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 provided diagram illustrates the

process

of a certain coal as a raw material for producing

electricity

.

Overall

, there are eight steps which have to be done before the

electricity

can be used by houses or industries.

To begin

with, the

process

starts with mining the coal, and

then

it is crushed into small particles by a crusher. After the coal is crushed, it

then

will be collected in one place.

next,

it will be carried by using a lorry to the trucks.

After

this

point, the

process

are becoming more into changing the form of the coal, the coal from the truck is

then

brought to a gasifier to separate the

gas

and solid waste. After the

gas

evaporates, it next passes the cooling

process

using a cooler to lower the temperature. If the

gas

has been cooled, it is

then

transferred to a

gas

power plant to produce

electricity

, but at

this

stage heat waste is produced.

Finally

, the

electricity

is ready to use for homes or industries.
