The statistical analysis of the experimental data indicates that the different position and amount of secondary air supplied can affect the discharging level of NOX from gas cookers, and that NOX is formed easily provided the secondary air enters reaction zones through flame roats. In this paper, we have also made research on the geometric factors of secondary air shad (SAS) in order to decrease NoX and CO emission, Simultaneously,we have given the theoretical explanation for the results. We reacned the conclusion that SAS is feasible and NoX reducing is effective.
