Electrostatic Discharge and the Minimum Ignition Energy Measurement of Three-Component Flammable Gas Mixtures

정전기(靜電氣) 방전(放電)과 삼성분계(三成分系) 가연성(可燃性) 혼합기체(混合氣體)의 최소점화(最小點火) Energy 측정(測定)에 관한 연구(硏究)

When flammable gases are mixed with air or oxygen in the explosion concentration range and are ignited by sufficiently large electrostatic discharge energy, they may explode causing severe disaster in workplaces. The minimum ignition energy (MIE) of single gas-air mixtures has been already investigated by many researchers, but the MIE of mixtures of more than three substances is not examined yet. The purpose of this study is to investigate the MIE of several three-component gas mixtures experimentally. The result of our experiment shows that the MIE of some gas mixtures is quite different from that we expected based on the characteristics of individual gas-air mixture.
