    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.
