| Abstract: | The paper is concerned with to study of the mechanism of coal self-heating oxidation from normal temperature to ignition temperature by means of thermogravity technique and offers a few kinds of reaction models discussed by the liner correlation calculation. The results suggest that the oxidizing decomposition of coal can be described as a first-order chemistry reaction. Activation energies of kinds of coal are determined in the case. The activation energy of coal is determined in a faster and easier way convenient if the suggested approach is used. |
