本文对吡啶和吡咯在富氧条件下的氧化反应进行了研究。实验结果表明，当温度高于800 ℃时，随着温度的升高，尾气中N2 O浓度迅速分解，主要转化为N2-。NO和N_2O的浓度都可以增加，这明显是由于氧浓度的增加。此外，气氛对吡咯氧化的影响与对吡啶氧化的影响有很大不同。富氧燃烧中高含量CO2的引入会导致燃料氮的迁移发生一定的变化。
In this article, a study on pyridine and pyrrole oxidation under oxy-fuel conditions has been carried out. The experimental results indicate that when the temperature is above 800 degrees C, concentration of N2O in the offgas quickly destructs mainly into N-2 with the increase of temperature. Both NO and N2O concentrations can be enlarged, obviously due to the increase of oxygen concentration. In addition, the effect of gas atmosphere on pyrrole oxidation is quite different from that on pyridine oxidation. Introduction of high content CO2 in oxy-fuel combustion can lead to a certain migration change of fuel nitrogen.
