Description

  The present invention relates to a biomass fuel distribution method including palm coconut shells, and a distribution base for carrying out the method.

  Due to the enforcement of the Act on Special Measures for Renewable Energy, biomass such as tree trunks and branches, cutting chips, bark chips, sawdust, bark, building waste, etc., which are renewable energies, are used in power generation boilers and cement clinker firing equipment. Technology development for use as an alternative fuel is underway. In particular, from the viewpoint of quantity stability and calorific value, the use of biomass derived from the palm oil industry in Malaysia and Indonesia is being actively promoted.

  Palm Kernel Shell (hereinafter sometimes referred to as “PKS”) is generated as a by-product of the palm oil industry over 10 million tons per year and has a high calorific value of over 4000 Kcal / kg. In addition, since it has desirable characteristics as a renewable resource that the amount of ash when baked is small, it is actively used as a biomass fuel.

  On the other hand, since PKS contains a large amount of various fatty acids including lower fatty acids such as caprylic acid and capric acid, countermeasures for odor are required when handling PKS in large quantities. For example, Patent Literature 1 listed below discloses a method for storing palm coconut seed shells that is stored after heat treatment at a temperature of 80 ° C. or higher using extracted steam generated from a power generation facility. . Patent Document 2 below includes a heat treatment step at 115 ° C. or higher, and adjusts the total moisture content of the palm palm seed shell to 7 to 15% by mass, and further adjusts the oil content to 10 mg or less per gram of PKS. Is disclosed.

JP 2016-43335 A Japanese Patent Laid-Open No. 2006-93790

  However, the method disclosed in Patent Document 1 or Patent Document 2 requires a heat source in a storage place, a processing place, or the like for deodorizing PKS, and uses PKS for biomass fuel. There will be restrictions on the above. Moreover, it is not a fundamental countermeasure technique for stably supplying PKS to consumers.

  The present invention has been made in view of problems in logistics of PKS including the problem of odor. In particular, the present invention can stably supply biomass fuel including palm coconut shells having predetermined quality characteristics to consumers. It aims to provide a possible method. In addition, the present invention is a distribution base for realizing such a method (hereinafter referred to as “distribution base”), and suppresses the generation of unpleasant odor of PKS so that it can be installed in the suburbs of demand areas. The purpose is to provide a logistics base with functions.

  In the present invention, the biomass fuel containing palm coconut shell (PKS) refers to a woody biomass fuel containing 50% by mass or more of PKS, which is a woody biomass derived from the palm oil industry. In this biomass fuel containing PKS, as a mixture other than PKS, for example, PKS such as palm trunk (Oil Palm Trunk, OPT), foliage (Oil Palm Fronds, OPF), empty fruit bunch (Empty Fruit Bunch, EFB), etc. Examples include woody biomass derived from the palm oil industry, and wood chips or wood pellets of tree species other than palm palm mixed with PKS as a method of deodorization in the biomass fuel logistics method of the present invention as described later. .

The present invention is a biomass fuel distribution method including palm coconut shell,
(A) receiving from a supplier a pre-processing fuel that is a biomass fuel containing palm coconut shell, which is a raw material of a product fuel that is a biomass fuel containing palm coconut shell that can be shipped;
(B) removing the fiber portion of the palm coconut shell by subjecting the pre-processed fuel received in the step (a) to a separation treatment;
Step (c) for determining whether the biomass fuel obtained in the step (b) is an incoming product fuel that shows an odor higher than a shippable odor or the product fuel that shows an odor within the shippable odor. When,
A step (d) of generating the product fuel by performing a predetermined deodorization treatment on the received product fuel;
Identifying the storage location of the product fuel from a plurality of product storage locations according to the quality of the product fuel, and storing the product fuel in the specified product storage location (e),
It has a step (f) of shipping the product fuel stored in the product storage area to a shipping destination.

  According to the above method, biomass fuel (hereinafter referred to as “pre-processing fuel”) containing palm coconut shell (PKS) that is carried in with various degrees of odor is received at one place, and odor is also received. After being deodorized by applying an appropriate treatment according to the strength of the fuel, it is stored in different storage locations depending on the quality as fuel. The “pre-processing fuel” here refers to a biomass fuel containing PKS in a state before removing the fiber portion of the palm coconut shell.

  For example, Tenera varieties that have been cultivated to reduce the percentage of endocarp (Endocarp) in the palm palm fruit and increase the percentage of mesocarp to increase the yield of palm oil (main production areas) (Malaysia) has a strong odor, whereas Dura (the main place of production is Indonesia), which has a relatively large proportion of endocarp in the fruit and a small proportion of mesocarp, is said to have a weak odor compared to Tenera. . In addition, since the pre-processing fuel generates self-heating due to oil oxidation or the like, the temperature in the hold at sea is about 90 ° C. If the temperature environment is around 90 ° C., it is possible to inactivate miscellaneous bacteria that cause odors, but if the humidity in the hold is high, the inactivation of such bacteria becomes insufficient.

  In the step (a), the pre-processed fuel carried in from palm coconut shell supply sites such as Malaysia and Indonesia and other biomass fuel distribution bases is first subjected to separation processing in the step (b). By this separation process, PKS contained in the pre-process fuel is separated into a shell portion having a weak odor intensity and a beard-like fiber portion having a strong odor intensity.

  Biomass fuel containing PKS consisting of separated PKS shells (hereinafter sometimes referred to as “PKS fuel”) has an odor that can be shipped directly to consumers (hereinafter referred to as “shippable odor”). .) And those that do not satisfy the shippable odor and cannot be shipped as they are, and require deodorizing treatment. Such a difference in odor intensity is caused by the variety of palm palm that produced PKS as a by-product, the temperature and humidity conditions of the storage environment in which the pre-processing fuel has passed by the receiving step (a), and the like. In the present specification, among the PKS fuels after the step (b), the fuel that shows an odor within the odor that can be shipped like the former is called “product fuel”, and the odor that is higher than the odor that can be shipped like the latter This fuel is referred to as “received fuel”.

  The PKS fuel from which the fiber part has been separated (removed) is judged whether it is an incoming product fuel or a product fuel according to the level of odor in step (c).

  The PKS fuel determined as the received fuel in the step (c) is subjected to a predetermined deodorizing process in the step (d), and becomes a product fuel exhibiting an odor within a shippable odor. As described above, according to the logistics method of the present invention, the deodorizing process can be performed in the base (distribution base) having the function of receiving and storing the pre-processing fuel, so that the supply source such as palm coconut shell supply place Even if the PKS fuel in which the fiber part is separated from the pre-processed fuel that has been carried in from the factory does not satisfy the odor that can be shipped, the odor is suppressed to a level that can be shipped (product fuel) ).

  Note that the step (d) is not limited to the PKS fuel determined as the received product fuel in the step (c), and the fiber part has already been removed at the time of acceptance in the step (a), and more than the odor that can be shipped. A PKS fuel that has been known in advance to have a high odor, that is, a received product fuel may also be executed.

