Question: 1 / 400

In a boiler system, what is "feedwater"?

Water that is condensed from steam

Water supplied to a boiler for steam conversion

Feedwater refers to the water that is supplied to a boiler for the purpose of being converted into steam. In a boiler system, the feedwater is essential as it serves as the primary raw material for steam production. The quality and treatment of feedwater are critical because impurities can lead to scaling, corrosion, and operational inefficiencies.

In the context of boiler operations, this water may come from various sources, such as condensate return systems, makeup water supplies, or demineralization processes, among others. The feedwater is carefully treated and often heated prior to entering the boiler to maximize efficiency and minimize the potential for damage to the boiler components.

Recognizing this definition helps in understanding the importance of proper feedwater management, which is vital for maintaining the overall performance and longevity of a boiler system.
