Abstract

In order to study the effect of different initial conditions on gas explosive limits, the gas explosive limits have been measured under different initial temperatures(50~200℃)coupled with different ignition energies(50~800J). Besides, it has been obtained that the change rules of the upper and lower limits of gas explosion under the effect of initial temperature, ignition energy and the coupling conditions of the both. The experimental results show that the coupling condition of initial temperature and ignition energy has a great influence on the gas explosive limits. With the increase of initial temperature and ignition energy, the upper limit of gas explosion increases while the lower explosive limit decreases, and both its rising and falling trends tend to be gentle. In addition, according to the analysis on two-factor multi-level variance analysis, it can be seen that both ignition energy and initial temperature have a significant effect on the upper and lower limits of gas explosion under the coupling conditions.
