Our system will evaluate the answer based on this AI-generated description.
The image is a diagram illustrating the process of how energy is produced from coal. The process starts with coal being transported by a truck, then goes to the furnace where it is mixed with oxygen. Flue gases and hot exhaust gases are produced, which lead to a heat recovery steam generator. Steam is created and goes to a steam turbine that powers a generator to produce electricity. In the purification phase, raw syngas is produced, which undergoes removal of CO2, mercury, and sulfur to create purified syngas. Slag is a byproduct of this process. Gas turbine is also part of the process to generate electricity.
Given the complexity of the image, the above description may not be entirely accurate.

The process illustrates different stages in producing energy from coal
It is clear that the process has 2 ways to create electricity, which are made from the purified syngas or hot exhaust gases.
At the first stage in producing energy form coal, after mining in deep pits underground to collect coals and combining to oxygen from factory, it is burned in large furnace. After being burned it, the raw syngas turned up, which get rid of harmful substances such as carbon dioxide, mercury, sulphur. Additionally, the purified syngas is taken from removal process, which is used to drive a gas turbine. The gas turbine passed through the generator, which producing electricity. Meanwhile, the other gas is hot exhaust gases, which are also eliminated by the gas turbine. These gases are heated recovery steam generator, which converts the heat into steam. After that the steam is used to power steam turbine, which keep up with producing the electricity.
