Title:
BOILER COMBUSTION CONTROL SYSTEM AND BOILER COMBUSTION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/054193
Kind Code:
A1
Abstract:
A boiler combustion control system according to a typical embodiment of the present invention supplies a boiler with fuel corresponding to the amount of fuel input to the boiler calculated on the basis of a predetermined fuel function for the amount of load demand, calculates the amount of feedback correction on the basis of the measured main steam pressure, which is the measured main steam pressure of the boiler, and the preset main steam pressure, which is the main steam pressure of the boiler set in advance, and outputs a fuel correction factor for correcting the amount of load demand or fuel input after feedback correction to a plant that corrects the amount of load demand or fuel input on the basis of the feedback correction amount. This boiler combustion control system comprises a boiler combustion state calculation unit that calculates an index representing the effect of correcting the amount of fuel input to the boiler.
