Abstract
This study experimentally evaluates the interaction of the oxygen enhanced combustion (OEC) technique with the pulsating combustion technique by the acoustic excitation of flames, the effects of these techniques on atmospheric emissions of CO, NOx, formaldehyde and acetaldehyde, and the temperature of exhaust gases in diffusive and confined natural gas flames. The results showed a general trend of reductions in the emissions of CO and NOx with the enrichment of the oxidant with O2 and also under some conditions with an acoustically excited flame. The results showed that the acetaldehyde emissions decreased with the ratio of equivalence but increased in the presence of acoustic excitation. Formaldehyde emissions showed no significant trend. The results show that the simultaneous application of the OEC and acoustic excitation techniques in a controlled manner can reduce pollutant emissions and increase the efficiency of thermal combustion equipment.
