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.
