Experimental research on minimum ignition energy of Lycopodium/Coal/Ultrafine powder mixed system

Abstract

In this paper, the dust cloud minimum ignition energy experimental instrument is used to study MIE of the mixed system dust of mix lycopodium powder, coal powder and ultrafine powder. The experimental results show that: (1) MIE of the three mixed systems decreases with the decrease of dust particle size under the working condition of 20h dust drying and 60ms ignition delay; (2) MIE of the dust of the three mixed systems decreases with the increase of the dust drying degree under the working condition of 300 meshes and 60ms ignition delay below;
