Description

Logistics method and logistics base for granular wood biomass fuel

Technical Field

The invention relates to a logistics method of granular woody biomass fuel and a logistics base of the granular woody biomass fuel.

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 or quality stabilization.

The present invention has been made in view of the above problems in the logistics of the woody biomass fuel; in particular, the object is to stably supply a granular woody biomass fuel having predetermined quality characteristics to consumers.

Means for solving the problems

The invention relates to a material flow method of granular wood biomass fuel, which is characterized in that,

the logistics method comprises the following steps:

a step (a) of receiving a product fuel or an acceptance material fuel from a fuel production site, the product fuel being a granular woody biomass fuel in a shippable state, the acceptance material fuel being a woody biomass fuel that needs to be processed to produce the product fuel;

a step (b) of specifying the acceptance material fuel received in the step (a) from a plurality of acceptance material placement sites according to the quality of the acceptance material fuelIs stored toAnd storing the acceptance material fuel at the specified acceptance material placement site;

a step (c) of subjecting the acceptance material fuel stored in the acceptance material storage place to a predetermined processing treatment to produce the product fuel;

a step (d) of specifying the product fuel received in the step (a) and the product fuel generated in the step (c) from a plurality of product placement locations according to the quality of the product fuel, and storing the product fuel in the specified product placement locations;

and (e) delivering the product fuel stored in the product storage location to a fuel demand location.

Based on the above method, the fuel inputted from each fuel manufacturing site is received at one place and stored at different storage sites according to quality.

As the fuel to be input from the fuel production site, the following is conceivable: the fuel is a fuel obtained by granulating a fuel of a quality (hereinafter referred to as "shippable quality") that can be directly shipped to a destination; this fuel is not directly deliverable because it does not have a deliverable quality and requires processing. This difference is due to the manufacturing and processing capabilities of the fuel manufacturing site, 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 acceptance material fuel inputted from the fuel manufacturing site is stored in the specified acceptance material placing place according to the quality. Then, the acceptance material fuel is subjected to a predetermined processing treatment to produce a product fuel. In the above method, since the processing can be performed in a facility (hereinafter referred to as a "logistics base") that receives the approved material fuel, even when the fuel input from the fuel production site is of a quality that cannot be directly delivered without being pelletized, for example, the fuel can be converted into a fuel (the product fuel) in a state of a deliverable quality.

Further, according to the above method, the acceptable material fuel is stored in different acceptable material storage places according to the quality, and therefore, the quality of the acceptable material fuel used in the processing can be grasped. The quality of the fuel (product fuel) produced by the processing depends on the quality of the acceptance material fuel used for the processing. Thus, even when the stock of the product fuel of the required quality is insufficient, the acceptance material required for producing the product fuel of the required quality can be easily specified, and the product fuel of the required quality can be produced on site (in a logistics base) by performing processing on the specified acceptance material fuel.

Further, the product fuel produced by processing the acceptable material fuel in this way is stored in different product placement places depending on the quality. Therefore, even in the case where a place of demand has ordered a product fuel (granular woody biomass fuel) of a specific quality (hereinafter referred to as "required quality"), the stock amount of the product fuel in the logistics base that reaches the required quality can be identified in a short time. In addition, even when the stock amount is less than the required amount, since the acceptance material fuel before the processing is stored in the acceptance material storage place and the processing can be performed in the logistics base, the processing can be performed on the acceptance material fuel of the predetermined quality in the logistics base, and the product fuel of the required quality can be generated to satisfy the required amount. As a result, the product fuel, which is processed as needed to satisfy the demand amount and the demand quality, is delivered to the destination.

Note that, as described above, the fuel input from the fuel production site sometimes exhibits a quality satisfying the condition of the product fuel (shippable quality). The fuel may be stored not in the acceptance material storage place but in a specified product storage place according to the quality.

As described above, according to the method for distributing granular woody biomass fuel in accordance with the present invention, since the product fuel is stored in different storage locations depending on the quality, it is possible to efficiently deliver a plurality of granular woody biomass fuels having different qualities and to efficiently distribute the woody biomass fuel by performing the processing on site.

