A Study of Measurement of Minimum Ignition Energy for Pine Tree Dust on Electrostatic Discharges

정전기 방전시의 소나무목분의 최소착화에너지 측정에 관한 연구

To establish measuring method for minimum ignition energy of explosive powders caused by electrostatic discharge, A measuring method(Hartman) using a very small quantity of pine tree testing powder was proposed, and the influence of discharge current limiting resistance connected in series into a capacitive discharge circuit on ignition energies of explosive powders was investigated. As a result the minimum ignition energy was 42.25mJ when discharge current limiting resistance 300 $k\Omega$.
