The diagram delineates the intricate process of energy production from coal, providing a comprehensive overview of the various stages involved.
Overall, the process encompasses coal transportation, combustion, gas purification, and electricity generation, culminating in the production of energy.
Initially, the process commences with the transportation of coal via truck to the furnace, where it is combusted in the presence of oxygen. This combustion yields both slag, a byproduct that is expelled from the furnace, and raw syngas, which comprises various gaseous components. Following combustion, the raw syngas undergoes a purification process that effectively removes harmful elements such as carbon dioxide (CO2), mercury, and sulfur, resulting in the creation of purified syngas.
Subsequently, the purified syngas is directed to a gas turbine, which is integral to the electricity generation system. The gas turbine generates hot exhaust gases that are then processed through a heat recovery steam generator. This generator produces steam, which is subsequently channeled to a steam turbine that drives a generator, ultimately resulting in the generation of electricity. Through this multi-faceted process, energy is efficiently extracted from coal