Optionally, the process (e) comprises:

a step (e1) of designating one or more product placement locations storing the product fuel satisfying a quality standard corresponding to a request of a customer; and

a step (e2) of delivering the product fuel stored in the product placement location specified in the step (e1) to the destination.

Alternatively, the predetermined processing treatment in the step (c) may be one or more treatments 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 described above, depending on the fuel input from the fuel production site, there is a case where the fuel is not suitable for shipment as product fuel in terms of quality. With the above method, even with such a fuel, the fuel can be converted into a fuel (product fuel) having a quality that can be shipped by performing processing such as foreign matter removal, mixing, pulverization, drying, classification, and molding.

Optionally, the step (b) includes:

a process (b1) of extracting at least a portion of the acceptance material fuel received in the process (a);

a step (b2) of analyzing the acceptance material fuel extracted in the step (b1) with respect to the calorific value and/or the predetermined chemical composition; and

a step (b3) of specifying the quality of the acceptable material fuel based on the analysis result of the step (b2) and according to the range to which one or more indexes selected from the group consisting of the alkali metal content, chlorine content, water content, and calorific value of the acceptable material fuel belong.

Based on the above method, the quality of the certified material fuel received in the process (a) can be specified at the receiving site (logistics base), and therefore, a placement place of the certified material as a storage destination of the certified material fuel can be easily specified. Note that some fuel production sites can analyze the calorific value and/or the predetermined chemical composition of the input fuel (acceptable material fuel) with a certain degree of accuracy. In this case, when the acceptable material fuel is received in the step (a), the information on the quality may be acquired together, and the acceptable material placement location as the storage destination of the acceptable material fuel may be specified based on the acquired quality information.

Optionally, the process (d) comprises:

a step (d1) of extracting the product fuel received in the step (a) and at least a part of the product fuel produced in the step (c);

a step (d2) of analyzing the calorific value and/or a predetermined chemical composition of the product fuel extracted in the step (d 1); and

and a step (d3) of specifying the quality of the product fuel based on the analysis result of the step (d2) and according to a range to which one or more indexes selected from the group consisting of the alkali metal content, the chlorine content, the water content, and the calorific value of the product fuel belong.

As described above, the fuel input from the fuel production site may contain fuel (product fuel) having a quality that can be delivered. By having the above-described steps (d1) to (d3), the quality of such product fuel can be specified on site (in a logistics base), and therefore, the product placement location as a storage destination can be easily specified.

In addition, even if the quality of the acceptable material fuel for processing can be grasped as the product fuel produced by performing the processing in the step (c), the expected quality may not be obtained depending on the processing mode. By having the above steps (d1) to (d3), the quality of the product fuel produced by the execution of the processing can be specified on site (in the logistics base), and therefore, an appropriate product placement location as a storage destination can be easily specified.

Note that, in the case where the demanded amount ordered in the demanded place exceeds the stock amount and the shortage is compensated by the processing in the step (c), the product fuel generated by the processing may be directly shipped without being stored in the product storage place. In this case, it is sometimes desired to check whether or not the product fuel produced by the processing has a required quality.

To cope with this, optionally,

the step (e) of delivering the fuel to the demand place includes:

a step (e3) of extracting at least a part of the product fuel produced in the step (c);

a step (e4) of analyzing the product fuel extracted in the step (e3) with respect to the calorific value and/or the predetermined chemical composition;

a step (e5) of specifying the quality of the product fuel based on the analysis result of the step (e4) in accordance with the range of one or more indices selected from the group consisting of the alkali metal content, chlorine content, water content, and calorific value of the product fuel; and

a step (e6) of confirming that the quality of the product fuel specified in the step (e5) satisfies a quality standard corresponding to a request of a customer.

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

Additionally, optionally, the method of logistics of particulate woody biomass fuel comprises: a step (f) for receiving the spent bleaching clay; and is

The predetermined processing in the step (c) includes: mixing and molding the spent bleaching earth received in the step (f) with the acceptance material fuel.

