What role does a feedwater pump play in relation to a boiler?

The feedwater pump is essential for maintaining the necessary water level in a boiler system. It moves water from the feedwater system into the boiler, ensuring that there is enough water to produce steam and maintain proper operation. If the water level drops too low, it can lead to overheating and damage to the boiler, while too high a water level can result in water being carried over into the steam system, which can cause various operational problems. Thus, the feedwater pump directly contributes to the safety and efficiency of the boiler by managing the appropriate water level needed for steam generation.
