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 that

electricity

is generated from one kind of coal.

Overall

, the process contains several complex stages, beginning with coal being exploited, and ending with

electricity

being transacted to residents or factories. In the first stage, these pieces of big coal are exploited from the mine areas; and

then

sent to the specialized machines to crush it into the grinds.

show examples

, the mass coal is transported to the gasifier for heating at high degrees to produce the

gas

. In the subsequent stage, the

gas

is sent to the other factory for cooling, and the high-heat

gas

is emitted outside by chimneys. In the next stage, the hot air is sent to the cleaning treatment through pipes, before generating

electricity

and continuing to be wasted heat in the

gas

power plant.

Finally

, the

electricity

is sold to households and industrial consumers.
