Description

The present invention is a transport system for transporting solid fuel discharged from a storage device to a fuel combustion device, and more specifically, a fossil fuel alternative fuel or fossil fuel which is a solid substance discharged from a storage device is used as a fuel combustion device. The present invention relates to a transport system including a transport path for transporting to and a device constituting the transport route.

A transfer system for transporting fossil fuel alternative fuel or fossil fuel, which is a solid substance discharged from the storage device, to the fuel combustion device is adopted as a part of the equipment in which the fuel combustion device is incorporated.

An example thereof is the transport system shown in FIG. 21 (Patent Document 1). This transport system transports the biomass 521 discharged from the biomass storage facility 520 to the biomass crusher 523 via the biomass hopper 522, and transports the crushed material into the furnace body 531 and the coal storage facility. The coal 525 discharged from 524 is transported to the coal crusher 528 via the coal hopper 526, and the crushed coal is transported into the furnace body 531 and the coal 525 discharged from the coal storage facility 524. , It is equipped with a transport path that transports the crushed coal to the coal crusher 529 via the coal hopper 527 and transports the crushed material into the furnace body 531 of the boiler reactor equipment 530.

Another example is the transport system shown in FIG. 22 (Patent Document 2). In this transfer system, the biomass pellet 611 discharged from the biomass pellet storage facility 615 is moistened with the water 612 discharged from the water application means 613, and then transferred to the hopper 616 as the wet biomass pellet 611A, and the hopper. After passing through 616 and coarse crushing means 614, it is transported as coarse crushed biomass pellets 611B toward the crushing raw material bunker 619, and after passing through the crushing raw material bunker 619, supply pipe 623 and fine crushing means 614B, fine powder biomass pellets. The 611C is equipped with a transport path for transporting to the boiler furnace 626, and in addition, the coal 630 discharged from the coal storage facility 631 is directed to the position Q on the transport path of the biomass pellets 611, 611A, 611B, 611C. It also has a transport route (coal supply line 633). The main portion of the transport path of the biomass pellets 611, 611A, 611B, and 611C is composed of the first transport means 617, the second transport means 618, and the third transport means 627, and the position Q is the second transport. This is the position where coal 630 is put onto the coarsely crushed biomass pellet 611B transported by means 618.

Yet another example is the transport system shown in FIG. 23 (Patent Document 3). This transfer system constitutes a part of the fuel supply device 700 that supplies multiple types of co-firing fuel to the gasification fuel reactor facility. For coal transfer, the coal mill 710, dust collector 720, and lower feeder 750. Two routes, one is a transfer route to the gasification fuel reactor via the storage bin 770, and the other is a transfer route to the gasification fuel reactor via the coal mill 715, the dust collector 725, the lower feeder 755 and the storage bin 770. For the transportation of biomass, after passing through the biomass crusher 730 and the dust collector 740 in this order, the transportation route to the gasification fuel furnace via the upper feeder 760, the lower feeder 750 and the storage bin 770 in that order, and the upper stage It has two transport routes to the gasification fuel reactor via the feeder 765, the lower feeder 755, and the storage bin 770 in that order. In the fuel supply device 700, under the control of the control device 790, the biomass and the coal are crushed by individual crushers, and then the biomass fine particles and the coal fine particles are used so that the desired co-firing rate of the biomass can be obtained. The mixing ratio of the coal is appropriately adjusted and stored in the storage bin 770. Therefore, it can be said that this transfer system transfers a plurality of types of co-firing fuel to the gasification fuel furnace facility via the storage bin 770.

However, in the transport system shown in FIG. 21, since only one type of biomass 521 is discharged from the biomass hopper 522 and transported toward the boiler main body 531, there is only one transport route for transporting the biomass 521. Even in the transport system shown in FIG. 22, the biomass pellets 611, 611A, 611B, and 611C discharged from the hopper 616 and transported toward the boiler furnace 626 are only one type, although there is a difference in the presence or absence of wetting due to moisture. There is only one transport route for transporting it.

Further, in the transport system shown in FIG. 21, although there are two transport routes for the coal 525 discharged from the coal hoppers 526 and 527 and transported toward the boiler main body 531, a plurality of types of co-firing fuel are transported to the boiler main body. There is no place where the transportation route of any coal 525 is the same as the transportation route of biomass 521, and the equipment constituting those transportation routes is not the same (it does not become a common equipment). Therefore, the biomass 521 and the coal 525 do not mix with each other until they reach the boiler body 531 after being discharged from their respective hoppers. Here, the "type" in a plurality of types of co-firing fuels means individual sets that are grouped from the viewpoint of the calorific value per unit weight (hereinafter, may be referred to as "energy density"), and in that sense, "Multiple types of co-firing fuels" may be read as a plurality of co-firing fuels having different energy densities.

In the transfer system shown in FIG. 22, the transfer paths of the biomass pellets 611, 611A, 611B, and 611C and the coal supply line 633 have the position Q as a connection point, and the transfer paths are the same downstream from the position Q. The constituent devices are the same. However, since the amount of coal 630 charged onto the biomass pellet 611B at position Q is usually large, the second transport means 618 has a transport force (conveys heavy objects) possessed by the transport means constituting the coal supply line 633. Compared to the capacity), it must have a stronger transport capacity, and it is also necessary to strengthen measures against dust rising from the coal 630, so there is a problem that the equipment cost will be higher as a whole. ..

According to the transfer system shown in FIG. 23, a plurality of types of co-firing fuel can be transported to the gasification fuel furnace facility. However, this transport system requires two transport routes, a total of four transport routes, to reach the lower feeders 750 and 755, where one of the biomass and coal is mixed and agitated with the other, and they are mutually exclusive. There are no places that are the same, and the devices that make up those transport routes are not the same. Then, one crusher for crushing biomass, at least two crushers for crushing coal, and two feeders 750 and 755 for mixing and stirring biomass fine powder and coal fine powder, for a total of crushing and mixing. The equipment configuration requires at least five processing equipment to be performed. Therefore, this transfer system cannot be said to have a simple configuration, and has a problem that the equipment cost becomes higher.

The present invention has been made in view of the above problems, and the transportation of a plurality of types of fossil fuel alternative fuels can be performed in a simpler structure as a whole and in a configuration capable of avoiding an increase in equipment cost.

When the transported object contains a plurality of compositions, the plurality of compositions are mixed at the same time as the crushing of the transported object. Therefore, the “processing device” for crushing the transported object is a “processing device” for the transported object. It also serves as a "processing device" for mixing, and therefore corresponds to a "processing device" for at least crushing and / or mixing the conveyed object.

The "processing device" may be an device that performs other processing in addition to crushing and / or mixing. In addition, the substance to be mixed with the transported object means the substance when the explanation is limited to a specific substance, and when there is no such explanation, the result of the mixing is significant.

Hereinafter, the effects of the present invention will be described for each form, but a form in which a plurality of effects are listed shall exhibit at least one of the plurality of effects.

According to the first aspect of the present invention, a part of the device constituting each transport path is shared within the range where a part of the first transport path and a part of the second transport path are the same route. Therefore, it is possible to make a transport system that transports a plurality of types of fossil fuel alternative fuels having different energy densities to a fuel combustion device as a whole, which is simpler as a whole and can avoid an increase in equipment cost. ..

According to the second embodiment of the present invention, when the amount of the contained material in each of the first storage device and the second storage device is reduced, the first fossil fuel alternative fuel and the second fossil fuel alternative fuel are used. Since it can be replenished by any of the above, the replenishment of the fossil fuel alternative fuel, which needs to be transported to the fuel combustion device, to each of the first storage device and the second storage device is interrupted or delayed. You can do it without letting it.

The third embodiment of the present invention is a specific example of the first embodiment. According to this third embodiment, a part of the first transport path from the first storage device to the first processing device and the second from the second storage device to the second processing device. The effect of the first form can be obtained as long as a part of the second transport path is the same path.

According to the fourth aspect of the present invention, even if the transfer system further includes a third transfer path and a third transfer device constituting the third transfer path, the third transfer device crushes fossil fuel. A first processing device and / or a second processing that grinds and / or mixes a first fossil fuel alternative fuel or a second fossil fuel alternative fuel without having to equip itself with a processing device for mixing and / or mixing. Since the device is used as a substitute, it is possible to suppress the complexity of the transport system and the increase in equipment cost.

According to the fifth aspect of the present invention, each transport route is within a range in which a part of the first transport route and / or a part of the second transport route and a part of the third transport route are the same route. Since some of the devices that make up the fuel can be shared, a transport system that transports multiple types of fossil fuel alternative fuels and fossil fuels with different energy densities to the fuel combustion device as a whole is simpler, and by extension, equipment costs. It is possible to make a configuration that can avoid the increase in the cost.

When transporting fossil fuel and fossil fuel substitute fuel in a mixed state and crushing them, for example, if the amount of fossil fuel substitute fuel is large, the total amount of objects to be transported and crushed materials will increase, so for transporting fossil fuels. It is necessary to increase the size and performance of the transport device and the crusher for crushing it, which in turn leads to an increase in equipment cost. This problem becomes particularly remarkable when the fossil fuel alternative fuel is more difficult to crush than the fossil fuel. On the other hand, according to the sixth embodiment of the present invention, the transported object and the workpiece are fossil fuel and a small amount (for example, fossil fuel and fossil fuel alternative fuel) which directly fall on the fossil fuel are coal and fossil fuel, respectively. If the wood pellet is a wood pellet, the amount of the wood pellet is 0.069 or less when the fuel is 1 based on the weight, and if the wood pellet is a black pellet, the fuel is black when the fuel is 1 based on the weight. Since the pellets remain in a mixed state with the fossil fuel substitute fuel (in an amount of 0.38 or less), a transport device for transporting the fossil fuel and a processing device for crushing and / or mixing the fossil fuel are used. a) It can be used to the extent that it can be used on a smaller scale or with higher performance for those devices, or (b) if the performance of the original device can be afforded (more specifically). In the case of a transport device having originally high transport performance or a processing device having originally high machining performance), the device or those devices can be used as they are, and it is possible to suppress an increase in equipment cost. .. This effect is for transporting a co-firing fuel composed of fossil fuel and fossil fuel alternative fuel to a transport system equipped with an existing transport path for transporting fossil fuel and an existing transport device constituting the transport route. It is useful because it makes it possible to suppress the increase in scale and cost of construction in the construction of changing to a transportation system equipped with a transportation route and the equipment constituting the transportation route.

