Determination of Explosion Characteristics of CH 4 /C 2 H 6 /C 3 H 8 Binary Gaseous Alkane Mixtures
Abstract：In this paper, HY12474B flammable gas explosion limit experimental device was used to study the explosion characteristics of the three kinds of binary gaseous alkane mixtures, which were the mixture of CH 4 , C 2 H 6 and C 3 H 8 with different composition ratio respectively. The experimental results showed that the velocity of flame at both ends of explosion limit of the binary gaseous alkane mixtures relatively slow, and the flame is also not so apparent. The composition ratio of binary gaseous alkane mixture has a greater impact on explosion limit, three kinds of mono alkane can be ranked by their influence as CH 4 ＞C 2 H 6 ＞C 3 H 8 in turn. When the composition ratio of gaseous alkane mixtures decreased, the explosion limit range is reduced, but the maximum explosion pressure peak is increased.
