What common issue can arise in boiler systems due to improper feedwater treatment?

Excessive scaling on surfaces is indeed a common issue that can arise in boiler systems as a result of improper feedwater treatment. When feedwater is not treated correctly, it may contain a high concentration of minerals, such as calcium and magnesium. These minerals can precipitate out of the water when heated, leading to the formation of scale on the heat transfer surfaces within the boiler.

This scale acts as an insulating barrier, reducing the efficiency of heat transfer. As a result, the boiler requires more energy to produce the same amount of steam, leading to increased fuel consumption and operational costs. Furthermore, the scale can reduce the flow of water and steam, potentially causing overheating of the boiler components, which can ultimately lead to equipment failure and increased maintenance needs.

Proper feedwater treatment is essential to minimize these risks by controlling the concentrations of minerals and preventing scale formation, ensuring efficient boiler operation and longevity.
