实验对甲烷、丙烷和60％甲烷/40％丙烷(气体体积百分数)的火焰传播速度进行了测量。实验在室温和大气压下采用圆管法进行。结果表明,60％甲烷/40％丙烷的层流火焰传播速度在相当宽的当量比范围内,夹于甲烷和丙烷的层流火焰传播速度之间。对这个现象,文章用对火焰传播速度起决定作用的阿仑尼乌兹因子作了粗略的分析。实验还发现,在富燃料区,混合燃料的火焰传播速度将大于甲烷或丙烷的火焰传播速度。
The flame propagation velocity of methane, propane and 60% methane / 40% propane (gas volume percent) was measured. Experiments were performed at room temperature and atmospheric pressure using a round tube method. The results show that the laminar flame propagation velocity of 60% methane / 40% propane is within a fairly wide equivalence ratio, which is sandwiched between laminar flame propagation velocities of methane and propane. For this phenomenon, the article made a rough analysis of the Arrhenius factor, which plays a decisive role in the propagation speed of flame. Experiments also found that in the fuel-rich zone, the flame propagation velocity of the mixed fuel will be greater than the flame propagation velocity of methane or propane.
