摘要
本文通过对煤气管道内沉积物的化学和物理分析,并根据铁的硫化物的物化特性,认定煤气管道中的自燃物质是铁的硫化物。在此基础上,对本公司近年来在煤气管道施工和维修作业中发生的几起着火事故的原因再次进行了分析,提出了自燃着火的预访措施。
Through chemical and physical analysis of the deposition in gas pipes, and according to physicochemical character of ferro-sulphide, itis considered that ferro-usulphide is identified as spontaneous combustion substances in gas pipes.on the basis of that the reason of some fire accidents which happened under gas pipe construction and maimtenance are analyzed, some measures to prevent spontaneous combustion are discussed.