  The product fuel is stored in a storage location (product storage) according to quality in the step (e). For this reason, even when a product fuel of a specific quality (hereinafter referred to as “required quality”) is ordered from the consumer side, the stock quantity in the distribution base of the product fuel that satisfies the required quality is It is possible to recognize in a short time. And even if the inventory amount is below the demand amount, the received product fuel before deodorization processing is stored in the receiving product storage area, and the deodorization processing is performed in the distribution base as described above. Since the product fuel can be generated, the demand can be covered by this. As described above, the received fuel is deodorized as necessary, and then the product fuel is shipped to the shipping destination (step (f)).

In addition, the product fuel to be stored in the product storage place in the step (e) may include any one of the following (i) to (iii).
(I) PKS fuel determined to be product fuel in step (c);
(Ii) PKS fuel converted into product fuel as a result of the deodorization process in step (d);
(Iii) A PKS fuel in which the fiber part has already been removed at the time of acceptance in step (a) and the odor is within the odor that can be shipped, that is, the product fuel can be grasped in advance.

  As described above, according to the physical distribution method of the present invention, a deodorizing process is performed as necessary in a base where fuel is received and stored. Therefore, a place where odor problems are likely to occur, for example, in the suburbs of urban areas. Even so, the fuel can be stored. Further, it is possible to classify the PKS fuel into the product fuel and the received product fuel according to the level of the odor in advance and perform the deodorizing process only on the PKS fuel determined as the received product fuel. Thereby, a large-scale installation becomes unnecessary as an installation for realizing deodorization processing.

  Therefore, according to the physical distribution method of the present invention, it is possible to flexibly construct a physical distribution base (distribution base) for PKS fuel, and promote the use of PKS.

  In addition, the fiber part of PKS separated in the said process (b) is not contained in the product fuel in the physical distribution method of this invention. This PKS fiber part is used as it is after being subjected to deodorizing treatment by heating or the like in a facility different from the distribution base of the present invention, or used as a binder for pelletized biomass fuel, etc. You can use it as

  In the step (d), the predetermined deodorization treatment includes mixing treatment with wood chips or wood pellets of tree species other than palm coconut, deodorant spraying treatment, and ambient temperature air ventilation treatment for the received fuel. It may be one or more processes selected from. As wood chips or wood pellets of tree species other than palm palm, wood chips or wood pellets having a deodorizing effect such as cedar, cypress, larch, red pine, and cherry can be employed.

  According to the above method, without using a separate heat source, the received fuel that exhibits an odor higher than the odor that can be shipped is subjected to a deodorization process to produce a product fuel that exhibits an odor within the odor that can be shipped. Therefore, a large facility is not required to perform the deodorizing process.

The step (f)
A step (f1) of identifying one or more product storage locations where the product fuel that satisfies the quality standards according to the request of the shipping destination is stored;
There may be a step (f2) of shipping the product fuel stored in the product storage area specified in the step (f1) to the shipping destination.

  In order to respond to orders from consumers, the product fuel determined in step (c), the product fuel generated through the deodorization process in step (d), or the product fuel received in step (a) In some cases, it is desirable to ship the product fuel as it is without storing it in the product yard. At this time, there is a case where it is desired to confirm whether or not the product fuel to be shipped satisfies the quality required by the customer.

For such cases,
The step (f)
Extracting at least a portion of the product fuel (f3);
A step (f4) of analyzing the calorific value and / or a predetermined chemical component for the product fuel extracted in the step (f3);
Based on the analysis result of the step (f4), the product fuel is classified according to a range to which one or more indicators selected from the group consisting of the content of alkali metal, content of chlorine, content of water and calorific value of the product fuel belong. Identifying the quality of the fuel (f5);
A step (f6) for confirming that the quality of the product fuel specified in the step (f5) satisfies the quality standard according to the request of the shipping destination may be included.

  By the way, as described above, the product fuel is stored in different product storage places depending on the quality. For this reason, it is assumed that the product fuel stored in each product site satisfies the quality assumed by the product site. Therefore, it is normally expected that the quality required by the customer will be satisfied by shipping the product fuel stored in the product storage area corresponding to the quality that satisfies the quality required by the customer. However, even if the product fuel is taken out from the product yard and shipped, there is a possibility that the quality may change due to moisture absorption during the storage period. It is also assumed that you want to make sure that you meet the requirements.

For such cases,
The step (f)
A step (f1) of identifying one or more product storage locations where the product fuel that satisfies the quality standards according to the request of the shipping destination is stored;
A step (f2) of shipping the product fuel stored in the product storage area specified in the step (f1) to the shipping destination;
Including the steps (f3) to (f6) described above,
The step (f3) may include a step of extracting at least a part of the product fuel stored in the product storage area specified in the step (f1).

In addition, the step (c)
A step (c1) of extracting at least a part of the biomass fuel obtained in the step (b);
A step (c2) of performing odor measurement on the biomass fuel extracted in the step (c1);
Based on the range to which the measurement result of the step (c2) belongs, it may have a step (c3) for specifying whether or not the odor indicated by the biomass fuel is within the shippable odor.

  The step (c2) can be a step of measuring the odor of the extracted biomass fuel (PKS fuel) using, for example, an odor measuring facility such as an odor sensor.

  Further, in the step (c), when the odor indicated by the biomass fuel in the step (c3) exceeds the shippable odor, it is determined that the biomass fuel is the received product fuel, May have a step (c4) of storing in a separate receiving place. In this case, the step (d) relating to the deodorization process may be performed on the received product fuel stored in the received product storage area.

The step (e)
Extracting at least a portion of the product fuel (e1);
A step (e2) of analyzing the calorific value and / or a predetermined chemical component for the product fuel extracted in the step (e1);
Based on the analysis result of the step (e2), the product fuel is classified according to a range to which one or more indicators selected from the group consisting of an alkali metal content, a chlorine content, a moisture content, and a calorific value of the product fuel belong. A step (e3) for specifying the quality of the fuel may be included.

The step (a) includes receiving the pre-processed fuel transported by land or sea from the supplier,
The step (f) may include a step of transporting the product fuel to the shipping destination by land transportation or sea transportation.

  In this case, the supply source is a palm coconut shell supply place, or a first distribution base different from the distribution base that receives the pre-processing fuel in the step (a), and the shipping destination is a biomass fuel demand place, or the The second distribution base may be different from the distribution base.

The present invention is a biomass fuel logistics base containing palm coconut shells,
Shipping equipment for shipping product fuel, which is a biomass fuel containing palm palm shell that can be shipped, to a shipping destination;
A receiving facility for receiving a pre-processing fuel, which is a biomass fuel containing palm coconut shell, as a raw material of the product fuel, from a supplier;
Separation equipment for removing the fiber part of palm coconut shell from the pre-processing fuel;
An odor measuring facility for measuring the odor of biomass fuel including palm coconut shell from which the fiber part has been removed from the pre-processed fuel by the separation facility;
The biomass fuel is a biomass fuel that exhibits a higher odor than the shippable odor measured by the odor measuring facility, the received fuel is subjected to a predetermined deodorization treatment, and the odor within the shippable odor is exhibited. Deodorization equipment for producing product fuel;
The odor measured by the odor measuring equipment is an odor within the shipmentable odor, or the product fuel that is suppressed to the odor within the shipmentable odor by performing the deodorization treatment is stored according to quality. And a product storage area.

