摘要：In order to control the chemical reaction process to the benefit of the direction of NOx reduction, the further research and discussion on NOx reduction mechanism with gas fuels was performed. Based on the detailed chemical kinetic mechanism of Glarborg(2000), reaction mechanism of NOx reduction (RMNR) was constructed. It consists of 362 elementary reactions and 62 chemical species and applies to study NOx reduction with gas fuels including H-2, CO, CH4, pyrolysis gas and so on. And the chemical reactions characteristics of fuels were also explored. The RMNR simulation results show that the chemical characteristics of NOx reduction with different kinds of gas fuels can well be predicted. The effects of main elementary reactions on NOx reduction are analyzed through the use of reaction sensitivity coefficient. As it involves a number of oxidation and reduction reactions in the process of NOx reduction, the quantitative effects of NOx reduction can not be completely and accurately simulated. Therefore, NOx reduction mechanism of gas fuels needs to be constantly studied and improved.
