The diagram below illustrates how electricity is generated from coal in an energy company. Overall, the process requires a lot of physical and chemical reactions throughout the whole chain. To begin with, the raw charcoal is transported to the large furnace by vans and then people adds oxygen into the furnace to start the burning process. The results including raw syngas is led out and continues to undergo the removal section where toxic substances like CO2 and mercury sulfur are eliminated from the purified syngas. Surprisingly, the factory don't throw the slag away however use it to combine with the clear syngas providing for the round series of generation and recycling energy. The gas turbine connected directly with the generator convert previous products into electricity contributed to the high voltage line system. In another line of the chain, where exhaust gases are recycled by the heat recovery steam generator in other to avoid wasting materials. These gases then continue to be used to manufacture power by steam turbine and generator system.
