used.

The temperature for the drying treatment can be 175 ℃ or lower. This also provides the following effects: since the temperature of the woody biomass fuel becomes sufficiently high (for example, 80 ℃ or higher) at the time of the drying treatment, the woody biomass fuel can be sterilized even if microorganisms are present therein. On the other hand, when the temperature of the woody biomass fuel exceeds 175 ℃, the biomass fuel may accumulate heat and cause thermal runaway to cause fire. Thus, the drying temperature is preferably 80 ℃ or higher and 175 ℃ or lower.

The classifying device 55 is not particularly limited as long as it is a dry device capable of separating the acceptable material fuel into different sizes, and a vibrating or rotating sieve can be preferably used.

The molding device 56 is a device for molding the acceptance material fuel itself received by the receiving device 31 or the small-sized product or pulverized product of the acceptance material fuel obtained by the pulverizing device 53 and/or the classifying device 55 to produce a granular woody biomass fuel of a predetermined size. The forming device 56 is generally composed of a die having a plurality of cylindrical small holes and a compression roller, and the pulverized sheet or the like is pressed into the small holes by the compression roller to be formed into pellets. The die is classified into a ring die system and a flat die system according to the shape of the die, and any system may be used.

For example, even if the fuel transported from the supplier 2 is a granular woody biomass fuel, the quality may not be shippable, for example, the water content exceeds 15 mass%, or the mechanical strength is lowered by wetting with water. That is, the following is assumed: the granular woody biomass fuel transported from the supplier 2 is not a product fuel but is considered to be an acceptance material fuel.

For example, in the case where the water content is more than 15 mass%, the granular woody biomass fuel may be treated as an acceptance material fuel and subjected to a drying treatment in this step SA 40. Note that if the water content of the granular woody biomass fuel is 15 mass% or less, the granular woody biomass fuel has a mechanical strength capable of sufficiently withstanding mechanical impact received during transportation or the like and retaining its own shape, and does not cause a problem in handling properties. Therefore, the granular woody biomass fuel having a water content of 15 mass% or less may not be subjected to the drying treatment.

Further, the acceptable material fuel as the granular woody biomass fuel whose mechanical strength is lowered by wetting with water or the like may be formed into granules after being subjected to a pulverization treatment or the like. For example, in the case of a granular woody biomass fuel, if the water content exceeds 40 mass%, a collapse phenomenon due to swelling occurs, and it is difficult to maintain the granular shape even if the above-mentioned drying treatment is performed. Therefore, even if the moisture content of the biomass fuel in this state is reduced by drying, the biomass fuel may be decomposed into powder or short fibers, and it is difficult to recover the operational characteristics. Thus, when the water content of the granular woody biomass fuel is 40 mass% or more, the granular woody biomass fuel may be decomposed into a short fiber form by pulverization or the like, then dried, and then molded into a granular form again.

(step SA50)

Next, with respect to the product fuel generated in step SA40 and the product fuel received in step SA20, the product placement site 34(34a, 34b, 34c, … …) as the storage destination is specified in accordance with the quality, and the product fuel is transported and stored at the specified product placement site 34.

Fig. 8 is a flowchart showing an example of the flow of the processing included in step SA 50. In the example shown in fig. 8, step SA50 includes the processes of step SA52, step SA53, step SA54, step SA55, and step SA 56.

First, a part of the product fuel is extracted from a large amount of the product fuel whose storage destination is to be determined (step SA 52).

For example, as shown in fig. 2, the fuel management base 4 may include a product fuel sampler 44 for executing step SA 52. The product fuel sampler 44 may be configured in the same manner as the above-described acceptance material fuel sampler 43. Note that the sampler 43 for acceptance material fuel may double as the sampler 44 for product fuel.

Next, the extracted product fuel is analyzed (step SA 53). In the example shown in fig. 2, the following is shown: the product fuel extracted by the sampler 44 for product fuel is analyzed by the same analyzing apparatus 41 as that of step SA 33. The fuel management base 4 may be provided with a dedicated analysis device 41 for executing the processing at step SA53, which is different from the analysis device 41 used at step SA 33.

In step SA53, the alkali metal content, chlorine content, water content, and calorific value of the product fuel may be tested and analyzed in the same manner as in step SA 33. However, in the case of the product fuel produced through the processing in step SA40, for example, the moisture content of all the product fuels may be made to satisfy the quality level by performing the drying process. In this case, in step SA53, for example, only two items, that is, the calorific value and the alkali metal content, may be analyzed without analyzing the water content.

