Webbsludge deposits that precipitated elsewhere and were transported to the metal surface by the flowing water; Scale is formed by salts that have limited solubility but are not totally insoluble in boiler water. These salts reach the deposit site in a soluble form and precipitate when concentrated by evaporation. WebbIf the precipitate is loose and slimy it is called sludge. Sludge is formed by substances like MgCl2, MgCO3, MgSO4 and CaCl2. Sludge has greater solubilities in hot water than cold water. Scale 1) If the precipitate forms hard and adherent coating on the inner walls of the boiler, it is called scale.
