摘要

针对使用液态燃料(航空煤油)的富油燃烧/快速淬熄/贫油燃烧(RQL)工作模式驻涡燃烧室排放性能开展了系统的试验研究

分析总结了驻涡区余气系数、进口空气流量和进口空气温度等参数影响RQL工作模式驻涡燃烧室排放性能的变化规律.结果表明:随着驻涡区余气系数增大(α=0.61~1.53)

CO和UHC(未燃碳氢化合物)体积分数升高

NOx体积分数降低;随着进口空气流量增大(Wa=0.4~0.6kg/s)

UHC

NOx体积分数均升高;随着进口空气温度升高(283~473K)

CO和UHC体积分数降低

NOx体积分数升高.

Abstract

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

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).
