Boiler Chemistry Control and Treatment of Feed Wate

Silica from CW is another damaging factor as it deposits on turbine. Silica needs to be controlled at DM plant also. The percentage of impurity allowed in boiler water/steam is function of boiler operating pressure, so, more critical for high pressure boilers.

Prediction of silica carry-over and solubility in steam

Silica content of the boiler water is critical for steam turbines and scaling of boiler heat transfer surfaces. Silica (SiO 2) can volatilize with the steam in sufficient concentrations to deposit in steam turbines leading to scale formation on boiler surfaces.In this work, a simple correlation is presented to predict silica (SiO 2) solubility in steam of boilers as a function of pressure and

Boiler Water Treatment - Why is It Importa

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.