Based on the above method, even in the case where the acceptance material fuel which does not reach the shippable quality is input, it is possible to produce a high-quality product fuel having high mechanical strength by performing processing on the acceptance material fuel.

Optionally, the process (a) includes a process of receiving the product fuel or the acceptance material fuel transported by land or sea from the fuel manufacturing site, and

the step (e) includes a step of transporting the product fuel stored in the product placement site to the demand site by land transportation or sea transportation.

In addition, the present invention is a logistics base of granular woody biomass fuel, characterized in that the logistics base comprises:

a delivery device for delivering a product fuel, which is a granular woody biomass fuel in a deliverable state, to a demand place for the fuel;

an article placement site that stores the article fuel according to quality;

a receiving apparatus for receiving an acceptance material fuel from a fuel manufacturing site, the acceptance material fuel being a woody biomass fuel that requires processing to generate the product fuel;

a certified material placement site that stores the certified material fuel by quality; and

a process treatment facility for performing said process treatment on said approved material fuel to thereby produce said article fuel.

It is noted that the receiving apparatus may also receive the manufactured fuel from the fuel manufacturing site.

According to the logistics base of the granular woody biomass fuel having the above configuration, a storage base and a delivery base for stabilizing the supply of the granular woody biomass fuel (product fuel) are realized. The higher the quality of the granular woody biomass fuel, the higher the price, and it is presumed that the quality of the granular woody biomass fuel required in demand differs depending on the use situation of the granular woody biomass fuel utilized in the demand. Therefore, it is preferable to store product fuel of a required quality (required quality) to meet various demands in advance and make it into a shippable form. According to the logistics base described above, the product fuel is stored according to the quality, and therefore, the product fuel of the required quality required to meet the demand can be easily specified.

Even when the stock quantity of the product fuel having the required quality is insufficient relative to the required quantity, the logistics base is provided with processing facilities, so that the acceptance material fuel having a quality lower than the shippable quality can be processed, and the product fuel having the shippable quality and the required quality can be generated in the logistics base, thereby making it possible to supplement the required quantity.

Therefore, seasonal variations in the supply amount of the woody biomass fuel, variations in the supply amount due to logistic problems, and the like can be buffered by the storage capacity of the logistic base in the present invention, and stable supply to demand can be achieved.

Optionally, the logistics base of particulate woody biomass fuel has: 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.

According to this configuration, the quality of each fuel can be specified by analyzing the material fuel and/or the product fuel in the logistics base. This enables the acceptance check material placement location or the product placement location to be designated as a storage destination.

In particular, by providing the logistics base of the granular woody biomass fuel with an analysis device for analyzing the product fuel, it is possible to ship the granular woody biomass fuel while confirming the quality characteristics of the load carried on a transport means such as a ship or a truck, or to ship the granular woody biomass fuel after confirming the quality characteristics of the load, thereby preventing the product fuel from being shipped without reaching a required quality.

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 processing apparatus has:

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.

Optionally, the processing apparatus has:

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.

Optionally, the receiving device has a function of receiving spent bleaching earth, and

the mixing device has a function of mixing the pulverized acceptance material fuel with the spent bleaching earth.

Thus, the granular woody biomass fuel composed of a mixture of woody biomass and waste clay having excellent mechanical strength can also be shipped from the logistics base of the granular woody biomass fuel of the present invention.

Optionally, the logistics base of granular woody biomass fuel has an estuary cargo handling facility disposed at the coast portion, and

the bay cargo handling device constitutes the shipping device and the receiving device.

Thus, for example, woody biomass fuel derived from palm coconut shipped from Malaysia or Indonesia sea can be received in large quantities, and bulk shipment can be performed using ships, thereby reducing logistics costs associated with the woody biomass fuel.

Optionally, the receiving apparatus has a function of receiving the acceptance material fuel transported by a handling vehicle, and

the delivery device has a function of delivering the product fuel to the demand site by a carrier vehicle.

