摘要

保持扩压器尺寸、外机匣最大直径以及燃烧室出口尺寸不变

将燃烧室分别设计为单环腔燃烧室(SAC)、双环腔燃烧室(DAC)、双环预混旋流(TAPS)燃烧室、中心分级燃烧室(CSC)和三旋流燃烧室(TSC)5种燃烧室结构

保持湍流、喷雾、燃烧、辐射及排放数理模型不变

对5种燃烧室进行三维数值模拟.对比研究了5种燃烧室的污染排放性能.结果表明:采用分级燃烧的DAC慢车状态下CO排放量最低

采用DAC在慢车状态下的CO排放量比SAC降低了近62%.采用分层燃烧的TAPS燃烧室的NOx排放量最低

采用TAPS的NOx排放量比SAC降低了近43.5%.

Abstract

The dimension of diffuser

maximum diameter of outer casing and dimension of combustor exit were kept the same

and the combustor was designed as single annular combustor(SAC)

dual annular combustor(DAC)

twin annular premixing swirler(TAPS) combustor

center staged combustor(CSC)and triple-swirler combustor(TSC). The mathematical models(including the turbulence

spray

combustion

radiation and emission) were kept the same

and three-dimensional numerical simulation of five different combustors were developed to compare and study the pollution emission performance of five different combustors. The results show that

the CO emission value of the staged DAC in idle operation is the lowest

and the CO emission value of DAC is 62% lower than that of SAC. NOx emission value of the stratified TAPS combustor in design state is the lowest

and the NOx emission value of TAPS combustor is 43.5% lower than that of SAC.
