The combustion charac- e b m teristics and kinetics of Lingwu coal and corresponding macerals were researched by e c e means of the thermogravimetric analysis method. The results showed that inertinite D 7 has slightly higher combustion activity than that of raw coal and vitrinite, but it is also 1 0 responsible for last carbon loss. As inertinite content increases,the combustion activity 4 : of the blending sample increases slightly, whereas the last carbon conversion reduces. 3 0 : The shrinking core model is used to illustrate the sample combustion mechanism.
