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 …Get Price
The boiler is a closed vessel, where the water is stored. Hot gases are formed by burning fuel in the furnace. These gases are made to come in contact with the water vessel, the point where the heat transfer takes place between the steam and water. Thus, the boiler's basic principle is to convert water into steam with heat energy.Get Price
