Thermal Analysis Experiment

To ensure the accuracy and stability of results of coal oxidation and spontaneous combustion in the process of thermal analysis experiment, the speed and time of coal oxidation must be moderate, and the characteristic parameters in the oxidation process can be fully reflected. Thermal analysis experiment at different heating rates, with several particle sizes and different sample quality, Huangling coal sample as the research object, were carried out in this paper. Results showed that the particle size of 0.075 mm to 0.109 mm, sample quality of 5 mg and the heating rate of 10 K•min-1could ensure the fully oxidation and pyrolysis of coal, under which conditions coal spontaneous combustion characteristics could be reflected by the characteristic temperatures.