Next, the quality of the target product fuel is specified based on the result of the analysis performed by the analysis device 41 (step SA 54).

As a method for specifying the quality of the product fuel, it is sufficient to perform the specification in accordance with any quality item and any number of ranks in each quality item, as in the method for specifying the quality of the acceptable material fuel described in step SA 34. However, as described above, since the water content of all product fuels may satisfy the standard, it is possible to limit the fuel to two items such as the calorific value and the alkali content. In addition, for these limited quality items, a quality level corresponding to the requested quality of the customer side may be set, and in most cases, two levels of the size may be set for most of the quality items. Therefore, in the case where two items, that is, the calorific value and the alkali content, are taken as quality items to be managed of a product, a method of totally classifying the product fuel into 4 categories (═ 2 × 2) can be adopted.

Next, based on the quality of the product fuel specified in step SA54, the product placement site 34 that is the storage destination of the product fuel is selectively specified from among the product placement sites 34(34a, 34b, 34c, … …) (step SA 55). As described above, the quality of the product fuel to be stored differs among the product placement locations 34. The information on the quality of the product fuel distributed to each product placement site 34 may be stored in advance on a storage section or a paper surface of an information processing device not shown in the drawings. In the former case, it can be set as: the operator of the fuel management base 4 can confirm information on the quality of the product fuel distributed to each product placement site 34 using the in-base terminal 4p described later. The product placement site 34 as the storage destination of the product fuel is specified based on the stored information.

Then, the product fuel is transported to the designated product placement site 34 and stored (step SA 56). Note that, as with the acceptance material placement site 32(32a, 32b, 32c, … …), the product placement site 34(34a, 34b, 34c, … …) is not particularly limited as long as it can store the received wooden biomass fuel, i.e., the acceptance material fuel, without causing it to be wet by rain, and can smoothly carry out receiving and loading, and a roofed building or silo can be effectively used.

Procedure for receiving order SB

Fig. 9 is a flowchart showing an example of the flow of the processing included in step SB shown in fig. 4. In addition, in explaining the present step SB, a block diagram showing a configuration of the management server 5 shown in fig. 3 is appropriately referred to.

The management server 5 is configured by a general-purpose computer having an arithmetic processing function and a storage function. In the example of fig. 3, the management server 5 includes a storage unit 11, an inventory determination unit 12, a shipment processing instruction creation unit 13, an inventory update unit 14, a processing result calculation unit 15, a product mixture result calculation unit 16, and an order reception unit 17.

The storage unit 11 is an area for storing predetermined information (predetermined information), and is configured by a storage medium such as a flash memory or a hard disk. The stock determination unit 12, the shipping/processing instruction creation unit 13, the stock update unit 14, the processing result calculation unit 15, the product mix result calculation unit 16, and the order reception unit 17 are arithmetic processing units that perform predetermined signal processing (calculation) based on the acquired information, and are configured by dedicated software and/or hardware.

As schematically shown in fig. 1, each of the customers 3(3A, 3B, 3C, … …) has a customer terminal 3p (3Ap, 3Bp, 3Cp, … …) for inputting an order (order) in which required fuel information is recorded. The demander terminal 3p is a terminal that can communicate with the management server 5, and is configured by a portable terminal such as a smartphone in addition to a general-purpose computer. The communication format between the consumer terminal 3p and the management server 5 is not limited in kind, and any communication format such as the internet or Wi-Fi (registered trademark) may be used.

(step SB1)

The customer 3(3A, 3B, 3C, … …) uses the customer terminal 3p (3Ap, 3Bp, 3Cp, … …) to send an order (order) in which the required fuel information is recorded. Specifically, when the customer 3 wants to order fuel, after registering in the regulation system, necessary fuel-related information (hereinafter referred to as "first order information dO 1") is input. Thereby, the first order information dO1 input by the demander 3 is transmitted to the management server 5 through a predetermined communication line.

The first order information dO1 includes information on the quality and quantity of fuel (product fuel) required by the customer 3. Hereinafter, the quality of fuel required by the customer is referred to as "required quality", and the amount of fuel required by the customer is referred to as "required amount".

The required quality described in the first order information dO1 is preferably specified by using the same index as the index of quality used for determining the storage destination of the product fuel or the acceptable material fuel in the fuel management base 4. That is, the demander 3 can be set to: the required quality is specified based on a value of a level (rank) classified by a predetermined threshold value for any or more of the alkali metal content, chlorine content, moisture content, and calorific value.

