Boiler Water - an overview | ScienceDirect Topics

Silica content of the boiler water is not as critical for steam systems without steam turbines. Iron occasionally in high pressure boilers where the iron content is high in relation to total solids blowdown may be based upon controlling iron concentrations. High concentrations of suspended iron in boiler water can produce serious ...

(PDF) Prediction of silica carry-over and solubility in ...

When this steam is expanded through a turbine to 690 kPa (ga) the solubility of SiO 2 decreases to about 0.0205 mg/kg. The silica coming out of solution (0.0746 À 0.0205 = 0.054 mg/kg) could coat turbine blades and eventually result in extensive turbine maintenance.
