The diagram below shows how one type of coal is used to produce electricity. Summarise the information by selectting and reporting the main features, and make comparisions where relevant.
The graph illustrates how electricity is produced from coal.
Overall
, it requires lots of stages and heat
waste. First,
it has to be heated, then
cooled and again heated.
The process starts from a mine that crushes coal. Further
, the smaller pieces of the product are transported to the gasifier. Thanks to heat
, minerals are transformed into gas. However
, it is not the end of the production. Because of pollution, it has to go through additional steps. If the product is not clean, it will not be possible to use.
In the second stage, gas has to be prepared to meet quality requirements. Firstly
, it goes through the process of colling. Consequently
, some heat
is wasted. Secondly
, it has to be cleaned. After reaching the gas power plant and wasting some more heat
the final product travels to individuals and institutions. From this
moment consumers can use electricity.Submitted by Aga
