The picture illustrates how fossil fuel (coal) is used for producing electricity.

Overall, there are nine main stages of the process, beginning with the provision of coal and ending with the disposal of ash.

First, the supply system delivers coal to a pulverizer whose purpose is to crush coal into granules. The pulverized coal then goes to a boiler, the coal is burned which heats water to generate steam. Beside the boiler is a dust collection system which eliminates all the coal dust in the fumes before emitting it to the air. At the fifth stage, the steam goes to a pipe leading to a turbine. The steam spins the turbine which is connected to a generator, as a result, the generator is activated to generate electricity in the substation/transformer. The ashes from the burning coal in the boiler are collected and transfer to the disposal. After the steam goes through a turbine, it is passed to a condenser to return to the liquid form. Once the steam is transform to the water, then it goes back to the boiler and the process starts again.
