Blast extinguishment of a methane-air jet diffusion flame using a silver azide pellet
Ryo Sekikawa and Hiroyuki Torikai
p.12-14

Abstract

To elucidate the effect of an explosion location on the blast extinguishment, extinguishing experiments of a methaneair jet diffusion flame have been performed by using a 10 mg silver azide (AgN3) pellet. We have recorded the extinguishing process with a high-speed camera and measured the extinguishing probability by varying the explosion location. From the results, the optimum explosion height for the blast extinguishment has been clarified.
