A reduced chemical kinetics including 20 species and 16 global reactions was obtained by reducing the detailed kinetics for ethylene combustion with the method of quasi-steady state approximation(QSSA).Experimental measurements of a laminar premixed ethylene/O2/Ar flame were carried out on the combustion station at National Synchrotron Radiation Laboratory(NSRL) to validate the kinetics.One-dimensional numerical method was implemented to simulate the test.Comparison with each other shows that the reduced kinetics has the ability to represent efficiently the reaction mechanisms of detailed element reaction model.Some difference between the experimental data and calculated results with detailed kinetics indicates the modifications of the detailed kinetics is needed.
