What is an essential characteristic of boiler feedwater?

Boiler feedwater is crucial for the efficient operation and longevity of a boiler system. An essential characteristic is that it must be free of excessive minerals and impurities to prevent scaling. High levels of minerals and impurities, such as calcium, magnesium, and silica, can accumulate inside the boiler, leading to scaling on the heat transfer surfaces. This scaling acts as an insulating barrier, reduces the boiler's thermal efficiency, and can lead to overheating of the boiler components. Moreover, excessive impurities can also lead to other issues like corrosion and water quality problems. Therefore, maintaining the quality of the boiler feedwater is vital for optimal function and maintenance of industrial boiler systems.
