摘　　要：为了解生物质气再燃还原燃煤NOx的机理,建立了充分搅拌反应器(PSR)和柱塞流反应器(PLUG)串联的反应器网络,利用CHEMKIN软件对该过程进行了数值模拟,并通过生成率分析(Rate-of-production analysis)和敏感性分析(Sensitivity analysis)对实验规律作出了解释。不同工况条件下的模拟结果与相应实验结果的比较表明:所建串联网络和所选用5元素、145组分、1006基元反应的机理是切实有效和可行的,用这种方法可以初步预测和模拟生物质气再燃还原燃煤NOx的还原效果。To understand the mechanisms of NOx-reduction through reburning of biogas, a reactor network composed of a perfectly stirred reactor （PSR） in series with a plug-flow chemical reactor （PLUG） was established and CHEMKIN code was employed to numerically simulate the process of NOx-reduction through reburning of biogas.At the same time,the experimental laws were explained through Rate-of-Production Analysis and Sensitivity Analysis.Comparing the simulation results with the experimental data under different conditions shows that the reactor network and the mechanism used here are appropriate choice,and the result or process of NOx-reduction through reburning of biogas can be forecasted or simulated approximately in this method.
