The diagram illustrates the way that electricity is produced from coal.
Overall, there are several sophisticated stages in the production of electricity from coal, from the collection of coal from mine to the distribution of electricity to buildings.
At the first stage of the the electricity-generating process, coal is extracted from a mine, then it is crushed into small pieces. After that, these small coal pieces are transported by trucks to a gasifier, where heat is used to converts solid coal into gas.
Subsequently, the gas is cooled and cleaned before being sent to gas power plant. Finally, generated electricity is supplied to houses and industries, while waste heat is disposed.
