What is the function of a feedwater pump?

The function of a feedwater pump is to supply water to the boiler at the required pressure. In a steam boiler system, maintaining the correct water level and pressure is crucial for safe and efficient operation. The feedwater pump is responsible for delivering water into the boiler, ensuring that it is available to generate steam. This pump operates against the pressure in the boiler and must be capable of providing water at the necessary flow rate and pressure to match the steam generation demands.

The other options describe functions that do not pertain to the primary role of the feedwater pump. For example, removing excess steam from the boiler involves pressure management and safety systems, while cooling components relates to temperature regulation in a different capacity. Recycling water from the steam system may involve condensate return systems, which is distinct from the direct function of supplying water to the boiler. Thus, the correct understanding of the feedwater pump's role is critical for managing boiler efficiency and safety.
