Combustion Characteristics of Flameless Combustion by Reactants Injection Conditions

Journal of the Korean Society of Combustion, 2013
The flameless combustion has been considered as one of the promising combustion technology for high thermal efficiency, reducing NOx and CO emissions. In this paper, the effect of air and fuel injection condition on formation of flameless combustion was analyzed using three dimensional numerical simulation.

Combustion Mode and Reactivity of Methane Fuel in Hot O2/CO2/N2 and O2/H2O/N2 Coflows in a Nonpremixed Small‐Scale Tube Burner

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
The reactivity of methane fuel was numerically studied to compare the effects of CO2 and H2O dilution of hot oxidizer atmospheres on combustion modes and flame characteristics. A nonpremixed small scale burner at 8.6 kW thermal load forming central fuel jet flame in coflow oxidizer atmosphere was employed.
