The diagram shows the process involved in the production of energy from coal.
First of all, the coal is delivered by lorry. After that, it is carried along a conveyor belt to the power plant, where it is burned in a large furnace to which oxygen is added. From
this
, raw syngas is produced. At the next stage of the process, harmful substances like carbon dioxide, mercury and sulfur are removed. Following that, purified gas is used to drive a gas turbine
. The turbine
in turn powers a generator, producing electricity. The gas turbine
also
produces hot exhaust gases. These are then
piped to a heat recovery steam
generator, which converts the heat into steam
. The steam
is subsequently
used to power a steam
turbine
, which again is used to generate electricity.
It is clear that
the production of energy from coal requires a series of stages, including the use of exhaust gases.Submitted by s_syedy on