The amount of fossil fuel alternative fuel that falls directly on the fossil fuel can be any amount, except in the case where the effect that the sixth embodiment of the present invention should exert is not obtained at all, but in many cases, the fossil fuel is concerned. The weight ratio, calorific value ratio, etc. between the fossil fuel and the fossil fuel alternative fuel are adjusted to be constant. One guideline is that when the fossil fuel is coal and the fossil fuel alternative fuel is wood pellets, the amount of wood pellets is 0.05 when coal is set to 1 based on the calorific value per unit weight. Adjust to the following (when the wood pellet is black pellet, the amount of black pellet is 0.3 or less). With this amount of wood pellets, it can be said that the co-firing rate of coal and wood pellets is relatively high, but the amount is sufficiently small with respect to coal, and a transport device for transporting coal and crushing for crushing coal. The device can be used as it is, or after being made smaller and larger in size and higher in performance.

Further, according to the sixth embodiment of the present invention, since the fossil fuel substitute fuel directly falls on the fossil fuel, it is easy to adjust the distribution of the fossil fuel substitute fuel to the fossil fuel so as to be uniform, and the fuel substitute fuel continues. It is relatively easy to maintain the quality of the fuel for co-firing, which is composed of fossil fuel and fossil fuel substitute fuel, which is crushed and / or mixed, and thus produced by it.

When the processing device for crushing and / or mixing the transported object is continuously operated, a temporary storage means for storing the transported object in advance is provided at a position on the upstream side of the processing device. In many cases, the transported object is continuously charged into the processing apparatus from the temporary storage means. On the other hand, when the amount of fossil fuel substitute fuel that directly falls on the transported fossil fuel is small, the relatively large amount of fossil fuel is continuously charged into the processing equipment, while it is relative. It is no longer necessary to provide a temporary storage means for storing a large amount of fossil fuel alternative fuel, which is relatively small in quantity, in advance. Therefore, in that case, according to the sixth embodiment of the present invention, the temporary storage means for storing the fossil fuel alternative fuel in advance can be omitted or the capacity can be made small, and the equipment cost can be increased. Can be further suppressed.

According to the seventh aspect of the present invention, the decrease in the amount of fossil fuel substitute fuel discharged from either the storage device S1 or the storage device S2 is compensated by the fossil fuel substitute fuel discharged from the other. Fluctuations in the amount of the fossil fuel alternative fuel that falls directly on the fossil fuel transported along the third transport route or by the third transport device can be suppressed to zero or minimal, and thus the fossil fuel. It can be carried out without interrupting or delaying the transfer to the downstream side of the alternative fuel.

Further, according to the seventh form, since the fossil fuel alternative fuel directly falls on the fossil fuel, the effect produced by the sixth form can be obtained.

The meaning of "supplementing the decrease in the amount of fossil fuel substitute fuel discharged from one side with the fossil fuel substitute fuel discharged from the other side" of the storage device S1 and the storage device S2 is "along the third transport route". Or to suppress fluctuations in the amount of fossil fuel substitute fuel that directly falls on the fossil fuel transported by the third transfer device to zero, minimum, or within a certain range "(hereinafter referred to as" control purpose ". There are no particular restrictions as long as it can achieve (there is).

In the case of "supplementing the decrease in the amount of fossil fuel substitute fuel discharged from one side with the fossil fuel substitute fuel discharged from the other side", the fossil fuel substitute fuel discharged from the other side is the fossil fuel discharged from the other side. Time to reach the discharge position of the alternative fuel, time to reach the discharge position of the fossil fuel alternative fuel discharged from the other, emission control means provided by the other (the other controls the emission amount) When using a bridge prevention means or feeder for this purpose, it is necessary to consider multiple factors such as the behavioral characteristics of the bridge prevention means and the feeder), but how to compensate for the decrease is As long as the control objective can be achieved, there are no particular restrictions, and various designs and selections can be made.

According to the eighth embodiment of the present invention, a co-firing fuel (hereinafter referred to as "first co-firing fuel") and a second fossil having a composition of a first fossil fuel alternative fuel and a first fossil fuel. Either one of the co-firing fuel (hereinafter referred to as "second co-firing fuel") composed of the fuel substitute fuel and the second fossil fuel can be selectively produced. In addition, a part of the first transport path from the first storage device to the first crushing device and a part of the second transport path from the second storage device to the second crushing device. The effect produced by the first form can be obtained within the range where and is the same route. Furthermore, the crushing of the second fossil fuel and the second fossil fuel alternative fuel for producing the second co-firing fuel, and the fossil fuel (first fossil fuel) that composes the first co-firing fuel The same device (second crushing device) can be used for the crushing of the second fossil fuel to be prepared, and therefore the increase in equipment cost can be suppressed.

According to the ninth aspect of the present invention, when one of the first co-firing fuel and the second co-firing fuel is selectively produced, it is along a third transport path or a third transport device. The fossil fuel (first fossil fuel) that composes the first co-firing fuel and the fossil fuel (second fossil) that composes the second co-firing fuel by the fossil fuel (second fossil fuel) transported by It can cover both fuel). Further, since the routes R1 and R2 are both a part of the third transport route and pass through the same device (second crushing device), the effect produced by the fourth mode can be obtained. Further, since the route R1 is the same route as a part of the second transport route and the part of the route R2 is the same route as a part of the first transport route, the route R2 is within the range of the same route. , The effect produced by the fifth form can be obtained.

According to the tenth embodiment of the present invention, since the fossil fuel alternative fuel directly falls on the fossil fuel, the effect produced by the sixth embodiment can be obtained.

According to the eleventh embodiment of the present invention, the effect produced by the seventh embodiment can be obtained.

When a part or all of the outer shape of the object to be transported collapses and becomes powder, (a) it enters the gap of the transport device and causes malfunction, (b) it becomes clogged in the crusher, and eventually causes malfunction, (c) dust. Problems such as the need to strengthen countermeasures arise. Then, the wood pellets that are swollen or moistened by moisture have a part or all of their outer shape collapsed and easily pulverized, and the pulverization is accelerated by the vibration or impact received in the transport process, which causes the problem. .. On the other hand, according to the twelfth aspect of the present invention, the wood pellets to be transported are neither swollen nor wet, so that the problem does not occur.

In this twelfth form, when the fossil fuel alternative fuel directly falls on the fossil fuel (for example, the sixth, seventh, tenth and eleventh forms), the fossil fuel alternative fuel is used. Especially useful when it is a wood pellet. This is because if the wood pallet is moist or swollen or moistened by water, it will be difficult to evenly land the wood pallet on the fossil fuel, thereby, for example, subsequent grinding and / or According to this twelfth form, the wood that directly falls on the fossil fuel may cause problems such as hindrance to mixing and deterioration of the quality of the fuel for mixed combustion produced by crushing and / or mixing. This is because the pellets are neither swollen nor wet, so the problem does not occur.

When crushing coal and wood pellets in a mixed state, there is a problem in the crusher due to the difference in crushability between coal and wood pellets (usually, wood pellets are more difficult to crush than coal). For example, malfunction of the crushing device due to clogging of wood pellets) is likely to occur, and the larger the amount of wood pellets with respect to coal, the more likely it is to occur. As a countermeasure, increasing the size and performance of the crusher will lead to an increase in equipment costs. On the other hand, if (a) the amount of wood pellets is 0.05 or less when coal is 1 based on the energy density, as in the thirteenth embodiment of the present invention, or (b). ) As in the fourteenth form of the present invention, if the wood pellet is a black pellet of 0.3 or less when coal is set to 1 based on the energy density, the amount of wood pellet with respect to coal is small. , The occurrence of the above-mentioned problems can be suppressed.

When a large amount of substance is directly dropped on the coal, there is a concern that dust will be generated from the side of the dropped coal and that the transport device to which the substance is discharged will be damaged by the drop impact of the substance. Since the amount of wood pellets that fall directly on the coal is small (for example, 0.069 or less when the coal is 1 based on the weight), even if there is such a concern, the countermeasures can be small and the equipment cost. Can be suppressed from increasing.

If only a small amount of wood pellets fall directly on the coal, it is not necessary to store or store a large amount of wood pellets directly on the coal. In addition, since the crushing of the wood pellets is performed at the same time as the crushing of the coal after being mixed with the coal, the transport route for transporting the wood pellets (especially the wood pellets discharged from the storage device is directly on the coal). It is not necessary to provide a temporary storage means for temporarily storing the wood pellets on the transport route for transporting to the landing position, and even if it is provided, it does not need to be a large temporary storage means. Therefore, (a) if the amount of wood pellets is 0.05 or less when coal is 1 based on the energy density, as in the thirteenth embodiment of the present invention, or (b). As in the fourteenth aspect of the invention, if the wood pellet is a black pellet having a coal content of 1 based on the energy density and is 0.3 or less, the temporary storage means becomes unnecessary or small. The equipment cost can be reduced by the amount that can be done with the thing.

In addition, when (a) wood pellets are 0.05 or less or (b) wood pellets are black pellets when coal is set to 1 based on the energy density, the black pellets should be 0.3 or less. For example, it can be said that the co-firing rate of coal and woody biomass fuel is relatively high, and the increase in the amount of carbon dioxide generated by combustion can be suppressed relatively well.

