Abstract

Abstract

In this work we studied the effect of CO₂ on explosion suppression for multi-component mixed gas at different initial temperatures by igniting the gas obtained from adding CO₂ to the mixture of LPG and air. Our study indicates that when the volume fraction of CO₂ reaches 36% at the initial temperature of 15℃, the mixed gas is beyond the explosive range and the critical volume fraction of oxygen is 12.8%; when the volume fraction of CO₂ reaches 39% at the initial temperature of 50℃, the mixed gas is beyond the explosive range, and the critical volume fraction oxygen is 12.2%. The result shows that the effect of CO₂ on the LPG suppression explosion is influenced by temperature to a certain extent.
