supercritical power plant layout
Jun 21, 2016· The situation had barely improved three years later when an IEA study into coal-fired power plant design in China found that the global average efficiency of coal-fired power plants in operation was around 33%, significantly lower than the 45% possible using modern, ultra-supercritical technology. Progress is undoubtedly being made, however.
More DetailsSupercritical 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.
