Description

Pelletized wood biomass fuel distribution method, Pelletized wood biomass fuel distribution base

The present invention relates to a distribution method for pelletized wood biomass fuel and a distribution base for pelletized wood biomass fuel.

Due to the enforcement of the Act on Special Measures for Renewable Energy, renewable energy such as tree trunks and branches, cutting chips, sawdust, bark, and construction waste wood is used as an alternative fuel for power generation boilers and cement clinker burning equipment. Is being developed.

For example, when using felled lumber as fuel for a boiler for power generation, the amount of felled lumber required will be tens of thousands of tons or more per year. However, there are many problems in stable and efficient supply of woody biomass as fuel, such as seasonal fluctuations in the supply amount derived from the growth of trees and the problem of mass transportation between supply and demand areas. ing.

In addition, where the fuel is required to have stable quality such as calorific value, in order to secure the required supply amount throughout the year when considering the above-mentioned seasonal fluctuations in the supply amount of the individual wood biomass fuels, It will be necessary to combine multiple sources and multiple types of woody biomass. In such combined use or mixed use of woody biomass fuels, a technique for stabilizing the quality is required so that the quality characteristics of the woody biomass fuel as a final product do not change.

For example, in Patent Document 1 below, when a coal/wood biomass mixed fuel obtained by mixing wood biomass (felled wood, sugar cane, oil palm, chaff, etc.) and coal is used, a fuel collection/sales company Selling coal/wood biomass mixed fuel blended according to the conditions required by fuel users for biomass and coal (type of wood biomass, mixing ratio of coal and wood biomass, calories burned, etc.), coal/wood biomass A blended fuel collection and sale system and method is disclosed.

JP, 2007-58440, A

However, the system and method for collecting and selling coal/woody biomass mixed fuel disclosed in Patent Document 1 is not limited to the technology related to information processing for matching the purchase request information on the consumer side with the inventory information on the supplier side. However, this is not a drastic countermeasure technology for stabilizing supply and stabilizing quality.

The present invention has been made in view of the above-mentioned problems in distribution of woody biomass fuel, and particularly aims to stably supply pelletized woody biomass fuel having predetermined quality characteristics to users. To do.

The present invention is a distribution method of pelletized woody biomass fuel,
A step (a) of receiving, from a fuel manufacturing site, a product fuel which is a pellet-like woody biomass fuel in a state of being ready for shipment, or a received fuel which is a woody biomass fuel that needs to be processed to produce the product fuel. ,
The storage location of the received fuel received in the step (a) is specified according to the quality of the received fuel from a plurality of received product storage areas, and the received fuel is stored in the specified received product storage area. Storing step (b),
A step (c) of performing a predetermined processing process on the received fuel stored in the received storage to generate the product fuel;
The product fuel received in the step (a) and the product fuel generated in the step (c) are specified from a plurality of product storage areas according to the quality of the product fuel, and the specified product fuel is specified. Storing the product fuel in a product storage area (d),
And a step (e) of shipping the product fuel stored in the product storage area to a fuel demand area.

According to the above method, the fuel that is brought in from various fuel manufacturing locations can be received at one location and stored in different storage locations depending on the quality.

The fuel delivered from the fuel manufacturing site may or may not be a pelletized fuel with a quality that allows it to be shipped to the demand area as it is (hereinafter referred to as “shippable quality”). Therefore, it may not be shipped as it is, and it is assumed that it is a fuel that requires processing. Such differences are due to the manufacturing/processing capabilities of the fuel manufacturing site. In the present specification, the former fuel is referred to as “product fuel” and the latter fuel is referred to as “accepted fuel”.

 The received fuel that is brought in from the fuel manufacturing site is stored in the received goods storage area specified according to the quality. Then, the product fuel is generated by subjecting the received product fuel to a predetermined processing treatment. According to the above method, since the processing can be performed in the facility that receives the received fuel (hereinafter, referred to as “distribution base”), the fuel that has been brought in from the fuel manufacturing site is pelletized, for example. Even if the quality is such that the product cannot be shipped as it is, it is possible to convert the fuel into a state in which the product can be shipped (the product fuel described above).

According to the above method, since the received fuel is also stored in the different receiving goods storage space depending on the quality, it is possible to grasp the quality of the received fuel used during processing. The quality of the fuel (product fuel) generated by performing the processing depends on the quality of the received fuel used for the processing. Therefore, even if the stock of the required quality product fuel is insufficient, it is possible to easily specify the received product necessary to generate the product fuel of the relevant quality. On the other hand, by performing the processing, it is possible to generate the product fuel of the required quality on the spot (in the distribution base).

Also, the product fuel generated by processing the received fuel in this way is stored in the product storage area that differs according to quality. Therefore, even if a product fuel (pellet-like woody biomass fuel) of a specific quality (hereinafter referred to as "demand quality") is ordered from the demand area, the distribution base of the product fuel that satisfies the demand quality is ordered. It is possible to recognize the stock quantity of the product in a short time. Even if the inventory quantity is less than the demand quantity, the received fuel before processing is stored in the received goods storage and can be processed in the distribution base. Within, it is possible to meet the demand by producing a product fuel satisfying the demand quality by performing processing on the received fuel having a predetermined quality. In this way, the product fuel that is processed as necessary to satisfy the demand amount and the demand quality is shipped to the demand place.

Note that, as described above, depending on the fuel brought in from the fuel manufacturing site, there are cases where it shows a quality that satisfies the condition (shipable quality) of the product fuel. Such fuel may be stored in a predetermined product storage area designated according to quality, not in the received product storage area.

As described above, according to the distribution method of the pelletized woody biomass fuel according to the present invention, since the product fuel is stored in different storage locations depending on the quality, a plurality of pelletized woody biomass fuels having different qualities are stored. In addition to being able to ship effectively, the processing can be performed on the spot to improve the efficiency of the distribution of the woody biomass fuel.

