How To Convert Coal Into Electricity?

Electricity from coal is generated when coal is burned. Thus heat energy is converted to electricity. Now there are various processes by which coal energy is converted to electricity.

Firstly a machine called "pulverizer" grinds the coal into fragments and powder. Then by mixing it with hot air the coal burns efficiently. Then it is moved to a furnace. Spinning turbines transforms the heat energy produced by the coal into mechanical energy. This energy is used to power a generator. In the generator there is a copper coil in the generator spin which converts the mechanical energy into electricity. Thus coal is converted into electricity.

With improvement in science and technology many new researches are taking place to use coal more efficiently.
