The result shows that the content of combustible gas is far lower than the lower explosive limits and there is no the explosiondanger in heating furnace.
研究结果表明，加热炉运行全过程中可燃气体含量较少且远低于烟气混合物爆炸极限，不存在爆炸危险；
2
Using this chart to distinguish the explosiondanger caused by the mixture of gas and air is more complete and accurate than the chart of gas detonation triangle.
采用它判别瓦斯与空气混合气体的爆炸危险性时，比用瓦斯浓度三角形更加全面、准确。
3
The minimum ignition energy, the maximum experimental safe gaps, the degree of explosiondanger and other explosion characteristics were experimentally determined.