The step (e) includes

According to the above method, since the quality of the received fuel received in the step (a) can be specified in the receiving place (distribution base), it is possible to easily specify the receiving goods storage place where the received fuel is stored. .. Note that, depending on the fuel manufacturing location, there are cases where the analysis of the calorific value and/or the predetermined chemical components of the carried-in fuel (received fuel) can be performed with a certain degree of accuracy. In such a case, when the received fuel is received in the step (a), the quality information is also acquired, so that the received fuel storage space of the received fuel is stored based on the acquired quality information. It may be specified.

The step (d) includes
A step (d1) of extracting at least a part of the product fuel received in the step (a) and the product fuel generated in the step (c);
A step (d2) of analyzing the calorific value and/or a predetermined chemical component of the product fuel extracted in the step (d1);
On the basis of the analysis result of the step (d2), the product is classified according to the range to which one or more indexes selected from the group consisting of the content of alkali metal, the content of chlorine, the content of water, and the amount of heat of the product fuel belong The process may include the step (d3) of specifying the quality of fuel.

As mentioned above, the fuel delivered from the fuel manufacturing site may include fuel (product fuel) that satisfies the quality that can be shipped. By including the steps (d1) to (d3), since the quality of such product fuel can be specified on the spot (in the distribution base), the product storage place of the storage destination can be easily designated.

In addition, the product fuel generated by the processing performed in the step (c) is as expected depending on the mode of the processing, even if the quality of the received fuel used for the processing is known. In some cases, the quality may not be the same. By having the above steps (d1) to (d3), the quality of the product fuel produced by the processing can be specified on the spot (in the distribution base), and thus it is suitable as a storage destination. You can easily specify the product storage area.

In addition, when the demand amount ordered from the demand place exceeds the inventory amount and the shortage amount is covered by the processing process in the step (c), the product fuel generated through the processing process is used to store the product fuel generated through the processing process. You may want to ship it as is without storing it in. Then, at this time, there is a case where it is desired to confirm whether or not the product fuel generated by performing the processing process satisfies the demand quality.

For cases like this,
The step (e) of shipping the fuel to the demanded area is
A step (e3) of extracting at least a part of the product fuel generated in the step (c),
A step (e4) of analyzing the calorific value and/or a predetermined chemical component of the product fuel extracted in the step (e3);
On the basis of the analysis result of the step (e4), the product according to the range to which one or more indexes selected from the group consisting of the content of alkali metal, the content of chlorine, the content of water, and the calorific value of the product fuel belong. A step (e5) of specifying the quality of the fuel,
It may have a step (e6) of confirming that the quality of the product fuel specified in the step (e5) satisfies the quality standard according to the demand of the consumer.

The received fuel may include woody biomass derived from the palm oil industry.

Further, the distribution method of the pelletized woody biomass fuel,
Having a step (f) of receiving waste white clay,
The predetermined processing in the step (c) may include a process of mixing and molding the waste white clay received in the step (f) and the received fuel.

According to the above method, even if the received fuel that does not satisfy the shipment quality is carried in, by performing the processing on the received fuel, it is possible to obtain a high quality product having high mechanical strength. A product fuel can be produced.

The step (a) includes a step of receiving the product fuel or the received product fuel transported by land or sea from the fuel manufacturing site,
The step (e) may include a step of transporting the product fuel stored in the product storage area to the demand area by land or sea.

Further, the present invention is a distribution base for pelletized wood biomass fuel,
A shipping facility for shipping product fuel, which is a pelletized woody biomass fuel ready for shipping, to the fuel demand area,
Product storage for storing the product fuel by quality,
An accepting facility for accepting an accepting fuel, which is a woody biomass fuel that needs to be processed to generate the product fuel, from a fuel manufacturing site,
An incoming goods storage for storing the incoming fuel by quality,
And a processing facility for performing the processing on the received fuel to generate the product fuel.

The receiving facility may also receive the product fuel from the fuel manufacturing site.

According to the pelletized wood biomass fuel distribution base with the above configuration, a storage base and a shipping base for stabilizing the supply of the pelletized wood biomass fuel (product fuel) will be realized. The higher the quality of the pelletized woody biomass fuel, the higher the price. Therefore, it is expected that the quality of the pelletized woody biomass fuel demanded by the demand area will differ depending on the usage conditions used in the demanded area. It Therefore, it is desirable that the product fuel satisfying the quality (demand quality) required from various demand places be stored and ready for shipment. According to the above distribution base, since the product fuels are stored according to the quality, it is easy to specify the product fuels that satisfy the demand quality required from the demand area.

Even if the stock quantity of the product fuel satisfying the demand quality is insufficient with respect to the demand quantity, the shipping facility quality is not satisfied because the processing facility equipment exists in the distribution base. By processing the received fuel, it is possible to generate a product fuel satisfying the shippable quality and the demand quality in the distribution base, whereby the demand amount can be covered.

Therefore, seasonal fluctuations in the supply amount of woody biomass fuel and fluctuations in the supply amount due to physical distribution troubles can be buffered by the storage capacity of the distribution base according to the present invention, and stable supply to the demanded areas becomes possible.

The distribution base for the pelletized wood biomass fuel may have an analytical facility for analyzing the received fuel and/or the product fuel with respect to the calorific value and/or a predetermined chemical component.

With this configuration, the received fuel and/or the product fuel can be analyzed in the distribution base, and the quality of each fuel can be specified. As a result, it is possible to appropriately specify the storage place for the received products or the storage place for the products.

In particular, the pelletized wood biomass fuel distribution base is equipped with analytical equipment for analyzing product fuels, so that the quality characteristics of the goods loaded on transportation means such as ships and trucks can be confirmed or It becomes possible to ship after confirming the quality characteristics of the product, and it is possible to prevent the shipment of product fuel that does not satisfy the demand quality.

