Boiler Feed Pump - an overview | ScienceDirect Topics

The BFP recirculation line is taken from the pump discharge ahead of the discharge valve and returned through the recirculation valve to a deaerator where the BFP has suction (see Figure III/6.2-1 and III/6.2-2).There are various BFP sizes, types, and unit sizes, as well as variations in controls.