According to the embodiment M1 of the present invention, either one of the first co-firing fuel and the second co-firing fuel can be selectively produced. In addition, the crushing of the second fossil fuel and the second fossil fuel alternative fuel for producing the second co-firing fuel, and the fossil fuel (first fossil fuel) that composes the first co-firing fuel The same equipment (second crushing equipment) can be used for the crushing of the second fossil fuel to be prepared, and the transportation system can be simplified and the equipment cost can be avoided. be able to.

According to the embodiments M2, M3, M4, M5, M6, M7, M8 and M9 of the present invention, the ninth, first, sixth, seventh, second, twelfth, thirteenth and tenth, respectively. The effects produced by the four forms can be obtained.

As a whole, according to the present invention, the transport system for transporting a plurality of types of fossil fuel alternative fuels having different energy densities can be configured to be simpler as a whole and to avoid an increase in equipment cost. In order to obtain the effects produced by each form of the present invention (excluding fossil fuels and fossil fuel alternative fuels specified), a more suitable fossil fuel is coal, and fossil fuel alternative fuels are biomass fuel and wood. It is more suitable in the order of biomass fuel and wood pellets.

[First Embodiment]
<Basic form>
(1) FIG. 1 is a block diagram of a basic form of the first embodiment.

The transfer route for transporting the transported object, the devices that compose it, the transit section (hereinafter referred to as the "first transit section") J1 located at the position Na, and the transit section (hereinafter "second") located at the position Nb. It is equipped with a J2 (referred to as a "transfer section") and an operation control device 9.

The first transport path L1 is from the first storage device 1 to the fuel combustion device 7 capable of transporting the first fossil fuel alternative fuel discharged from the first storage device 1 to the fuel combustion device 7. It is a route to reach. The second transport path L2 is from the second storage device 2 to the fuel combustion device capable of transporting the second fossil fuel alternative fuel discharged from the second storage device 2 to the fuel combustion device 7. It is a route to reach. That is, the first transport path L1 and the second transport path L2 use a plurality of types of fossil fuel alternative fuels (first fossil fuel alternative fuel and second fossil fuel alternative fuel) as fuel by the devices constituting each of them. This is a route for charging into the combustion device 7.

The first storage device 1 and the second storage device 2 are provided with a first emission control means and a second emission control means (neither of which is shown), respectively, and the first storage device 1 and the second storage device 2 are provided. The emissions of the first fossil fuel alternative fuel from the device 1 and the emissions of the second fossil fuel alternative fuel from the second storage device 2 are the first emission control means and the second emission, respectively. It is adjusted by the control means.

The first transit unit J1 is a mechanism for transferring the transported object transported by the device constituting the first transport path L1 to the device constituting the transport path between the position Na and the position Nb. , It is provided with a mechanism for transferring the object to be transported by the device constituting the second transport path L2 to the device constituting the transport path between the position Na and the position Nb. A typical example of each mechanism is a hopper or a chute device installed between a transport device on the upstream side and a transport device on the downstream side to guide an object to be transported to the transport device on the downstream side.

The above two mechanisms included in the first transit unit J1 may be known and may be (a) a single device or (b) separate devices. In the former example (a), the discharge destination common to the transported object transported by the device constituting the first transport path L1 and the transported object transported by the device constituting the second transport path L2. An example of the latter (b) is a plurality of hoppers and chute devices prepared as discharge destinations of the respective objects to be transported (see FIG. 1 of JP-A-62-89221).

The second transit portion J2 transfers the transported object transported by the device constituting the transport path between the position Na and the position Nb to either the first transport path L1 or the second transport path L2. It is equipped with a mechanism for transferring to the devices that make up the. The mechanism may be known, and a typical example thereof is one of a plurality of transport devices on the downstream side, which is installed between a transport device on the upstream side and a plurality of transport devices on the downstream side. It is a transfer device that guides the user to (see Japanese Patent Application Laid-Open No. 60-16421, Japanese Patent Application Laid-Open No. 8-151116, Japanese Patent Application Laid-Open No. 8-143135).

The second transfer unit J2 transfers the transported object transported from the upstream side only to the device constituting either the first transport path L1 or the second transport path L2. Therefore, in the transport system W, the transported object may not be transferred to the device constituting either the first transport path L1 or the second transport path L2 by the second transfer unit J2.

(2) The operations (including cooperation between the devices) of the devices (including the first transfer section J1 and the second transfer section J2) that make up the transfer system W are in operation, except for those that require manual operation. It is controlled by the control device 9. For example, (a) the operation of the emission control means provided in each of the first storage device 1 and the second storage device 2, and (b) the change of the discharge source of the transported object (first storage device 1 and). The change from one of the second storage devices 2 to the other) is controlled by the operation control device 9.

When the emission control means provided in each of the first storage device 1 and the second storage device 2 includes device elements such as a discharge valve, a feeder, a bridge prevention means, and a measuring device, it is controlled by the operation control device 9. The operation of the emission control means includes at least one operation of the device element. Further, in the control by the operation control device 9 of the operation of the discharge amount control means, the opening degree of the discharge valve (including opening / closing), the moving speed of the object to be conveyed by the feeder (or the amount of transportation per unit time), and bridge prevention are performed. Degree of operation of the means (including operation / non-operation), operation / non-operation of the measuring device, timing of signal collection / reception by the measuring device, discharge unit outlet of the first storage device 1 or the second storage device 2. Includes controls such as the payout rate (or payout amount per unit time) of the containment delivered from.

That is, the respective routes of the first transport route L1 and the second transport route L2 on the downstream side of the second transit portion J2 are fixed, and the operation control device 9 so that the route is not changed from one to the other. Is controlled by. More specifically, in the second transit section J2, whether the transported object to be transported from the upstream side is the first fossil fuel alternative fuel or the second fossil fuel alternative fuel. Regardless of, when the transported object is discharged from the first storage device 1, the transported object is discharged toward the device constituting the fixed transport path as the first transport path L1. Then, when the fuel is discharged from the second storage device 2, the operation control device 9 is discharged so that the transported object is discharged toward the device constituting the fixed transport path as the second transport path L2. Is controlled by.

(3) The first transport route L1 and the second transport route L2 are routes capable of transporting the first fossil fuel alternative fuel and the second fossil fuel alternative fuel having different energy densities. In the range up to the fuel combustion device 7, more specifically, the same path is in the range of the path between the position Na and the position Nb, and the same device (located in each of the position Na and the position Nb) in that range. It is composed of the first transit section J1 and the second transit section J2).

That is, this transfer system W has a shared path in the range where the first transfer path L1 and the second transfer path L2 reach the fuel combustion device 7, and the first transfer path L1 is configured in that range. Since a part of the equipment to be used and a part of the equipment constituting the first transport path L1 form a shared device, the configuration is simpler and can avoid an increase in equipment cost.

It has the route L12. The second supply line includes a supply path L21 for replenishing the second fossil fuel alternative fuel to the first storage device 1 and a transport path L22 for replenishing the second storage device 2.

The first fossil fuel alternative fuel is discharged from the first fossil fuel alternative fuel receiving / supplying facility 11, and by the equipment constituting the first supply lines L11 and L12, the first storage device 1 and the second It is selectively supplied to either one or both of the storage devices 2. The second fossil fuel alternative fuel is discharged from the second fossil fuel alternative fuel receiving / supplying facility 12, and by the equipment constituting the second supply lines L21 and L22, the first storage device 1 and the second It is selectively supplied to either one or both of the storage devices 2.

(2) The operations (including cooperation between the devices) of the devices that make up the raw material receiving / supplying facility V0 and the other devices that make up the transport system W are not shown, except for those that require manual operation. It is controlled by the control device 9. For example, the selective supply of the first fossil fuel alternative fuel and the second fossil fuel alternative fuel to either or both of the first storage device 1 and the second storage device 2, respectively, is the operation control device 9. Is controlled by.

By selectively supplying either one or both, fossil fuel alternative fuel that needs to be transported to the fuel combustion device 7 is replenished to each of the first storage device and the second storage device, and the fuel is burned. The transfer to the device 7 is performed without interruption or delay.

<Modification 2>
(1) FIG. 3 is a block diagram of a modification 2 of the first embodiment. The fossil fuel alternative fuel transfer system W shown in FIG. 3 is the same as that shown in FIG. 2 (modification example 1) except for at least the following (a) to (c): (a) first transfer. The first processing device 4 is provided between the position Nb in the path L1 and the fuel combustion device 7, and (b) the second processing device 4 is provided between the position Nb in the second transfer path L2 and the fuel combustion device 7. The processing device 5 is provided, and (c) the first transfer path L1 and the first transfer path L2 are the devices constituting each of them (including the first processing device 4 and the second processing device 5). It is a route to input a plurality of types of fossil fuel alternative fuels (first fossil fuel alternative fuel and second fossil fuel alternative fuel) that have been crushed and / or mixed by the fuel to the fuel combustion apparatus 7. ..

The second transit section J2 transfers the transported object transported from the upstream side only to the device constituting either the first transport path L1 or the second transport path L2. Therefore, in this transport system W, the transported object may not be charged into either the first processing device 4 or the second processing device 5.

(2) The operations (including cooperation between the devices) of the first processing device 4, the second processing device 5, and the other devices constituting the transfer system W are shown in the figure except for those requiring manual operation. It is controlled by the operation control device 9 that is not used.

(3) The first transport path L1 has a shared path with a part of the second transport path L2 in the range of the path from the first storage device 1 to the first processing device 4, and the second The transport path L2 has a shared path with a part of the first transport path L1 in the range of the path from the second storage device 2 to the second processing device 5, and in those ranges, the first A part of the devices constituting the transport path L1 and a part of the devices constituting the first transport path L1 form a shared device with each other. Therefore, this transport system W has a simpler configuration that can avoid an increase in equipment cost.

