This research aims to investigate the effects of high-impulse oxygen lancing on nitrogen oxide emissions during oxy-fuel co-combustion.
Conducted experiments using a two burner setup under industrial conditions.
Investigated oxygen enrichments up to 60% and hydrogen enrichments up to 85%.
Measured NOx emissions compared to air-fuel combustion as a baseline.
Evaluated temperature and heat flux profiles for staged and non-staged combustion cases.
Achieved up to 72% reduction in NOx emissions compared to air-fuel combustion.
Demonstrated no negative impact on operational safety or flame stability with choked flow lancing.
Maintained effective temperature and heat flux distribution even at high enrichments.
