Boiler - Wikipedia

A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications,[1][page needed][2][page needed] including water heating, central heating, boiler-based power generation, cooking, and sanitation.

Boiler Feed Pump - an overview | ScienceDirect Topics

To ensure the safety of large pumps, e.g., boiler feed pump (BFP), condensate extraction pump (CEP), etc., it is essential to maintain a minimum flow through the pump at all modes of operation. This control valve is located on a separate line tapped from either the individual pump discharge or the common discharge header of pumps.
