摘要：

The most important reactions in the reduction of NO in reburn zones have been identified for several reburning fuels at low temperatures. This has been accomplished through the analysis of reaction rates and sensitivity in kinetic plug flow calculations simulating the gas reburning process. The kinetic model developed is evaluated through comparisons with experimental data. Acetylene, ethylene, ethane, methane, and natural gas have been studied at various temperatures between 973 and 1373 K. The major NO removal pathway is found to be the HCCO + NO reaction in all cases. Critical to the modeling are the branching fraction of this reaction and the competition for vinyl between dissociation and reaction with molecular oxygen. These points are discussed in detail.