<Modification 3>
(1) FIG. 4 is a block diagram of a modification 3 of the first embodiment. The fossil fuel alternative fuel transfer system W shown in FIG. 4 is the same as that shown in FIG. 3 (modification example 2) except for at least the following (a) to (e): (a) third storage. It has a third transport path L3 for transporting fossil fuel discharged from the device 3 to the fuel combustion device 7, and the devices that compose it, and (b) has a raw material receiving / supplying facility V, and a third. It is possible to replenish the fossil fuel to the storage device 3 of the above, and (c) the first transfer path L1 and the second transfer path L2 downstream from the inheritance J2 # located at the position Nb are each transported. It is not fixed as a route and can be changed from one to the other. (D) The second transport route L2 (or the first transport path L1 depending on the operation of the inheritance unit J2 #) and the first. All of the three transport paths L3 pass through or pass through the second processing device 5, and (e) multiple types of co-firing fuel (first co-firing fuel and second co-firing fuel). Can be manufactured and put into the fuel combustion device 7.

In addition to the configuration of the raw material receiving / supplying facility V0, the raw material receiving / supplying facility V stores fossil fuel discharged from the fossil fuel receiving / supplying facility 13 and the fossil fuel receiving / supplying facility 13 as a third storage device 3 It is equipped with a third supply line L33 that transports to and the equipment that composes it.

The third storage device 3 is provided with an emission control means (not shown), and the emission amount of fossil fuel from the third storage device 3 is adjusted by the emission control means.

The third transport path L3 does not have the same path as either the first transport path L1 or the second transport path L2 on the upstream side of the second processing apparatus 5, and the second transport path L2 ( Alternatively, depending on the control by the operation control device 9, it is connected to the second processing device 5 separately from the first transport path L1), and is on the downstream side of the second processing device 5, that is, the second processing device 5 and the fuel. It forms the same path as the second transfer path L2 (or the first transfer path L1) with the combustion device 7.

Similar to the second transit section J2, the transfer section J2 # transfers the transported object transported by the device constituting the transport path between the position Na and the position Nb to the first transport path L1 and the second transport path L1 and the second. It is equipped with a mechanism for transferring to the equipment that constitutes either one of the transport paths L2. A known mechanism is sufficient. Further, due to the function, in this transport system W, the transported object may not be charged into either the first processing device 4 or the second processing device 5.

The second transport path L2 (or the first transport path L1 depending on the operation of the successor J2 #) and the third transport path L3 form the same path on the upstream side of the second processing device 5 with each other. They are connected to the second processing device 5 at different points without any notice, but all of them pass through or pass through the second processing device 5. In that case, the fossil fuel and the fossil fuel substitute fuel can be charged into the second processing apparatus 5 at the same time or can be selectively charged. When the fossil fuel and the fossil fuel substitute fuel are selectively transported to the fuel combustion device 7 and input at the same time, the fuel for co-firing containing the fossil fuel and the fossil fuel substitute fuel as a composition is sent to the fuel combustion device 7. It will be transported toward.

(2) The operations (including cooperation between the devices) of the devices (including the first transit section J1 and the succession section J2 #) that make up this transfer system W are shown in the figure except for those that require manual operation. It is controlled by the operation control device 9 that is not used. For example, (a) the operation of the emission control means provided in the third storage device 3, (b) the operation of the inheritance unit J2 #, (c) the selective change of the transport route downstream from the inheritance unit J2 #, and (D) The method of inputting the fossil fuel and / or the fossil fuel alternative fuel into the second processing device 5 (including the selection of simultaneous input or alternative input) is determined by the operation control device 9 (not shown). It is controlled.

When the discharge amount control means provided in the third storage device 3 includes device elements such as a discharge valve, a feeder, a bridge prevention means, and a measuring device, the operation of the discharge amount control means controlled by the operation control device 9 is performed. Includes at least one operation of the device element. Further, the control of the operation of the emission control means by the operation control device 9 includes the control of the emission rate (or the emission amount per unit time) of the fossil fuel discharged from the third storage device 3.

In this transfer system W, unlike the case of the modified example 2, each of the first transfer path L1 and the second transfer path L2 is a changeable route, and more specifically, from the inheritance unit J2 #. The transport route may be selectively changed on the downstream side. The selective change is controlled by the operation control device 9 depending on whether the transported object transported from the upstream is the first fossil fuel alternative fuel or the second fossil fuel alternative fuel. For example, if the first fossil fuel alternative fuel is set to be crushed and / or mixed by the first processing device 4 and the second fossil fuel alternative fuel is set to be processed by the second processing device 5. Or, when the first transfer path L1 and the second transfer path L2 are set to pass through or pass through the first processing device 4 and the second processing device 5, respectively, (a) the first storage device. If the transported object discharged from 1 is the second fossil fuel alternative fuel and the transport route on the downstream side of the inheritance section J2 # is the first transport route, change this to the second transport route. , (B) When the transported object discharged from the second storage device 2 is the first fossil fuel alternative fuel and the transport route downstream from the inheritance section J2 # is the second transport route, this is the case. Is changed to the first transport route.

When the transported object transported from the upstream side is the first fossil fuel alternative fuel, the inherited portion J2 # is the first transport path L1 (second) that passes through or passes through the first processing device 4. Discharge the object to be transported toward the equipment constituting the first transport route L1 changed from the transport route L2, and if it is a second fossil fuel alternative fuel, go through the second processing device 5. Or, the operation control device 9 so as to discharge the transported object toward the device constituting the first transport path L2 passing through (including the second transport path L2 changed from the first transport path L1). Is controlled by.

(3) The second transport path L2 (or the first transport path L1 depending on the control by the operation control device 9) and the third transport path L3 both pass through or pass through the second processing device 5. Therefore, the second processing device 5 is shared, and moreover, the second transport is carried out in the range downstream of the second processing device 5, that is, between the second processing device 5 and the fuel combustion device 7. A part of the route L2 (or the first transportation route L1) and a part of the third transportation route L3 form a shared route, and the equipment constituting the shared route (excluding the second processing equipment 5) is shared. is doing. Therefore, this transport system W has a simpler configuration that can avoid an increase in equipment cost.

(4) This transfer system W inputs the fossil fuel substitute fuel processed by the first processing device 4, the fossil fuel processed by the second processing device 5, and / or the fossil fuel substitute fuel into the fuel combustion device 7. Not only is it possible to do this, but by simultaneously charging the fossil fuel and the fossil fuel substitute fuel into the second processing device 5 and processing them there, a co-firing composed of the fossil fuel and the fossil fuel substitute fuel is produced. It makes it possible to manufacture fuel for fuel and put it into the fuel combustion device 7. In addition, this transport system W processes fossil fuels selected from a plurality of types of fossil fuel alternative fuels (first fossil fuel alternative fuel and fossil fuel alternative fuel) having different energy densities by the second processing apparatus 5. By doing so, it is possible to separately produce co-firing fuels (first co-firing fuel and second co-firing fuel) having different energy densities and input them into the fuel combustion apparatus 7.

<Modification example 4>
(1) FIG. 5 is a block diagram of a modification 4 of the first embodiment. The fossil fuel alternative fuel transfer system W shown in FIG. 5 is the same as that shown in FIG. 4 (modification example 3) except for the following (a) and (b): (a) Second processing apparatus. It has a transit section (hereinafter referred to as the "third transit section") J3 located at the position Nc on the upstream side of 5, and (b) between the position Nc and the second processing device 5. The second transport path L2 (or the first transport path L1 depending on the control by the operation control device 9 (not shown)) and the third transport path L3 form the same route, and therefore the second transport path L2. (Or the first transfer path L1) and the third transfer path L3 are connected to the second processing device 5 at one place.

The third transit unit J3 is a device that constitutes the second transfer path L2 (or the first transfer path L1) for the object to be conveyed that has been conveyed by the device that constitutes the third transfer path L3 at the position Nc. , Or a mechanism for transferring the object to be conveyed by the device constituting the second transport path L2 (or the first transport path L1) to the device constituting the third transport path L3. ing. A typical example of the mechanism is a hopper or a chute device installed between a transport device on the upstream side and a transport device on the downstream side to guide an object to be transported to the transport device on the downstream side. A device that transfers one transported object from one transported device to the other transported device by dropping it onto the other transported object is also a typical example of the mechanism. Since the basic function of the mechanism is the same as the basic function of either of the two mechanisms (described above) provided in the first transit unit J1, the description thereof will be omitted.

Since the inheritance unit J2 # transfers the object to be conveyed from the upstream side only to the device constituting either the first transfer path L1 or the second transfer path L2, the inheritance unit J2 # The fossil fuel alternative fuel may not be transported to the third transit section J3 located on the downstream side, and therefore may not be input to the second processing device 5. In that case, the second processing apparatus 5 grinds and / or mixes only the fossil fuel.

The second transport path L2 (or the first transport path L1) and the third transport path L3 pass through or pass through the second processing device 5, and the fossil fuel and the fossil fuel alternative fuel are processed in the second process. It can be charged into the device 5 at the same time or can be charged alternately. Therefore, as in the case of the one shown in FIG. 4 (modification example 3), when the fuel is selectively charged, the fossil fuel and the fossil fuel substitute fuel that have been crushed / mixed in advance are selectively added to the fuel combustion device 7. When the fuel is transported toward the fuel and is charged at the same time, the fuel for co-firing containing the fossil fuel and the fossil fuel substitute fuel as a composition is transported toward the fuel combustion device 7.

