The diagram below illustrates how electricity is produced in five stages totally.
Overall, starting with coal and oxygen are put together. Then, chemical transformations have affect on them so as to produce electricity.
The very first stage begins with automatic transportation of coal to a furnace. Besides, oxygen-another ingredient is added. This combination lead to raw syngas. On the other side, the leftover which is slag is eliminated. Raw syngas undergo the removal in order to put out CO2, Mercury, Sulphur and have purified syngas. Gas turbine is the next station. There are two directions. The first one lead to generator to make electricity. Or hot exhaust gases from gas turbine can come to heat recovery steam generator. It is disposed to make steam. Flue gases are discarded out of generator. Steam has to go through steam turbine and generator before creating electricity.
