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 flow diagram below illustrates how electricity is produced.
We can see that the process of electricity production showcases seven stages. For each stage, it requires different raw materials to create electricity.
At the first stage, oxygen which is taken from the factory and coal are added to the furnace. Next, raw syngas which is the mixture after slaged in the furnace will be removed from carbon dioxide, mercury, and sulfur. At the third stage, the purified syngas is taken to the gas turbine to generated electricity at the generator.
Other way is the purified syngas can be transferred to the heat recovery steam generator and will be added the hot exhaust gases. After that, flue gases which is released by the heat recovery steam generator. In the final step, the result steam then will be lead to the steam turbine and the generator so the electricity can be produced.
