The diagram delineates the method of electricity generation from a specific type of coal, illustrating each stage of the process.
Overall, the procedure involves multiple stages, starting from coal extraction and culminating in electricity production, with various intermediary processes that enhance efficiency.
Initially, coal is extracted from a mine and subsequently transported to a crusher, where it is subjected to mechanical breakdown. Following this, the crushed coal undergoes cooling and cleaning processes, during which gas and waste heat are produced as byproducts. This enhanced coal is then moved to a gasifier, where it is further processed to yield additional gas and heat. These preliminary stages are critical as they not only prepare the coal for more efficient energy conversion but also generate byproducts that may be utilized in later stages.
In the penultimate phase, the treated gas is directed towards a gas power plant, where it is employed in the generation of electricity. Additionally, the waste heat from both the cooling/cleaning stages and the gasifier is harnessed and integrated into the electricity production process. This dual-purpose usage of waste heat signifies an efficient approach, maximizing the output from the original coal while minimizing energy loss, thereby optimizing the overall electricity generation cycle.