In addition, analysis equipment that analyzes the received fuel, analysis equipment that analyzes the product fuel generated by processing the received fuel, and product fuel immediately before shipping The analytical equipment for performing the analysis may be common equipment or separate equipment.

The processing equipment is
Crushing equipment for crushing the received fuel,
A mixing facility for mixing the received fuels that have been crushed by the crushing facility or before being crushed, or a crushed received fuel and a fuel material other than the received fuel,
A molding facility for molding the received fuel mixed by the mixing facility into pellets may be provided.

The processing equipment is
A foreign matter removal facility for removing foreign matter contained in the received fuel,
It may have a classification facility for classifying the received fuel that has been crushed by the crushing facility or before being crushed.

The receiving facility has a function of receiving waste white clay,
The mixing facility may have a function of mixing the crushed received fuel and the waste clay.

As a result, it becomes possible to ship pelletized woody biomass fuel, which is made of a mixture of woody biomass and waste white clay, which has excellent mechanical strength, from the distribution base of pelletized woody biomass fuel according to the present invention.

The pelletized wood biomass fuel distribution base has a port cargo handling facility installed on the coast,
The port cargo handling facility may constitute the shipping facility and the receiving facility.

As a result, for example, it is possible to receive a large amount of woody biomass fuel derived from palm palm, which is shipped from Malaysia and Indonesia, and also possible to ship a large amount using ships, thus reducing the distribution cost of woody biomass fuel. be able to.

The receiving facility has a function of receiving the received fuel conveyed by a transportation vehicle,
The shipping facility may have a function of shipping the product fuel to the demand area by a transportation vehicle.

As a result, it becomes possible to accept a small amount of woody biomass, such as the amount of construction waste materials that were conventionally disposed of at refuse incineration facilities and final disposal sites, and contribute to the construction of a resource recycling society. It will also be possible to respond to inland areas and small demand.

At the distribution base of the pelletized wood biomass fuel, the total 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 storage area is 15,000 t or more. Is more preferable, 30,000 t or more is more preferable, and 60,000 t or more is particularly preferable. Due to the storage capacity of this woody biomass fuel, it is possible to stock the required fuel for several weeks in, for example, a 75 MW class biomass power generation boiler.

According to the present invention, it becomes possible to stably supply the pelletized woody biomass fuel that satisfies the quality required by the demand place.

It is a block diagram which shows typically an example of a structure of a pre-processing facility.

An embodiment of a distribution method of a pelletized wood biomass fuel and a distribution base of a pelletized wood biomass fuel according to the present invention will be described with reference to the drawings as appropriate.

FIG. 1 is a block diagram schematically showing a configuration of an embodiment of a distribution base for pelletized woody biomass fuel according to the present invention. FIG. 2 is a flow chart schematically showing a processing flow of a method for distributing a pelletized woody biomass fuel according to the present invention.

The distribution base 1 for pelletized woody biomass fuel shown in FIG. 1 (hereinafter, abbreviated as “distribution base 1” as appropriate) includes a receiving facility 3, a receiving facility 4, a processing facility 5, and a product facility 6. And shipping facility 7. The physical distribution base 1 shown in FIG. 1 is one mode for carrying out the physical distribution method shown in FIG.

Note that in the following description, the reference numerals of the steps described in the flowchart shown in FIG. 2 are appropriately referred to.

The distribution base 1 receives the biomass fuel shipped from the fuel manufacturing site 40 (40a, 40b, 40c, 40d, 40e,...) In the receiving facility 3 and stores the biomass fuel, and stores the stored biomass fuel from the shipping facility 7 as fuel. It has a function of shipping to a demanded place 50 (50a, 50b, 50c, 50d, 50e,... ). The fuel demand area 50 is assumed to be a place where the pelletized woody biomass fuel is planned to be used, and a biomass power plant can be cited as an example.

In addition, the fuel manufacturing place 40 is a place where the fuel demanding place 50 demands, a place for producing the pelletized woody biomass fuel itself, or a place for producing the biomass fuel which constitutes a raw material for producing the pelletized woody biomass fuel. It is supposed. As an example, the fuel production site 40 is a fuel processing plant provided in association with the palm oil industry, a processing site for processing low-quality wood generated from timber removal such as forest land remnants and thinned wood into cutting chips or firewood, lumber. Treatment plant that manufactures wood pellets or cutting chips from residual materials and sawdust generated from factories, waste treatment that manufactures wood pellets or cutting chips from wooden waste materials such as construction waste materials and used pallets generated when dismantling houses Examples include factories.

In the present specification, woody biomass means branches, leaves and other forest land residues generated during felling and lumbering of trees, bark and sawdust generated from sawmills, demolition materials for houses and roadside trees. An organic resource derived from wood such as pruned branches. Among these woody biomasses, those having a sufficient calorific value as a fuel, a small content of repellent components such as alkalis, and abundant generation amount are used as preferable woody biomass fuels.

In particular, palm empty fruit bunch (EFB), palm tree trunk (OPT), palm foliage (OPF), mesocarp fiber (MF), palm kernel shell (PKS), which is a woody biomass derived from the palm oil industry that is popular in Malaysia and Indonesia. , Palm kernel cake (PKC), palm oil factory waste liquid (POME), etc. produce a good calorific value of 4000 kcal/kg or more when dried, and PKS alone has a global capacity of about 10 million tons. It is generated and is very preferable as a biomass fuel. The calorific value in this description means the true calorific value (lower calorific value) described in JIS Z7302-2 "Waste solidified fuel-Part 2: Calorific value test method".

That is, the fuel production place 40 corresponds to the place where the above-mentioned wood biomass derived from the palm oil industry is produced, and includes a place having a function of processing this wood biomass into pellets.

When using woody biomass as fuel, it is preferable to process it into pellets. By processing into pellets, the size of the woody biomass fuel is made uniform, and the specific gravity is increased, so the calorific value is improved, and because it is easy to dry, it can be hydrated simply by leaving it in an environment with low humidity. It has favorable properties as a fuel, such as a reduced rate. Generally, the pelletized woody biomass fuel has a cylindrical shape with a diameter of about 10 mm and a length of about 50 mm, and has a calorific value of 3000 kcal/kg to 5000 kcal/kg.