  According to the biomass fuel distribution base including the palm coconut shell having the above-described configuration, a storage base and a shipping base for stabilizing the supply of the biomass fuel including PKS is realized. The quality of the biomass fuel required by the consumer is expected to vary depending on the usage situation of the consumer on the premise that the odor is sufficiently suppressed. For this reason, it is desirable to store and be able to ship product fuel that satisfies various required qualities from a plurality of consumers. According to the distribution base of biomass fuel containing palm coconut shell of the present invention, the fuel (product fuel) in a state in which the odor is suppressed is stored according to quality, so that the product fuel satisfying the quality required by the consumer It is easy to specify.

  In addition, if the amount of product fuel stock that satisfies the quality required by the customer is insufficient with respect to the demand amount, for example, product fuel can be generated by deodorizing the received fuel. By cooperating with a plurality of nearby logistics bases, it is possible to secure a predetermined amount of product fuel that satisfies the required quality, thereby meeting the demand.

  The distribution base may have a receiving goods storage place for storing the receiving goods fuel separately from the product storage place. In this case, the total of the amount of the product fuel that can be stored in the product storage area and the amount of the received fuel that can be stored in the reception area is preferably 5,000 t or more, and preferably 10,000 t or more. It is more preferable that it is 20,000 t or more. The required fuel for several days in a 75 MW class biomass power generation boiler can be stocked, for example, by the storage capacity of biomass fuel including palm coconut shells.

  The odor measuring equipment may be equipment capable of continuous measurement.

  Since the biomass fuel distribution base including the palm coconut shell of the present invention has an odor measuring facility, the strength of the odor generated by the PKS fuel can be specified in real time after the PKS fiber portion is removed from the pre-processing fuel. Thereby, the storage place of the PKS fuel after removing the fiber part of the palm coconut shell can be appropriately specified between the product place and the received place. In particular, when large quantities of incoming lots are received, as described above, the odor intensity of PKS fuel differs depending on the storage location in the hold, so the odor intensity varies even with PKS fuel in the same receiving lot. Therefore, it is desirable that the odor intensity of the loaded PKS fuel can be continuously measured.

  The deodorization treatment facility is a mixing facility that mixes wood chips or wood pellets made of tree species other than palm palm to the received fuel, a spraying facility that sprays a deodorant to the received fuel, the receiving Any one or more of venting equipment for venting normal temperature air to the product fuel may be provided.

  According to these deodorization processing facilities, the received fuel that does not satisfy the shippable odor can be converted into the product fuel that satisfies the shippable odor without having a separate heat source.

  The biomass fuel distribution base including the palm coconut shell may have an analysis facility for analyzing the calorific value and / or a predetermined chemical component of the product fuel.

  According to such a configuration, the product fuel can be analyzed in the distribution base, and the quality of each product fuel can be specified. This makes it possible to appropriately specify the product storage location where the product fuel is stored. Furthermore, the biomass fuel distribution base including the palm coconut shell of the present invention is equipped with the analysis equipment, so that the quality of the product fuel stored in the product storage area, that is, the cargo to be shipped to the transportation means such as a ship or a truck. Or after confirming the quality of the cargo, it is possible to prevent the shipment of product fuel that does not satisfy the quality required by the consumer.

  The analysis equipment for analyzing the product fuel transported to the product yard and the analysis equipment for analyzing the product fuel stored in the product yard may be common equipment, respectively. It does not matter as a separate facility.

  The receiving facility may have a function of receiving a wood chip or a wood pellet of a tree species other than palm palm, and the receiving place is a function of storing a wood chip or wood pellet of a tree species other than palm palm. It does not matter even if it has.

  This makes it possible to mix wood chips or wood pellets of tree species other than palm palm with the received fuel at the logistics base, and the PKS fuel has a odor higher than the odor that can be shipped. In addition, it is possible to suppress odors that can be shipped.

  The biomass fuel distribution base including the palm coconut shell may have a harbor handling facility installed on the coast, and the harbor handling facility may constitute the shipping facility and the receiving facility.

The receiving facility has a function of receiving the pre-process fuel, the received product fuel, or the product fuel transported from the palm coconut shell supply site or the first distribution base as the supply source by a ship or a transport vehicle. And
The shipping facility has a function of shipping the pre-processing fuel, the received fuel, or the product fuel to a biomass fuel demand area or a second distribution base as a shipping destination by a ship or a transport vehicle. It does not matter.

  This makes it possible to load the product fuel stored in other adjacent logistics bases when it is not possible to meet the order quantity from the customer at one logistics base. Can be supplied.

  According to the present invention, an unpleasant odor is suppressed, and a biomass fuel containing palm coconut shell having an appropriate quality can be stably supplied.

It is a block diagram which shows typically the structure of one Embodiment of the distribution base of the biomass fuel containing the palm coconut shell which concerns on this invention. It is a flowchart which shows typically the flow of a process of the distribution method of the biomass fuel containing the palm coconut shell concerning this invention. It is a flowchart which shows an example of the flow of the process included in step S40 in FIG. It is a block diagram which shows typically an example of a structure of a deodorizing processing equipment. It is a flowchart which shows an example of the flow of the process included in step S60 in FIG. It is a flowchart which shows an example of the flow of the process included in step S70 in FIG.

  Embodiments of a biomass fuel distribution method including palm coconut shells and a biomass fuel distribution base including palm coconut shells according to the present invention will be described with reference to the drawings as appropriate. Hereinafter, these may be simply referred to as “distribution method” and “distribution base”, respectively.

  FIG. 1 is a block diagram schematically showing the configuration of an embodiment of a distribution base according to the present invention. FIG. 2 is a flowchart schematically showing the flow of processing of the physical distribution method according to the present invention.

  A logistics base 1 shown in FIG. 1 includes a receiving facility 3, a separation facility 4, an odor measuring facility 5, a receiving product storage place 6, a deodorizing treatment equipment 7, a product storage place 8, and a shipping equipment 9. The logistics base 1 shown in FIG. 1 is one mode for carrying out the logistics method shown in FIG.

  In the following description, reference numerals of steps described in the flowchart shown in FIG.

  The distribution base 1 has a function of receiving and storing the pre-process fuel or PKS fuel conveyed from the supply source in the receiving facility 3 and shipping the stored PKS fuel from the shipping facility 9 to the shipping destination. Here, as described above, the PKS fuel is classified into a product fuel and a received fuel. Product fuel is a biomass fuel containing palm coconut shell (PKS), which has a odor controlled within the odor that can be shipped and can be shipped, and the received fuel is an odor that can be shipped. Refers to things that exceed. In addition, the pre-processing fuel refers to a biomass fuel containing PKS having a fiber part, which is a raw material of PKS fuel and has been conveyed from a supply source.

