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.

4. ROLE OF MILLS • Produces Pulverized coal 80% of which passes through 200 mesh • Air mixed with Pulverized coal (PF) is carried to the coal nozzle in the wind box assembly. • PF from coal nozzle is directed towards the center of boiler burning zone • Preheated secondary air enters boiler and surrounds the PF and help in combustion. 5.

Thermalbased power plants can produce electricity from coal or other fuel sources. The coalfired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2. Learn how the process works as well as interesting ...

Thermal efficiency is defined as the ratio of heat equivalent mechanical energy available at the turbine to the heat energy available at the combustion of coal in the boiler. The thermal efficiency of the thermal power plants is 30% approx. Most of the heat energy (approx. 50%) is wasted in the condenser.
