WRITING TASK 1 You should spend about 20 minutes on this task. The diagram below shows how one type of coal is used to produce electricity. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. You should write at least 150 words.

The diagram illustrates the

process

by which coal is used to produce

electricity

. The

process

begins with the extraction of coal, which is

then

crushed into smaller pieces. The crushed coal is transported to a gasifier, where it is converted into

gas

through a heating

process

.

This

gas

then

undergoes a series of steps before it is

finally

used to generate

electricity

. After gasification, the produced

gas

is cooled, during which waste heat is released. The cooled

gas

is

then

cleaned to remove impurities. Following the cleaning

process

, the

gas

is directed to a

gas

power plant, where it is used to produce

electricity

. In

this

stage, additional waste heat is generated as a byproduct. The

electricity

generated is

then

supplied to various facilities. In summary, the diagram demonstrates a multi-step

process

of converting coal into

electricity

, involving crushing, gasification, cooling, cleaning, and the final generation of

electricity

in a

gas

power plant.
