ANSWER (8.0+):
The given picture illustrates how a certain type of coal is used to generate electricity. Overall, there are three main stages in this process. It starts with the extraction of coal, continues with processing this material to generate electricity and culminates with distributing electricity to various locations for household and industrial purposes.
Regarding the material preparation stage, a specific type of coal is mined from coal mines using specialised equipment. It is then ground by crushers and dumped into crates. Finally, the crushed coal is delivered by trucks to thermal power plants.
Concerning the production and delivery stages, the coal received at the plant is first gasified using heat. The gas produced is subsequently pumped into a cooling system where waste heat is released. The following step involves cleaning the gas to remove any impurities before it is utilised to produce electricity in a power plant. At this plant, another volume of waste heat is also released and the electricity is finally distributed to households for domestic use or to industrial areas.
