狭长受限空间火灾临界可燃距离实验研究

油料洞库的安全一直是各级主管部门非常关心的问题。狭长受限空间是地下建筑及地下油料洞库的关键结构,针对狭长受限空间发生火灾能否持续燃烧问题,在公称直径分别为50mm、100mm、150mm和250mm的模拟狭长受限空间上,以柴油作为燃烧工质,置于尺寸、形状各异的3种油盘中,进行了系统实验研究与分析,证实了狭长受限空间临界可燃距离的存在,并在此基础上,提出了计算方法,得出一些有益的结论,对研究油料洞库消防新技术有一定的价值。

Experiment Study and Calculation of the Critical and Combustible Distance in A Long Narrow Confined Space

The safety of underground petroleum storage depot is a problem that all levels supervisor section takes to heart since then. The long narrow confined space is a key construction of underground building and underground petroleum storage depot. In diameter distinguishing to 50mm, 100mm, 150 with 250mm of the long narrow confined space, the medium of burn is diesel oil in different five oils dish in size and shape. Aiming at the fire can keep on the burnable problem in the long narrow confined space, the paper proceeded the system experiment the research and analyze and substantiate that the critical and combustible distance is exist. Base on it, the calculation method of the critical and combustible distance have been putted forward and some beneficial conclusion have been got that have certainly value to studying oil anticipating new technique in fire fight in underground petroleum storage depot.
