Supercritical coal plant - Energy Education

Deze pagina vertalen

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.

Thermal power station - Wikipedia

A thermal power station is a power station in which heat energy is converted to electric power.In most, a steam-driven turbine converts heat to mechanical power as an intermediate to electrical power. Water is heated, turns into steam and drives a steam turbine which drives an electrical generator.After it passes through the turbine the steam is condensed in a condenser and recycled to where ...
