So coalfired power plants haven't changed much since 1882, when Thomas Edison's company built the first one in London. Most still burn coal to boil water. The steam drives a turbine to generate electricity. At the turbine's back end, cooling towers condense the steam into water, lest the highpressure steam there drive the turbine in reverse.

The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a predetermined size in order to increase the surface area of the coal. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.
