The overall process performance and efficiency can also be improved

The disparity in the Kext’s between the N2-diluted Syngas-6/air flames and N2∗-diluted ones was found to be less than 1%, which indicated that the chemical effect on Kext reduction caused by the N2 dilution is negligible.
5. Concluding remarks
The dilution effects of N2 and CO2 on the propagation and extinction of lean premixed H2/CO/air flames were experimentally and numerically investigated.
