  • Difference Between Subcritical and Supercritical Boiler

    Feb 19, 2018 · Subcritical boilers are boilers that work at temperatures up to 374°C and at a pressure of 3,208 psi (the critical point of water). Supercritical boiler (supercritical steam generator) is a type of boiler that works under supercritical pressure conditions.Learn More


    Based on the operating pressures, there are two basic boiler technologies employed in the modern coal-fired coal power plants. These are Subcritical and Supercritical Subcritical boilers operate below 220 bars, the supercritical pressure of water.Learn More

  • Supercritical Power Plant - Rajmohan - Google Search

    A supercritical power plant uses a boiler/turbine system that operates at 1075 degrees F; subcritical plants operate at 850 degrees F. A supercritical plant is much more efficient than a subcritical plant, producing more power from the less coal and with lower emissions. Benefits of advanced supercritical power plants includeLearn More
