【摘要】 本文从导致煤体增温条件和致发起火燃烧两个方面探讨了煤炭自燃的机制,指出了煤分子中侧链、桥键等活性基团在氧化反应中产生自由基,引起链式反应,形成生热条件,而具有很大內表面且易产生自由基的丝炭是煤炭自燃的导火索。更多还原

【Abstract】 This paper discusses the coal spontaneous ignition mechanism from both the condition of temperature increased and the ignition caused of coal Pointing out that the active radicals of side-chain and bridge-bond in coal molecule produce free radicals in oxidation, result in chain reaction and form the condition of heat caused, filamenf-coal paducing free mdicals with high specific inner surface is the blasting fuse of the coal spontaneous ignition.更多还原
