In this paper air was passed through into one progress temperature-controlled box with coal sample and nitrogen into another as comparison during the procedure of coal’s low-temperature （10～80°C）oxidation . Draw the heating curves and heating rate curve, and equation model is built combined with energy conservation, then concludes the heat release rate of the coal samples in the air conditions. The experimental results show that the condition with air is more close to the storage conditions of coal such as transportation in reality, which is very significant to prevent the spontaneous combustion of coals
