Boiler Water Treatment - Why is It Important

Boiler water quality is of prime concern to all boiler operators. The process of water treatment in boilers is not limited to producing high quality DM water. The stringent water chemistry requirements of Supercritical power plants makes water treatment in boilers a very critical aspect of power plant operation. This necessitates the use of a high quality water treatment system.

Standard Test Method for Low-Level Total Silica in

5.1 Control of silica in boiler feedwater and boiler water is necessary to minimize the formation of scale-forming silicates that decrease heat transfer in the boiler. Volatilization and carryover of silica with the steam may cause hard, glassy siliceous deposits to form on turbine blades that reduce turbine efficiency.

Boiler Feedwater Treatment (Part I): Why Water

2015-8-20 · Boiler water carryover is the contamination of steam with boiler water solids. Common causes of boiler water carryover are: Bubbles or foam form on the surface of the boiler water and leave with the steam. This is due to high concentrations of insoluble or soluble solids in the boiler water.
