The diagram provided illustrates the process of generating electricity from a particular kind of coal.
Overall, this is a non-natural process which comprises multiple steps occurring at different facilities: starting from mining of the coal, to the production of gas, and eventually the generation of electricity used for various purposes.
Initially/in the first stage, coal is dug/extracted from a mine, after which it is crushed/ground down by a crusher. The ground coal/pulverized coal is then put into a mine cart before being loaded onto a truck for transportation. When/Once this material has been transported to the factory, it is heated to produce gas.
The process continues with the gas being sent to a separate factory/facility , in which it is cooled while waste heat is discharged/expelled. After the cooling is completed/complete, the gas is directed/delivered to a facility where it is cleaned/purified. On the next stage, the gas is again sent/transferred to the plant which uses it to produce electricity and expel/discharge waste heat further. Finally, the generated electricity is dealt/distributed via transmission lines/power lines to homes as well as industries.
