Detonation Hazards of Gaseous Mixtures

  • Chapter
Prevention of Hazardous Fires and Explosions

Part of the book series: NATO Science Series ((ASDT,volume 26))

Abstract

The critical initiation energy E. for detonation wave (DW) is used as the basic parameter in estimate of detonation hazards. At experimental defmition of Å. the blast explosion approximation is proposed to use. The similar technique is identically suitable both to the various initiators with of large distinctions in the spatial - temporary energy-release characteristics (flame igniters, electrical or laser spark, exploding wire, explosive, high-speed bullet…), and to various mixtures. The priority at theoretical Å. defmition is given up to «multi-point» initiation model based on DW transverse waves collisions as the micro-initiators of a detonation («hot» points). For various fuel-oxygen and fuel-air mixtures the dependence of critical initiation energy Å. on percentage of fuel in a mixture is determined, that allows to find out comparative detonation hazards of various combustible systems at plane, cylindrical and spherical initiation.
