Thermal power station Wikipedia

A thermal power station is a power station in which heat energy is converted to electric power most places the turbine is steamdriven.Water is heated, turns into steam and spins 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 it was heated. This is known as a Rankine

Sep 27, 2013 · ASH HANDLING PLANT The percentage of ash in coal is 5% in good quality coal & about 40% in poor quality coal. Power plants generally use poor quality of coal, thus amount of ash produced by it is quite large. A modern 1000MW plant produces about 4800 tons of ash daily. The stations use some conveyor arrangement to carry ash to dump sites.
