Title:
BOILER COMBUSTION CONTROL SYSTEM AND BOILER COMBUSTION CONTROL METHOD FOR SUPERCRITICAL PRESSURE ONCE-THROUGH BOILER AND ULTRA SUPERCRITICAL PRESSURE ONCE-THROUGH BOILER
Document Type and Number:
WIPO Patent Application WO/2022/208846
Kind Code:
A1
Abstract:
A boiler combustion control system 301 comprises: a load demand correction unit 310 that, on the basis of a total fuel flow rate FRR and a water-fuel ratio master signal WFR for performing control so that the water-fuel ratio defined by the weight ratio between the amount of water supply to a boiler and the fuel input amount has a prescribed value, corrects a load demand MWD' after feedback correction and calculates the load demand after correction based on the total fuel flow rate FFR and the water-fuel ratio master signal WFR; and a fuel correction factor calculation unit 14 that calculates a fuel correction factor K on the basis of the ratio between a load demand MWD before feedback correction and the load demand after correction based on the total fuel flow rate FFR and the water-fuel ratio master signal WFR.
