摘要
煤自燃主要是由于煤表面活性结构与氧之间相互作用的结果 .通过对煤、氧分子结构特性的分析 ,并根据类似有机结构与氧发生化学反应的条件及过程分析 ,探讨了煤分子表面易于氧化自燃的活性结构 ,归纳出 7种在常温常压下就能与氧发生化学反应的煤分子表面活性基团及其氧化反应热 ,利用煤自然发火实验对推断出的活性基团氧化反应热进行了验证 .在威斯化学结构模型和本田化学结构模型的基础上 ,提出了能够对煤自燃进行描述的煤分子结构模型 ,对煤自然发火机理及其过程的研究具有一定的参考价值 .
The main reason of coal spontaneous combustion is interaction between surface activity structure of coal and oxygen.Through analyzing molecular structure of coal and oxygen,and according to the condition and process of similar organic structure reaction with oxygen,discuss activity structure of easy oxidation and spontaneous combustion in coal molecule surface.The seven surface activity structure and their oxidation reaction heat are induced;they can react with oxygen at normal pressure and temperature.The oxidation reaction heat is tested and verified by experiment of coal spontaneous combustion,and molecular structure model of describing coal spontaneous combustion is put forward.The model is beneficial to researching on mechanism and process of coal spontaneous combustion.
