| Research Abstract |
Investigation of blast extinguishment of a methane-air diffusion flame by using micro-explosive charges (silver azide pellets) has been performed experimentally. In order to clarify the characteristics of blast extinguishment, the flame height, explosion energy and distance from the explosion point to the flame base were varied as a parameter. As a result, it is found that the flame extinguishing distance from the explosion point, in which the blast extinguishment probability shows always unity, depends on the effective distance of blast wave produced by silver azide explosion, and the value of the flame extinguishing distance divided by explosive energy to the power of one third becomes constant.
