A test for electrical ignitions of flammable dust clouds

Measurement of minimum ignition energies of dust clouds in the <1mJ region

“…Eckhoff [2], on the other hand, was able to ignite the dust at 0.3 mJ, which was the lower energy limit of the spark generator. Using a break-flash spark generator, Bennett et al [23] found the MIE of sulphur dust to be similar to that of ethylene.…”

MIKE 3 versus HARTMANN apparatus: Comparison of measured minimum ignition energy (MIE)

“…Nifuku and Katoh [7] showed that the feeding time and the feeding rate of the ignition energy influence considerably the ignition of a dust cloud. This was confirmed either by Randeberg et al [18], or by Bennett et al [8] who demonstrated through a literature review [13][14][15][16][17] how adding either a larger inductance or a larger resistance can increase the spark duration and thus decrease the MIE of a given dust. This is confirmed by Fig.…”

“…This is due to the difficulty to quantify and reproduce experimentally real-world spark characteristics and especially sparks duration and synchronisation between dust dispersion and sparkover [6][7][8][9][10] (see discussion in Section 3.2). However, it is not possible to accurately qualify the ignition sensitivity of a sample according to the test result.…”

Pyrolysis Characteristic and Ignition Energy of High-Density Polyethylene Powder

“…MIE는 부유 분진을 착화시키는데 필요한 최소 한의 에너지로, 규격화된 시험법에 의한 측정방법이 제안되고 있다 [5,6]. MIE의 측정에 영향을 주는 조 건은 많이 있지만, 특히 분진의 입경과 농도 변화에 따라 측정값이 크게 영향을 받으므로, MIE의 조사 시에는 이를 고려해야 한다 [7][8][9][10][11] …”
