摘要
Abstract
In order to obtain the changing regularity of the minimum ignition energy with dust concentration, ignition delay and dusting pressure, lycopodium with the median diameter of 32μm was experimentally studied by 1.2 L Hartmann tube minimum ignition test device. The results have shown that the optimum ignition concentration is 750 g/m3 and the optimum ignition delay is 90ms, the best dusting pressure is 0.8MPa under the temperature of (25 ±5) ℃ and ambient humidity of 30% ±5% , just when minimum ignition energy of lycopodium reaches its minimum value. Energy required for inductance ignition is smaller than the non-inductive under the same experimental conditions. The minimum ignition energy of lycopodium is 10 mJ in the presence of inductance, while it is 15 mJ with non-inductive, implying that lycopodium is sensitive to the electric spark.关键词
