Comprehensive Study On The Rule Of Spontaneous Combustion Of Coal In Its Oxidation Process By Thermal Analysis

Thermal analysis technology presented in the paper is a kind of testing method extensively used in different industries. The relationship between weight loss of coal with temperature and time can be measured by TG technology. With the technology coal oxidation process can be understood from the view of chemical reaction and kinetic equation of coal oxidation constructed. The average activation energy E and InA at different stage of oxidation is calculated and the features of the oxidation process are analyzed. The veracity of calculated values of kinetic parameters of coal oxidation is confirmed by graphic method.
