    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.
