Document Type and Number:
WIPO Patent Application WO/2021/010411
Kind Code:
A1
Abstract:
This control system (3) is for controlling the amount of reducing agent to be injected into the exhaust gas flowing from a coal-fired boiler (5) in a thermal power generation facility to a denitration reactor (41) in a denitration device (31), and comprises: a first prediction unit that predicts a first concentration, which is the concentration of nitrogen oxides in the exhaust gas flowing toward the denitration reactor, on the basis of first operation data, which is the operation data of the thermal power generation facility; and a control device (51) that controls the injection amount on the basis of the predicted value of the first concentration predicted by the first prediction unit. The first operation data includes at least one of second operation data, which is the operation data of one or more pulverized coal machines (12) provided in the thermal power generation facility, and third operation data, which is operation data of the coal-fired boiler affected by variations in the operation conditions of the one or more pulverized coal machines (12).
