The illustrations demonstrate how electricity is generated from coal. Overall, the process consists of eight primary steps, commencing with the extraction of coal from the mine, followed by the transformation of coal into electricity, and concluding with the distribution of electricity for both household and industrial use.
The first four steps involve processing the raw coal into gas. Starting with the first step, coal is taken from the mine, piled up, and then placed into a crusher, where it is ground into small pieces. The crushed coal is then transported by trucks to a gasifier, which burns the coal to produce gas before undergoing further processing.
In the subsequent stages of the process, gas is converted into electricity. Specifically, this gas is then cooled in a dedicated facility, releasing excess heat in the process. Following the cooling stage, this gas undergoes a cleaning process before being sent to a gas power plant. At this point, the gas is converted into electricity, which also emits waste heat. Ultimately, the electricity produced by this process is made available for consumption in residential and industrial activities.
