The structures of three laminar premixed stoichiometric flames at low pressure (6.7 kPa): a pure methane flame, a pure ethanol flame and a methane flame doped by 30% of ethanol, have been investigated and compared. The results consist of concentration profiles of methane, ethanol, O, Ar, CO, CO, HO, H, CH, CH, CH, CH, CH, -CH, -CH, CHO, CHHCO, measured as a function of the height above the burner by probe sampling followed by on-line gas chromatography analyses. Flame temperature profiles have been also obtained using a PtRh (6%)-PtRh (30%) type B thermocouple. The similarities and differences between the three flames were analyzed. The results show that, in these three flames, the concentration of the C intermediates is much larger than that of the C species. In general, mole fraction of all intermediate species in the pure ethanol flame is the largest, followed by the doped flame, and finally the pure methane flame.
研究并比较了三种低压（6.7 kPa）层流预混化学计量火焰的结构：纯甲烷火焰、纯乙醇火焰以及掺杂30%乙醇的甲烷火焰。结果包括甲烷、乙醇、O、Ar、CO、CO、HO、H、CH、CH、CH、CH、CH、-CH、-CH、CHO、CHHCO的浓度分布，这些是通过探针采样并随后进行在线气相色谱分析来测量的，测量结果作为燃烧器上方高度的函数。还使用PtRh（6%）-PtRh（30%）B型热电偶获得了火焰温度分布。分析了三种火焰之间的异同。结果表明，在这三种火焰中，C中间体的浓度远大于C物种的浓度。一般来说，纯乙醇火焰中所有中间物种的摩尔分数最大，其次是掺杂火焰，最后是纯甲烷火焰。
