Question: 1 / 400

What is the function of a feedwater pump?

To pump steam out of the boiler

To supply water to the boiler at the required pressure and flow rate

The function of a feedwater pump is critical in maintaining the operation of a boiler. It is designed to supply water to the boiler at the required pressure and flow rate, which ensures that the boiler has the necessary water volume for steam generation. This supply is essential because as water is converted to steam within the boiler, it is continuously lost through steam production and the system's operation. Therefore, the feedwater pump helps to replenish this water, allowing the boiler to maintain its efficiency and productivity without interruption.

The proper functioning of the feedwater pump is essential for boiler safety and efficiency; if it fails to deliver adequate water, the boiler may run dry, leading to overheating and potential damage. This makes the feedwater pump a vital component in the boiler system.
