What is the function of a boiler feed pump?

The function of a boiler feed pump is primarily to supply water to the boiler to compensate for the steam that is produced and for any losses that occur throughout the system. As steam is generated, water is converted into vapor, which leads to a decrease in the level of water within the boiler. To maintain operational efficiency and safety, the feed pump ensures that the boiler is continually supplied with the necessary amount of water. This process helps sustain the correct water level for optimal steam generation, thereby supporting the overall performance and reliability of the boiler system.
