Boiler water treatment - Lenntech

Chemical treatment of water inside the boiler is usually essential and complements external treatment by taking care of any impurities entering the boiler with the feed water (hardness, oxygen, silica, etc.). In many cases external treatment of the water supply is not necessary and the water can be treated only by internal methods.

Corrosion in boilers - Lenntech

Corrosion is the reversion of a metal to its ore form. Iron, for example, reverts to iron oxide as the result of corrosion. The process of corrosion, however is a complex electro chemical reaction and it takes many forms. Corrosion may produce general attach over a large metal surface or it may result in pinpoint penetration of metal.

Boiler Corrosion – Tandex

2020-4-30 · Boiler corrosion is the active destruction of sound boiler metal by the pitting action of dissolved oxygen in the boiler water. This usually results in deep holes in the metal which are self protected by further corrosion products ie scabs or blisters over the hole which allow the chemical reaction to continue.
