The diagram illustrates the process of generating electricity from coal.
As can be inferred from the picture, the electricity production process involves eight steps, commencing with mining coals and culminating with supplying electric power for household and industrial use.
The process begins with coal being extracted from the ground with the assistance of mining plants. After that, large chunks of coal are crushed into finer pieces before being transported to a gasifier. In which, coal is burned with high heat to create gas. This amount of gas is, subsequently, sent to a separate facility to be cooled off, at the same time, waste heat is released.
In the next steps, cool gas is cleaned and then becomes the input for a gas power plant. While electricity is generated in the power plant, excessive heat is released as a source of waste. Finally, the electric current is sent through the power lines to businesses and homes.
