Yuhuan 1,000MW Ultra-Supercritical Pressure Boilers

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

Ultra Supercritical Steam Generation - New Energy …

Pressure in a steam boiler is said to be “supercritical” when the pressure exceeds 3208 psi. A conventional supercritical unit operates at a steam pressure of 3500 psi or higher and steam temperatures of 1000 –1050F. By contrast, a subcritical unit operates below the critical pressure, typically 2400 psi at similar temperatures.