The mechanical strength of the pelletized woody biomass fuel in this specification means the mechanical durability (DU) described in the "Wood pellet quality standard" of the Japan Wood Pellet Association, or JIS Z 8841 "Granulated product-strength". The mechanical strength that the pelletized woody biomass fuel should have in order to have a favorable handling property is 96.5% or more, preferably 97.% or more in terms of the mechanical durability (DU). The drop strength is 5% or more, particularly preferably 98% or more, and the drop strength is 97% or more, preferably 98% or more, particularly preferably 99% or more.

<<Step S10, Step S20>>
As described above, the distribution base 1 receives the fuel shipped from the fuel manufacturing place 40 (40a, 40b, 40c, 40d, 40e,...) In the receiving facility 3 (step S10, step S20). Step S20 corresponds to the above step (a).

It is preferable that the receiving facility 3 includes a receiving facility 3a for ocean transport and a receiving facility 3b for land transport. In FIG. 1, as an example, the fuel is transported from the fuel manufacturing locations (40a, 40b, 40c) to the distribution base 1 by the shipping means 91 such as a ship, and the fuel manufacturing locations (40d, 40e) are transported by trucks and the like. The case where the fuel is transported to the distribution base 1 by the land transporting means 92 represented by the transport vehicle of FIG.

The receiving facility 3a for shipping is composed of, for example, a port cargo handling facility installed on the coast, and is preferably equipped with a dedicated wharf. The marine transportation 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 glove bucket type, a continuous mechanical type, or a pneumatic type can be used. In particular, the glove bucket type is preferable from the viewpoint of being able to handle products of various shapes and sizes.

Note that, for example, a woodchip dedicated ship, which is an example of a ship, is generally equipped with a crane. As described above, in order to make it possible to receive the fuel conveyed by the cargo ship equipped with the crane, the shipping facility 3a for shipping may be provided with a receiving hopper provided with a conveyor.

Thereby, for example, when the fuel manufacturing locations (40a, 40b, 40c) are palm palm-derived fuel manufacturing locations such as Malaysia and Indonesia, these woody biomass fuels and the like are sent to the distribution base 1 through the shipping means. It becomes possible to accept a large amount. Further, the shipping facility 7a for shipping described below is also used as the receiving facility 3a for shipping, so that a large amount of product fuel can be shipped to the fuel demand area 50 through the ship. As a result, it is possible to reduce the physical distribution cost related to the woody biomass fuel.

Further, the receiving facility 3b for land transport is not particularly limited as long as it is a facility capable of unloading from various trucks of dump type (bounce type) or floor moving type (walking floor or slide deck), and a conveyor is attached. It is possible to effectively use the received hopper and the like. In this way, the receiving facility 3 is provided with the land receiving facility 3b, so that the wood biomass fuel such as the construction waste material generated in a small amount, which is conventionally disposed at the refuse incineration facility or the final disposal site, It can be accepted by the distribution base 1 and can contribute to the construction of a resource recycling society. Further, by using the land transportation facility 7b, which will be described later, as the land transportation receiving facility 3b, it is possible to ship the product fuel to the fuel demand area 50 located in the inland area or having a small demand amount. ..

However, the receiving facility 3 provided in the physical distribution base 1 may be provided with only one of the receiving facility 3a for ocean shipping and the receiving facility 3b for land transportation.

Here, as the fuel conveyed from the fuel manufacturing place 40, there is a case where it is a pelletized fuel (product fuel) in a state having a quality (shipment quality) that can be shipped to the demanded place as it is, It is assumed that the fuel cannot be shipped as it is because it does not satisfy the deliverable quality, and that it is a fuel that needs to be processed (received fuel). Such a difference is due to the manufacturing/processing capability of the fuel manufacturing site 40.

The above-mentioned "received fuel" refers to wood biomass fuel that has not been processed into pellet-shaped biomass fuel, and specifically, firewood such as large cracks, round firewood, small cracks, shavings, and grass, cutting chips, and screws. Chips such as cutting and crushing chips, sawdust such as sawdust and planks, bark, scraps generated during lumber, civil engineering and construction processes, and when dismantling buildings This refers to waste materials such as construction waste materials. Further, the received fuel is premised to be converted into a product fuel by being subjected to processing such as crushing and molding in step S40 described later, and therefore the shape and size are not particularly limited. Even if the biomass fuel is processed into pellets, it is included in the received fuel if it does not satisfy the shipment quality such as when the mechanical strength is extremely low.

The physical distribution base 1 has an incoming goods storage area 4 and a product storage area 6. The received product storage area 4 is a place for storing the received product fuel, and the product storage area 6 is a place for storing the product fuel. That is, when the fuel (product fuel) satisfying the deliverable quality is transported from the fuel manufacturing place 40 to the distribution base 1, this fuel is stored in the product storage area 6. On the other hand, when the fuel (accepted fuel) that does not satisfy the deliverable quality is transported from the fuel manufacturing place 40 to the distribution base 1, this fuel is stored in the received product storage area 4.

The distribution base 1 has a plurality of receiving goods storage areas 4 (4a, 4b,... ). The quality of the received fuel to be stored in the received goods storage 4 is different. That is, one received product storage space 4a corresponds to the storage place of the received fuel supply whose quality level is Qa, and another received product storage space 4b corresponds to the storage place of the received fuel supply whose quality level is Qb.

<<Step S30>>
Upon receiving the received fuel from the fuel manufacturing place 40, the distribution base 1 specifies the received product storage area 4 to be stored according to the quality of the received fuel, and also receives the received fuel in the specified received product storage 4. Transport and store (step S30). This step S30 corresponds to the step (b).

