estimation of boiler feed water

feed water to coal boiler – Industrial Boiler

Estimation of Scale Deposition in the Water – SpringerLink Boiler scales are caused by impurities carried by boiler feed water and get precipitated on heat transfer surfaces. The deposition of crystalline precipitates on the walls of the boiler interferes with heat transfer and may cause hot spots, leading to local overheating.
