CoalFired Power Plant: Coalbased power plants are a type of power plant that uses coal combustion to generate electricity. Countries like South Africa use coal for 94% of their electricity, and China and India use 7075% of coal for their electricity needs; however, the amount of coal in China dwarfs that in other countries.

Stage 1 The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2 The second stage is the thermodynamic process. The heat from combustion of the coal boils water in the boiler to produce steam.
