[0014] [Figure 1] 1 is an overall schematic configuration diagram showing an embodiment of a fuel operation system for a power generation facility according to the present invention; [Figure 2] 1 is a flowchart illustrating an embodiment of a fuel operation system for a power generation facility according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0016] 1 and 2 show the power generation equipment of the present invention. Fuel Management System This is an example of the above.

[0017] 1, in the fuel operation system of this embodiment, a power generation facility 10 includes a boiler 20, and coal as fuel stored in a storage facility 30 is transported to a bunker 50 by a transport device 40 and combusted in the boiler 20. Note that biomass may be mixed with the coal from a bunker (not shown) and combusted in the boiler 20.

[0018] The fuel stock information I, including the fuel type (coal type), stock amount, storage location, storage calories, storage period, and planned fuel receiving amount of the coal stored in the storage facility 30, is continuously managed by the management computer 60.

[0019] The required power generation amount M of the power generation facility 10 is input to the management computer 60, and based on the stored fuel information I and the required power generation amount M, the management computer 60 determines the storage facility 30 for coal that should be consumed preferentially and the required amount of coal, and creates a transportation schedule S from the storage facility 30 to the bunker 50 based on the determined storage facility 30 and required amount of coal. When coal and biomass are used as fuel, the mixing ratio between them is set and the required amount of each is determined.

[0020] The transfer schedule S created by the management computer 60 is output to the control device 70, and the control device 70 outputs an automatic operation command A to the transfer device 40 based on the transfer schedule S.

[0021] The transport equipment 40 is, for example, a reclaimer 40a, a belt conveyor 40b, a damper 40c, and the like.

[0022] The reclaimer 40 a discharges coal from the storage facility 30 .

[0023] The belt conveyor 40b transports the coal discharged by the reclaimer 40a to a bunker 50.

[0024] The damper 40c changes the route of the coal transported by the belt conveyor 40b.

[0025] Incidentally, when creating the transport schedule S, the reclaimer 40a to be operated, its dispensing start and end positions (dispensing range), dispensing amount [tons / h], and operation start and end times are clarified from the storage facility 30 for coal that should be consumed preferentially and the required amount of coal, so the movement of the reclaimer 40a, the operation of the boom, etc. can be determined, and once the reclaimer 40a to be operated is determined, the belt conveyor 40b and damper 40c to be operated and their operation start and end times can also be determined.

[0026] In the example shown in Figure 1, coal as fuel transported by ship 80 is unloaded by unloader 90 and transported by belt conveyor 40b, and the coal transported by belt conveyor 40b is delivered to storage facility 30 by reclaimer 40a, which also serves as a stacker.

[0027] As shown in FIG. 2, the fuel management method of this embodiment includes a process for acquiring and managing information on available fuel, a process for inputting required power generation, a process for determining fuel consumption, a process for creating a transport schedule, and a process for carrying out transport.

[0028] The stored fuel information acquisition and management step is a step of continuously managing stored fuel information I including fuel type (coal type), stored amount, storage location, stored calories, possible storage period, and planned fuel receiving amount.

[0029] The required power generation amount input step is a step in which the required power generation amount M is input.

[0030] The fuel consumption determination process is a process in which the storage facility 30 for coal that should be consumed preferentially and the required amount of coal are determined based on the held fuel information I managed in the held fuel information acquisition and management process and the required power generation amount M input in the required power generation amount input process.

[0031] The transportation schedule creation step is a step of creating a transportation schedule S from the storage facility 30 to the bunker 50 based on the storage facility 30 and the required amount of coal determined in the fuel consumption determination step.

[0032] The transport implementation step is a step of transporting coal to a bunker 50 by the transport equipment 40 based on the transport schedule S created in the transport schedule creation step.

[0033] Next, the operation of the above embodiment will be described.

[0034] Coal as fuel is transported by ship 80, unloaded by unloader 90, transported by belt conveyor 40b, and delivered to storage facility 30 by reclaimer 40a, which also serves as a stacker. The stored fuel information I, including the fuel type (coal type), amount stored, storage location, retained calories, possible storage period, and planned amount of fuel received for the coal stored in storage facility 30, is continuously managed by management computer 60 (see the stored fuel information acquisition management process in Figure 2).

[0035] The required power generation amount M of the power generation facility 10 is input to the management computer 60, and based on the stored fuel information I and the required power generation amount M, the management computer 60 determines the coal storage facility 30 to be preferentially consumed and the required amount of coal (see the consumed fuel determination process in Figure 2). When coal and biomass are used as fuel, their mixing ratio is set and the required amount of each is determined.

[0036] The management computer 60 creates a transport schedule S from the storage facility 30 to the bunker 50 based on the determined storage facility 30 and the required amount of coal (see the transport schedule creation process in FIG. 2). The transport schedule S includes information on which reclaimer 40a, which belt conveyor 40b, and which damper 40c should be operated as transport equipment 40, and when.

[0037] The transport schedule S created by the management computer 60 is output to the control device 70, and based on the transport schedule S, an automatic operation command A is output from the control device 70 to the transport equipment 40, and the transport equipment 40 transports the coal to the bunker 50 (see the transport implementation process in Figure 2).

[0038] Incidentally, a command including the dispensing start and end positions (dispensing range), dispensing amount [ton / h], and operation start and end times is output as an automatic operation command A to the reclaimer 40a that should be operated as the conveying equipment 40. Also, a command including the operation start and end times is output as an automatic operation command A to the belt conveyor 40b and damper 40c that should be operated.

[0039] As a result, in this embodiment, it is possible to process the planning of operation plans for the entire power generation facility 10, the planning of operation plans for each individual conveying device 40, and the actual operation of the conveying device 40 as a series of steps on a consistent system, so the actual operation of the conveying device 40 is not left to the person in charge and there is no need for humans to intervene in individual tasks, eliminating the need to worry about stagnation in the use of coal as fuel for the power generation facility 10 or communication or operational errors.

[0040] Furthermore, the individual interfaces (for example, operation buttons and displays) that are currently essential for the operation of the conveying equipment 40 can be replaced by simply providing centralized control interfaces, which makes it possible to significantly reduce the costs required for designing, manufacturing, and installing individual interfaces as well as the costs required for regular maintenance.

[0041] In this way, delays and errors in the use of coal as fuel can be eliminated and costs can be reduced.

[0042] In addition, the power generation equipment of the present invention Fuel Management System The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. [Explanation of symbols]
