装置。A drain discharge system is installed between the feed water heater and the next stage feed water heater to detect the drain water level in the feed water heater that exchanges heat with boiler feed water or reactor feed water into which steam such as steam turbine oil or gas is introduced. Preliminary control that detects the turbine load, turbine extraction pressure, or feed water flow rate and predicts changes in the drain water level of the feed water heater due to load fluctuations, in a device equipped with a means for controlling a valve to maintain a normal drain water level. A drain water level control device for a feed water heater, comprising means for controlling the drain discharge valve in advance by the advance control means.