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

First, a part of the received fuel is extracted from the large amount of received fuel transported from the fuel manufacturing site (step S32). For example, as shown in FIG. 1, the distribution base 1 may include a received fuel sampler 12 for executing step S32. The received fuel sampler 12 is a sampling device for analysis/testing, and there is no particular limitation on the sampling method and the like as long as a highly representative sample can be collected. In general, as described in JIS K0060 “Industrial waste collection method” and JIS M8100 “Powder lump mixture? Sampling method general rule”, the total flow of target products falling into the outlet of conveyor or feeder A sampler that can be sampled from the width is preferably used. This step S32 corresponds to the step (b1).

Next, an analysis is performed on the extracted received fuel (step S33). For example, as shown in FIG. 1, the distribution base 1 may include the analysis equipment 11 for executing step S33.

The analysis facility 11 is not particularly limited as long as it is a device that can handle the required test/analysis items, and general-purpose test devices and analysis devices 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 facility 11 has a function of testing/analyzing the content of alkali metal, the content of chlorine, the content of water, and the calorific value of the received fuel.

The measurement of the amount of chemical components contained in the received fuel (alkali metal, chlorine, etc.) is not particularly limited as long as it is an analysis method that can obtain the desired amount of chemical components, but from the viewpoint of versatility and analysis accuracy, Alternatively, it is preferable to use an absorptiometric analysis method, an emission spectroscopic analysis method, an atomic absorption spectrometric analysis method, or an ICP emission spectroscopic analysis method for a solution obtained by completely dissolving an ashed sample with an acid. For the chlorine content, the test method of JIS Z7302-6 “Waste solidified fuel-Part 6: Total chlorine content test method” can be used. The ashing of the biomass fuel is preferably carried out at a low temperature of 600° C. or lower from the viewpoint of preventing dissipation of volatilized components such as alkali.

In addition, the method described in JIS Z7302-3 “Waste solidified fuel-Part 3: Water content test method” may be used to measure the water content (or water content) contained in the received fuel. it can. Specifically, the mass before and after heating when heating at a drying chamber temperature of 107±2° C. for 1 hour may be used. Further, instrumental analysis such as thermobalance analysis (TG) can also be used.

For the measurement of the heat value of the received fuel, for example, the method described in JIS Z7302-2 "Waste solidified fuel-Part 2: Heat value test method" can be used.

However, the analysis equipment 11 does not have to have all the analysis functions of the amount of alkali metal, the amount of chlorine, the amount of water (moisture content), and the amount of heat generation contained in the received fuel, and at least of these, It only needs to have one or more analysis functions.

The method of transporting the received fuel extracted by the received fuel sampler 12 to the installation location of the analysis facility 11 is not particularly limited, but an air pipe system or the like capable of automatically transporting the sample is preferable. Used for.

Next, the quality of the target received fuel is specified based on the result of analysis by the analysis facility 11 (step S34). Step S34 corresponds to step (b3).

As a method of specifying the quality of the received fuel, it is possible to use any quality item and any number of levels in each quality item. For example, when the heat amount, the water amount, and the alkali content are selected, the heat amount and the water amount that can be processed relatively easily are taken into consideration in consideration of the difficulty of the processing performed in step S40 described below. The two items of quantity were classified into two levels, large and small, according to specific thresholds, and the alkali content, which was more difficult to process, was classified into three levels, large, medium and small, totaling 12 types (= 2 x 2 x 3). A method of classifying can be adopted. The chlorine content may be included in the classification item.

Next, based on the quality of the received fuel specified in step S34, the received goods storage 4 which is the storage destination of the received fuel is selectively selected from the received goods storage (4a, 4b,... ). It is specified (step S35). As described above, the quality of the received fuel to be stored is different in each of the received goods storage areas 4. The information regarding the quality of the received product fuel assigned to each of the received product storage areas 4 may be stored in advance in a storage unit of an information processing device (not shown) or on paper. On the basis of this stored information, the received goods storage space 4 where the received goods fuel is stored is specified. In addition, when the quality of the received fuel specified in step S34 satisfies the quality that can be shipped, the fuel may be stored in a predetermined product storage space 6, or one storage space of the received storage space 4 (for example, the received storage space). The product storage space 4a) may also be used as the product storage space 6.

Then, the received fuel is transferred to and stored in the specified received goods storage 4 (step S36). In addition, when the received fuel is transferred from the receiving facility 3 to the received storage 4, the fuel (received fuel/product fuel) in the distribution base 1 is transported by heavy equipment such as a wheel loader or a bulldozer, or pneumatic pressure. Although feeding can be used, it is preferable to use conveyors such as a belt conveyor and a screw conveyor from the viewpoints of efficiency, work safety, prevention of scattering of woody biomass fuel, equipment cost, and the like. Since chips and the like are likely to cause a clogging condition called bridging, it is preferable to devise a device such as a baffle plate or the like to prevent clogging at a portion having a narrowed path.

It should be noted that the receiving goods storage 4 (4a, 4b,...) Is a facility that can store the received wood biomass fuel, which is a wood biomass fuel, without causing rain and wetting, and has no trouble in receiving and unloading goods. There is no particular limitation, and buildings with roofs and silos can be effectively used. Further, from the viewpoint of preventing spontaneous ignition during storage as well as preventing water wetting, for example, a drying gas can be ventilated into the storage space or a pile of woody biomass fuel as described in Japanese Patent No. 6381836. More preferred is a storage facility equipped with the turning device of. When a building with a roof is used as the receiving goods storage 4, if it is possible to manage the receiving goods fuel classified by quality so as not to mix with each other, it is possible to store a plurality of receiving goods fuel in one building. it can.