  As will be described later, the fuel before processing has a beard-like fiber portion having a strong odor, and processing for removing the fiber portion from the fuel before processing is performed in the distribution base 1. However, even if the PKS fuel is in a state in which the fiber portion is removed, there is still a fuel that shows an odor higher than the odor that can be shipped, and such fuel corresponds to “accepted fuel”. The product fuel is either a fuel that has been processed to remove the fiber part from the pre-processed fuel, and has an odor within the odor that can be shipped, or the received fuel has been deodorized. Includes both fuels that are now capable of exhibiting odors within the shippable odor.

  The above-mentioned received fuel and product fuel may be collectively referred to simply as “PKS fuel”.

  Here, as the supply source of the fuel before processing, the palm coconut shell supply place 40 (40A, 40B, 40C,...) And the biomass fuel distribution base 41 (41A, 41B, 41C,. )) Is assumed. Hereinafter, the distribution base 41 may be referred to as a “first distribution base 41” in order to distinguish it from the distribution base 1.

  In addition, the product fuel may be supplied from the first distribution base 41 for the purpose of accommodating fuel to the distribution base 1. In addition, when the first distribution base 41 does not have a function of performing a deodorizing process, the received goods fuel may be supplied from the first distribution base 41 to the distribution base 1. Furthermore, in the palm coconut shell supply place 40, when it has the equipment for removing the fiber part mentioned later, and the equipment for performing a deodorizing process, from the palm coconut shell supply place 40 to the distribution base 1, There may be cases where incoming fuel or product fuel is supplied.

  Further, as the shipment destination of the product fuel, a fuel consumer 50 (50A, 50B, 50C,...) And a biomass fuel distribution base 51 (51A, 51B, 51C,...) Different from the distribution base 1 are assumed. The In the following, the distribution base 51 may be referred to as a “second distribution base 51” in order to distinguish it from the distribution base 1 and the first distribution base 41.

  The palm coconut husk supply area 40 is assumed to be a place for supplying biomass fuel including palm coconut husks, and is specifically a Southeast Asian country such as Malaysia or Indonesia. In addition, the first logistics base 41 is assumed to be a place for supplying pre-processing fuel, received fuel, or product fuel for the purpose of providing PKS fuel to the logistics base 1, and specifically, It has the same function as the distribution base 1. For example, the logistics of PKS fuel between the first logistics base 41 and the logistics base 1 is based on inventory adjustments between logistics bases, sideways to logistics bases that are difficult to handle on large ships, This is performed as an aspect when dealing with inventory quantities of a plurality of logistics bases.

  The fuel consumer 50 is assumed to be a place (fuel demand place) where the PKS fuel (particularly product fuel) is scheduled to be used, or a business entity (company, local government, etc.) having this fuel demand place. An example of such a fuel demand place is a biomass power plant. Hereinafter, for the sake of simplicity, the description will be made assuming that the fuel consumer 50 is the fuel demand place itself.

  The second distribution base 51 is assumed to be a place where PKS fuel is supplied, and specifically has the same function as the distribution base 1 and the first distribution base 41.

  The palm coconut shell generates a good calorific value of 4000 kcal / kg or more by drying, has a low content of chlorine and alkali as repellent components as fuel, and has a generation amount of 10 million t or more per year. Etc., and has very favorable properties as a biomass fuel. However, in Malaysia and Indonesia, which are examples of the palm coconut shell supply area 40, some palm coconut shells are used as boiler fuel in local palm oil factories, but a considerable amount remains unused. It has been discarded and can be said to be a valuable unused biomass resource.

  The calorific value in this description refers to the true calorific value (low calorific value) described in JIS Z 73022-2 “Waste Solidified Fuel—Part 2: Calorific Value Test Method”.

  The palm coconut shell is an endocarp that wraps the kernel (Endocarp), a so-called seed shell, and has been crushed to about half because it has undergone a process of extracting the core inside the palm coconut shell supply site 40. An aggregate of plant fibers having a particle size of 5 mm to 40 mm and corresponding mechanical strength. Therefore, it is not necessary to process the pellets or the like to give mechanical strength, and it is a woody biomass fuel that can be used as it is.

<< Step S10, Step S20 >>
As described above, the distribution base 1 receives the pre-processing fuel or PKS fuel shipped from a supplier such as the palm coconut shell supply site 40 or the first distribution base 41 at the receiving facility 3 (steps S10 and S20). . Step S20 corresponds to the step (a).

  From the supply source such as the palm coconut shell supply area 40 and the first distribution base 41, fuel before processing, that is, biomass fuel containing palm coconut husk that needs to be subjected to predetermined processing at the time of shipment is supplied to the distribution base 1. Supplied. As another example, as described above, it is also assumed that received fuel or product fuel is supplied to the distribution base 1 from the supply source, particularly the first distribution base 41. In the latter mode, for example, as described above, the inventory amount in the distribution base 1 is small, and the demand for the fuel consumer 50 is obtained by receiving the interchange of the product fuel from other distribution bases in the vicinity (first distribution base 41). Respond to the case where it covers.

  The receiving facility 3 is preferably provided with a receiving facility 3a for sea transportation and a receiving facility 3b for land transportation. The marine transport receiving facility 3a receives unprocessed fuel or PKS fuel transported to the distribution base 1 by a sea transport means 91 such as a ship from a supplier such as the palm coconut shell supply area 40 or the first distribution base 41. It is a facility to accept. In addition, the land transportation receiving facility 3b is processed from the supply source such as the palm coconut shell supply area 40 or the first distribution base 41 to the distribution base 1 by the land transport means 92 represented by a transport vehicle such as a truck. Equipment for receiving pre-fuel or PKS fuel.

  More specifically, the marine transportation receiving facility 3a is composed of, for example, a harbor handling facility installed on the coast, and is preferably provided with a dedicated wharf. The marine transport receiving facility 3a is not particularly limited as long as it is a facility capable of receiving bulk goods, and a general unloader such as a grab bucket type, a continuous mechanical type, or a pneumatic type can be used. In particular, the grab bucket type is preferable from the viewpoint of adapting to products of various shapes and sizes.

  Some ships are equipped with cranes for cargo handling. As described above, in order to enable reception of pre-process fuel or PKS fuel that has been transported by a cargo ship equipped with a crane, the marine transport receiving facility 3a includes a receiving hopper equipped with a conveyor. It doesn't matter.

  Thereby, for example, it becomes possible to receive a large amount of unprocessed fuel from the palm coconut shell supply place 40 to the distribution base 1 through the sea transport means 91. In addition, by using the shipping facility 9a for shipping, which will be described later, also as the receiving facility 3a for shipping, a large amount of product fuel can be shipped to the shipping destination (fuel consumer 50, second distribution base 51) through the ship. . Thereby, distribution cost can be reduced.

  In addition, the land transportation receiving facility 3b is not particularly limited as long as it is a facility that can handle unloading from various types of trucks such as a dump type (bounce-up type) or a floor movement type (walking floor or slide deck), and a conveyor is attached. The received receiving hopper can be used effectively. As described above, the receiving facility 3 includes the land receiving facility 3b, so that it is possible to construct the logistics base 1 even in the inland area where the port cargo handling facility cannot be installed, and to promote the use of biomass fuel including PKS. Can contribute. Further, a land transportation shipping facility 9b, which will be described later, may also be used as the land transportation receiving facility 3b.

