Configuration effects of natural gas fired multi-pair regenerative burners in a flameless oxidation furnace on efficiency and emissions

► We executed experiments and simulations for flameless oxidation burner. ► Four combinations of burner were examined to derive out reaction characteristics. ► Single digit of NO and CO occurred together for a parallel burner configuration. ► Smooke reaction model shows reasonable explanation of flameless oxidation. ► However, the reaction kinetics is lower than the experimental results.
