Our system will evaluate the answer based on this AI-generated description.
The image is a flow diagram illustrating the process of coal gasification and electricity generation. It starts with coal being input into a furnace, where it reacts with oxygen to create raw syngas. Flue gases are generated as a byproduct and sent through a heat recovery steam generator to create steam, which powers a steam turbine connected to a generator to produce electricity. The raw syngas goes through a removal process to eliminate CO2, Mercury, and Sulphur, resulting in purified syngas. The syngas then powers a gas turbine connected to another generator to produce additional electricity. Byproducts of the process include slag and hot exhaust gases which are depicted as leaving the system. No numerical data points or percentages are provided.
Given the complexity of the image, the above description may not be entirely accurate.

The image gives information about how coal can be transformed to electricity by several steps.
Overall, most of the work is done by Furnace what makes an important substances and generators generate electricity by those substances.
First of all coal is put into huge container shaped furnace. Inside the container fire is held and coal is burnt. To strengthen the fire oxygen also enters to container by special tubes. After that the slag of it is thrown away and the raw syngas comes out reaction. To purify the syngas, carbon dioxide, mercury and Sulphur are removed from raw syngas so it becomes purified.
The pure syngas will go to gas turbine which sends them to generator to make electricity and hot exhausted gases will be sent to destined generator what makes steam from those gases. It is called heat recovery steam generator, emits flue gases as well. Then steams comes to steam turbine which helps to generator to make electricity.
