Abstract

Flammability limits of isobutane and five kinds of binary mixtures of isobutane were measured by the ASHRAE method. Propane, nitrogen, carbon dioxide, chloroform, and HFC-125 (1,1,1,2,2-pentafluoroethane) were used as the counter part gases in the mixtures. The observed data were analyzed using the equations based on Le Chatelier's formula. The flammability limits of mixtures with propane were well explained by the original Le Chatelier's formula. The flammability limits of mixtures with nitrogen and the ones with carbon dioxide were adequately analyzed by the extended Le Chatelier's formula. It was found that the extended Le Chatelier's formula is also applicable to the flammability limits of mixtures with chloroform and HFC-125.

摘要

采用美国供暖、制冷与空调工程师协会（ASHRAE）的方法，测定了异丁烷以及五种异丁烷二元混合物的可燃极限。丙烷、氮气、二氧化碳、氯仿和HFC - 125（1,1,1,2,2 - 五氟乙烷）被用作混合物中的对应气体。使用基于勒夏特列公式的方程对观测数据进行了分析。含丙烷混合物的可燃极限可以用原始的勒夏特列公式很好地解释。含氮气混合物和含二氧化碳混合物的可燃极限通过扩展的勒夏特列公式得到了充分分析。研究发现，扩展的勒夏特列公式也适用于含氯仿和HFC - 125混合物的可燃极限。