For example, it can be set as: when the customer terminal 3p inputs a fuel order (order), it is required to utilize an application or web site corresponding to the ordering system 1. At this time, the application or web site may be set to: a system is required that specifies a level corresponding to the demand quality of the customer 3 from among a plurality of levels classified in advance in the above-described manner.

The management server 5 has an order (order) receiving section 17 for receiving the first order information dO1 transmitted by the demander 3. The order receiving section 17 includes: the interface unit for receiving the first order information dO1 accurately analyzes the content of the received first order information dO1 and outputs the analyzed content to the arithmetic processing unit of the stock determination unit 12. Further, it may be set that a predetermined authentication procedure is required before the first order information dO1 is transmitted from the demander terminal 3 p; in this case, the order reception section 17 may be set to have the authentication processing function described above.

First order information dO1 may be set to include identification information for identifying requester 3 as a reservation order originator.

(step SB2)

The inventory determination unit 12 determines whether or not the order of the customer 3 can be dealt with, that is, whether or not the delivery can be performed, based on the content of the first order information dO1 transmitted from the customer 3 and the current amount of fuel stored in the fuel management base 4.

As shown in fig. 3, the management server 5 includes a storage unit 11. In the present embodiment, the storage portion 11 has a fuel stock storage area 11 a. In the fuel stock storage area 11a, there are stored: information (first stock quantity information dS1) relating to the stock quantity by quality of the product fuel currently stored in the product placement site 34(34a, 34b, 34c, … …) of the fuel management base 4, and information (second stock quantity information dS2) relating to the stock quantity by quality of the acceptance material fuel stored in the acceptance material placement site 32(32a, 32b, 32c, … …) of the fuel management base 4 stored by quality.

The stock determination unit 12 first reads the first stock quantity information dS1 from the storage unit 11, and determines whether or not the order described in the first order information dO1 can be dealt with based on the stock of the product fuel stored in the product placement site 34 (step SB2 a).

For example, when the first order information dO1 describes that the demand quality is QB and the demand amount is M1, the inventory determiner 12 refers to the first stock quantity information dS1 to determine whether or not the demand amount M1 or more is stored in the product fuel assembly site 34 of quality QB. When the current stock quantity can be handled (Yes in step SB2a), the shipping instruction creation unit 13 transmits instruction information indicating that fact to the base station terminal 4p (step SB 3).

Further, when the required quality described in the first order information dO1 is QB, the inventory determination unit 12 may determine that the current inventory amount is available when the total of the inventory amounts in the product placement location 34 of the product fuel having a quality equal to or higher than QB is equal to or higher than the required amount M1. Wherein it is envisaged that: the higher the quality of the product fuel, the higher the supply price from the supplier 2, or the higher the accuracy of the processing performed in step SA40, and therefore the higher the fuel unit price is set. Therefore, the inventory determination unit 12 may be set to perform appropriate setting according to the relationship with the customer 3, in order to determine whether or not the current inventory amount of the product fuel is acceptable, in addition to including the amount of the product fuel having the quality exceeding the required quality described in the first order information dO 1.

In addition, when the demand quality described in the first order information dO1 is QB, it is assumed that there are the following cases: although a sufficient amount of product fuel showing quality QB is not stored in the product placement site 34, a sufficient amount of product fuel showing quality QA higher than quality QB and a sufficient amount of product fuel showing quality QC lower than quality QB are stored. In this case, the inventory determination unit 12 may be configured to: the quality obtained when product fuels of specified qualities (quality QA and quality QC in this case) are mixed by a predetermined amount is calculated in the product mixture result calculation unit 16, and the calculation result is also considered to determine whether or not the fuel can be handled by the current stock amount.

The product mixture result calculation unit 16 has the following functions: the quality and amount of the product fuel to be mixed are calculated based on, for example, information on the quality of the product fuel to be mixed, information on the stock quantity of the product fuel showing the quality, and information on the required quality and required amount described in the first order information dO 1. As an example, the quality of the product fuel obtained by mixing is specified according to the ratio of the quality-classified amounts of the product fuels to be mixed.

If it is determined that the order described in the first order information dO1 cannot be dealt with based on the stock of the product fuel stored in the product placement location 34 (No in step SB2a), the stock determination unit 12 then determines whether or not the shortage can be dealt with based on the stock of the acceptable material fuel stored in the acceptable material placement location 32 (step SB2 b).

