    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.
