とするボイラー圧力制御装置。 The fuel flow rate is controlled by adding the feedforward signal related to the main steam flow rate to the operational output obtained by controlling and calculating the deviation between the main steam pressure measurement value of the boiler and the main steam pressure set value related to the main steam flow rate. A boiler pressure control device for calculating a boiler master signal for a boiler pressure control device, wherein the feedforward signal is corrected based on an enthalpy value determined by the temperature and pressure of the main steam.
