| Abstract: | An adiabatic oxidation equipment and the experimental method were introduced. The spontaneous combustion process of three coal samples was studied with adiabatic oxidation using this equipment. It was successful to realize the simulation of spontaneous combustion of coal with 100 g sample and get a temperature curve under ideal adiabatic condition. The mathematic model of adiabatic oxidation was built. According to the model and the test data, the temperature rise rate and generating heat of different temperature sections were obtained. |
