Silica Removal from Water by Ion Exchange - Pure

Silica Ion-Exchange system can complement any water treatment system if there is a need to remove the silica from water specifically. If the water contains silica and other unwanted ions and water purity is also an importance, then a Continuous Deionizing system is much more appropriate. /custom-features custom-usage High Pressure Boilers

The Importance of Boiler Water and Steam Chemistry

Often, for low pressure building or process heater steam, only a maximum moisture content is specified. This may be as high as 0.5% or as low as 0.1%. Conversely, some turbine manufacturers specify steam condensate maximum cation conductivity, pH, and maximum concentrations for total dissolved solids, sodium and potassium, silica, iron and copper.

silica in high pressure boilers - ferienwohnungeising.de

A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.

Prediction of silica carry-over and solubility in steam

High boiler water silica content can result in silica (SiO 2) vaporization with the steam, and under certain circumstances, siliceous scale. A novel and robust correlation was developed to predict the silica solubility in steam of boilers as a function of pressure and water silica content.
