Abstract

PURPOSE: To reduce generation of corrosive products by providing a blow pipe that connects the bottom of a feed water heater and a dump pipe, and the means by which a blow valve is operated in the condition so that the drain in the feed water heeater is hot water.
CONSTITUTION: Ordinarily, a solenoid valve 26 communicates from A to B by the signal of a water level regulator 14, and communicates to the dump valve 12 side. When it becomes necessary to blow the drain, the solenoid valve 26 gives priority to the signal of blow pipe 25 open over the signal of the water level regulator 14, and forcibly operates the closed dump valve 12 to open by interlocking through communicatng B and C. Consequently, the drain that does not pass through a drain cooler 15 within a feed water heater 7 is recovered in a state of warm water. Priority selecting operation of the solenoid valve 26 is executed by a setting and regulating device of air signal.
