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 provided diagram details methods of producing electricity from coal. Overall, it can be clearly seen that the process of electricity experiences various stages, beginning with burning coal with extra oxygen and ending with generating electricity.
In the first step, the furnace will burn coal that is poured into it with oxygen supplement at the appropriate temperature, which produces raw syngas, hot sap gases, and wasted slag. Following this, raw syngas will be delivered for removal, which helps to separate raw syngas into purified syngas and other gases, namely, CO2, Mercury, and Sulphur.
Subsequently, clear syngas go into the gas turbine and support energy, which assists the generator in generating electricity at the final stage. On the other hand, hot exhaust gases will be transferred to the heat recovery steam alternator. After that, the heat recovery steam generator will supply steam for the steam turbine and deplete flue gases. Finally, the steam turbine supports power to the generator to set up electricity.
