Coal gasification is a proven method to efficiently and cleanly use coal. By converting coal into a high-pressure gas called syngas, power plants can generate electricity more efficiently and with fewer environmental impacts. The process involves combining gas and steam turbine cycles for greater power production. Different types of coal can be used, and the chemistry behind coal gasification is explained to improve the process. The study showcases how coal gasification can lead to higher performance and better efficiency in power generation, making it a more attractive option than traditional coal combustion methods. Moreover, the syngas produced can also be used to make chemicals, expanding the potential applications of coal.
