长期以来国内外学者对煤炭自燃的原因和过程已经作了大量的研究。迄今为止,人们对临界温度(60～85℃)以上的自燃情况基本上有了比较统一的观点,即煤炭自燃是由于氧化放热积蓄的结果。但是对临界温度以下的情况,尤其是煤炭暴露于空气当中后,最初的自燃状态是如何引起的,现在还众说纷纭,分歧较大。本文的研究重点即临界温度以下的煤炭自燃过程。
For a long time, scholars at home and abroad have made a great deal of research on the causes and processes of spontaneous combustion of coal. So far, people have a fairly unified view on the spontaneous combustion above the critical temperature (60-85 ° C), that is, the spontaneous combustion of coal is the result of the exothermic heat of oxidation. However, the situation below the critical temperature, especially after the coal is exposed to the air, the initial state of spontaneous combustion is caused, and now there are still many different opinions and divergences. The focus of this paper is the coal spontaneous combustion process below the critical temperature.
