程序升温条件下煤耗氧特性的研究

In order to understand the characteristic of coal-oxygen reaction, the oxygen consumption of coal at programmed temperatures were tested with the experimental system of spontaneous combustion of coal. As a whole, the oxygen consumption of coal on the same condition increased with the rise of the temperature of coal but reduced with deepened of the coal rank. However, the oxygen consumption of coal reduced with the rise of the temperature of coal at the beginning. Base the theory of coal-oxygen reaction, the phenomenon above was analyzed in the physical and chemical characteristic, the appearance of coal-oxygen complex and so on. The study indicated that the oxygen consumption of coal at programmed temperatures reflect the characteristic of spontaneous combustion of coal perfectly. It’s a good index for study the tendency of spontaneous combustion of coal.
