Which of the following best describes the purpose of a boiler feed pump?

The purpose of a boiler feed pump is fundamentally to supply water to the boiler at the required pressure. This is crucial because boilers operate under specific pressure conditions to ensure efficient steam generation. The feed pump takes water from the feedwater system, which can come from condensate return or external sources, and elevates it to the necessary pressure for it to enter the boiler.

Maintaining the correct pressure is vital for the effectiveness and safety of the boiler operation. If the pressure is too low, the boiler may not be able to generate steam effectively, leading to potential operational issues. Conversely, too high of a pressure can also lead to safety hazards. Thus, the feed pump is designed to precisely manage this aspect of the system, ensuring optimal conditions for steam production.

While options that mention cooling feedwater, increasing water temperature, or removing impurities might describe functions related to water handling and treatment in other contexts, they do not reflect the primary role of the boiler feed pump. The pump’s main function is strictly related to pressure management to ensure efficient boiler operation.
