摘要
Maceral composition and mean reflectance are considered to be important parameters influencing the coal combustion characteristics. The combustion characteristics and kinetics of Lingwu coal and corresponding macerals were researched by means of the thermogravimetric analysis method. The results showed that inertinite has slightly higher combustion activity than that of raw coal and vitrinite, but it is also responsible for last carbon loss. As inertinite content increases, the combustion activity of the blending sample increases slightly, whereas the last carbon conversion reduces. The shrinking core model is used to illustrate the sample combustion mechanism. With increasing heating rate, the activation energies and pre-exponent factors decrease on sample combustion.
