The combustion kinetics of the imported bituminous coal was studied in the interme-diated heating rate. The activation energy and the frequency factor were obtained by experi-ment of the coal weight loss depending on the combustion time with Ih. furnace. The experi-ments were performed in the heating rates of $1,5,10^{circ}C/sec;or;20^{circ}C/sec;at;the;600-900^{circ}C$ maximum temperature, The values of the activation energy(E) which were calculated from the experimental data existed in the range from 3000cal/g-mol to 15000cal/g-mol, and those of the frequency $factor(1nk_O)$ were in the range from 4.5cm/sec to 11.5cm/sec.
