History of feedwater treatment. During the early development of boilers, water treatment was not so much of an issue, as temperatures and pressures were so low that high amounts of scale and rust would not form to such a significant extent, especially if the boiler was “blown down”. It was general practice to install zinc plates and/or alkaline chemicals to reduce corrosion within the boiler. Corrosion of the water side of the boiler may occur in three ways, by oxidation, by electrolytic dissolution and by acid attack. The boiler corrosion process is essentially an oxidationl reduction reaction. It may .   THERMAX LIMITED LIMITATIONS OF AVT • Primarily used in Power boilers where make water is 99% steam condensate (Pure water) • High purity Feed water is mandatory – MB-DM Make up and non-contaminated condensate • Increases load on CPU and reduces life of Resin • Excess level of Ammonia – accelerate Copper corrosion • Low boiler.
