    Jun 21, 2016 · In ultra-supercritical steam (USC) power plants, the extreme boiler temperature and pressure heat the water so that it becomes a 'supercritical' fluid that exhibits properties of liquid and gas phases. In this state, supercritical steam is much more efficient at driving the giant turbines that spin the plant's generators.

  • Super critical boiler - SlideShare

    Aug 21, 2014 · Super critical boiler 1. SUPERCRITICAL BOILER SHIVAJI CHOUDHURY 2. What is SUPER CRITICAL The term "supercritical" refers to main steam operating conditions, being above the critical pressure of water (221. bar). Above the critical pressure there is no distinction between steam and water, i.e. above 221. bar, water is a fluid.

    Ultra-supercritical pressure boilers. Supercritical operation of large thermal baseload power plants during the 1980s used steam temperatures of typically 550ºC, leading to around 40% thermal efficiencies. Ultra-supercritical steam conditions now use supercritical pressures up to 300bar, with 600°C steam and reheat steam temperatures.

  • Supercritical coal plant - Energy Education

    Supercritical coal plants are a type of coal-fired power plant used in more modern designs. They differ from traditional coal power plants because the water running through it works as a supercritical fluid, meaning it is neither a liquid or a gas.This occurs when water reaches its critical point under high pressures and temperatures, specifically at 22 MPa and 374 o C.

  • Supercritical steam generator - Wikipedia

    A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power. In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator operates at pressures above the critical pressure – 3,200 psi or 22 MPa.