  In other words, the receiving facility 3 included in the distribution base 1 may include both the sea transportation receiving facility 3a and the land transportation receiving facility 3b, or only one of them.

<< Step S30 >>
In step S30, the fiber part is removed from the unprocessed fuel received by the receiving facility 3. This step S30 corresponds to the step (b). In addition, as described above, there are cases where the received fuel or product fuel is supplied from the supply source to the distribution base 1, and in this case, the received fuel is already received by the receiving facility 3 with the fiber portion removed. Therefore, this step S30 is omitted. Although FIG. 2 illustrates the case where step S40 is executed after step S30 is omitted and the case where step S60 is executed, these differences will be described later.

  The palm coconut shell has a beard-like fiber part, and the ratio of the odor emitted from the fiber part is large in the odor emitted from the palm coconut shell. Therefore, the fiber part is separated and removed by the separation equipment 4 from the pre-process fuel received by the receiving equipment 3.

  The separation equipment 4 is an equipment that can separate the fiber part from the pre-process fuel and is not particularly limited as long as it is a dry type. Various kinds of sieves such as a vibration sieve, an in-plane sieve, a rotary sieve (Trommel), and wind sorting It is preferable to use a sieve from the viewpoint of easy operation. When using a sieve as the separation equipment 4, the mesh opening of the sieve is preferably 0.6 mm to 11.2 mm from the viewpoint of separation accuracy of the fiber part. Thus, when a sieve having an aperture of 0.6 mm to 11.2 mm is used, the fiber part passes through the sieve and the remaining part remains on the sieve. In addition, the fuel before processing has been dried due to being exposed to normal air for a considerable period from the extraction of palm oil and fat at the palm coconut shell supply site 40 to the distribution base 1, and the PKS The bonded state of the fiber parts is very fragile, and the fiber parts can be easily separated by using the above-described separation equipment.

  The ratio of the fiber part in PKS is usually 1% by mass or less, and most of the unprocessed fuel received in step S20 remains on the sieve. The remaining portion on the sieve has a lower odor than the state at the time of acceptance in the distribution base 1 by removing the fiber portion having a strong odor.

  In addition, since the fiber part of the palm palm pattern separated from the fuel before processing by the separation equipment 4 has a strong odor as it is, for example, a heat treatment at 80 ° C. or higher using extraction steam described in Patent Document 1 Further, it may be used as biomass fuel after sufficiently deodorizing by the heat treatment at 115 ° C. or higher described in Patent Document 2. In that case, you may use as a binder at the time of shape | molding pellet-like biomass fuel. This heat treatment is an unnecessary process when generating the PKS fuel (product fuel) scheduled to be shipped by the distribution base 1 according to the present invention, and is a process performed only to generate other biomass fuel. is there. That is, the facility for performing this heat treatment may not be provided in the distribution base 1 according to the present invention.

<< Step S40 >>
In step S30, the odor is reduced as described above by removing the fiber portion from the fuel before processing. As a result, as the PKS fuel after the execution of step S30, there is a PKS fuel having an odor (shipable odor) that can be shipped to the consumer as it is (that is, product fuel), but it can still be shipped. Some products cannot be shipped as they are because they do not satisfy the odor (that is, received fuel).

  In this step S40, it is determined whether or not the PKS fuel has an odor within the odor that can be shipped. This step S40 corresponds to the step (c). Note that, in step S40, the PKS fuel that has been determined to exhibit an odor higher than the odor that can be shipped may be transported to the receiving item storage 6 as the receiving item fuel.

  As described above, the PKS fuel from which the fiber portion has already been removed may be supplied to the distribution base 1 from the supply source (the palm coconut shell supply area 40, the first distribution base 41). In this case, the PKS fuel received in step S20 does not need to be subjected to the fiber part removal process in step S30. However, since it is unclear whether or not this PKS fuel exhibits an odor within the odor that can be shipped, this step S40 is executed.

  Furthermore, as described above, it is clarified that the fiber part has already been removed from the supply source (palm coconut shell supply area 40, the first distribution base 41) and that the odor is within the odor that can be shipped. In some cases, the PKS fuel (that is, product fuel) is supplied to the distribution base 1. In particular, this corresponds to the case where the product fuel is stored in the first distribution base 41 and the product fuel is interchanged with the distribution base 1. In such a case, Step S60 is executed without passing through Step S30, Step S40, and Step S50 for the PKS fuel (product fuel) received in Step S20. Steps S50 and S60 will be described later.

  FIG. 3 is a flowchart showing an example of the flow of processing included in step S40. In the example illustrated in FIG. 3, step S40 includes each process of step S41, step S42, step S43, and step S44. As will be described later, step S44 may be omitted.

  First, the odor of the PKS fuel from which the fiber part has already been removed is measured by the odor measuring equipment 5 (step S41). At this time, after a part of the PKS fuel is extracted, odor measurement may be performed on the extracted PKS fuel. Step S41 corresponds to the step (c1) and the step (c2).

  As described above, the PKS fiber part may be removed at the time of acceptance in step S20. In this case, step S41 is executed after step S20.

  As shown in FIG. 3, the odor is measured in step S41 because it is used for comparison with the shippable odor in the next step S42. Here, the “shippable odor” in the present specification means that the odor of the product fuel at the time when it arrives under the fuel consumer 50 is the level of the nine-step pleasant / discomfort level display method in the olfactory measurement. It means a degree equivalent to “somewhat uncomfortable”.

  There are two methods for evaluating the odor density and strength: instrumental analysis methods such as gas chromatography and olfactory measurement methods such as the three-point comparison odor bag method. In addition, since the evaluation result cannot be confirmed in real time, it is difficult to use as a management method in the distribution base 1.

  The odor measuring equipment 5 is preferably an odor sensor using a metal oxide semiconductor gas sensor from the above viewpoint. Further, an odor sensor using such a metal oxide semiconductor gas sensor is preferable as the odor measuring equipment 5 because it can perform continuous measurement in addition to the convenience of measurement operation and the ability to obtain results in a short time.

  Specification that PKS fuel is blocked from outside air such as hooded conveyors (belt conveyors, chain conveyors, etc.) so that odors do not diffuse as one of the specific aspects of PKS fuel odor measurement method using odor measuring equipment 5 It is possible to use a method for measuring the odor while transporting the inside of the distribution base 1 with the transport facility. As a more specific example, the detection unit of the odor measurement facility 5 is installed at a position upstream from the center of the conveyor in the conveyor hood.

  For example, using the indication value of the odor measuring equipment 5 used in the case where the 9-step pleasure / discomfort level display method is −1 as an index, the odor of the PKS fuel is determined as the odor that can be shipped. It is determined whether or not it is satisfied (step S42, step S43).

  For example, when KALMOR-Σ (Calmore Co., Ltd.) is used as the odor measuring equipment 5, when the atmospheric measurement value (blank) at a place where no PKS fuel exists is 200, 10% of pulverized coal is mixed with PKS fuel and unpleasant odor Since the odor sensor instruction value is 600 when it is reduced to an acceptable level, the threshold value 600 may be adopted as the index of the odor measuring equipment 5.

