摘要
最小点火能是衡量可燃气体(或蒸汽)爆炸危险程度的一个重要参数,对它进行较为准确的测定有重要意义.不同的实验装置和不同的测定方法所测结果有很大差别.本文介绍了气体爆炸最小点火能测试的主要影响因素,通过实验找出了在20L爆炸罐中最小点火能测试的敏感条件,为最小点火能的准确测试提供了必要基础.
Minimumignition energy(Emin)is one of the important characteristic parameters of conbustible vapor explosion.It expresses the sensitivity or dangerous extent of combustible vapor.However,in different experimental conditions,dif- ferent experimental resuIts of Emin will be obtained.Therefore,determining the optimum experimental conditions will be necessary.In this paper,the main influ- ence factors of Emin are discussed;the optimum test conditions of Emin in 20 L test vessel are experimentally obtained,which offers a reliable base to test Emin accu-rately.