When fossil fuel and fossil fuel alternative fuel are selectively charged into the second processing device 5, they have been transported by the third transit section J3 and (a) by the device constituting the third transport path L3. Transfer the fossil fuel to a device that constitutes the second transport path L2 (or the first transport path L1) and does not transport the object to be transported, or (b) the second transport path. The second fossil fuel alternative fuel (or the first fossil fuel alternative fuel) transported by the device constituting L2 (or the first transport path L1) is the device constituting the third transport path L3. The object to be transported will be transferred to the one that has not been transported. On the other hand, when the fossil fuel and the fossil fuel substitute fuel are simultaneously charged into the second processing device 5, they have been transported by the third transit section J3 and (a) by the device constituting the third transport path L3. Transfer the fossil fuel to the equipment that constitutes the second transport path L2 (or the first transport path L1), or (b) configure the second transport path L2 (or the first transport path L1). The fossil fuel alternative fuel (second fossil fuel alternative fuel or second fossil fuel alternative fuel) transported by the device will be transferred to the device constituting the third transport path L3. In any case, unless a separate mixing device is provided, the fossil fuel and the fossil fuel alternative fuel coexist without mixing (for example, one of the substances) until they are put into the second processing device 5. The other substance is deposited on top or thinly dispersed) and transported.

(2) The operation (including cooperation between the devices) of the devices (including the third transit unit J3) that make up this transfer system W is an operation control device (not shown) except for those that require manual operation. It is controlled by 9.

(3) In the range between the position Nc and the second processing apparatus 5, a part of the second transport path L2 (or the first transport path L1) and a part of the third transport path L3 are shared paths. And shares the devices that make up the shared route. Therefore, this transport system W is not inferior to the modified example 3, and has a simpler configuration that can avoid an increase in equipment cost.

<Modification 5>
(1) FIG. 6 is a block diagram of a modification 5 of the first embodiment. In the fossil fuel alternative fuel transfer system W shown in FIG. 6, the position Nc is transported by a device constituting the second transfer path L2 (or the first transfer path L1 depending on the control by the operation control device 9). The position where the fossil fuel alternative fuel (first fossil fuel alternative fuel or second fossil fuel alternative fuel) directly falls on the fossil fuel transported by the device constituting the third transport path L3 (the position where it falls directly on the fossil fuel. It is the landing position Qf), in other words, the third transit section J3 is limited to the mechanism by which the fossil fuel alternative fuel directly falls on the fossil fuel (near the position Nc in FIG. 5). The configuration is the same as that shown in FIG. 5 (modification example 4) except that the configuration is changed from [Z1] to [Z2]).

(2) In this transport system W, the fossil fuel and the fossil fuel alternative fuel directly falling on the fossil fuel are coal and wood pellets, respectively, and when coal is 1 based on the weight, the wood pellet is Since the amount is as small as 0.069 or less, no temporary storage means (bunker) is provided in the landing position Qf or the second transport path L2 (or the first transport path L1) on the upstream side thereof. Adhesion to the surrounding wall surface is also difficult to manifest as a problem, and there is not much dust generated, so we have not taken any significant measures against deposits or dust, but even if some measures are taken, a small one will suffice.

Since the weight of the fossil fuel on which the fossil fuel alternative fuel is falling is at most 1.069 times the weight of the fossil fuel before the fossil fuel is falling, the transportation for transporting the fossil fuel on which the fossil fuel alternative fuel is not falling is carried. The device is used as it is as a device constituting a third transport path for transporting fossil fuel on which a small amount of fossil fuel substitute fuel is falling. Also, when crushing and / or mixing the load generated in the processing equipment when crushing and / or mixing the fossil fuel on which the fossil fuel substitute fuel is not applied, and when crushing and / or mixing the fossil fuel on which a small amount of the fossil fuel alternative fuel is applied. For crushing and / or mixing fossil fuels to which no fossil fuel alternative fuel has fallen, as there is no significant difference (to the extent that larger or higher performance of the processing equipment is required) with that that occurs in the processing equipment. The processing device is used as it is as the second processing device 5 (or the first processing device 4) for crushing and / or mixing the fossil fuel on which a small amount of fossil fuel substitute fuel is falling.

In particular, when the fossil fuel is coal and the fossil fuel alternative fuel is black pellets among woody biomass fuels, the amount of black pellets is 0 when coal is set to 1 based on the calorific value per unit weight. Adjust to .3 or less. This amount of black pellets is preferable because the co-firing rate of black pellets is relatively high. In addition, the amount of this black pellet may be sufficient for (a) small-scale upsizing or high-performance of the transporting device for transporting coal and the crushing device for crushing coal, or ( b) If there is a margin in the performance of the original device (more specifically, if it is a transport device with originally high transport performance or if it is a crusher with originally high crushing performance), it can be used as it is. It is a small amount and is preferable.

In addition, when there is no margin of performance in the transport device for transporting fossil fuel and the processing device for crushing and / or mixing, or when the initial surplus capacity has decreased due to deterioration. As it is, it cannot be used as a device for transporting fossil fuels on which fossil fuel substitute fuels are falling or as a device for crushing and / or mixing, so that the performance of the device can be enhanced or larger or higher. It will be necessary to introduce performance transfer equipment and processing equipment. However, since the amount of fossil fuel alternative fuel that is falling is small, the performance enhancement or large-scale or high-performance can be small-scale, and the increase in equipment cost can be suppressed.

(3) The operation (including cooperation between the devices) of the devices (including the third transit unit J3) constituting this transfer system W is an operation control device (not shown) except for those requiring manual operation. It is controlled by 9. For example, the amount of fossil fuel substitute fuel that falls directly on the transported fossil fuel is set to the amount so that the calorific value ratio or weight ratio of the fossil fuel and the fossil fuel substitute fuel is within a predetermined value or range. It is controlled by the operation control device 9 along with the operation of the affected device. The predetermined value or value range is an internal element such as the shape, properties, and physical properties of the fossil fuel or the fossil fuel substitute fuel (when the fossil fuel and the fossil fuel substitute fuel can be mixed or co-firing), the fossil fuel substitute fuel (Including mixing rate or co-firing rate), the discharge rate of the contained material from the outlet provided in the discharge section of the storage device (or the amount to be discharged per unit time), and the transport route for the contained material discharged from the storage device. It is determined in advance by comprehensively considering external factors such as the transport speed (or the transport amount per unit time) of the transport device to be transported and the combustion conditions of the fuel combustion device.

(4) When the fossil fuel alternative fuel (first fossil fuel alternative fuel or second fossil fuel alternative fuel) is dropped on the transported fossil fuel, the distribution of the fossil fuel alternative fuel to the fossil fuel is distributed. I try to make it uniform. If the distribution is uniform, it will be easier to carry out subsequent crushing and / or mixing stably, and the quality of the resulting co-firing fuel composed of fossil fuel and fossil fuel alternative fuel will also be stable and easy to maintain. Is.

Since the fact that the fossil fuel substitute fuel is dropped on the fossil fuel itself is a method that facilitates the adjustment to make the distribution of the fossil fuel substitute fuel uniform with respect to the fossil fuel, this transport system employs a remarkable adjustment means. However, if necessary, a known adjusting means may be adopted to positively make the distribution uniform. For example, when the transport device is a belt conveyor device, the distribution can be made uniform by relatively changing the landing position Qf (Japanese Patent Laid-Open Nos. 6-227640 and 8-151116). See Japanese Patent Application Laid-Open No. 2000-313518).

<Modification 6>
(1) FIG. 7 is a block diagram of a modification 6 of the first embodiment. The fossil fuel alternative fuel transfer system W shown in FIG. 7 is the same as that shown in FIG. 6 (modification example 5) except for the following (a) and / or (b): (a) first. The storage device 1 is provided with a plurality of storage devices Sa and Sb arranged in parallel with respect to the first transfer path L1 and / or (b) the second storage device 2 is provided with respect to the first transfer path L2. Must be equipped with multiple storage devices Sc and Sd arranged in parallel.

Although both (a) and (b) are depicted in FIG. 7, it is sufficient for the transport system W shown in FIG. 7 to have at least one of the above configurations (a) and (b). The vicinity of the position Nc in FIG. 7 has the configuration of [Z2] in FIG. 6, but it may have the configuration of [Z1] in FIG.

(2) In FIG. 7, only one of the first fossil fuel alternative fuel and the second fossil fuel alternative fuel is supplied from the raw material receiving / supplying facility V to the storage devices Sa and Sb. Only others are supplied to the storage devices Sc and Sd. That is, when the first fossil fuel substitute fuel is supplied to the storage devices Sa and Sb through the path L11 of the first supply line, the second fossil fuel substitute is made through the path L22 of the second supply line. When the fuel is supplied to the storage devices Sc and Sd and the second fossil fuel alternative fuel is supplied to the storage devices Sa and Sb through the route L21 of the second supply line, the first supply line The first fossil fuel alternative fuel is supplied to the storage devices Sc and Sd through route L12.

Each of the storage devices Sa, Sb, Sc, and Sd is provided with at least a discharge unit 20 (20a, 20b, 20c, 20d) and a discharge amount control means, and the discharge amount control means is a discharge valve 21 (21a, 21b). , 21c, 21d), feeder 22 (22a, 22b, 22c, 22d), bridge prevention means 23 (23a, 23b, 23c, 23d) and a measuring device (not shown).

Substances discharged from the discharge unit outlet of the storage device Sa are transported by the feeder 22a, and substances discharged from the discharge unit outlet of the storage device Sb are transported by the feeder 22b to the hopper H1 equipped with emission control means and stored. Will be done. The hopper H1 discharges the substance from the discharge portion of the hopper H1 toward the transport device constituting the first transport path L1 at the position Q1 while maintaining a certain amount of the substance as an object to be contained.

Substances discharged from the discharge unit outlet of the storage device Sc are transported by the feeder 22c, and substances discharged from the discharge unit outlet of the storage device Sd are transported by the feeder 22d to the hopper H2 equipped with emission control means and stored. Will be done. The hopper H2 discharges the substance to be contained from the discharge portion of the hopper H2 toward the transport device constituting the second transport path L2 at the position Q2 while maintaining a certain amount of the substance to be contained. do.

