在固定碳氧比（C/O）为0.50，压力为40 mbar的条件下，以乙烷-氧-氩气混合物为燃料，乙烷以摩尔分数为25%，50%和75%的二甲氧基甲烷（DMM）或碳酸二甲酯（DMC）逐渐取代乙烷，研究了两组层流预混火焰。采用同步加速器真空紫外光电离的分子束质谱法获得了火焰的摩尔分数。建立了乙烷、DMM和DMC的详细动力学模型，并根据火焰测量结果进行了测试。研究了向物种库中添加氧化物的影响，特别是考虑了有害排放物和相关中间体的峰值摩尔分数。结果表明，燃料对的变化行为主要与“体积效应”有关，燃料对之间没有很强的化学相互作用。在添加量相同的情况下，DMM和DMC对煤烟前驱体的抑制效果相当。在这两个火焰系列中，甲醛是主要的含氧排放物，随着DMM或DMC的加入几乎呈线性增加，这是两种含氧物的结构和动力学特性的结果。
Two series of laminar premixed flames fueled by ethane-oxygenate-argon mixtures, in which ethane was incrementally replaced with either dimethoxy methane (DMM) or dimethyl carbonate (DMC) by mole fractions of 25%, 50% and 75%, were investigated at a fixed carbon to oxygen ratio (C/O) of 0.50 and a pressure of 40 mbar. Mole fractions for flame species were obtained by employing molecular-beam mass spectrometry with synchrotron vacuum ultraviolet light for ionization. A detailed kinetic model including the chemistry of ethane, DMM and DMC was constructed and tested against the flame measurements. The effects of the addition of oxygenates to the species pool were studied, especially considering peak mole fractions of harmful emissions and relevant intermediates. The results indicate that the variation behaviors are mainly related to “volume effects” without strong chemical interactions between the fuel pairs. DMM and DMC show comparable performance in inhibiting soot precursors with the same addition amount. Formaldehyde is a major oxygenated emission in both flame series, almost linearly increasing with the addition of DMM or DMC, which is the consequence of the structural and kinetic characteristics of both oxygenates.
