Jan 06, 2020· The process in the case of a coal-fired generating station begins when the coal is brought into the station on a conveyor belt after stored in large coal piles just outside the station. The conveyor feeds the coal into large pulverizers that crush the coal into a fine powder, thereby increasing the surface area and allowing it to burn more quickly.

Getting Energy from Resources | Geology

For a fuel to be useful, its energy must be released in a way that can be controlled. Controlling the release of energy makes it possible for the energy to be used to do work. When fuel is used for its energy, it is usually burned, and most of the energy is released as heat (figure 2). The heat may then be used to do work.

The raw coal is then fed into the pulverizer along with air heated to about 330°C (650°F) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.

How a Coal Plant Works - TVA.com

Sep 18, 2021· 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.