For example, when the first order information dO1 describes that the demand quality is QB and the demand amount is M1, it is assumed that only M1 is insufficient for the product fuel of quality QB stored in the product placement site 34 at present. In this case, when the product fuel produced by processing the certified material fuel stored in the current certified material placement site 32 by the processing equipment 50 is included, it is assumed that the insufficient amount m1 is satisfied. In this case, the inventory determination unit 12 may be configured to: the quality of the product fuel produced by processing the acceptable material fuel of a predetermined quality is calculated by the processing result calculation unit 15, and the calculation result is also considered to determine whether or not the product fuel can be handled by the current stock quantity.

As described above, the storage unit 11 stores: second inventory amount information dS2 relating to the inventory amount classified by quality of the current acceptance material fuel. The machining result calculation unit 15 has the following functions: the quality and quantity of the acceptable material fuel to be processed for supply of the treatment shortage are determined based on the information on the required quality, the information on the shortage, and the second stock quantity information dS 2.

For example, the machining result calculation unit 15 stores: the correspondence relationship (hereinafter referred to as "processing correspondence relationship information") between the quality of the acceptable material fuel stored in the acceptable material storage location 32 and the quality of the product fuel produced by processing the acceptable material fuel exhibiting the quality. For example, when the quality Qb product fuel is produced by processing the quality Qb acceptable material fuel stored in the acceptable material placement site 32, the stock determination unit 12 can determine whether the processing can be performed to supply the product fuel indicated as the shortage of the required quality Qb based on the stock quantity of the quality Qb acceptable material fuel.

In addition, it is also conceivable that acceptance material fuels having different qualities are mixed and processed to produce a product fuel. In this case, the machining result calculation unit 15 may be configured to: and calculating the quality of the product fuel obtained by processing according to the stored processing corresponding relation information and the ratio of the quality-classified quantity of the acceptance material fuel used for processing.

When the stock determination unit 12 determines that the processing shortage can be dealt with from the stock of the acceptable material fuel stored in the acceptable material placement site 32 based on the calculation result in the processing result calculation unit 15 by the above-described method (yes in step SB2b), the shipment processing instruction creation unit 13 transmits instruction information of the intention to the base terminal 4p (step SB 5).

(step SB3, step SB5)

When the stock determination unit 12 determines that the demand of the customer 3 can be satisfied from the stock of the product fuel (yes in step SB2a) or when it determines that the demand of the customer 3 can be satisfied by using the certified material fuel in stock (yes in step SB2b), the in-base terminal 4p receives the instruction information (machining instruction information d4) transmitted from the machining instruction creation unit 13 (steps SB3 and SB 5).

The shipping processing instruction information d4 describes: information relating to the amount classified by quality of the product fuel required for shipment (first consumption information), and/or information relating to the amount classified by quality of the accepted material fuel required for the processing for shipment (second consumption information). These first consumption amount information and second consumption amount information are created (created) by the shipping processing instruction creating unit 13 based on the result obtained when step SB2a or step SB2b is executed.

Then, in the fuel management base 4, the shipping process is performed after the processing process is performed as necessary. This process corresponds to the above step SC in fig. 4. Details of step SC will be described later with reference to fig. 10.

The shipping instruction information d4 transmitted from the shipping instruction creation unit 13 to the base terminal 4p may be set to: the identification information for specifying the demander 3 is contained in addition to the first consumption amount information or the second consumption amount information. It can also be set as follows: the information containing the content for confirming the first order information dO1 sent by the demander 3 to the management server 5 is merged. For example, when the first order information dO1 includes information on the delivery date requested by the requester 3, it may be set as: information on the delivery required date is included in the shipping instruction information d 4.

The shipping/processing instruction information d4 may include the content of the first order information dO1, or may be set to include address information as a link destination in the management server 5 for confirming the content of the first order information dO 1. In the latter case, the operator of the fuel management base 4 can access the link destination by operating the in-base terminal 4p to confirm the first order information dO1 transmitted by the demander 3.

(step SB4)

As described above, the management server 5 includes the stock update unit 14. When the shipping instruction creation unit 13 transmits the shipping instruction information d4 to the terminal 4p in the base (step SB3, step SB5), the stock update unit 14 updates the information in the storage unit 11 based on the shipping instruction information d 4. Specifically, the stock update unit 14 updates the content of the information (first stock information dS1) on the stock quantity by quality of the product fuel stored in the storage unit 11, based on the first consumption amount information described in the shipment process instruction information d 4. Similarly, the stock update unit 14 updates the content of the information (second stock information dS2) relating to the stock quantity by quality of the acceptable material fuel stored in the storage unit 11, based on the second consumption amount information described in the shipment destination instruction information d 4.

