  • High Pressure Boiler: What is it? Types & Characteristics

    The division of megapascal pressure (MPa) determines whether a boiler is low and high pressure. Boilers that produce pressure above 80 MPa are considered to be high pressure. Low pressure boilers have a MPa below 80 MPa. Water circulation can be forced or natural. If the water is pumped, it is forced.Learn More

  • Boiler Efficiency and Combustion | Spirax Sarco

    A reasonably well-insulated shell or water-tube boiler of 5 MW or more will lose between 0.3 and 0.5% of its energy to the surroundings. This may not appear to be a large amount, but it must be remembered that this is 0.3 to 0.5% of the boiler's full-load rating, and this loss will remain constant, even if the boiler is not exporting steam to Learn More

  • Steam Boiler Flooding & Surging Causes & Repairs

    Apr 23, 2017 · Clean the boiler and adjust its pH if needed. Too-high pH in boiler water (water that is alkaline or "basic") causes frothing and surging. pH in a steam boiler should be between pH 7 and pH 9. A leak in a tankless coil used to make domestic hot water (not found on all steam boilers) will leak higher pressure (building water supply pressure 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
