An experimental study focused on emission performance of trapped-vortex combustor (TVC) with liquid fuel under rich-burn quick-quench lean-burn (RQL) mode was performed.The effect of a variety of parameters on emission performance was obtained
such as excess air coefficient of cavity
airflow rate and inlet temperature.The results show that:CO and UHC (unburned hydrocarbon) volume fractions increase as the excess air coefficient of cavity increases (α=0.61~1.53) while NOx volume fraction decreases;the emission performance of the combustor gets worse as airflow rate(Wa=0.4~0.6kg/s)increases
CO
UHC and NOx volume fractions increase;CO and UHC volume fractions decline and NOx volume fraction rises with the increase of inlet temperature (283~473K).
