摘要

将中心分级的双环预混旋流(TAPS)燃烧室、单环腔燃烧室(SAC)及双环腔燃烧室(DAC)采用相同的扩压器尺寸、外机匣最大直径以及燃烧室出口尺寸

采用相同的数理模型

对TAPS燃烧室

SAC

DAC进行三维数值模拟.对比研究了TAPS燃烧室

SAC

DAC的总压恢复系数、燃烧效率、燃烧室出口温度分布系数、污染排放等性能参数.研究结果表明:采用TAPS燃烧室

可获得比SAC和DAC更高的总压恢复系数及燃烧效率;比SAC和DAC更低的燃烧室出口温度分布系数及NOx等污染的排放

尤其是设计工况下出口NOx排放.从研究结果来看中心分级的TAPS燃烧室的技术优势十分明显

是一种很有发展前景的高温升、低污染燃烧室.

Abstract

Diffuser

outer case and exit dimensiom kept the same with single annular combustor(SAC)and dual annular combustor(DAC)

redesigned the combustor from a single annular structure into twin annular premixing swirler(TAPS)combustor in central classified.Taking the same physical models(including the turbulence

radiation

spray and emission model)

three-dimensional reaction flow simulation in TAPS combustor

SAC and DAC were developed in the fluent code.The total-pressure recovery coefficient

combustion efficiency

temperature distribution of the combustor exit and NOx/CO emission profiles were calculated.Finally

the capability of TAPS combustor

SAC and DAC were campared.The results show that

by using the TAPS combustor

the total-pressure recovery coefficient

combustion efficiency was improved compared with the SAC and DAC

the temperature distribution coefficient of the combustor exit and NOx emission is lower than SAC and DAC.So the conclusion could be drawed that the technical advantages of TAPS combustor is obvious

and the TAPS combustor is a good high temperature rise and low emission combustor.