By executing this step SB4, the storage unit 11 of the management server 5 stores information on the stock quantity of the fuel stored in the fuel management base 4 in a state where the reduction in the amount of fuel delivered from the fuel management base 4 to the customer 3 is reflected.

(step SB6)

Further, according to the contents of the first order information dO1, it is conceivable that there is a case where the fuel stock stored in the current fuel management base 4 cannot satisfy the demand (no in step SB2 b). In this case, the supplier 2 is subjected to a reserved ordering process of the fuel.

In the present embodiment, this step SB6 includes a case where it is not automatically executed via the management server 5. That is, the person in charge who manages the management server 5 can create order information for the supplier 2 alone and perform order processing. Further, the management server 5 may be set to: the ordering process is performed after the supplier 2 as an order destination (object) is automatically selected. This configuration will be described later in the second embodiment.

Delivery procedure SC

Fig. 10 is a flowchart showing an example of the flow of processing included in step SC shown in fig. 4. In addition, in explaining the present step SC, a block diagram showing the configuration of the fuel management base 4 shown in fig. 2 is appropriately referred to.

Step SC1

The in-base terminal 4p receives the machining instruction information d4 transmitted from the machining instruction creation unit 13 in step SB3 or step SB5 (step SC 1). For example, as described above, the terminal 4p in the base is installed or carried in a state in which it is recognizable by the operator in the fuel management base 4, and when the finishing instruction information d4 is transmitted from the management server 5, the operator in the fuel management base 4 can confirm the contents of the finishing instruction information d 4.

(step SC2, step SC3)

The operator in the fuel management base 4 confirms whether or not the delivery/processing instruction information d4 includes an instruction to process the received material fuel by using the in-base terminal 4p (step SC 2). If the processing is not included (no in step SC2), it is further checked whether or not the shipping/processing instruction information d4 includes an instruction indicating the intention to perform the mixing of the product fuels of different qualities (step SC 3).

(step SC4)

If the shipping instruction information d4 does not include an instruction to indicate the intention to mix the produced fuels of different qualities (no in step SC3), the product placement location 34 in which the produced fuels of the qualities described in the shipping instruction information d4 are stored is designated (step SC 4).

(step SC5)

Then, a confirmation operation is performed as necessary to confirm that the product fuel stored in the designated product placement site 34 shows the required quality. This step SC5 may be omitted.

First, a part of the product fuel is extracted from the large amount of product fuel stored at the designated product placing place 6 (step SC5 a). For example, as shown in fig. 2, the fuel management base 4 may include a sampler 45 for shipment for executing step SC5 a. The sampler 45 for the shipment product can be configured in the same manner as the above-described sampler 43 for the acceptance material fuel or the sampler 44 for the product fuel. Note that the sampler 43 for acceptance material fuel and/or the sampler 44 for product fuel may also double as the sampler 45 for product.

Next, the extracted product fuel is analyzed (step SC5 b). In the example shown in fig. 2, the case where the product fuel extracted in the sampler 45 for shipment is analyzed by the same analyzing device 41 as that of step SA33 is shown. The fuel management base 4 may have a dedicated analyzing device 41 for execution in step SC5b, which is different from the analyzing device 41 used in step SA33 and/or step SA 53.

Next, based on the result of the analysis performed by the analyzing device 41, the quality of the product fuel extracted by the sampler 45 for the shipment item is specified, and it is confirmed whether or not the specified quality reaches the required quality (step SC5 c). When the target product fuel does not reach the required quality, the base station terminal 4p may transmit alarm information to the management server 5.

(step SC6)

In step SC5, when it is confirmed that the target product fuel has reached the required quality, a large amount of the product fuel stored in the product placement site 34 is transported to the delivery device 35. As described above, step SC5 may be omitted, and in this case, a large amount of product fuel stored at product placement site 34 specified in step SC4 is transported to delivery device 35.

The shipping device 35 preferably has a marine shipping device 35a and a land shipping device 35 b. The shipping facility for marine use 35a is not particularly limited as long as it is a facility capable of shipping according to the packaging system, such as a ship loader for bulk cargo, a crane or a crane for containers or bulk bags, or the like. The land transportation shipping equipment 35b is not particularly limited as long as it can be shipped according to a packaging method, such as a hopper for loading bulk trucks and a forklift for handling bulk bags.

The delivery device 35 of the fuel management base 4 may be configured by only one of the marine delivery device 35a and the land delivery device 35 b.

