    1. Low-pressure heating boilers - (all steam boilers operating at pressures not in excess of 103 kPa (15 psig).) 2. Power boilers are boilers in which steam or other vapour is produced at pressures greater than 15 psig (103 kPa gauge).Learn More

  • Boiler Operations That Affect Efficiency (Part 1)

    In variable pressure operation, boiler pressure is varied to meet turbine requirements. This can significantly improve cycle efficiency when operating at low loads (15 to 40% of maximum continuous rating, or MCR). However, boiler response to turbine requirements is slower in this mode. When fast response is needed, pressure increments are used.Learn More