This makes it possible to receive woody biomass, which has been conventionally disposed of in waste incineration facilities or final landfills and has a small amount of production, such as construction waste, and to contribute to the construction of a resource-recycling society and meet the needs of inland areas and small customers.

In the logistics base of the granular woody biomass fuel, the total of the amount of the product fuel that can be stored in the product placement site and the amount of the acceptance material fuel that can be stored in the acceptance material placement site 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 the storage capacity of the woody biomass fuel, it is possible to stock fuel required for several weeks for, for example, a 75MW class biomass power generation boiler.

Effects of the invention

According to the present invention, it is possible to stably supply a granular woody biomass fuel satisfying quality corresponding to the demand of a demand place.

Detailed Description

Hereinafter, an embodiment of a method of feeding a granular woody biomass fuel and a feeding base for the granular woody biomass fuel according to the present invention will be described with reference to the accompanying drawings as appropriate.

Fig. 1 is a block diagram schematically showing the configuration of one embodiment of the material flow base of the granular woody biomass fuel in the present invention. Fig. 2 is a flow chart schematically showing the flow of the treatment of the method of logistics of a granular woody biomass fuel in the present invention.

The logistics base 1 of granular woody biomass fuel (hereinafter, appropriately abbreviated as "logistics base 1") shown in fig. 1 has a receiving facility 3, an acceptance material placing site 4, a processing facility 5, a product placing site 6, and a delivery facility 7. The logistics base 1 shown in fig. 1 is one way to implement the logistics method shown in fig. 2.

Note that in the following description, reference will be made as appropriate to the symbols of the respective steps described in the flowchart shown in fig. 2.

The logistics base 1 has the following functions: the biomass fuel delivered from the fuel production site 40(40a, 40b, 40c, 40d, 40e, … …) is received and stored in the receiving device 3, and the stored biomass fuel is delivered to the demand site 50(50a, 50b, 50c, 50d, 50e, … …) by the delivery device 7. The fuel demand site 50 is assumed to be a site where granular woody biomass fuel is expected to be used, and a biomass power plant is exemplified.

The fuel production site 40 is assumed to be a site for producing a granular woody biomass fuel required by the fuel demand site 50 or a site for producing a biomass fuel constituting a raw material for producing the granular woody biomass fuel. As examples, the fuel production site 40 may list: 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 organic resources 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 ".

That is, the fuel production site 40 corresponds to a site for producing the woody biomass from the palm oil industry, and includes a site having a function of processing the woody biomass into pellets.

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 mechanical Durability (DU) described in the standard "woody pellet quality standard" of japan wood pellet association of general community law or a drop strength described in JIS Z8841 "granulated substance-strength test method", 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 the mechanical strength that the granular woody biomass fuel should have in order to have preferable handling properties.

Step S10 and step S20

As described above, the logistics base 1 receives the fuel shipped from the fuel manufacturing site 40(40a, 40b, 40c, 40d, 40e, … …) in the receiving apparatus 3 (step S10, step S20). Step S20 corresponds to step (a) described above.

The reception device 3 preferably includes a marine reception device 3a and a land reception device 3 b. In fig. 1, the following is shown as an example: the fuel is transported from the fuel production sites (40a, 40b, 40c) to the logistics base 1 by a marine vehicle 91 such as a ship, and the fuel is transported from the fuel production sites (40d, 40e) to the logistics base 1 by a land vehicle 92 represented by a transport vehicle such as a truck.

Preferably, the marine receiving facility 3a 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 3a 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.

Note that a ship dedicated to wood chips (wood chips) or the like as an example of the ship is generally equipped with a crane. In this way, the marine vessel 3a may be provided with a receiving hopper to which a conveyor is attached so as to receive the fuel transported by a cargo ship equipped with a crane.

Thus, for example, when the fuel production site (40a, 40b, 40c) is a production site for fuel from palm coconut such as malaysia or indonesia, a large amount of these woody biomass fuels and the like can be received by the marine vessel as the logistics base 1. Further, by using the marine receiving facility 3a as a marine shipping facility 7a, which will be described later, a large amount of product fuel can be shipped to the fuel demand site 50 by the ship. Thereby, logistics costs associated with woody biomass fuels can be reduced.