(step SC7)

The product fuel is shipped from the marine delivery facility 35a to the customer 3 by a marine vehicle such as a ship, and shipped from the land delivery facility 35b to the customer 3 by a land vehicle represented by a transport vehicle such as a truck.

(step SC8)

When the shipping/processing instruction information d4 includes an instruction indicating the intention to perform mixing processing of product fuels of different qualities (yes in step SC3), a predetermined amount of product fuel is extracted from the product storage location 34(34a, 34b, 34c, … …) where the product fuels of the designated qualities are stored and mixed.

Then, after the confirmation process of step SC5 is performed as necessary, step SC6 and step SC7 are performed.

(step SC9)

If the shipping/processing instruction information d4 includes an instruction of an intention to perform processing on the acceptable material fuel (yes in step SC2), a predetermined amount of acceptable material fuel is taken out from the acceptable material storage location 32(32a, 32b, 32c, … …) where the acceptable material fuel of a predetermined quality is stored, and the processing facility 50 performs processing by the same method as in step SA 40. Thereby producing a product fuel.

Then, after the confirmation process of step SC5 is performed as necessary for the product fuel, steps SC6 and SC7 are performed. Further, since the product fuel produced by this processing is a predetermined fuel to be immediately shipped, it does not necessarily need to be stored in the product placement site 34 unlike step SA 50. If it takes time to deliver the fuel before it is determined that the fuel is stored in the product storage location 34 according to the quality of the product fuel to be produced; alternatively, the fuel may be stored in a dedicated product storage location 34 for temporarily storing the fuel to be delivered.

Second embodiment

Next, a second embodiment of the ordering system (ordering reservation-reception system) for granular woody biomass fuel according to the present invention will be described with emphasis on the difference from the first embodiment.

Fig. 11 is a block diagram schematically showing the configuration of the second embodiment of the ordering system. As shown in fig. 11, the ordering system 1 in the present embodiment is different from the first embodiment in that it includes a supplier terminal 2p (2Ap, 2Bp, 2Cp, … …) with which the supplier 2(2A, 2B, 2C, … …) can communicate with the management server 5.

Fig. 12 is a block diagram schematically showing an example of the configuration of the management server 5 including the ordering system 1 according to the present embodiment; unlike the first embodiment, the management server 5 includes a shortage amount calculation unit 18, a supplier extraction unit 19, and a supplier reservation ordering unit 20. The shortage amount calculation unit 18, the supplier extraction unit 19, and the supplier reservation ordering unit 20 are all arithmetic processing units that perform predetermined signal processing (arithmetic) based on the acquired information, and are configured by dedicated software and/or hardware.

In the present embodiment, the storage unit 11 includes a processing information storage area 11b and a supplier information storage area 11c in addition to the fuel stock storage area 11 a. The processing information storage area 11b stores information (processing time information dP) relating to processing time required for the processing facility 50 to perform processing on the received material fuel and generate a product fuel. The supplier information storage area 11c stores: information on the transportation time required to transport the fuel to the fuel management base 4 from the site of each supplier 2 (transportation time information dD), and information on the quality of the fuel that each supplier can manufacture (manufacturing capability information dM).

The ordering system 1 of the present embodiment is different from the first embodiment in that the management server 5 has a function of automatically extracting the supplier 2 as an order reservation receiver and then performing an order reservation process to the supplier 2 in step SB6 described with reference to fig. 9, and is common to the first embodiment. Next, the contents of step SB6 will be described.

Fig. 13 is a flowchart for explaining an example of the flow of the processing included in step SB6 executed in the ordering system 1 in the present embodiment.

(step SB6a)

If the stock determination unit 12 determines that the current fuel stock amount of the fuel management base 4 cannot satisfy the demand described in the first order information dO1 (refer to no in step SB2b in fig. 9), the deficiency amount calculation unit 18 determines the amount of fuel that needs to be added (deficiency amount).

For example, the shortage calculation unit 18 calculates, from the content determined by the stock determination unit 12 through calculation in step SB2 (see fig. 9), the shortage (first shortage) of the product fuel classified by quality that needs to be added to satisfy the demand described in the first order information dO1 only with the product fuel. For example, the deficiency amount calculating unit 18 calculates, based on the content determined by the stock determining unit 12 through calculation in step SB2, a deficiency amount (second deficiency amount) of the acceptable material fuel classified by quality that needs to be added to satisfy the demand described in the first order information dO1 for the product fuel generated through the processing.

