Differentiation of coking & non-coking coals: From physical appearance it is very difficult if not impossible to differentiate between non-coking & a coking coal. A non – caking coal is that coal which when heated in the absence of air for e.g. as in the determination of VM, leaves a powdery residue. A non-caking coal is always a non-coking coal.
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 ...
