Supercritical 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.

What is SUPER CRITICAL The term "supercritical" refers to main steam operating conditions, being above the critical pressure of water (221. bar). Above the critical pressure there is no distinction between steam and water, i.e. above 221. bar, water is a fluid.
