What is the primary function of a feedwater pump?

The primary function of a feedwater pump is to supply water to the boiler. In a steam generation system, the boiler requires a continuous supply of water to convert into steam. The feedwater pump takes water from the feedwater tank or a condenser and pumps it into the boiler at the required pressure. This process is critical in maintaining the necessary water level in the boiler to ensure efficient operation and prevent overheating or damage due to low water levels.

Other options do not directly represent the function of the feedwater pump. While pressure reduction is important in boiler operation, it is typically managed by other components, like pressure regulators or valves. Removing sludge and sediment may be part of water treatment processes or maintenance schedules, but is not the direct role of a feedwater pump. Maintaining system temperature can be a part of the broader heating cycle, but again, that is not the primary task of the feedwater pump; its focus is on supplying the right amount of water to the boiler at the required conditions.
