how scale and sludge are produced in a steam boiler

Formation of scales may be due to; (1) Decomposition of calcium bicarbonate. Ca (HCO3)2 → CaCO3 ↓ + H2O + CO2 ↑. Scale. However, scale composed chiefly of calcium carbonate is soft and is the main cause of scale formation in low-pressure boilers. But in high-pressure boilers, CaCO3 is soluble. CaCO3 + H2O → Ca (OH2)2 (soluble) + CO2 ↑.

Prevention of Corrosion and Scale Formation in Steam Boilers

Elements 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. Hard scale buildup, even a seemingly insignificant one of 1/8 of an inch, can reduce efficiency by up to 20-25% due to