Note that some fuel manufacturing locations 40 may have a function of analyzing the quality of the fuel (received fuel or product fuel) shipped to the distribution base 1. At this time, the fuel manufacturing location 40 Information about the quality of the transported fuel may be notified to the distribution base 1. In this case, based on the information related to the quality of the received fuel that is notified from the fuel manufacturing place 40, the received product storage 4 that is the storage destination of the received fuel is specified, and the specified received product storage 4 is specified. The received fuel may be stored in (steps S35, S36). In this case, it is not always necessary to perform the analysis processing on the received fuel in the distribution base 1.

<<Step S40>>
Next, a processing process is performed on the received product fuel stored in the received product storage 4 and a quality improvement process is performed to generate a fuel (product fuel) that satisfies the shipment quality. This step S40 corresponds to the step (c). As shown in FIG. 1, the distribution base 1 is equipped with a processing facility 5 for executing this step S40.

For example, for a received fuel with a small calorific value, a mixing process with another received fuel with a large calorific value is executed. A drying process is performed on the received fuel having a large water content. For a received fuel having a high alkali content, a mixing process with another received fuel having a low alkali content is executed. The received fuel that has not been processed into pellets is subjected to foreign matter removal processing, crushing processing and/or classification processing, and then pelletized molding processing.

That is, the processing includes foreign material removal processing, mixing processing, crushing processing, drying processing, classification processing, and molding processing. In step S40, all of 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 processing equipment 5. In the example shown in FIG. 4, the processing equipment 5 includes a foreign matter removing equipment 51, a mixing equipment 52, a crushing equipment 53, a drying equipment 54, a classification equipment 55, and a molding equipment 56.

The foreign matter removal facility 51 is a facility for removing foreign matter such as hard wood chips such as tree knots, debris, and metals contained in the received fuel that is a non-pellet woody biomass fuel, and the foreign matter removal process described above. Is a facility for executing. The foreign matter removing equipment 51 is not limited to the device mode and the separation principle as long as it has the above-mentioned function, and a sieve, a gravity type classifier, a centrifugal type classifier, a wind sorter, a magnetic sorter, or the like, or One or more devices can be used in combination.

The mixing facility 52 is a facility for dry-mixing the received fuels, and is a facility for performing the above-mentioned mixing process. The mixing equipment 52 is not limited to an apparatus form as long as it has the above-mentioned functions, and is a heavy-duty machine such as a wheel loader, a bladed mixer having a defibration effect, or a rotary sieve having a classification function of a classification equipment 55 described later. Alternatively, a twin-screw kneading extruder having a molding function of the molding equipment 56 described later can be effectively used.

The crushing facility 53 is a facility for crushing, crushing, and refining the received fuel, which has a problem in mechanical strength, size, etc., and crushing it to a diameter of the die small hole of the molding facility 56 or less. It is equipment for executing processing. The crushing equipment 53 is not limited to the apparatus mode and the crushing principle as long as it has the above-mentioned functions, and includes a roller mill, a ball mill, a pusher type crusher (single axis and twin axis), a knife type (chipper type), a hammer type (shredder). Type) or a hammer knife type (chipper shredder type) wood chip making machine (wood chipper), a hammer mill, or the like, or one or more devices can be used continuously.

The drying facility 54 is a facility for drying the received fuel, and is a facility for performing the above-mentioned drying process. The drying equipment 54 is not limited to the apparatus mode or the drying principle as long as it has the above-mentioned functions, and is not limited to a warm air spraying device, a box dryer, a band dryer, a band fluidized bed dryer, a rotary dryer, a wedge style dryer. In addition to the dedicated equipment such as the above, a place where the temperature can be controlled by using exhaust heat or the like, or a place where only natural drying such as sun drying or indoor drying can be performed may be used. Further, a forced crushing drier having an crushing function of the crushing equipment 53, such as an arm type impact crushing drier, a hammer type impact crushing drier or a chain type impact crushing drier, may be used.

The processing temperature in the drying process can be 175°C or lower. As a result, the temperature of the woody biomass fuel becomes sufficiently high during the drying process (for example, 80° C. or higher), so that even if microorganisms are present in the woody biomass fuel, they can be killed. To be done. On the other hand, when the temperature of the woody biomass fuel exceeds 175° C., the biomass fuel accumulates heat, which may cause thermal runaway and ignite. Therefore, the drying treatment temperature is preferably 80° C. or higher and 175° C. or lower.

The classification equipment 55 is not particularly limited as long as it is a dry equipment capable of classifying the received fuel according to size, and a vibration type or rotary type sieve can be preferably used.

The molding facility 56 molds the received fuel itself received by the receiving facility 3 or the small size or crushed product of the received fuel obtained through the crushing facility 53 and/or the classifying facility 55 to form pellets of a predetermined size. It is a facility for making woody biomass fuel. The molding equipment 56 is generally composed of a die having a large number of cylindrical small holes and a compression roller, and crushed chips and the like are pushed into the small holes by the compression roller and molded into pellets. .. Depending on the shape of the die, it is classified into a ring die method and a flat die method, but either method can be used.

For example, even if the fuel conveyed from the fuel production site 40 is a pelletized wood biomass fuel, if the water content exceeds 15 mass%, or if the mechanical strength decreases due to water wetting, etc. , There is a case that the shipping quality is not satisfied. That is, it is assumed that the pelletized woody biomass fuel conveyed from the fuel manufacturing site 40 is recognized as the received fuel, not the product fuel.

For example, regarding the pelletized woody biomass fuel, when the water content is higher than 15% by mass, it may be treated as the received fuel and the drying process may be executed in this step S40. If the water content of the pelletized woody biomass fuel is 15% by mass or less, the pelletized woody biomass fuel has sufficient mechanical strength to withstand mechanical impacts such as transportation, and can retain its own shape. There is no problem in handling properties. Therefore, the drying treatment does not necessarily have to be performed on the pelletized woody biomass fuel having a water content of 15% by mass or less.

