Effects of Explosion Pipe Structure on the Flame Propagation Velocity and the Quenching Ability of Ceramic Honeycomb Monolity

화염전파속도에 대한 폭발관 구조의 영향과 세라믹 소염소자의 소염성능

The behaviors of flame propagation and quenching in a pipe were investigated to make a design criteria of flame arrester. The effects of sealing condition of pipe end, pipe diameter and lengh were studied, and also the effects of thickness of ceramic honycomb monolith on the quenching ability were discussed. Experimental results showed that the flame velocity in case of closed pipe was increased about twenty times faster than that of opened and the sealing coditions of pipe end and length showed significant effects on it. The quenching ability of ceramic honycomb monolith was Increased with thickness and coincided well with Palmer's equation.
