Description

  The present invention relates to a thermal power generation system that automatically generates a fuel consumption rate using process data (steam generation amount and fuel consumption amount) in a thermal power generation facility such as a thermal power plant that is operated and managed using the fuel consumption rate. The present invention relates to an automatic fuel intensity generation system and an automatic fuel intensity generation apparatus for equipment.

  The basic unit of fuel in the conventional thermal power plant is calculated from the planned steam flow rate and the planned fuel flow rate at the design point, and thereby the fuel procurement plan and the power generation plan are performed. On the other hand, the fuel consumption rate is not constant because it fluctuates due to changes in the performance of boilers, etc. over time, and changes in temperature. In order to expect highly accurate operation, it is necessary to revise the fuel consumption rate every time. is there.

The turbine 6 rotates, and the generator 7 is rotated by the rotation of the turbine 6, and the generator 7 generates electric power 8. The used steam 9 is collected separately.

  The fuel consumption 11 is input from the supplied fuel 2 via the fuel consumption detector 2S, and the steam generation 12 is input from the generated steam 5 via the steam generation detector 5S to the control device 20, respectively. Outputs control signals for condition monitoring and control of generated steam pressure.

  Here, conventionally, a fuel procurement plan and a steam generation plan are performed by the fuel intensity unit formula 15 of FIG. 9 established at the time of the design planning, and the operation of the power plant is carried out. Then, if it is considered that the plan and the actual result are different from each other, as shown in FIG. 9, the current value for manual calculation obtained from the current fuel consumption 11 and the current steam generation 12 is obtained. By manually creating the current fuel consumption rate equation 21 by manually marking the operation result data 16 on the graph, the fuel consumption rate equation 15 formulated at the time of design planning was reviewed.

  Although not directly related to the generation of fuel unit of a thermal power plant, Japanese Patent Application Laid-Open No. 2002-286289 (Patent Document 1) is known as a cogeneration apparatus, a user support system thereof, and a cogeneration apparatus with a user support system.
