If these so-called alkaline earth metals are present in the feed water, they can precipitate due to the heating in the boiler and form limescale which is deposited as a layer on the heating surfaces. If the formation of a layer or coating is not identified early on, this will lead to a deterioration in efficiency because the heat transfer is restricted.

Boiler water treatment has basically two phases: First, we remove impurities from the water to the desired cleanliness. Second, we add chemicals to the feedwater to adjust the pH, create less favorable conditions for deposition, and remove oxygen. Special water treatment chemicals are used in almost all boilers.
