Silica Monitoring TECHNICAL NOTE On Power Plant
19/12/2009 · For pressure range 166-205 silica in boiler water to be kept below 0.10 ppm. The phosphate and pH are given based on Co-ordinate phosphate treatment so as to prevent the presence of free hydroxide in the boiler water. Normally each power station has their own practice; the values given are only a guideline as understood from various practices.
Silica is the only boiler watersalt which vaporizes at pressures below 2400 psig. It can vaporize at pressures as low as 400 psig. This has caused deposition problems in numerous turbines. The solubility of silica in steam increases with increased temperature: silica becomes more soluble as steam is
This limit is generally 0.100 ppm or less. Even where steam purity requirements are not imposed by the application, dissolved solids concentrations less than 1.0 ppm are recommended at pressures up to 600 psig (4.1 MPa), less than 0.5 ppm at 600 to 1000 psig (4.1 to
