The picture illustrates how to produce electricity from one type of coal.
Looking from an overall perspective, it is readily clear that the process comprises a number of steps, beginning with the mining coal and ending with the supplying electricity to houses and industries.
At the beginning of the process, the coal is collected from a mine, after which they are crushed into smaller pieces and then transporting them to the gassifier. In there, a part of coal is cleaned, while the rest of it in solid will be thrown away.
The process continues with the cleaning coal is cooled by adding gas in lower temperature. Next stage is that the production is moved to the gas power plant in order to create the electricity and some of the heat is released. At the final stage of the process, electricity is produced to be distribute for houses or the factories
