制御装置。In a boiler that detects the superheater outlet temperature and adjusts the amount of spray injected into the superheated steam by the spray control valve opening command, a pressure sensor is installed to detect the pressure in the steam water separator drain tank, and the The difference between the value obtained by converting the pressure signal into a temperature signal plus the allowable temperature range and the value of the furnace pass outlet temperature detected by the furnace pass outlet temperature sensor installed at the furnace pass outlet is used as a spray control valve opening correction command. A furnace path outlet temperature control device for a boiler, characterized in that a circuit for adding to the spray control valve opening degree command is provided.
