Fixed carbon in coal plays a critical role in which aspect?

Fixed carbon is a key component of coal that significantly contributes to its energy generation potential. When coal is burned, it is the fixed carbon that produces the substantial heat necessary for energy production. The higher the fixed carbon content in coal, the more energy can be generated, making it a favorable fuel source for power generation and industrial applications.

In combustion processes, fixed carbon is not responsible for gas release, which is primarily related to volatile matter. Fixed carbon directly influences the efficiency and effectiveness of energy generation, as it provides the bulk of the thermal energy needed. Therefore, focusing on fixed carbon provides insights into the coal's overall quality and suitability as an energy source, highlighting its role in thermal energy conversion.
