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 process illustrates the stages by which clean energy is harnessed from coal.
From an overall perspective, it is evident that this process is mainly done using machinery. In addition, it encompasses several stages, starting with mining coal from deep underground and culminating in generating electricity.
Looking at the details, the initial stage takes place outside the plant where coal is extracted from the ground and carried to a large furnace, where oxygen is added to dug coal through a tube, with the help of a conveyor to be burned. Once burned, slag is removed from raw syngas, followed by another purification step from harmful substances like carbon dioxide, mercury and sulphur. In the subsequent stage, purified syngas is driven to a gas turbine powering a generator to produce energy. The gas turbine also produces hot exhaust gases which are piped to a heat recovery steam generator, converting the heat into steam. As soon the steam is used to power a steam turbine, the process culminates when electricity is harnessed.
