The diagram details the process of generating electricity from coal. Overall, the process consists of four main stages: coal preparation, gas production, electricity generation, and distribution. It is also clear that this process is entirely mechanical, relying solely on machinery and equipment at every step, with no indication of manual labor being involved.
The first stage commences with extracting coal from mines, after which it is crushed into smaller fragments using a specialized machine. The truck then transports this crushed coal to a gasifier, where it undergoes gasification.
In the second phase, the coal is subjected to high temperatures, resulting in the production of synthetic gas. This gas is then transported to a cooling plant, where it is cooled down and waste heat is discharged.
Following this, the synthetic gas is cleaned to remove impurities. Once purified, it is sent to a gas power plant. At this plant, it is combusted to generate electricity. During combustion, waste heat is produced and discharged again.
Finally, the generated electricity is transmitted through power lines to homes and the electricity grid, ensuring a steady supply of power.
