WebFormation of deposits: Scale and sludge formation. Scale:If the precipitate forms hard and adherent coating on the inner walls of the boiler is known as scale. It is formed by the substances like CaSO4, Mg (OH)2 and Ca (HCO3)2. Scales are difficult to remove even with the help of hammer and chisel. Scales are the main sources of boiler troubles. WebElements contained in hard water, like calcium and magnesium, form a buildup on the components of the boiler. Preventing this damaging accumulation of hard water deposits is crucial to maintaining the effectiveness of a boiler.
