Boiler Feed Pump - an overview | ScienceDirect Topics

For recirculation flow of a BFP (the pump has its suction from the deaerator), the pump entire/partial flow water from the BFP is returned to the deaerator during startup and at low load. Generally, the BFP handles the high flow at high differential pressure (DP); the pump sizes are large so even for small units such recirculation flow is necessary.
