Yuhuan 1,000MW 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. This gives a net efficiency of 46%.

Working Principle of Supercritical Steam Generators -

A supercritical boiler 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.

Development of a supercritical and an ultra

The supercritical circulating fluidized bed (CFB) boiler, which combines the advantages of CFB combustion with low cost emission control and supercritical steam cycle with high efficiency of coal energy, is believed to be the future of CFB combustion technology. It is also of greatest importance for low rank coal utilization in China.

Working Principle of Supercritical Steam Generators -

A supercritical boiler 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.
