The diagram illustrates the steps involved in producing electricity by using a particular type of coal.
Overall, it can be seen that there are five main stages in the process: crushing the coal, heating the powder to form a gas, cooling the gas, cleaning it, and generating electricity.
Turning to details, in the first stage, a large amount of coal needs to be taken from a mining area in order to be ground in a crusher. Next, the resulted powder is transported to a gasifier by a truck and heated to produce a gas.
Following this, the gas is cooled in a factory by removing unwanted heat before being cleaned. At this point, the purified gas is then sent to a gas power station where it is transformed into electricity by eliminating waste heat. The generated electricity is used in housing for domestic chores and in industrial zones for manufacturing products and commercial purposes.
