为研究丙烯气体最小点火能随温度的变化规律,首先采用最小点火能测试系对甲烷气体进行了测试和评估,得到了不同温度下的最小点火能及其随温度的变化趋势。结果表明,可燃气体(或液体蒸气)敏感浓度均略高于其当量浓度。气体最小点火能随温度升高而增大。
In order to study the law of the minimum ignition energy of propylene gas with temperature, the minimum ignition energy of methane gas was tested and evaluated by using the minimum ignition energy test system. The minimum ignition energy at different temperatures and its change trend with temperature were obtained. The results show that the sensible concentrations of flammable gas (or liquid vapor) are slightly higher than their equivalent concentrations. The minimum ignition temperature increases with increasing temperature.
