却水供給装置。In a cooling water supply system for a desuperheater in a steam power plant that supplies pressurized cooling water using a condensate pump to the desuperheater of the turbine bypass equipment to reduce the temperature of the turbine bypass steam; isolated operation within the plant. The deaerator water level control valve is temporarily closed when the required amount of cooling water increases rapidly such as when a unit trip occurs or when a unit trip occurs, thereby avoiding a drop in the condensate pump discharge pressure. Cooling water supply device for desuperheater.
