Abstract:This study numerically investigates the combustion characteristics in a swirl burner for CO-H 2 syngas by large eddy simulation. Firstly, experimental data are used to verify the applicability of the Boivin mechanism and the Sandia mechanism. The simulation results show that the Boivin mechanism predicts a more reasonable flame structure. Then, Syngas25, Syngas45, and Syngas100 (composed of 25%, 45%, and 100% H 2 by volume, respectively) are set to numerically investigate the effect of hydrogen addition ratio … Show more