(3) Since the amount of the substance discharged from the hopper H1 toward the transport device constituting the first transport path L1 needs to be maintained within a predetermined value or value range by the discharge amount control means, the storage device. When the amount of the contained material contained in either the Sa or the storage device Sb decreases, the amount of the contained material contained in the hopper H1 is suppressed from being excessively changed. It is necessary to switch the emission source of the contained material from one of them to the other. The same applies to the storage device Sc and the storage device Sd, and when the amount of the contained material contained in one of the storage units decreases, the amount of the contained material contained in the hopper H2 is excessive. It is necessary to switch the emission source of the contained material from one to the other while suppressing fluctuations.

FIG. 8 shows that the discharge of the contained material from one storage device (hereinafter referred to as “storage device S1”), which can be adopted in the transfer system shown in FIG. 7, is referred to as the other storage device (hereinafter referred to as “storage device S2”). It is a schematic explanatory diagram of an example of control for switching to discharge from (referred to as). The storage device S1 and the storage device S2 represent one or the other of the storage device Sa and the storage device Sb, respectively, and represent one or the other of the storage device Sc and the storage device Sd, respectively.

(A) In FIG. 8, the horizontal axis is time, and the vertical axis is the amount of the substance discharged into the hopper from each of the storage device S1 and the storage device S2 or the amount of the substance charged into the hopper by the discharge thereof. In FIG. 8 (a), k1 and k2 show changes over time in the amount of the contained substance discharged from the storage device S1 and the storage device S2, respectively, and in FIG. 8 (b), kt is k1. It shows the total amount of k2.

(B) The initial emission (equivalent to 100) of the contained material from the storage device S1 starts to decrease from time T0, then decreases until time T4, and the emission after time T4 reaches zero. The storage device S1 is replenished with substances from the raw material receiving / supplying facility V at an appropriate timing after the time T4, and is made ready to discharge 100 equivalents again.

When the measuring device detects that the amount of discharge from the storage device S1, which was initially equivalent to 100, has dropped to the predetermined value Y1 at time T1, the operation control device 9 is provided in the storage device S2 based on the detection result. A signal is sent to the emission control means instructing the emission of the contained matter. The amount of the contained material discharged from the storage device S2 is from time T2 after an unavoidable delay in response (elapse of time from time T1 to time T2) from the discharge control means receiving the signal. It increases, and then increases until time T4, compensating for the decrease in the amount of contained material discharged from the storage device S1, and the amount discharged after time T4 reaches the equivalent of 100.

The amount of the contained material discharged from the storage device S1 is detected as Y1 by the measuring device, and then decreases to Y2 with the passage of time from the time T1 to the time T2. Alternatively, by modifying the computer program executed in the operation control device 9, the locus of k2 is adjusted so that the decrease is compensated by the amount of the contained material discharged from the storage device S2. Specifically, due to the operation of the emission control means based on the signal from the operation control device 9, the emission amount per unit time (gradient of k2) of the contained material from the storage device S2 is from time T2 to time T3. The time between is adjusted to be larger than that from time T3 to time T4.

Since the hopper during normal operation continues to hold a certain amount of contained matter as a result of the equilibrium between input and discharge of substances, if the fixed amount kt is the sum of k1 and k2, kt is shown in Fig. 8 ( As shown in b), it fluctuates over time, and the fluctuation ranges from Y2 to Y4. At this time, the fluctuation range of kt (the fluctuation range from Y2 to Y4) is controlled by the operation control device 9 so that it is within the allowable fluctuation range. For example, in the case shown in FIG. 8A, for k1, the time T4 is controlled to be later by the operation of the emission control means (particularly the bridge prevention means) provided in the storage device S1, and k2. With respect to, the value of the threshold value Y1 and the value of time T3 (gradient between time T2 and time T3) are controlled so that the decrease of k1 can be compensated by the increase of k2.

Thus, the switching of the emission source from the storage device S1 to the storage device S2 is completed.

(C) After that, according to the content of replacing "storage device S1" and "storage device S2" in the above explanation with "storage device S2" and "storage device S1", respectively, the cover from the storage device S2. The decrease in the amount of the contained material is compensated for by the discharge from the storage device S1 while the fluctuation range of the amount of the contained material contained in the hopper is suppressed as much as possible, thereby moving from the storage device S2 to the storage device S1. Emissions are switched. Then, after that, the switching of the discharge of the contained material is repeatedly performed between the storage device S1 and the storage device S2.

<Modification 7>
(1) FIG. 9 is a block diagram of a modification 7 of the first embodiment. The fossil fuel alternative fuel transfer system W shown in FIG. 9 is the same as that shown in FIG. 7 (modification example 6) except for the following (a) and / or (b): (a) Storage device Sa. , The hopper H1 is not interposed between the feeders 22a and 22b provided in Sb and the transfer device constituting the first transfer path L1, and therefore, the discharge units 20a and 20b of the storage devices Sa and Sb are provided. The fossil fuel alternative fuel discharged from the feeders 22a and 22b from the outlet constitutes the first transport path L1 from the feeders 22a and 22b without being accommodated in the hopper H1 after being transported by the feeders 22a and 22b. The hopper H2 is interposed between the feeders 22c and 22d provided in the storage devices Sc and Sd and the transfer device constituting the second transfer path L2 to be transferred to the transfer device and / or (b). Therefore, the fossil fuel alternative fuel discharged to the feeders 22c and 22d from the outlets provided in the discharge units 20c and 20d of the storage devices Sc and Sd is transported by the feeders 22c and 22d and then stored in the hopper H2. It is transferred from the feeders 22c and 22d to the transfer device constituting the second transfer path L2 without any trouble.

In FIG. 9, both the above (a) and (b) are depicted, but in the transfer system W shown in FIG. 9, it is sufficient to have at least one of the above configurations (a) and (b). Although the vicinity of the position Nc in FIG. 9 has the configuration of [Z2] in FIG. 6, it may have the configuration of [Z1] in FIG.

It is a schematic explanatory diagram of an example of control for switching to discharge from (hereinafter referred to as "storage device S2 *"). This control is executed by the operation control device 9. The storage device S1 * and the storage device S2 * and the position Q1 and the position Q2 represent one and the other of the storage device Sa and the storage device Sb, as well as the position Qa and the position Qb, respectively, and the storage device Sc and the storage device Sc and the storage device Sb. Represents one and the other as well as position Qc and position Qd of the device Sd.

Each of the storage devices S1 * and the storage device S2 * has a plurality of storage units separated from each other along the height direction of the storage device in order to easily grasp the decrease in the residual level of the contained material and its tendency. A plurality of contact-type level measuring devices for measuring the residual level at the position of, and one or more non-contact level measuring devices for measuring the position of the contained object from above the accommodating portion are installed. There is. The former contact-type level measuring device includes one suspended from the upper part of the accommodating portion and one attached to the side surface of the accommodating portion. The latter non-contact level measuring device includes a device that involves processing image information obtained by photographing an object to be contained from above the accommodating portion.

When an accurate value is obtained from the measured value by the level measuring device, the measured value is further calibrated by the operation control device 9 based on the measured value by another one or a plurality of level measuring devices. The residual level between the measurement position of the level measuring device and the measuring position of another level measuring device is calculated by the operation control device 9 based on the signals from the plurality of and / or the plurality of types of level measuring devices.

It should be noted that (a) the time from a reference time such as the time when the contained material reaches a certain residual level to the time when the amount of the contained material discharged from the discharge unit outlet of the storage device starts to decrease. (B) The time from the reference time to the time when the decrease in the amount of the contained item ends (for example, the time when the amount of the item is reduced to zero or a predetermined value), (c) the item to be contained. Changes over time in the decrease in the amount of inmates paid out from the time when the amount of withdrawal starts to decrease to the time when the decrease ends, (d) of the bridge prevention measures for each of (a) to (c) on the left Effect of operation and / or implementation of measures to delay payout reduction, which will be described later (including the effect of presence / absence), and (e) Judgment of various conditions arranged in consideration of the data related to (a) to (d) on the left. Is known in advance through the collection and analysis of actual measurement data for each of the storage device S1 * and the storage device S2 *, simulation by a mathematical model, etc., and is unique to each of the storage device S1 * and the storage device S2 *. It is recorded in the storage unit of the operation control device 9 in a format that can be referred to by the calculation unit.

The distance between the position Q1 located on the upstream side and the position Q2 located on the downstream side along the transport direction of the transported object, and therefore the time required for the transported object to reach the position Q1 from the position Q2, is At least, it is set within a range that does not interfere with the control for switching the discharge between the storage device S1 * and the storage device S2 * described below.

(2-1) FIGS. 10 and 11 show that the decrease in the amount of discharge from the storage device S1 * on the upstream side is compensated for by the discharge from the storage device S2 * on the downstream side, whereby the storage device S1 * to the storage device S2 It is a schematic explanatory diagram of an example of control for switching discharge to *. In each figure, (A) and (B) explain the control process in which the storage device S1 * and the storage device S2 * are related, respectively.

(2-1-1) First, in the storage device S1 * on the upstream side, the feeder and other emission control means are in operation, and the emission valve of the discharge section is opened by the other emission control means. The contents to be contained in the accommodation unit are discharged from the outlet of the discharge unit toward the feeder, transported to the position Q1 by the feeder, and transported to the fuel combustion device 7 at the position Q1. It is transferred to the transfer device that constitutes the route, and is transported to the final destination (fuel combustion device 7) on the downstream side via the position Q2 by the transfer device (process s101). The amount of the object to be conveyed by the transfer device is assumed to be 100.

As the content to be contained is discharged from the outlet of the discharge unit, the residual level of the content to be contained in the storage unit decreases, and when the preset residual level 1 is reached, the level measuring device becomes the residual level 1 at that time. The corresponding signal 1 is transmitted (step s102). When the amount of objects to be contained in the storage device S1 * is further reduced and reaches the preset residual level 2, the level measuring device transmits the signal 2 corresponding to the residual level 2 (step s103). ). The transmission destination of the signal 1 and the signal 2 is the operation control device 9.