  When the odor of the PKS fuel measured by the odor measuring equipment 5 is within the odor that can be shipped (Yes in Step S43), Step S60 described later is executed. On the other hand, if the odor of the PKS fuel measured by the odor measuring equipment 5 is higher than the odor that can be shipped (No in step S43), it is determined that the PKS fuel is the received product fuel, and the received product yard 6 Transported and stored (step S44). The received product fuel stored in the received product storage area 6 is subjected to a deodorizing process so as to satisfy a shippable odor in step S50 described later. Step S43 corresponds to step (c3), and step S44 corresponds to step (c4).

  As described above, the distribution base 1 has the receiving goods storage 6 and the product storage 8. The receiving place 6 is a place for storing PKS fuel (receiving goods fuel) that has a higher odor than the shippable odor, and the product place 8 is for storing PKS fuel (product fuel) that shows an odor within the shipping odor. It is a place to do.

  It should be noted that the PKS fuel determined to be the received fuel in step S43 is not temporarily stored in the received product storage place 6, that is, step S44 is not executed, but immediately relates to step S50 described later. The deodorizing process may be performed. In FIG. 3, the case where processing is performed in such a flow is indicated by a broken line with an arrow.

<< Step S50 >>
Next, a deodorizing process is performed on the received fuel, which is a PKS fuel that exhibits a higher odor than the shippable odor, and the PKS fuel (product fuel) that exhibits an odor within the shippable odor is improved. This step S50 corresponds to the step (d). As shown in FIG. 1, the distribution base 1 includes a deodorization processing facility 7 for executing step S50.

  Note that, as described above with reference to FIG. 3, this step S50 may be performed on the received fuel stored in the receiving product storage place 6, and is determined as the received fuel in step S43. Then, it may be executed as it is without being stored in the receiving item storage 6. Furthermore, although omitted in FIG. 2 for the purpose of avoiding complications, in step S20, the fuel in the state accepted in the distribution base 1 has an odor that is higher than the odor that can be shipped although the fiber portion is originally removed. In other words, if it is clear that the fuel is an accepted product, step S50 may be executed after step S20 without passing through step S30 and step S40.

  The deodorizing treatment includes mixing with wood chips or wood pellets of tree species other than palm palm, spraying of a deodorizing agent, aeration of room temperature air, and the like. In step S50, all these processes may be executed, or only some of these processes may be executed.

  FIG. 4 is a block diagram schematically showing an example of the configuration of the deodorizing treatment facility 7. In the example shown in FIG. 4, the deodorizing treatment equipment 7 is a mixing equipment 71 for mixing wood chips or wood pellets of tree species other than palm palm to the received product fuel, and a deodorant for the received product fuel. It comprises a spraying facility 72 for spraying and a venting facility 73 for allowing normal temperature air to vent to the received fuel.

  As described above, the mixing facility 71 is a facility for dry-mixing the received fuel and the wood chips or wood pellets of tree species other than palm palm, and is limited to the device mode as long as the mixing function is exhibited. In addition, heavy machines such as wheel loaders, mixers with blades, rotary sieves, etc. can be used effectively.

  Wood chips or wood pellets of tree species other than the above palm palms have the effect of weakening the unpleasant odor emitted from the received fuel by strongly emitting a preferred scent or adsorbing the odor component of the unpleasant odor, etc. Chips and pellets made of cedar, cypress, larch, red pine, cherry and the like are preferred. The wood chips and the like are mixed with the received fuel (PKS fuel) and shipped as biomass fuel, so the size is 5 cm or less on the long side equivalent to PKS and the moisture content is 20 mass% or less. Those are preferred.

  What is necessary is just to set the mixing ratio with wood chips etc. of tree species other than acceptance fuel and palm palm so that content of palm palm shell in the biomass fuel after mixing may be 50 mass% or more.

  The deodorant spraying facility 72 is a facility for spraying a specific deodorant on the received fuel, and is not limited to the device mode as long as the spraying function or the chemical spraying function is provided. Scattering type, additive type, etc. can be used effectively.

  As the deodorant used in the deodorant spraying equipment 72, a sterilizing deodorant using ozone oxidizing power such as ozone mist or a neutral deodorant such as vegetable essential oil or chlorine dioxide is preferably used. it can. In particular, the deodorization method using ozone can be continuously performed by preparing an ozone generator, so that the running cost of drug purchase can be suppressed.

  The room temperature air ventilation equipment 73 is equipment intended to dry and deodorize the received fuel. In general, biomass fuel (including fuel before processing) containing PKS transported from the palm coconut shell supply site 40 to the distribution base 1 contains about 25% by mass of moisture, but this moisture content is 8% by mass or less. By doing so, the unpleasant odor emitted by PKS can be reduced to an acceptable level. A simple method for reducing the moisture content of biomass fuel containing PKS (here, the received fuel) to 8% by mass or less is to expose the received fuel to ambient air in an environment where rain does not occur. is there. More specifically, it may be simply left in a place where natural drying such as sun drying or indoor drying can be performed, and more efficiently, a gas outlet is provided below the floor of the place for receiving fuel. Install a ventilation pipe, insert a ventilation pipe with a gas outlet directly into the pile of received fuel, and forcibly vent normal temperature air into the received fuel, or use a blower to put the pile of received fuel at room temperature Just blow the atmosphere.

  In the example shown in FIG. 4, the deodorizing treatment equipment 7 is configured to include all of the mixing equipment 71, the deodorant spraying equipment 72, and the room temperature air ventilation equipment 73. 71, 72, 73) may be provided.

<< Step S60 >>
The received product fuel deodorized in step S50 becomes a product fuel exhibiting an odor within the shipmentable odor, together with the fuel determined to exhibit the odor within the shipmentable odor in step S40 (more specifically, step S43), Stored in the product area 8. At this time, the product fuel is stored in a product storage area 8 that differs according to quality. This step S60 corresponds to the step (e).

  As described above, it is clarified that the fiber part has already been removed from the supply source (palm coconut shell supply area 40, first distribution base 41) and that the odor is within the odor that can be shipped. In some cases, the PKS fuel (that is, product fuel) is supplied to the distribution base 1. In such a case, as shown in FIG. 2, after the product fuel is received in the distribution base 1 in step S20, step S30, step S40, and step S50 are omitted, and this step S60 is executed.

  FIG. 5 is a flowchart showing an example of the flow of processing included in step S60. In the example illustrated in FIG. 5, step S60 includes each process of step S61, step S62, step S63, step S64, and step S65. As will be described later, in step S20, when the product fuel is received from the supply source (palm coconut shell supply place 40, first distribution base 41) into the distribution base 1, step S61, step S62, and step S63 may be omitted. In FIG. 5, the case where processing is performed in such a flow is indicated by a broken line with an arrow.

