Corrosion protector

The affinity of some metals in a corrosive environment initially increases normally with increasing concentration of corrosive agents (oxidizing power of the solution), and metal corrosion is intensified, but at a certain concentration of corrosive agents, the corrosion rate suddenly decreases significantly and the metal loses its affinity and becomes inactive. The reason for the reduction in corrosion at a certain concentration of oxidizing components is the formation of a protective or inactive layer on the metal surface. The protective layer can be oxide, hydroxide or other compounds. This phenomenon is called rusting.

Steam boilers are mainly made of carbon steels, and the internal surface of these metals that are in contact with water must be free of deposits. Deposits have a lower thermal conductivity than metals, which causes the temperature of the metal to rise on the combustion wall side. Therefore, more fuel is needed to produce steam. Therefore, there is a need to control and wash these deposits inside the steam boiler.