For example, in the case where the product fuel shortage of quality QB is only m2, only the information that the product fuel shortage of quality QB is m2 can be regarded as the first shortage. In addition, as another example, in the case where the shortage of the product fuel of quality QB is only m2, in consideration of coping with the shortage being solved by mixing product fuels of different qualities, the shortage in terms of quality of the product fuel that must be added at the time of mixing can be regarded as the first shortage.

Further, as another example, when the amount of shortage of the product fuel of quality QB is only m2, the shortage amount by quality of the acceptable material fuel of the amount m2 or more that can generate the product fuel of quality QB by the processing treatment in the processing treatment facility 50 can be set as the second shortage amount.

That is, the shortage calculation unit 18 performs various calculations as necessary for the amount of fuel (product fuel/acceptable material fuel) that needs to be added to satisfy the demand described in the first order information dO 1.

(step SB6b)

Next, the supplier extracting unit 19 extracts the supplier 2 as the reservation order receiver.

Specifically, for example, when information relating to a delivery date desired by the customer 3 (required delivery date) is described in the first order information dO1 transmitted from the customer terminal 3p, the supplier extraction unit 19 extracts the supplier 2 who can supply fuel to the fuel management base 4 within the supply delivery date that is a deadline within the required delivery date. In addition, it can be set that: when the information on the required delivery date is not described in the first order information dO1, the management server 5 automatically sets the required delivery date in consideration of the actual result of the past transaction with the demander 3.

The "delivery date of supply" can be set to a date set by taking into account a predetermined number of buffer days such as the number of days required for processing in the fuel management base 4 and executing the data in advance of the delivery date of demand specified by the customer 3.

For example, the storage unit 11 stores a list of a plurality of suppliers 2(2A, 2B, 2C, … …) who can reserve orders from the management server 5. More specifically, the supplier information storage area 11c of the storage unit 11 stores: information (transportation time information dD) relating to transportation time required to transport the fuel to the fuel management base 4 from the site of each supplier 2. The supplier extraction unit 19 can extract the supplier 2 that can supply the fuel to the fuel management base 4 during the delivery date of supply, based on the transportation time information dD classified by the supplier 2.

Further, when the insufficient fuel supply is satisfied by the certified fuel transported from the supplier 2, the supplier extracting unit 19 may be configured to: the processing time information dP is read from the processing information storage area 11b of the storage unit 11, and the processing time information dP is considered in addition to the transportation time information dD, and then extracted for the supplier 2 who can supply fuel to the fuel management base 4 in the delivery date.

When this step SB6b is executed, the supplier extraction unit 19 may set: the information (manufacturing capability information dM) relating to the quality of the fuel that can be manufactured by each supplier 2 is read from the supplier information storage area 11c of the storage unit 11, and the suppliers 2 who have difficulty in manufacturing the fuel corresponding to the first shortage amount and/or the second shortage amount determined by the shortage calculation unit 18 in step SB6a are excluded in advance. That is, the supplier extraction unit 19 may be configured to: supply candidates capable of producing fuel corresponding to the first shortage and/or the second shortage determined by the shortage calculation unit 18 in step SB6a are extracted from the plurality of suppliers 2, and then the supplier 2 capable of supplying fuel to the fuel management base 4 during the delivery date is extracted from the extracted supply candidates.

(step SB6c, step SB6d)

When the supplier 2 as the reservation order receiver is extracted by the supplier extraction unit 19 in step SB6b, the supplier reservation order unit 20 creates order information (second order information dO2) for the extracted supplier 2 (step SB6c), and transmits the second order information dO2 to the supplier terminal 2p managed by the target supplier 2 (step SB6 d).

The second subscription information dO2 includes: information relating to the first shortage and/or the second shortage determined by the shortage calculation unit 18, and information relating to the delivery date of supply.

The supplier 2 recognizes the situation of the fuel that has been ordered by the management server 5 by confirming the supplier terminal 2p, and determines whether or not the handling can be coped with. Then, the supplier 2 responds to the management server 5 with an intention of being able to accept the order as necessary.

The management server 5 may be set to: when receiving a reply indicating that the supplier 2 accepts the order, a prompt message indicating that "the scheduled fuel newly transported from the supplier 2 in accordance with the order (order) to the supplier 2 this time is the fuel for coping with the shortage of the order of the customer 3" is transmitted to the in-base terminal 4p as necessary. For example, the presentation information may be set to: the second order information dO2 describing the order content to be delivered to the supplier 2 is associated with the first order information dO1 describing the order content delivered from the target demander 3. By transmitting such a prompt message to the in-base terminal 4p, it is possible to avoid a possible situation in which the fuel (product fuel/acceptance material fuel) newly transported from the supplier 2 for coping with the demand specified by the processing demander 3 is erroneously delivered to another demander 3.

