Minimum flow circulation valve is the key supporting equipment of power plant’s boiler feedwater pump.

Boiler water from the feedwater pump will be pressurized up to 20-30Mpa or above in the deaerator then sent to the high pressure heater and eventally into the boiler. A certain minimum flow quantity of the feedwater pump should be ensured to take away the heat generated by its operation so as to avoid overheating and damage of vanes due to cavitation. Boiler feedwater flow is small during the startup and shutdown process while the water demand decreases in condition of breakdown. In order to ensure the normal operation of the pump, a recirculation system should be mounted in the pump outlet to carry a portion of the feedwater back to the deaerator from the pump.
