The diagram illustrates the process of electricity production from a specific type of coal. Overall, it presents a step-by-step procedure that follows a linear sequence, starting with the extraction and preparation of coal and concluding with the distribution of electricity to consumers.
The process consists of several stages, including crushing, cleaning, gasification, and electricity generation, with waste heat produced at various points along the way.
Initially, coal is extracted from a mine and transported to a crusher, where it is reduced in size. Once crushed, the coal undergoes a cooling and cleaning process. During this stage, residual coal is cleaned while a portion of the gas is collected and sent to a gasifier, accompanied by the release of waste heat.
The cleaned coal is then burned to generate energy at a gas power station, which also produces additional waste heat. Simultaneously, the collected gas is heated in the gasifier and used to power the gas power plant, contributing to increased energy production.
Finally, the electricity generated is distributed to residential and commercial areas.
