Coal based power plant SlideShare

Jun 16, 2014· A thermal power station is a power plant in which the prime mover is steam driven. Water when heated turns into steam which drives a steam turbine. After passing through the turbine, the steam is condensed in a condenser and recycled to where it was heated. [Rankine cycle] Coal is used as a fuel to heat water in a coal based thermal power plant....

Supercritical coal plant Energy Education

Supercritical coal plants are a type of coalfired 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 occurs when water reaches its critical point under high pressures and temperatures, specifically at 22 MPa and 374 o C....
