Band 9: The diagram below shows how one type of coal is used to produce electricity.

Image for topic: The diagram below shows how one type of coal is used to produce electricity.
Our system will evaluate the answer based on this AI-generated description.
The image depicts the process of making electricity from coal, starting with a mine where coal is extracted, followed by a crusher that breaks the coal into smaller pieces, then transportation of coal to a gasifier. The gasifier converts coal into gas, which goes through a cooler before reaching the gas power plant. The gas power plant generates electricity that is distributed to houses and industries, while also producing heat waste. Solid waste is shown as a byproduct of the cooler.
Given the complexity of the image, the above description may not be entirely accurate.

The flowchart illustrates how electricity is generated from one type of coal.

Overall, the production is a several-step process. It begins with coal as a raw material and ends with the generated electricity.

Firstly, the coal is extracted from mines and subsequently crushed into smaller pieces. These pieces are then put into a large coal cart and delivered to the gasifier where it is heated and turned into gas. The gas is then transferred to the cooling unit, where it is cooled down to reduce its temperature and separated from waste heat.

Afterwards, the cool gas is subjected to a cleaning process in order to remove any remaining impurities and harmful substances that could affect efficiency. Then, purified gas is transferred to a gas power plant, where it is separated into waste heat and electricity. Finally, the produced electricity is supplied to households and industries. It can then be used for various daily and industrial purposes
