1/1/2015 · When the boiler pressure is increased, silica volatilizes into steam and deposits on turbine blades. Steam, being a solvent for silica, selectively picks up silica from the feedwater. The dielectric constant (responsible for water to be a solvent) of water decreases with increase in temperature (ε = 78 at 25 °C, and ε = 18 at 300 °C).
