Coal utilization - Coal utilization - Gasification: While the goal of combustion is to produce the maximum amount of heat possible by oxidizing all the combustible material, the goal of gasification is to convert most of the combustible solids into combustible gases such as carbon monoxide, hydrogen, and methane. During gasification, coal initially undergoes devolatilization, and the residual ...
