    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.
