In most of the thermal power plants, coal is used as fuel. During the combustion of coal, the flue gases are generated in the boiler. The chimney provides a path to the flue gas and exhaust to the atmosphere. The chimney works based on the natural draft and stack effect. The hot air is light in weight and it goes up.

How a Coal Plant Works. Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.