Further, the management server 5 may be set to: when a reply indicating that the supplier 2 to which the second order information dO2 is to be transmitted to the supplier reservation ordering part 20 indicates a rejection of order acceptance is received, the flow returns to step SB6b to cause the supplier extraction part 19 to perform the extraction process of the supplier 2 again. In this case, the supplier extraction unit 19 may be configured to: step SB6b is executed in a state where the supplier 2 who refuses to accept the order is excluded in advance.

Other embodiments

Next, another embodiment will be described.

<1> the management server 5 can be set to: the fuel management base 4 installed in a plurality of places is monitored. In this case, the storage unit 11 stores the stock quantities classified into the fuel management bases 4, and the shipment process instruction creation unit 13 may be configured to: the shipping instruction information d4 is created and transmitted for each fuel management base 4.

The <2> management server 5 may be present in the fuel management base 4 or may be provided outside the fuel management base 4.

<3> the supplier extracting unit 19 may be set to: in step SB6b (see fig. 13), the plurality of suppliers 2 are extracted in consideration of the fuel supplied from the plurality of suppliers 2 that satisfies the supply of the fuel corresponding to the first shortage and/or the second shortage determined by the shortage calculation unit 18.

<4> in the above-mentioned step SA30, there may be a step SA31 (see fig. 14) of processing the acceptance material fuel in advance. For example, as shown in FIG. 2, the fuel management base 4 may have a pre-processing treatment facility 60 for performing this step SA 30.

Fig. 15 is a block diagram schematically showing an example of the configuration of the preprocessing apparatus 60. In the example shown in fig. 15, the preprocessing unit 60 is configured to include a foreign matter removing unit 61, a pulverizing unit 63, a drying unit 64, and a classifying unit 65. When it is difficult to directly perform the designation processing of the acceptance material placement site 32 as the storage destination in step SA30, for example, when the acceptance material fuel transported from the supplier 2 is a non-granular woody biomass fuel and a large amount of foreign matter or uneven size is mixed, the necessary processing is performed on the acceptance material fuel in the preprocessing device 60. Note that the preprocessing unit 60 does not need to have all of the foreign matter removing unit 61, the pulverizing unit 63, the drying unit 64, and the classifying unit 65, but may have at least one unit.

The foreign substance removal apparatus 61 is constituted by the same apparatus as the foreign substance removal apparatus 51 provided in the processing apparatus 50. The foreign substance removal apparatus 51 may double as the foreign substance removal apparatus 61.

The crushing apparatus 63 is constituted by the same apparatus as the crushing apparatus 53 provided in the processing apparatus 50. The crushing apparatus 53 may double as the crushing apparatus 63.

The drying device 64 is configured by the same device as the drying device 54 provided in the processing device 50. The drying device 54 may double as the drying device 64.

The classifying device 65 is constituted by the same device as the classifying device 55 provided in the processing device 50. The classifying device 55 may double as the classifying device 65.

If the fuel management base 4 has the spent clay storage place 61 for receiving the spent clay transported from the spent clay generation place and storing the received spent clay, the woody biomass fuel and the spent clay may be mixed when the processing is performed in step SA 40. Examples of the sites where the spent clay is generated include: production plants for fats and oils such as palm oil, production plants for lubricating oils and petroleum products, and the like.

The spent clay that can be used in combination with the woody biomass fuel is a spent clay containing an oil component, which is produced by subjecting a mineral oil or a vegetable oil to a deodorization treatment or a bleaching treatment with an acid clay or activated clay, and generally has a calorific value of 3000kcal/kg or more. When the woody biomass fuel and the waste clay are mixed, the mixing ratio A to B (mass ratio) of the woody biomass fuel (A) and the waste clay (B) is preferably 98:2 to 84: 16. When the mixing ratio of the spent bleaching earth (B) is less than 2 mass% or more than 16 mass%, the granular woody biomass fuel may not have sufficient mechanical strength.

Note that, as the means for mixing the woody biomass fuel and the waste clay, the mixing means 52 may be configured to be provided with only the stirring blade, but it is preferable to use a means which is provided with an additional stirring blade and is configured to be able to rotate the mixing container itself. By rotating the mixing container itself, it is possible to favorably mix a viscous material such as waste clay and a material having a low volume density such as a woody biomass fuel. An example of a mixer configured to rotate the container itself is an Intensive mixer (intense mixer) manufactured by eirich corporation.
