Why is it necessary to treat industrial boiler water with soft water

If the water quality for industrial boilers is not good, it can have various impacts.

Firstly, poor water quality may cause boiler fouling. The large amount of salt components contained in water, such as calcium, magnesium, phosphorus, etc., can form scale on the surface of the boiler. The poor thermal conductivity of scale can affect the heat transfer of the boiler, resulting in incomplete transfer of heat released from fuel combustion to the boiler water, resulting in a large amount of heat loss.

Secondly, corrosion may also be exacerbated by poor water quality. The components of the boiler, such as the economizer, water-cooled wall, convection tube bundle, and drum, can cause corrosion due to poor water quality. Corrosion can cause metal components to become thinner, concave, or even perforated, and in severe cases, it can damage the internal structure of the metal, leading to a significant decrease in its strength. This not only seriously affects the safe operation of the boiler, but also may shorten the service life of the boiler.

In addition, the corroded metal surface is prone to generating metal corrosion products, such as iron oxides. After these corrosion products are brought to the heating surface of the boiler by the boiler water, they are easy to form scale with other impurities. When this scale contains iron, the heat transfer effect will be worse.

Overall, poor water quality for industrial boilers can have multiple impacts, including boiler fouling, corrosion, and the resulting decrease in thermal efficiency and economic losses. Therefore, it is necessary to strictly monitor and improve the water quality of boiler water.
