Through three-dimensional simulation of UG for a heavy-duty gas turbine combustor, three-dimensional calculation and analysis are carried out about the nozzle structure and the NOx emissions of combustion chamber by using the Fluent code.The finite element Rate and PDF combustion model, Realizable k-ε turbulence model, SIMPLE pressure-velocity coupling and two precision upwind difference format are adopted at the same time.Under the condition of different power, the flow field, combustion efficiency, radial outlet temperature quality, pollutants emissions of NOx and CO have been simulated and calculated.The results are in accordance with the experimental data, which provides the theoretical basis for heavy-duty gas turbine design and its improvement.
