  • "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 (SiO2) 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 (SiO2) solubility in steam of boilers as a function of pressure and

  • The Effects of Silica on Steam Turbines | Sciencing

    Steam turbines are machines that convert the heat energy of steam from a water boiler into rotary motion. Their interior consists of a series of blades that capture the steam and provide a rotational force. As it rotates within a magnetic field, the turbine generates electric power. This principle constitutes 80

  • Boiler Feedwater Treatment (Part I): Why Water

    2015-8-20 · Boiler feedwater. Boiler 'feedwater' is the water supplied to the boiler. Often, steam is condensed and returned to the boiler as part of the feedwater. The water needed to supplement the returned condensate is termed 'make-up water'. Make-up water is usually filtered and treated before use.