In addition, the received fuel, which is a pelletized wood biomass fuel whose mechanical strength has decreased due to water wetting, etc., may be crushed and then re-molded into pellets. For example, in the case of pelletized woody biomass fuel, when the water content exceeds 40 mass %, a collapse phenomenon due to swelling occurs, and it becomes difficult for the pellets to maintain the shape even if the above-mentioned drying treatment is performed. Therefore, even if the biomass fuel in such a state is dried to reduce the water content, a biomass fuel decomposed into powder or short fibers is obtained, and it may be difficult to recover the handling property. Therefore, when the water content of the pelletized woody biomass fuel is 40% by mass or more, once the pelletized woody biomass fuel is decomposed into short fibers by a crushing treatment, etc., and then dried, and then molded into pellets again. Good.

As shown in FIG. 5, the distribution base 1 has a waste white clay storage 61 for receiving the waste white clay conveyed from the waste white clay generation place 60 (60a, 60b,...) And storing the received white clay. In this case, the wood biomass fuel and the waste clay may be mixed in the mixing process included in step S40. Examples of the waste clay generation location 60 include a manufacturing factory for fats and oils such as palm oil and a manufacturing factory for lubricating oil and petroleum products. In this case, the distribution method of the pelletized woody biomass fuel according to the present invention includes a step S70 of storing the waste white clay conveyed from the waste white clay generation place 60. This step S70 corresponds to the step (f).

More specifically, the step S70 is, as shown in FIG. 6, a step S71 of shipping the waste white clay from the waste white clay generating place 60, a step S72 of receiving the waste white clay at the distribution base 1, and a step of receiving the received white clay. It has a step S73 of storing in the storage 61.
accept

Waste clay that can be mixed and used with woody biomass fuel is mineral oil or vegetable oil, which is produced by deodorizing or decolorizing acid clay or activated clay, and is used clay that contains oil and fat, It has a calorific value of 3000 kcal/kg or more. When the woody biomass fuel and the waste clay are mixed, the mixing ratio of the woody biomass fuel (A) and the waste clay (B) is preferably A:B (mass ratio) of 98:2 to 84:16. When the mixing ratio of the waste white clay (B) is less than 2% by mass or more than 16% by mass, the pelletized woody biomass fuel may not have sufficient mechanical strength.

As the equipment for mixing the woody biomass fuel and the waste clay, the mixing equipment 52 may have a configuration in which only a stirring blade is provided, but a stirring blade is additionally provided, and the mixing container itself is also provided. It is more preferable to use a rotating structure. By rotating the mixing container itself, a viscous material such as waste clay and a material having a low bulk density such as woody biomass fuel can be mixed well. As an example of a mixer having a structure in which the container itself is also rotated, there is an intensive mixer manufactured by Eirich.

<<Step S50>>
Next, with respect to the product fuel generated in step S40 and the product fuel received in step S20, the product storage space 6 that is the storage location is specified according to the quality, and the product fuel is stored in the specified product storage space 6. Are transported and stored (step S50). This step S50 corresponds to the step (d).

FIG. 7 is a flowchart showing an example of the flow of processing included in step S50. In the example shown in FIG. 7, step S50 is configured to include each processing of step S52, step S53, step S54, step S55, and step S56.

First, some product fuels are extracted from a large amount of product fuels for which storage destinations are to be determined (step S52). This step S52 corresponds to the step (d1).

For example, as shown in FIG. 1, the distribution base 1 may include the product fuel sampler 13 for executing step S52. The product fuel sampler 13 may have the same configuration as the received product fuel sampler 12 described above. The received fuel sampler 12 may also serve as the product fuel sampler 13.

Next, the extracted product fuel is analyzed (step S53). This step S53 corresponds to the step (d2). In the example shown in FIG. 1, the case where the product fuel extracted by the product fuel sampler 13 is analyzed by the analysis equipment 11 similar to step S33 is illustrated. However, the distribution base 1 may be provided with a dedicated analytical facility 11 to be executed in step S53, in addition to the analytical facility 11 used in step S33.

Also in this step S53, the amount of alkali metal contained, the amount of chlorine contained, the amount of water contained, and the calorific value of the product fuel may be tested/analyzed similarly to step S33 described above. However, in the case of the product fuel generated through the processing according to step S40, for example, when all the product fuels can satisfy the quality level regarding the moisture content by performing the drying process. There is. In this case, in this step S53, for example, the analysis of the water content may be omitted, and only the two items of the calorific value and the alkali metal content may be analyzed.

Next, the quality of the target product fuel is specified based on the result analyzed by the analysis facility 11 (step S54). Step S54 corresponds to step (d3).

As a method of identifying the quality of the product fuel, similar to the method of identifying the quality of the received fuel described in step S34, any quality item and any number of levels in each quality item may be used. However, as described above, since it is possible that all product fuels satisfy the standard regarding the water content, it is possible to limit the water content to, for example, two items such as the calorific value and the alkali content. Then, for these limited quality items, a quality level according to the quality demanded by the consumer side may be provided, and in many cases, most quality items can be set to two levels, large and small. Therefore, when the two items of the calorific value and the alkali content are the quality items to be managed for the product, a method of classifying the product fuel into four types (=2×2) can be adopted as a whole.

Next, based on the quality of the product fuel specified in step S54, the product storage space 6 that is the storage destination of the product fuel is selectively specified from among the product storage spaces (6a, 6b,...) (step). S55). As described above, the quality of the product fuel to be stored is different in each product storage area 6. The information regarding the quality of the product fuel assigned to each product storage space 6 may be stored in advance in a storage unit of an information processing device (not shown) or on paper. Based on the stored information, the product storage space 6 where the product fuel is stored is specified.

Then, the product fuel is transported to and stored in the specified product storage space 6 (step S56). The product storage area 6 (6a, 6b,...) Is also stored in the same manner as the received product storage area 4 (4a, 4b,...) Without receiving rain or the like on the received product fuel, which is the wood biomass fuel that has been received. The facility is not particularly limited as long as it is capable of receiving and unloading, and a roofed building or silo can be effectively used.