After the contained material in the accommodating portion reaches the residual level 2, the operation of the bridge preventing means is started (step s104). The timing of starting the operation of the bridge prevention means and the method of operating the bridge prevention means are not particularly limited as long as the control purpose of switching the discharge source of the contained object can be achieved. The operation may be started before the remaining level 2 is reached, and may be continuous operation, temporary operation, or intermittent operation.

The contents to be discharged from the discharge unit outlet to the feeder start to decrease, and continue to decrease (step s105), and are transported to the position Q1 by the feeder as in the case of step s101 before the start of the decrease. Then, it is transferred to the transfer device constituting the transfer path, and further transferred to the position Q2 by the transfer device and toward the downstream side from the position Q2 (step s106). Therefore, the contained object is transported in the order of the portion where the reduction of the payout is started (hereinafter referred to as “decrease starting portion”) and the subsequent reduced portion, and reaches the position Q2 as the transported object (step s107, Process s108). For the first time at location Q2, the contained material is combined with the contained material discharged from the storage device S2 * and is transported together by the same transport device toward the downstream side of position Q2.

(2-1-2) On the other hand, in the storage device S2 * on the downstream side, the discharge section outlet is initially fully closed, and the containment section is in a state where the contained material is replenished by the raw material receiving / supplying facility V, and the feeder. Is not operating (process S201), but based on the command signal transmitted from the operation control device 9 that received the signal 1, the storage device S2 * is ready for operation, and after the preparation is completed, it waits for the next command signal. The state is reached and the operation of the feeder is started (process s202).

Next, in the storage device S2 *, based on the command signal transmitted from the operation control device 9 that has received the signal 2, the discharge valve of the discharge unit is released after a predetermined delay time Pt [s2 *] following the reception of the command signal has elapsed. It will be opened, and the discharge of the contained material from the outlet of the discharge unit to the feeder will be started, and the discharge amount will increase (step s203). The opening degree of the discharge valve in the open state and the degree of increase in the amount of the contained material to be discharged (including the change over time) are adjusted by the discharge amount control means under the control of the operation control device 9. To.

The contained material discharged to the feeder is transported to the position Q2 by the feeder (step s204). Therefore, the contained object is transported in the order of the portion where the increase in the payout is started (hereinafter referred to as “increased start portion”) and the subsequent increased portion, and reaches the position Q2 as the transported object (step s205, Step s206). For the first time at location Q2, the contained material is combined with the contained material discharged from the storage device S1 * and is transported together by the same transport device toward the downstream side of position Q2.

(2-1-3) The total amount of the contained items discharged from the storage device S1 * and the contained items discharged from the storage device S2 *, which are combined at the position Q2 and have different emission sources, is operated. The control device 9 controls the permissible fluctuation range (for example, the permissible fluctuation range is within the range of plus or minus 10% centering on the more desirable total amount (equivalent to 100)). As long as the total amount is within the permissible fluctuation range, for example, the reduction start part of the contained material discharged from the storage device S1 * and the contained material discharged from the storage device S2 * reach together for the first time at position Q2. The time to do so does not have to coincide with the arrival time at which the increasing start portion of the contained material discharged from the storage device S2 * and the contained material discharged from the storage device S1 * first come together at position Q2. ..

If the total amount does not fall within the permissible fluctuation range, the computer program executed by the operation control device 9 or the operation control device 9 may be modified so that the total amount does not fall within the allowable fluctuation range. Change the transmission timing, delay time Pt [s2 *] in step s203, etc., (b) change the change over time in the amount of reduction of the contained material discharged from the storage device S1 *, (c) change the storage device S2 *. Adjustments are made, such as changing the change over time in the amount of increase in the contents discharged from the container. Regarding (b) on the left, for example, in the case where the change over time in the decrease in the amount of the contained material discharged from the discharge unit outlet of the storage device S1 * to the feeder in step s105 is discharged by the natural drop of the contained material. The emission control means is controlled so that the locus changes with the passage of time or changes in a step shape of one step or two or more steps, instead of a locus or a linear locus. Regarding (c) on the left, for example, in step s203, the change over time in the increase in the amount of the contained material discharged from the outlet of the storage device S2 * to the feeder is not a linear locus but the passage of time. The emission control means is controlled so that the locus changes with the inclination or changes in a step shape of one step or two or more steps.

(2-1-4) The amount of the items to be transported, which are the items to be contained that have been discharged from the outlet of the discharge unit of the storage device S1 *, and have been transported to the position Q2 by the feeder and the transfer device constituting the transfer path. At the stage where the value is reduced to zero or close to a predetermined value at that position, or after a predetermined period of time has elapsed, the discharge valve of the discharge unit is fully closed, whereby the reduction of the transported object at position Q2 is completed. (Step s109). On the other hand, the amount of the contained material discharged from the discharge unit outlet of the storage device S2 * and transported to the position Q2 by the feeder increased to 100 or a predetermined value close to 100 at that position. At the stage, the increase of the transported object at the position Q2 is completed (step s207).

The time of the end of the decrease in the items to be transported in step s109 is the end of the increase in the items to be transported in step s207 as long as the total amount of the items to be transported with different emission sources together at position Q2 is within the allowable fluctuation range. It does not have to match the time of.

(2-1-5) Thus, the switching of the emission source from the storage device S1 * to the storage device S2 * is completed through the steps s107 to s109 and the steps s205 to s207 at the position Q2 (step s110, step s208). ).

After that, in the storage device S1 *, the bridge prevention means and the feeder are stopped (process s111), and the replenishment of the contained material from the raw material receiving / supplying facility V is started (process s112).

(2-2) In FIGS. 12 and 13, the decrease in the amount of discharge from the storage device S2 * on the downstream side is compensated for by the discharge from the storage device S1 * on the upstream side, whereby the storage device S2 * to the storage device S1 It is a schematic explanatory diagram of an example of control for switching discharge to *. In each figure, (A) and (B) explain the control process related to the storage device S2 * and the control device S1 *, respectively.

(2-2-1) First, in the storage device S2 * on the downstream side, the feeder and other emission control means are in operation, and the emission valve of the discharge section is opened by the other emission control means. The contents to be contained in the accommodation unit are discharged from the outlet of the discharge unit toward the feeder, transported to the position Q2 by the feeder, and transported to the fuel combustion device 7 at the position Q2. It is transferred to the transport device that constitutes the route, and is transported to the final destination (fuel combustion device 7) on the downstream side via the position Q2 by the transport device (process s131). The amount of the object to be conveyed by the transfer device is assumed to be 100.

As the content to be contained is discharged from the outlet of the discharge unit, the residual level of the content to be contained in the storage unit decreases, and when the preset residual level A is reached, the level measuring device changes to the residual level A at that time. The corresponding signal A is transmitted (step s132). When the amount of objects to be contained in the storage device S2 * is further reduced and reaches the preset residual level B, at that time, the level measuring device transmits a signal B corresponding to the residual level B (step s133). ). The transmission destination of the signal A and the signal B is the operation control device 9.

The residual level A is the same level or higher than the residual level 1 in step s102 (a level reached in a shorter time from the start of withdrawal of the contained material from the discharge unit outlet). On the other hand, the residual level B is a higher level (a level reached in a shorter time from the start of discharge of the contained material from the discharge unit outlet) as compared with the residual level 2 in the step s103. This is because switching the emission source from the downstream storage device to the upstream storage device has less time to control than in the opposite case, so the step s233 described later is executed earlier. Because it is necessary.

After the contained material in the accommodating portion reaches the residual level B, the operation of the bridge preventing means is started (step s134). As in the case of the bridge prevention means in step s104, the timing of starting the operation of the bridge prevention means and the method of operating the bridge prevention means are particularly limited as long as the control purpose of switching the emission source of the contained object can be achieved. There is no.

The contents to be discharged from the discharge unit outlet to the feeder start to decrease, and continue to decrease (step s135), and are transported to the position Q2 by the feeder as in the case of step s131 before the start of the decrease. Then, it is transferred to the transport device constituting the transport path, and is transported toward the downstream side from the position Q2 by the transport device (process s136). Therefore, the contained material is transported in the order of the reduction start portion of the payout and the subsequent reduction portion, and reaches the position Q2 as the to be delivered (step s137, step s138).

(2-2-2) In step s135, measures to delay the decrease in payout amount are also implemented. The payout reduction delay measure means a measure for delaying the start and / or end of the payout of the contained material from the discharge unit outlet to the feeder, which is executed under the control of the operation control device 9. The payout reduction delay measure implemented in step s135 is, for example, when the measuring device detects that the initial payout amount (equivalent to 100) has reached a preset threshold value (tentatively equivalent to 90). By the amount control means (especially closing the discharge valve of the discharge part to some extent), the payout amount is forcibly reduced to a preset target value (assumed to be equivalent to 30), and the remaining amount of the contained material is zero or it. It is a measure to delay the end of the withdrawal of the contained object by maintaining the target value equivalent to 30 until the value becomes close to the value or a certain period of time elapses (see FIG. 14 (a)).

The operation of the bridge prevention means moves the clogging, stagnation, blockage, etc. of the contained material in the storage device S2 * into the discharge part, so that it also has the effect of delaying the start and end of the decrease in the amount of the contained material to be discharged. Play. Therefore, if the operation of the bridge prevention means started in the step s134 continues even at the time of the execution of the step s135, the operation of the bridge prevention means is the measure for delaying the payout reduction executed in the step s135. include.

The measures to delay the reduction of the payout amount eliminate or alleviate the lack of time in the control of switching the emission source.

(2-2-3) On the other hand, in the storage device S1 * on the upstream side, the discharge section outlet is initially fully closed, and the containment section is in a state where the contained material is replenished by the raw material receiving / supplying facility V, and the feeder. Is not operating (process S231), but based on the command signal transmitted from the operation control device 9 that received the signal A, the storage device S1 * is ready for operation, and after the preparation is completed, it waits for the next command signal. The state is reached and the operation of the feeder is started (process s232).

