Apparatus for determining the oxidation of coal according to Ukrainian State Standard DSTU 7611:2014 is used to determine the influence of the heating rate and degree of oxidation of coal on its ignition temperature. By means of the Kissinger equation, the activation energy, preexponential factor, and rate constant of ignition are calculated for coal samples of different metamorphic development and degree of oxidation. The rate constant of ignition increases with increase in the degree of oxidation and decrease in the metamorphic development of the coal. Oxidation increases not only the rate constant but also the activation energy of coal ignition.
