Depicted in the illustration are the phases involved in the production process of generating electricity.
As can be inferred, the process consists of several steps, commencing with the exploitation of coal from the mine, and culminating in the distribution of electricity to different places for various purposes.
From the beginning, coal is extracted from the mine, after which it is ground into small chunks by a crusher. The pulverized coal is then put into a mine cart before being loaded on a truck for transportation. After being delivered to the factory, it is heated at a high temperature to produce gas.
The process continues with the gas being sent to a separate facility, in which it is cooled while waste heat is discharged. After the cooling process is complete, gas proceeds to be directed to another location where it is thoroughly cleaned. It is thereafter transferred once again to the gas power plant, which uses the gas to produce electricity and expel any excess heat waste. Eventually, the electricity produced is distributed via transmission lines to the residential areas and industries for daily use.
