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 given diagram demonstrates the process of electricity production. Looking from an overall perspective, it is immediately apparent that electricity was acquired by 2 various ways, both of which comes from gas power which was created combination of coal and oxygen heating.
In the first step, coal and oxygen are transferred into specific furnace where the combination is heated. Then heated mixture sorted into slag and raw syngas. Raw gas is sent for removal where CO2,Mercury and Sulphur are throwed away. After that with the power of purified syngas, generator is ran which is the first way of getting electricity.
When it comes to second way, hot exhaust gases from gas turbine is transferred to steam generator where flue gases are released into atmosphere. The generator produces steam which turns the turbines of a steam turbine to generate additional electricity.
