The diagram illustrates the process of producing electricity from coal using a gasification system.
Overall, coal is converted into gas through a sequence of mechanical and chemical stages, and the generated gas is later used to produce electricity in a power plant. The process consists of several steps, beginning with crushing the coal and ending with the generation of electricity.
Initially, coal is extracted from a mine and transported to a crusher, where it is broken into smaller pieces. The crushed coal is then delivered to a gasifier. At this stage, heat is applied and the coal is transformed into gas. After gasification, the gas undergoes a cooling process and is subsequently moved to the cleaning unit, where impurities are removed.
Once the gas is cleaned, it is transferred to a gas power plant and burned to generate electricity. During this stage, waste heat is produced. Part of this heat is directed back into an earlier stage of the process to support gasification, while the remaining electricity produced is supplied to consumers
