The diagram below shows how energy is produced from coal. Summarize the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.
The graph illustrates the process of producing energy from coal and oxygen.
Overall
, the diagram shows that by combining coal and oxygen in a furnace, we obtain either raw syngas
or slag. Using various machines, these can be converted into electricity.
First,
after coal and oxygen react in the furnace, the output can be directed to a gas turbine, which then
moves to a heat recovery steam generator. This
setup, combined with a steam turbine and a generator, produces electricity.
Alternatively, the furnace can yield raw syngas
. This
syngas
undergoes a removal process to extract mercury and sulfur, resulting in purified syngas
. The purified syngas
can then
be used in the same process as slag to generate electricity.Submitted by khalidashgar23 on
