Abstract

Abstract

In this study we investigated the effect of inert gas addition on the characteristics of the syngas explosion using 20 L spherical explosive device. Effects of different volume fraction of inert gas (CO₂/N₂) on the explosion parameters including the peak pressure, the delay of the peak pressure time, and the explosion index were obtained from the experiment. The results show that the delay of the peak pressure time of the syngas explosion rose higher, and the explosion peak pressure and the explosion index fell lower with the increase of the volume fraction of the inert gas; that CO₂ had a stronger inhibition effect on syngas explosion than N₂ because the peak pressure and the explosion index fell down more sharply with the addition of CO₂ than of N₂.