  First, a part of the product fuel is extracted from the product fuel that has been transported to the product site 8 (step S61). For example, as shown in FIG. 1, the distribution base 1 may include a product fuel sampler 12 for executing step S61. The product fuel sampler 12 is a sample collection device for analysis and test, and there is no particular limitation on the sampling method or the like as long as a sample with high representativeness can be collected. In general, as described in JIS K 0060 “Industrial Waste Collection Method” and JIS M 8100 “Powder Mixture – General Rules for Sampling Method”, the entire flow of the object to be dropped at the outlet of the conveyor or feeder A sampler that can be sampled from the width is preferably employed. This step S61 corresponds to the step (e1).

  Next, the extracted product fuel is analyzed (step S62). For example, as shown in FIG. 1, the distribution base 1 may include an analysis facility 11 for executing step S62.

  The analysis equipment 11 is not particularly limited as long as it is a device that can cope with necessary test / analysis items, and a general-purpose test device or analysis device can be used. Further, the analysis equipment 11 may have an unmanned configuration using a robot handling / automation system or the like. As an example, the analysis equipment 11 has a function of testing and analyzing the content of alkali metal, content of chlorine, content of water, and calorific value of the product fuel.

  The measurement of the amount of chemical components (alkali metal, chlorine, etc.) contained in the product fuel is not particularly limited as long as it is an analytical method capable of obtaining the desired amount of chemical components, but from the viewpoint of versatility and analysis accuracy, It is preferable to use an absorptiometric analysis method, an emission spectroscopic analysis method, an atomic absorption spectroscopic method, or an ICP emission spectroscopic analysis method for a solution obtained by completely dissolving an ashed sample with an acid. Moreover, the chlorine content can use the test method of JIS Z 7302-6 "Waste solidified fuel-Part 6: Total chlorine content test method". The ashing of the product fuel is preferably carried out at a low temperature of 600 ° C. or lower from the viewpoint of preventing dissipation of volatile components such as alkali.

  For example, the method described in JIS Z 7302-3 “Waste Solidified Fuel—Part 3: Moisture Test Method” can be used to measure the amount of moisture (or moisture content) contained in the product fuel. . Specifically, the mass before and after heating when heated at a drying chamber temperature of 107 ± 2 ° C. for 1 hour may be used. In addition, instrumental analysis such as thermobalance analysis (TG) can be used.

  Moreover, for the measurement of the calorific value of the product fuel, for example, a method described in JIS Z 7302-2 “Waste Solidified Fuel—Part 2: Calorific Value Test Method” can be used.

  However, the analysis equipment 11 does not have to have all the analysis functions of the alkali metal amount, chlorine amount, moisture amount (water content), and calorific value contained in the product fuel, at least of these What is necessary is just to provide one or more analysis functions.

  The method of transporting the product fuel extracted by the product fuel sampler 12 to the installation location of the analysis equipment 11 is not particularly limited, but an air pipe system capable of automatically transporting a sample is suitable. used.

  Next, based on the result analyzed by the analysis equipment 11, the quality of the target product fuel is specified (step S63). Step S63 corresponds to the step (e3).

  As a method for specifying the quality of the product fuel, any quality item and any number of levels in each quality item may be used. For example, when sorting by three items of calorific value, moisture content and alkali content, the two items of calorific value and moisture content are classified into two levels of large and small according to a specific threshold, and the required quality from the fuel consumer 50 However, it is possible to adopt a method of classifying 12 types (= 2 × 2 × 3) as a whole, with the fine alkali content classified into three levels of large, medium and small. Chlorine content may be included in the classification item.

  Next, based on the quality of the product fuel specified in step S63, the product storage 8 that is the storage destination of the product fuel is selectively specified from among the product storages (8a, 8b,...) ( Step S64). As described above, the quality of the product fuel to be stored in each product storage 8 is different. Information on the quality of the product fuel assigned to each product storage 8 may be stored in advance on a storage unit or a paper surface of an information processing apparatus (not shown). Based on the stored information, the product storage 8 where the product fuel is stored is specified.

  Then, the product fuel is transported to and stored in the specified product place 8 (step S65). In addition, heavy machinery such as wheel loaders and bulldozers and pneumatic feeding can be used for transporting product fuel in the field, but from the viewpoint of efficiency, work safety, prevention of scattering of woody biomass fuel and equipment costs, etc. It is preferable to use conveyors such as a screw conveyor and a chain conveyor. Note that PKS, wood chips, wood pellets, and the like are likely to cause a clogging state called bridging, and therefore it is preferable to devise measures to prevent clogging of baffle plates or the like at locations having a path restriction.

  The product storage area 8 (8a, 8b,...) Is not particularly limited as long as it is a facility that can store the product fuel without causing rain or the like, and does not interfere with receiving and discharging the cargo. Buildings and silos can be used effectively. From the viewpoint of preventing water wetting and preventing spontaneous ignition during the storage period, a storage facility equipped with a product fuel pile turning device as described in, for example, Japanese Patent No. 6381836 is more preferable. In addition, when using a building with a roof as the product storage 8, if it can manage so that the product fuel classified according to quality may not mix, a several building can store a several product fuel.

  A function of analyzing the quality of biomass fuel (particularly product fuel in this case) supplied to the distribution base 1 depending on a supply source of biomass fuel including PKS (palm coconut shell supply area 40, first distribution base 41). In this case, the supplier may notify the distribution base 1 of information relating to the quality of the PKS fuel (product fuel) supplied to the distribution base 1. . In this case, based on the notified information relating to the quality of the PKS fuel, the product storage 8 serving as the storage destination may be specified, and the product fuel may be stored in the specified product storage 8. (Step S64, Step S65). In this case, the analysis process for the product fuel (step S61, step S62, step S63) may not necessarily be performed in the distribution base 1. In FIG. 5, the case where step S64 is executed after step S20 is indicated by a broken line represents a flow corresponding to this process. In particular, in this case, as shown in FIG. 2, after the fuel is received in step S20, step S60 may be executed without executing steps S30, S40, and S50.

<< Step S70 >>
Next, the product fuel stored in the product yard 8 is shipped to the shipping destination (the fuel consumer 50, the second distribution base 51). This step S70 corresponds to the step (f).

  FIG. 6 is a flowchart showing an example of the processing flow included in step S70. In the example illustrated in FIG. 6, step S70 includes each process of step S71, step S72, step S73, step S74, step S75, and step S76.

  Each fuel consumer 50 (50A, 50B, 50C,...) And the like is given information on the specific quality (required quality) to be ordered. In the distribution base 1, first, the product storage 8 where the product fuel satisfying the required quality is stored is specified (step S71). This step S71 corresponds to the step (f1).

  Next, a part of the product fuel is extracted from the large amount of product fuel stored in the specified product storage 8 (step S72). This step S72 corresponds to the step (f3).

  For example, as shown in FIG. 1, the distribution base 1 may include a shipment sampler 13 for executing step S72. The shipment sampler 13 can have the same configuration as the product fuel sampler 12 described above. The product fuel sampler 12 may also serve as the shipment sampler 13.

  Next, the extracted product fuel is analyzed (step S73). This step S73 corresponds to the step (f4). In the example shown in FIG. 1, the case where the product fuel extracted by the sampler 13 for shipment is analyzed by the analysis equipment 11 similar to step S62 is illustrated. However, the distribution base 1 may include a dedicated analysis facility 11 to be executed in step S73, in addition to the analysis facility 11 used in step S62.