<<Step S60>>
Next, the product fuel stored in the product storage area 6 is shipped to the fuel demand area 50 (50a, 50b, 50c,... ). This step S60 corresponds to the step (e).

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

Information about the quality (demand quality) desired by each fuel demanding place 50 is given from each fuel demanding place 50 (50a, 50b, 50c,... ). In the distribution base 1, first, the product storage space 6 in which the product fuel satisfying this demand quality is stored is specified (step S61). This step S61 corresponds to the step (e1).

Next, a part of the product fuel is extracted from the large amount of product fuel stored in the specified product storage area 6 (step S62). This step S62 corresponds to the step (e3).

For example, as shown in FIG. 1, the physical distribution base 1 may include a sampler 14 for shipping products for executing step S62. This shipping product sampler 14 can have the same configuration as the received product fuel sampler 12 and the product fuel sampler 13 described above. The received product fuel sampler 12 and/or the product fuel sampler 13 may also serve as the shipped product sampler 14.

Next, the extracted product fuel is analyzed (step S63). This step S53 corresponds to the step (e4). In the example shown in FIG. 1, the case where the product fuel extracted by the sampler 14 for shipping products is analyzed by the analysis equipment 11 similar to step S33 is illustrated. However, the distribution base 1 may be provided with a dedicated analysis facility 11 to be executed in step S63, in addition to the analysis facility 11 used in steps S33 and/or S53.

Next, based on the result analyzed by the analysis facility 11, the quality to which the product fuel extracted by the shipping sampler 14 belongs is specified, and whether the specified quality satisfies the demand quality is confirmed. (Step S64). This step S64 corresponds to the step (e4) and the step (e5). If the target product fuel does not meet the demand quality, the process may return to step S61 to specify another product storage space 6 in which the target product fuel is stored again, or step S40. Alternatively, the received fuel may be processed to produce a product fuel that satisfies the demand quality.

When it is confirmed in step S64 that the target product fuel satisfies the demand quality, a large amount of product fuel stored in the product storage area 6 is transported to the shipping facility 7 (step S65).

The shipping facility 7 preferably includes a shipping facility 5a for ocean shipping and a shipping facility 5b for land transportation. The shipping facility 5a for shipping by sea is not particularly limited as long as it is a facility such as a ship loader for bulk loading, a crane or a hoist for containers or flexible containers, and the like, which is capable of shipping according to the packing form. Further, the shipping facility 5b for land transportation is not particularly limited as long as it is a facility such as a hopper for loading a bulk truck, a forklift handling a flexible container, or the like and capable of shipping according to the type of package.

However, the shipping facility 7 provided in the distribution base 1 may be provided with only one of the shipping facility 5a for ocean shipping and the shipping facility 5b for land transportation.

Then, the product fuel is shipped from the shipping facility 5a for shipping to the fuel demand area 50 (50a, 50b, 50c) by the shipping means 93 such as a ship, and is transported from the shipping facility 5b for land transportation to a transportation vehicle such as a truck. The fuel is shipped to the fuel demand area 50 (50d, 50e) by the representative land transportation means 94 (step S66). This step S66 corresponds to the step (e2).

Note that the properties of the pelletized woody biomass fuel are unlikely to change during storage unless water gets wet. The quality of the product fuel stored in the product storage area 6 is analyzed and specified when the product storage area 6 of the storage destination is determined in step S50. Therefore, in many cases, the product fuel stored in the product storage area 6 still maintains the quality associated with the product storage area 6 in which the product fuel is stored, even immediately before the shipment. From this point of view, steps S62 and S63 may be omitted, and in step S64, it may be possible to simply confirm whether or not the quality of the product fuel associated with the product storage area 6 of the storage destination satisfies the demand quality. ..

Note that the above-described step S30 may include step S31 of performing processing on the received fuel in advance (see FIG. 9). For example, as shown in FIG. 1, the distribution base 1 may be provided with a pre-processing facility 8 for executing this step S30.

FIG. 10 is a block diagram schematically showing an example of the configuration of the pre-processing equipment 8. In the example shown in FIG. 10, the pre-processing equipment 8 includes a foreign matter removing equipment 81, a crushing equipment 83, a drying equipment 84, and a classification equipment 85. For example, if the received fuel conveyed from the fuel manufacturing site 40 is a non-pellet wood biomass fuel and a large amount of foreign substances are mixed, or if the sizes are different, etc., it is stored as it is in step S30. In the case where it is difficult to specify the received goods storage area 4 in advance, necessary processing is performed on the received goods fuel in the preprocessing equipment 8. The preprocessing facility 8 does not have to include all of the foreign matter removing facility 81, the crushing facility 83, the drying facility 84, and the classifying facility 85, and may include at least one type of facility. I do not care.

The foreign matter removing equipment 81 is configured with the same equipment as the foreign matter removing equipment 51 included in the processing equipment 5. The foreign matter removing equipment 51 may also serve as the foreign matter removing equipment 81.

The crushing equipment 83 is composed of the same equipment as the crushing equipment 53 included in the processing equipment 5. The crushing equipment 53 may also serve as the crushing equipment 83.

The drying equipment 84 is composed of the same equipment as the drying equipment 54 included in the processing equipment 5. The drying equipment 54 may also serve as the drying equipment 84.

The classification facility 85 is configured with the same equipment as the classification facility 55 included in the processing facility 5. The classification facility 55 may also serve as the classification facility 85.

It should be noted that the amount of received fuel that can be stored in the received goods storage 4 (4a, 4b, 4c,...) Of the distribution base 1 and the amount of product fuel that can be stored in the product storage 6 (6a, 6b, 6c,...) The total of the amount and the amount is preferably 15,000 t or more, more preferably 30,000 t or more, and particularly preferably 60,000 t or more. Since the distribution base 1 has such a storage capacity, for example, required fuel for several weeks in a 75 MW class biomass power generation boiler can be stocked.