Next, in the storage device S1 *, based on the command signal transmitted from the operation control device 9 that has received the signal B, immediately after receiving the command signal or after the lapse of a predetermined delay time Pt [s1 *] following the reception of the command signal. The discharge valve of the discharge section is opened, the discharge of the contained material from the discharge section outlet to the feeder is started, and the discharge amount is increased (step s233). The opening degree of the discharge valve in the open state and the degree of increase in the amount of the contained material to be discharged (including the change over time) are adjusted by the discharge amount control means under the control of the operation control device 9. To.

The initiation of the increase in the amount of the contained material in step s233 and the subsequent increase are set by the emission control means so as to compensate for the start of the decrease in the amount of the contained material in the process s135 and the subsequent decrease as much as possible. Will be done. For example, the decrease in the payout amount in step s135 is due to the measure to delay the payout amount reduction, as shown in FIG. When 1] elapses, the threshold value equivalent to 90 is reached, immediately after that, it decreases to 30 equivalents, and then the payout amount equivalent to 30 is maintained until the time Pt [2] elapses. " Then, the increase in the payout amount in the step s233 is equivalent to "from zero to 10 from a certain reference time T0 [s1 *] to the elapse of the time Pt [1] as shown in FIG. 14 (b). It increases, and increases to 70 equivalent immediately after the passage of time Pt [1], and then the payout amount equivalent to 70 is maintained until Pt [2] elapses. " Under control, it is adjusted by emission control means.

The contained material discharged to the feeder is conveyed to the position Q1 by the feeder, transferred to the transfer device constituting the transfer path, and further transferred to the position Q2 by the transfer device (step s234). Therefore, the contained material is transported in the order of the increase starting portion of the payout and the subsequent increasing portion, and reaches the position Q2 as the transported object (step s235, step s236). For the first time at position Q2, the contained material is together with the contained material discharged from the storage device S2 * and is transported together by the same transport device toward the downstream side of position Q2.

(2-2-4) The total amount of the contained items discharged from the storage device S2 * and the contained items discharged from the storage device S1 *, which are combined at the position Q2 and have different emission sources, is operated. The control device 9 controls the permissible fluctuation range (for example, the permissible fluctuation range is within the range of plus or minus 10% centering on the more desirable total amount (equivalent to 100)). As long as the total amount is within the permissible fluctuation range, for example, the reduction start part of the contained material discharged from the storage device S2 * and the contained material discharged from the storage device S1 * reach together for the first time at position Q2. The time to do so does not have to coincide with the arrival time at which the increasing start portion of the contained material discharged from the storage device S1 * and the contained material discharged from the storage device S2 * first come together at position Q2. ..

If the total amount does not fall within the permissible fluctuation range, the remaining level B, the transmission timing of the signal B, by modifying the computer program executed by the operation control device 9 or in the operation control device 9 so as to be within the allowable fluctuation range. Change the delay time Pt [s1 *] etc. in step s233, (b) change the change over time in the amount of reduction of the contained material discharged from the storage device S2 *, (c) discharge from the storage device S1 *. Adjustments are made, such as changing the change over time in the amount of increase in the contents to be contained. Regarding (b) on the left, for example, in step s135, the change over time in the decrease in the amount of the contained material discharged from the outlet of the discharge unit of the storage device S2 * to the feeder is changed by implementing the measure to delay the decrease in the payout amount, or the change thereof. Independent of the execution, it is not a locus or a linear locus when the contained object is discharged by natural fall, but a locus whose inclination changes with the passage of time or changes in a step shape of one step or two or more steps. The emission control means is controlled so as to be. Regarding (c) on the left, for example, in step s233, the change over time in the increase in the amount of the contained material discharged from the discharge part outlet of the storage device S1 * to the feeder is not a linear locus but the passage of time. The emission control means is controlled so that the locus changes with the inclination or changes in a step shape of one step or two or more steps.

(2-2-5) The amount of the contained object discharged from the discharge part outlet of the storage device S2 * and conveyed to the position Q2 by the feeder is a predetermined amount of zero or close to zero at that position. When the value is reduced or after a predetermined period of time has elapsed, the discharge valve of the discharge unit is fully closed, whereby the reduction of the transported object at position Q2 is completed (step s139). On the other hand, the amount of the contained material discharged from the discharge unit outlet of the storage device S1 * and transported to the position Q2 by the feeder and the transport device constituting the transport path is 100 or 100 at that position. When the value increases to a predetermined value close to that, the increase of the transported object at the position Q2 ends (step s237).

The time of the end of the decrease in the items to be transported in step s139 is the end of the increase in the items to be transported in step s237 as long as the total amount of the items to be transported with different emission sources together at position Q2 is within the allowable fluctuation range. It does not have to match the time of.

(2-2-6) Thus, the switching of the emission source from the storage device S2 * to the storage device S1 * is completed through the steps s137 to s139 and the steps s235 to s237 at the position Q2 (step s140, step s238). ).

After that, in the storage device S2 *, the bridge prevention means and the feeder are stopped (process s141), and the replenishment of the contained material from the raw material receiving / supplying facility V is started (process s142).

After (2-3), the emission source is switched between the upstream storage device S1 * and the downstream storage device S2 * by the control described in (2-1) and (2-2) above. Is repeated smoothly.

[Second embodiment]
<Basic form>
(1) FIG. 15 is a block diagram of a basic form of the second embodiment. The fossil fuel alternative fuel transfer system W shown in FIG. 15 is shown in FIG. 5 when the vicinity of the position Nc is configured as [Z1] except for the position Nb and the downstream side of the position Nc (first). It is the same as the modification 4) of the embodiment, and when the vicinity of the position Nc has the configuration of [Z2], it is the same as that shown in FIG. 6 (modification 5 of the first embodiment).

In this transfer system W, (a) on the downstream side of the position Nb and the position Nc, the first transfer path L1 from the position Nb to the fuel combustion device 7 via the first crushing device 41 and the mixing device 42 in order. (Or, depending on the operation of the inheritance section J2 #, the second transfer path L2) and the devices constituting it (including the first crushing device 41 and the mixing device 42, but not the succession section J2 #), ( b) The second transport path L1 (or the successor J2 #) from the position Nc to the fuel combustion device 7 via the second crusher 51, the fourth inheritance J4 and the mixing device 42 arranged at the position Nd in order. Depending on the operation of, the first transport path L2) and the devices constituting it (including the second crushing device 51, the fourth succession section J4 and the mixing device 42, but not the third succession section J3), ( c) The second transport path L2 (or the successor J2 #) from the position Nc to the fuel combustion device 7 via the second crusher 51 and the fourth successor J4 in order and without passing through the mixing device 42. Depending on the operation of, the first transport path L1) and the devices constituting it (including the second crushing device 51 and the fourth succession section J4, but not the third succession section J3 and the mixing device 42), ( d) It has a route R1 that is a part of the third transport route L3 and its constituent devices, and (e) a route R2 that is a part of the third transport route L3 and its constituent devices. ..

The above (d) is the third transport path L3 and the third transport path L3 from the position Nc to the fuel combustion device 7 via the second crusher 51, the fourth successor J4 in order and without passing through the mixing device 42. (Including the second crushing device 51 and the fourth succession section J4, but not including the third succession section J3 and the mixing device 42), and the above (e) is the second crushing device from the position Nc. A third transport path L3 leading to the fuel combustion device 7 via the device 51, the fourth succession section J4, and the mixing device 42, and the devices constituting the third transfer path L3 (second crushing device 51, fourth succession section J4, and mixing device). It includes the device 42, but does not include the third successor J3).

If the succession unit J2 # transfers or transfers the fossil fuel alternative fuel only to the equipment that constitutes the transport route via the first crushing device 41, the third succession unit J3 shall be the third. The fossil fuel alternative fuel is not inherited or transferred to the equipment constituting the transport device L3), and only the fossil fuel is input to the second crushing device 51, where it is crushed, and the fourth succession section J4 on the downstream side. Further transported towards. When the inheritance unit J2 # inherits or transfers the fossil fuel alternative fuel only to the equipment that constitutes the transfer route (between the position Nb and the position Nc) that does not pass through the first crushing device 41. , The third succession unit J3 transfers or transfers the fossil fuel substitute fuel to the device constituting the third transfer device L3), and the fossil fuel and the fossil fuel substitute fuel are mixed and the second crusher. It is charged into 51, crushed there, and further transported toward the fourth successor J4 on the downstream side.

When the fossil fuel and the fossil fuel alternative fuel are put into the second crushing device 51 in a mixed state and crushed there, the mixing of both substances proceeds. Considering this point, it can be said that the second crushing device 51 corresponds to the crushing / mixing device.

The fourth succession unit J4 is for selectively transferring the transported object discharged from the second crushing device 51 and transported to the position Nd to the device constituting either the path R1 or the path R2. It has a mechanism. As for the mechanism, a known one may be sufficient as in the mechanism of the inherited portion J2 #.

It reaches the fuel combustion device 7 via or through the fourth inheritance section J4, and therefore shares the second crushing device 51 and the fourth succession section J4, and reaches the position Nc and the fuel combustion device 7. A part of the second transport path L2 (or the first transport path L1) and the third in the range downstream of the second crusher 51, that is, between the second crusher 51 and the fuel combustion device 7. A part of the transport path L3 forms a shared path, and shares the devices (excluding the second crushing device 51 and the four inheritance section J4) that make up the shared path. Further, the second transport path L2 (or the first transport path L1 depending on the control by the operation control device 9) and the third transport path L3 both pass through or pass through the mixing device 42 to be a fuel combustion device. 7 is reached, and therefore the mixing device 42 is shared, and moreover, it is a part of the second transport path L2 (or the first transport path L1) in the range between the mixing device 42 and the fuel combustion device 7. A part of the third transport route L3 forms a shared route, and shares the devices (excluding the mixing device 42) constituting the shared route.
Therefore, this transport system W has a simpler configuration that can avoid an increase in equipment cost.