  Next, based on the result analyzed by the analysis equipment 11, the quality to which the product fuel extracted by the shipment sampler 13 belongs is specified, and whether or not the specified quality satisfies the required quality is confirmed. (Step S74). This step S74 corresponds to the step (f5) and the step (f6). When the target product fuel does not satisfy the required quality, the process may return to step S71 and specify another product storage 8 in which the target product fuel is stored again.

  When it is confirmed in step S74 that the target product fuel satisfies the required quality, a large amount of product fuel stored in the product storage 8 is transported to the shipping facility 9 (step S75).

  The shipping facility 9 preferably includes a shipping facility 9a for sea transportation and a shipping facility 9b for land transportation. The shipping equipment 9a for sea transportation is not particularly limited as long as it is equipment that can be shipped according to the package form, such as a ship loader for bulk loading, a crane or a hoist for containers or flexible containers. Further, the land transportation shipping facility 9b is not particularly limited as long as it is a facility that can be shipped according to the package form, such as a hopper for loading on a bulk truck or a forklift that handles a flexible container.

  However, the shipping facility 9 included in the distribution base 1 may include only one of the shipping facility 9a for sea transportation and the shipping facility 9b for land transportation.

  Then, the product fuel is supplied from the marine shipping facility 9a by the marine transportation means 93 such as a ship or the fuel consumer 50 (50A, 50B, 50C,...) Or the second logistics base 51 (51A, 51B, 51C,. ) And by the land transportation means 94 represented by a transport vehicle such as a truck from the land transportation shipping facility 9b or the second logistics base 51 (51A, 51B). , 51C,...) (Step S76). This step S76 corresponds to the step (f2).

  It should be noted that the properties of the product fuel are unlikely to change during storage unless wetness or the like occurs. Further, the quality of the product fuel stored in the product storage area 8 is analyzed and specified when the storage site product storage area 8 is determined in step S60. For this reason, in many cases, the quality of the product fuel stored in the product storage area 8 continues to ensure the quality associated with the product storage area 8 in which the product fuel is stored even immediately before shipment. From this point of view, step S72 and step S73 may be omitted, and in step S74, it may be confirmed only whether the quality of the product fuel associated with the storage location product site 8 satisfies the required quality. .

  In addition, the PKS which shows an odor higher than the odor that can be shipped in addition to the product fuel from the shipping facility 9a or the shipping facility 9b to the second logistics base 51 (51A, 51B, 51C,...). Fuel (received product fuel) or biomass fuel (pre-processing fuel) containing PKS before the fiber part is removed may be shipped.

  The amount of PKS fuel (received fuel) that can be stored in the receiving goods storage 6 of the distribution base 1 and the amount of PKS fuel (product fuel) that can be stored in the product storage 8 (8a, 8b, 8c,...). The total amount is preferably 5,000 t or more, more preferably 10,000 t or more, and particularly preferably 20,000 t or more. By providing such a storage capacity, the distribution base 1 can stock necessary fuel for several days in a 75 MW class biomass power generation boiler, for example.

  In the following, specific test examples are shown to describe the present invention in more detail, but the present invention is not limited to the embodiments of these test examples.

  As a sample, a Tenera-type PKS (a1) produced in Malaysia (a calorific value: 4800 kcal / kg) and a shell obtained by separating a whisker-like fiber part from the PKS using a sieve having a mesh opening of 1.7 mm ( a2) (Heat generation amount: 4800 kcal / kg), separated beard-like fiber part (a3), chip mixture product A in which red pine chips (water content: 30% by mass) are mixed with the shell part (a2) in an equal amount (A4) (calorific value: 4000 kcal / kg), and chip mixture B (a5) (exothermic) obtained by mixing equal amounts of chips obtained by drying the red pine chips to a moisture content of 0.8% by mass into the shell (a2) Amount: 4750 kcal / kg) was prepared.

  PKS (a1) corresponds to the pre-processing fuel accepted at the distribution base 1 in step S20. The shell (a2) corresponds to the PKS fuel (here, the received product fuel) obtained by separating the fiber portion from the pre-processing fuel in step S30. In addition, the fiber part (a3) separated here is a fuel that is not used as a PKS fuel, and as described above, it can be used as another biomass fuel, such as a binder of pellet biomass fuel.

  In addition, the chip mixture A (a4) and the chip mixture B (a5) are both PKS fuels (here, the deodorized treatment is performed on the received fuel by the deodorization processing equipment 7 in step S50). Product fuel). The chip mixture B (a5) differs from the chip mixture A (a4) in the content of the deodorizing process.

  About said samples a1-a5, the intensity | strength of the odor according to moisture content was measured. The moisture content was measured in accordance with JIS Z 7302-3 “Waste Solidified Fuel—Part 3: Moisture Test Method”, that is, when the sample was heated and dried at 107 ± 2 ° C. for 1 hour. The difference in mass before and after drying was defined as moisture as a mass percentage with respect to the sample. The intensity of odor was measured by the following procedure. Table 1 shows the measurement results of the odor intensity according to the moisture content of each sample. In addition, in the odor sensor instruction value used for the measurement of the odor intensity, the odor intensity at which a person can tolerate discomfort is 600 or less.

<< Measurement procedure of odor intensity >>
(I) 100 g of the sample was sealed in a 1 L plastic container.
(Ii) It was left to stand in a constant temperature environment of 30 ° C for 1 day.
(Iii) Using a flex pump, the gas in the plastic container containing the sample was collected in a 3 L gas bag.
(Iv) The strength of the odor of the gas in the collected gas bag was measured using an odor sensor (Neo Sigma manufactured by Calmore Co., Ltd.).

From Table 1, the following five points are confirmed.
(I) Solid PKS (a1) has a strong odor even when the moisture content is dried to 12% by mass.
(Ii) PKS has a weak odor by removing the fiber part.
(Iii) If the moisture content of the PKS shell part from which the fiber part has been removed is 8% by mass or less, the odor is weakened to an acceptable level.
(Iv) Mixing wood chips is effective in reducing odor from PKS.
(V) The more the wood chips used for mixing are dried, the greater the effect of reducing the odor from PKS.

  Next, the strength of the odor when water was added to the shell portion once dried to weaken the odor was examined. This is for confirming the necessity of water-wetting prevention measures for storage of PKS after the deodorizing process is performed.

  The sample was prepared by spraying the PKS shell (a2) until the moisture content was 0% by mass, and then spraying water so as to obtain a predetermined moisture content. The method for measuring the odor intensity is the same as in the above test. The results are shown in Table 2. In Table 2, the odor sensor instruction value 400 at a moisture content of 0% by mass indicates an almost odorless state.

From Table 2, the following two points are further confirmed.
(Vi) The strength of the odor of PKS increases as the moisture content increases.
(Vii) Compared with the results in Table 1, the relationship between the moisture content of PKS and the intensity of odor is reversible, and it is preferable that the storage facility for PKS has a function of preventing water wetting.
