The diagram depicts the process of generating energy from coal.
Overall, it is a man-made, linear process that consists of several stages and two vital sources (coal and oxygen). The whole procedure begins with both coal and oxygen being utilized in the furnace and culminates in producing electricity for the national grid.
Initially, the fossil fuel is transported by vehicle and then is heated in the furnace with oxygen. As a result, the slag is released outside through the bottom; meanwhile, the raw syngas is extracted to undergo a specific process to remove harmful carbon dioxide. After separating mercury and sulfur, purified syngas is sent into the gas turbine where it activates a generator, which produces electricity to be sent to the electric tower.
The next stage starts with the gas turbine again, where hot exhaust gases are delivered to the heat recovery steam generator in another direction, which releases flue gases into the atmosphere for cleansing the gas. Once steam is generated by heating in a facility, it moves through the steam turbine to create electrical power in the generator. Finally, the electricity is sent to the central power station for public consumption.