The land transportation receiver 3b 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 receiving facility 3 with the land use receiving facility 3b, 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, and which has a small amount of production, by the logistics base 1, and it is possible to contribute to the construction of the resource recycling society. Further, by using the land transportation receiver 3b also as a land transportation delivery device 7b described later, the product fuel can be delivered to a fuel demand place 50 located in an inland area or having a small demand amount.

However, the receiving equipment 3 provided in the logistics base 1 may be provided with only one of the marine receiving equipment 3a and the land receiving equipment 3 b.

Here, as the fuel transported from the fuel manufacturing site 40, the following is conceivable: the fuel is a fuel (product fuel) granulated in a state having a quality (shippable quality) that can be directly shipped to a destination; 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, etc., of the fuel manufacturing site 40.

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 such as chips, spiral chips (Screw cutlingchip), chips (chip) and chips; 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 S40 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 logistics base 1 has an acceptance material placing place 4 and an article placing place 6. The receiving material placing place 4 is a place where the receiving material fuel is stored, and the product placing place 6 is a place where the product fuel is stored. That is, in the case where fuel (product fuel) having a quality that can be shipped is transported from the fuel production site 40 to the logistics base 1, the fuel is stored in the product placement site 6. On the other hand, in the case where fuel (approved material fuel) that does not reach the shippable quality is transported from the fuel manufacturing site 40 to the logistics base 1, the fuel is stored in the approved material placement site 4.

The logistics base 1 has a plurality of acceptance material placing sites 4(4a, 4b, … …). In these acceptable material storage locations 4, the acceptable material fuel to be stored differs in quality. That is, one of the acceptable material storage locations 4a corresponds to a storage location for acceptable material fuel having a quality level Qa, and the other acceptable material storage location 4b corresponds to a storage location for acceptable material fuel having a quality level Qb.

Step S30

After the logistics base 1 receives the acceptance material fuel from the fuel manufacturing site 40, the acceptance material placement site 4 to be stored is specified according to the quality of the acceptance material fuel, and the acceptance material fuel is transported and stored at the specified acceptance material placement site 4 (step S30). Step S30 corresponds to step (b).

Fig. 3 is a flowchart showing an example of the flow of the processing included in step S30. In the example shown in fig. 3, step S30 includes the processes of step S32, step S33, step S34, step S35, and step S36.

First, a part of the approved material fuel is extracted from a large amount of approved material fuel transported from a fuel manufacturing site (step S32). For example, as shown in fig. 1, the logistics base 1 may be provided with a sampler 12 for acceptance material fuel for performing step S32. The sampler 12 for acceptance 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. This step S32 corresponds to step (b 1).

Next, the extracted acceptance material fuel is analyzed (step S33). For example, as shown in fig. 1, the logistics base 1 may be provided with an analysis apparatus 11 for performing step S33.

The analyzer 11 is not particularly limited as long as it can cope with a desired test and analysis item, and a general-purpose test device or analysis device can be used. The analysis device 11 may be configured to be unmanned by a robot operation automation system or the like. As an example, the analyzing device 11 has a function of testing and analyzing the alkali metal content, chlorine content, water 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 JIS Z7302-6 "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 analysis device 11 does not necessarily have all of the analysis 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 analysis functions.

Note that, as a method of transporting the acceptance material fuel extracted by the sampler 12 for acceptance material fuel to the installation site of the analysis device 11, there is no particular limitation, and a pneumatic transport pipe system or the like capable of automatically transporting a sample is preferably used.

Next, based on the result of the analysis performed by the analysis apparatus 11, the quality of the acceptance material fuel as the object is specified (step S34). Step S34 corresponds to step (b 3).

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 sizes and 12 types (2 × 2 × 3) as a whole, in consideration of the difficulty in the processing performed in step S40 described later. The classified items may also include chlorine content.

