在过去的几十年里，在从柴油机到燃煤锅炉的各种类型的燃烧室中，燃料在增强氧气气氛下的燃烧得到了很好的研究。大多数研究发现，在氧煤燃烧过程中，NOx的排放量显著降低。本文采用详细的动力学模型对O2/CO2气氛和空气气氛下NOx的燃烧化学进行了研究。通过计算结果与实验数据的比较，选择了合适的反应机理。考察了各种参数(温度、CO2浓度)对NOx转化率的影响。研究了高浓度CO2对NO生成和破坏过程的化学影响。通过对基本化学反应的研究，可以得出结论：高浓度的CO2对NOx转化过程有明显的影响。此外，还讨论了在不同气氛下NO生成和破坏的主要反应步骤以及NO还原的最重要反应。
Combustion of fuels under enhanced oxygen atmospheres has been well investigated over the past decades in various types of combustors, varying from diesel engines to coal-fired boilers. Most studies have found significantly lower NOxemissions during Oxy-coal combustion. In this paper, NOxcombustion chemistry under O2/CO2atmosphere as well as air atmosphere was studied using detailed kinetic model. A suitable reaction mechanism was chosen based on the comparison between the calculation result and the experimental data. The influence of various parameters (temperature, CO2concentration) on NOxconversion was investigated. The chemical effects of high CO2concentration on NO formation and destruction process was studied. On the basis of investigations through elementary chemical reactions, it can be concluded that high CO2concentration play a pronounced role on NOxconversion process. Moreover, the dominant reaction steps contribution to production and destruction of NO as well as the most important reactions for NO reduction under different atmospheres were discussed.
