One of the main causes of reduced reliability in boiler systems is corrosion. This phenomenon is described as the active destruction of sound boiler metal by the unforgiving action of dissolved oxygen in the boiler water. It usually results in deep holes, scabs, or blisters that allow the chemical reaction to continue. Even though large metal surfaces can be quite sound, an oxygen pitting site can develop deep corrosion and cause ultimate boiler failure. Untreated feed water containing oxygen ...
