Abstract

Numerical study is conducted to understand the impact of fuel composition and flame radiation in flame structure and their oxidation process in H2/CO synthetic gas diffusion flame with and without CO2 dilution. The models of Sun et al. and David et al., which have been well known to be best-fitted for H2/CO synthetic mixture flames, are evaluated for H2/CO synthetic mixture flames diluted with CO2. Effects of radiative heat loss to flame characteristics are also examined in terms of syngas mixture composition. Importantly contributing reaction steps to heat release rate are compared for the synthetic gas mixture flames of high contents of H2 and CO, individually, with and without CO2 dilution. The modification of the oxidation pathways is also addressed.
