The diagram demonstrates how coal is used to generate electricity.
Overall, in this process, we have 7 stages, which define how we take mined coal and convert it into electricity. There are several stages.
In the beginning, mined coal is taken from pits and then moved into a pulverizer to be crushed properly. Afterwards, it is moved into a furnace to be burned and, when burned correctly, moved into a cooler, producing steam. Now, the steam goes into a turbine, spinning it, and then it moves into a generator. Through the generator, it goes into the transformer, and the transformer process is the main process because the power lines get electricity through the transformer. It means the generator gives power to the transformer, and then electricity moves into power lines, and through the power lines, we get electricity for our homes and industrial areas, etc.
