The diagram illustrates the process by which electricity is produced from coal. Overall, there are several stages in this process, commencing with the exploitation of coal from mines, and culminating in the production of electricity. At the beginning of the process, coals are extracted from mines and subsequently transported to a crusher, where they are crushed into smaller pieces. After which, crushed coal is delivered by trucks to a gasifier, in which they are heated under high temperatures generated by thermal energy to produce gas. The process continues when newly generated gases undergo low temperature in a cooling facility, at which point, unwanted heat is released as a by-product. The gases are then directed to another factory to remove any impurities. Once the purified gases channel into a gas power plant, they are transformed into electricity, leaving additional waste heat. Finally, the electricity is transmitted to either households or industrial areas via power lines.
