給水温度制御装置。 By controlling the water supply temperature at the economizer inlet of an exhaust gas boiler that guides exhaust gas from a gas turbine, etc. and uses its heat to generate steam, the circulating flow rate of drum water to the economizer inlet is adjusted using a circulation flow rate control valve. In the device for controlling the temperature to a set value, means for outputting the temporal rate of change of the boiler inlet exhaust gas temperature, means for outputting the temporal rate of change of the boiler steam pressure, and means for outputting the temporal rate of change of the boiler inlet exhaust gas temperature and the boiler steam pressure. an exhaust gas boiler feed water temperature control device, comprising means for adding the temporal change rate to the opening degree command of the circulation flow rate control valve.