Next, based on the quality of the certified material fuel specified in step S34, a certified material placement location 4 as a storage destination of the certified material fuel is selectively specified from among the respective certified material placement locations (4a, 4b … …) (step S35). As described above, the quality of the acceptable material fuel to be stored differs in each acceptable material storage location 4. The information on the quality of the acceptable material fuel distributed to each acceptable material placement site 4 may be stored in advance on a storage section or a paper surface of an information processing apparatus not shown in the drawings. An acceptance material placement site 4 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 S34 reaches the shippable quality, the acceptable material fuel may be stored in a predetermined product placement location 6, or one placement location (for example, the acceptable material placement location 4a) of the acceptable material placement locations 4 may be used as the product placement location 6.

Then, the acceptance material fuel is transported to the specified acceptance material placement site 4 and stored (step S36). Note that, when transporting fuel (acceptance material fuel/product fuel) in the logistics base 1, for example, when transporting the acceptance material fuel from the receiving facility 3 to the acceptance material placement site 4, 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. Since chips and the like easily cause a clogging state called Bridging (Bridging), it is preferable to take measures for preventing clogging such as a baffle in advance in a place having a narrow path.

Note that the acceptance material placement site 4(4a, 4b, … …) is not particularly limited as long as it can store the received acceptance material fuel, which is woody biomass fuel, without causing it to be wet by rain or the like, and can smoothly carry out receiving and loading, and can effectively utilize a roofed building or silo (such as a silage tower). 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 4, 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.

Note that, depending on the fuel production site 40, there may be a case where the fuel production site 40 has a function of analyzing the quality of the fuel (acceptable material fuel or product fuel) delivered to the logistics base 1, and in this case, the fuel production site 40 may notify the logistics base 1 of information relating to the quality of the fuel being transported. In this case, it is possible to specify the acceptance material placement site 4 as the storage destination of the acceptance material fuel based on the information on the quality of the acceptance material fuel notified from the fuel manufacturing site 40, and store the acceptance material fuel in the specified acceptance material placement site 4 (steps S35, S36). In this case, the analysis of the material fuel to be tested may not be performed in the base 1.

Step S40

Next, processing is performed on the acceptance material fuel stored in the acceptance material placement site 4, and quality improvement processing is performed, thereby producing fuel (product fuel) of a quality that can be delivered. Step S40 corresponds to step (c). As shown in fig. 1, the logistics base 1 includes processing equipment 5 for executing step S40.

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. Note that, in step S40, all of these processes may be executed, or only a part of them may be executed.

Fig. 4 is a block diagram schematically showing an example of the configuration of the processing facility 5. In the example shown in fig. 4, the processing facility 5 includes a foreign matter removal facility 51, a mixing facility 52, a crushing facility 53, a drying facility 54, a classifying facility 55, and a molding facility 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 3 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 apparatus 56 is generally composed of a die having a plurality of cylindrical small holes and a compression roller, and the pulverized chips and the like are pressed into the small holes by the compression roller to be formed into granules. 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 fuel production site 40 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, it is conceivable that the granular woody biomass fuel transported from the fuel manufacturing site 40 is not a product fuel but is regarded as an approved 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 process in the present step S40. 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.

As shown in fig. 5, in the case where the logistics base 1 has a spent clay storage place 61 for receiving spent clay transported from the spent clay generation site 60(60a, 60b, … …) and storing the received spent clay, the woody biomass fuel and the spent clay may be mixed in the mixing process included in step S40. Examples of the spent clay generation site 60 include: production plants for fats and oils such as palm oil, production plants for lubricating oils and petroleum products, and the like. In this case, the method for logistics of the granular woody biomass fuel of the present invention includes the step S70 of storing the spent bleaching earth transported from the spent bleaching earth producing site 60. Step S70 corresponds to step (f).

In more detail, as shown in fig. 6, step S70 includes: the step S71 of shipping the spent clay from the spent clay producing site 60, the step S72 of receiving the spent clay at the logistics base 1, and the step S73 of storing the received spent clay in the spent clay storage place 61.

