摘要:
采用1.2 L 哈特曼管最小点火能测试装置，研究了中位径为32 μm的石松子粉的最小点火能量随粉尘浓度、点火延时以及喷粉压力之间的变化规律。试验结果表明：在环境温度为(25±5 )℃，环境湿度为30%±5%的条件下，石松子粉的最佳着火浓度750 g/m3，最佳点火延时为90 ms，最佳喷粉压力为0.8 MPa，此时石松子粉的最小点火能达到极小值。在相同的实验条件下有电感的点火方式比无电感的点火方式所需的能量要小。在有电感存在的情况下，石松子粉的最小点火能为10 mJ；在无电感存在的情况下，石松子粉的最小点火能为15 mJ，说明石松子粉对电火花较敏感。
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.
