Fire Tube Boiler Water Limits For Silica Related Information

  • Introduction to boiler scales - Forbes Marshall

    Silica is found commonly in most of the water supplies and is quite difficult to be removed. Silica can form a thin, glassy scale layer called amorphous silica which can be very hard to be removed. 2. Sludge-Along with the dissolved solids, there are some suspended solids in the boiler feed water.Learn More

  • The Importance of Boiler Water and Steam Chemistry

    For most dissolved solids found in boiler water, it is negligible by comparison to mechanical carryover at pressures less than 2000 psig (13.8 MPa). An exception is silica for which vaporous carryover can be substantial at lower pressures. Vaporous carryover depends on pressure and on boiler water chemistry. It is not affected by boiler design.Learn More

  • Boiler Water Quality

    Always use a softener to ensure good Boiler Water Quality. Chemicals are designed to polish away small amounts of hardness that by-passes the softener. Silica in boiler feedwater can be a problem in larger steam boiler systems. You must maintain a Total OH alkalinity ratio of 3:1 in high pressure boilers to prevent plating of silica.Learn More