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.

Step S50

Next, with respect to the produced fuel generated in step S40 and the produced fuel received in step S20, the production placement site 6 as a storage destination is specified in accordance with the quality, and the produced fuel is transported and stored at the specified production placement site 6 (step S50). Step S50 corresponds to step (d).

Fig. 7 is a flowchart showing an example of the flow of the processing in step S50. In the example shown in fig. 7, step S50 includes the processes of step S52, step S53, step S54, step S55, and step S56.

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 S52). This step S52 corresponds to step (d 1).

For example, as shown in fig. 1, the logistics base 1 may be provided with a sampler 13 for product fuel for performing step S52. The product fuel sampler 13 may be configured in the same manner as the above-described acceptance material fuel sampler 12. Note that the sampler 12 for acceptance material fuel may double as the sampler 13 for product fuel.

Next, the extracted product fuel is analyzed (step S53). This step S53 corresponds to step (d 2). In the example shown in fig. 1, the following is shown: the product fuel extracted by the sampler 13 for product fuel is analyzed by the same analyzing apparatus 11 as that of step S33. The logistics base 1 may be provided with a dedicated analysis facility 11 for executing the processing in step S53, which is different from the analysis facility 11 used in step S33.

In step S53, 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 S33. However, in the case of the product fuel produced through the processing in step S40, 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 S53, for example, only two items of the calorific value and the alkali metal content may be analyzed without analyzing the water content.

Next, based on the result of the analysis performed by the analysis device 11, the quality of the target product fuel is specified (step S54). Step S54 corresponds to step (d 3).

As a method of 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 of specifying the quality of the acceptable material fuel described in step S34. 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 S54, the product placement location 6 as the storage destination of the product fuel is selectively specified from among the product placement locations (6a, 6b, … …) (step S55). As described above, the quality of the product fuel to be stored differs in each product placement site 6. The information on the quality of the product fuel distributed to each product placement site 6 may be stored in advance on a storage section or a paper surface of an information processing device not shown in the drawings. The product placement site 6 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 6 and stored (step S56). The product placement site 6(6a, 6b, … …) is not particularly limited as long as it can store the received woody biomass fuel, i.e., the approved material fuel, without causing it to be wet by rain, and can smoothly receive and load the received woody biomass fuel, similarly to the approved material placement site 4(4a, 4b, … …), and can effectively utilize a building with a roof or a silo (such as a silo tower).

Step S60

Then, the product fuel stored in the product placement site 6 is delivered to the fuel demand site 50(50a, 50b, 50c, … …). Step S60 corresponds to step (e).

Fig. 8 is a flowchart showing an example of the flow of the processing included in step S60. In the example shown in fig. 8, step S60 includes the processing of step S61, step S62, step S63, step S64, step S65, and step S66.

Information relating to the quality required (required quality) of each fuel demand site 50 is provided from each fuel demand site 50(50a, 50b, 50c, … …). In the logistics base 1, the product placement site 6 storing the product fuel having the required quality is first designated (step S61). This step S61 corresponds to step (e 1).

Next, a part of the product fuel is extracted from the large amount of product fuel stored in the designated product placing place 6 (step S62). This step S62 corresponds to step (e 3).

For example, as shown in fig. 1, the logistics base 1 may be provided with a sampler 14 for a shipment for executing step S62. The sampler 14 for the shipment product can be configured in the same manner as the above-described sampler 12 for the acceptance material fuel or the sampler 13 for the product fuel. Note that the sampler 12 for acceptance material fuel and/or the sampler 13 for product fuel may also double as the sampler 14 for product.

Next, the extracted product fuel is analyzed (step S63). This step S53 corresponds to step (e 4). In the example shown in fig. 1, the case where the product fuel extracted in the sampler 14 for shipment is analyzed by the same analyzing device 11 as that in step S33 is shown. Here, the logistics base 1 may be provided with a dedicated analysis facility 11 for execution in step S63, which is different from the analysis facility 11 used in step S33 and/or step S53.

