The diagram displays the process involved in the production of electricity from coal. Overall, it is a nine step procedure that starts with the suppying of coal to the disposal of ash.
As presented, the process starts when coal is supplied by the coal supply system into the pulverlizer. From there, it will move to the boiler where it is heated. The heat will produce steam that will be passed into a dust collection system that is located inside the stack. From the dust collecting system, the steam will further move into the turbine. A certain amount of the steam will flow into the generator which will in-turn produce electricity and pass it into a substation/transformer.
Furthermore, the remaining steam which does not move into the generator will flow downward, which will also divide and travel in two seperate directions. One part of it will flow into the condenser which will turn the steam into liquid, while the other part will travel into the cooling system. A part of it will escape fromthe cooling systemand travels backwards into the boiler. This steam will gradually act as a cooling tool for the boiler. During the cooling process, ashes will be formed, and the ashes will escape and move downward into the ash system that will eventually dispose it off.
