The diagram illustrates how electricity is produced from a particular type of coal.
Overall, the process comprises a number of stages, beginning with the extraction of coal and ending with electricity being distributed to households and industrial sectors.
At the first step of the process, coal is collected from coal mine. Subsequently, the coal is crushed into smaller chunks in order to be transported by a truck to a gassifer. As can be seen for the gassifer stage, the crushed coal is heated and converted into gas.
In the next stage, after being cooled, the gas is moved to a gas power plant, where it is used to generate electricity. Finally, the electriciry is distributed to residential and industrial areas, with waste heat being removed.