Next, based on the result of the analysis performed by the analyzing device 11, the quality of the product fuel extracted by the sampler 14 for the shipment item is specified, and it is confirmed whether or not the specified quality reaches the required quality (step S64). The step S64 corresponds to the step (e4) and the step (e 5). If the target product fuel does not reach the required quality, the process may return to step S61 to re-specify another product placement site 6 where the target product fuel is stored, or return to step S40 to process the acceptance material fuel to produce the product fuel reaching the required quality.

In step S64, if it is confirmed that the target product fuel has reached the required quality, a large amount of the product fuel stored in the product storage location 6 is transported to the delivery device 7 (step S65).

The shipping device 7 preferably includes a marine shipping device 5a and a land shipping device 5 b. The shipping facility for marine use 5a 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 facility 5b is not particularly limited as long as it can be shipped according to the packaging method, such as a hopper for loading bulk trucks and a forklift for handling bulk bags.

The shipping facility 7 included in the logistics base 1 may include only one of the marine shipping facility 5a and the land shipping facility 5 b.

The product fuel is shipped from the marine delivery facility 5a to the fuel-demand sites 50(50a, 50b, 50c) by a marine vehicle 93 such as a ship, and shipped from the land delivery facility 5b to the fuel-demand sites 50(50d, 50e) by a land vehicle 94 represented by a transport vehicle such as a truck (step S66). This step S66 corresponds to step (e 2).

Note that, as long as the wetting with water or the like does not occur, the properties of the granular woody biomass fuel are considered to be hardly deteriorated during storage. When the product placement location 6 as the storage destination is determined in step S50 as the product fuel stored in the product placement location 6, the quality thereof is analyzed and specified. Therefore, the product fuel stored in the product placement site 6 will, in most cases, continuously ensure quality corresponding to the product placement site 6 in which the product fuel is stored even at the time of shipment. From this viewpoint, steps S62 and S63 may be omitted, and in step S64, it is only checked whether or not the quality of the product fuel associated with the product placement site 6 as the storage destination reaches the required quality.

Note that, in the above step S30, there may be step S31 (see fig. 9) of processing the acceptance material fuel in advance. For example, as shown in fig. 1, the logistics base 1 may be provided with a preprocessing processing device 8 for performing the step S30.

Fig. 10 is a block diagram schematically showing an example of the configuration of the preprocessing apparatus 8. In the example shown in fig. 10, the preprocessing unit 8 includes a foreign matter removing unit 81, a pulverizing unit 83, a drying unit 84, and a classifying unit 85. When it is difficult to directly perform the designation processing of the acceptance material placement site 4 as the storage destination in step S30, for example, when the acceptance material fuel transported from the fuel manufacturing site 40 is a non-granular woody biomass fuel and a large amount of foreign matter or size unevenness is mixed, necessary processing is performed on the acceptance material fuel in the preprocessing device 8. Note that the preprocessing unit 8 does not need to include all of the foreign matter removing unit 81, the pulverizing unit 83, the drying unit 84, and the classifying unit 85, and may include at least one of them.

The foreign substance removal device 81 is configured by the same device as the foreign substance removal device 51 provided in the processing device 5. The foreign substance removal apparatus 51 may double as the foreign substance removal apparatus 81.

The mill 83 is configured by the same mill 53 as the processing facility 5. The crushing apparatus 53 may double as the crushing apparatus 83.

The drying device 84 is configured by the same device as the drying device 54 provided in the processing device 5. The drying device 54 may double as the drying device 84.

The classifying device 85 is configured by the same device as the classifying device 55 provided in the processing device 5. The classifying device 55 can double as the classifying device 85.

The total of the amount of the acceptable material fuel that can be stored in the acceptable material storage locations 4(4a, 4b, 4c, … …) and the amount of the product fuel that can be stored in the product storage locations 6(6a, 6b, 6c, … …) in the logistics base 1 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 logistics base 1 with such storage capacity, it is possible to stock, for example, fuel required for a 75MW class biomass power generation boiler for several weeks.
