Abstract
The effect of the obstacle location L, the distance D, the number N and blockage rate BR on the explosion resistance performance of hydrogen crimped-ribbon flame arrester was investigated. The experimental data including the flame velocity Vf, the explosion pressure Pf and flame temperature Tf entering the flame arrester, and the corresponding flame resistance result Rs were obtained. The results indicated that the Vf, Pf and Tf showed a trend of first increasing and then decreasing with the increase of L, D and BR, while the probability of flame resistance success showed an opposite change trend. The explosion intensity was the highest as L = 650 mm. The Vf, Pf and Tf showed an increase trend with the increase of N, and the rising degree was continuously increased. The hydrogen explosion inhibition by the crimped-ribbon flame arrester was mainly attributed to the combination of endothermic effect and wall effect.
