The diagram delineates the procedural mechanisms involved in the conversion of coal into electricity, encompassing multiple stages from coal extraction to the eventual distribution of electricity.
Overall, the process is characterized by a series of transformations where coal undergoes fragmentation, gasification, cooling, cleaning, and ultimately conversion into electrical energy, with notable heat waste at various stages.
Initially, the process commences with the extraction of coal, which is subsequently fed into a crusher to facilitate its fragmentation. Following this, the crushed coal is transferred to a gasifier, where it undergoes a conversion to produce gaseous fuel along with significant heat generation. This heat is subsequently released into the environment, indicating inefficiency in energy retention. The resultant gas then undergoes a cooling phase in designated cooling systems, where additional waste heat is emitted, further contributing to energy loss.
Upon cooling, the gas is directed to a cleansing unit where it is refined and purified to remove impurities. Once purified, the gas is supplied to a gas power plant, where it is converted into electricity. This stage also generates substantial heat byproducts, which remain unutilized, thereby emphasizing the inherent inefficiencies in the entire coal-to-electricity conversion process. Finally, the produced electricity is distributed to various consumers, including factories and power plants, which then allocate it to schools, residences, and other essential facilities.
