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.

Yuhuan 1,000MW Ultra-Supercritical Pressure Boilers - Power ...

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.
