Five coal char samples were burnt in thermobalance with ramp heating rate of 30 K/min.The pore structure of these char samples was studied through mercury intrusion method.Combined with the kinetic theory of gases, the data of surface area was used in fitting the results.As a result, the kinetic triplet was given. The analysis showed that five char samples share almost the same intrinsic activation energy of the overall reaction. The phenomenological implication of the derived combustion rate equation was given.
