Boiler design for ultra-supercritical coal power plan

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).

What is Supercritical Steam? | Technology-Articles.c

Nov 12, 2017· So, supercritical steam is water at a temperature and pressure above its critical point (>647.096 K, >22.064 MPa), where distinct liquid water and steam phases do not exist. It can effuse through solids like a gas, and dissolve materials like a liquid.

Yuhuan 1,000MW Ultra-Supercritical Pressure Boile

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%. Siemens reports that just a 1% gain in efficiency for a typical 700MW plant reduces 30-year lifetime emissions by 2,000t NOx, 2,000t SO 2 , 500t particulates and 2.5 million
