摘要
In order to design a dual-fuel combustor for the Chemically Recuperated Gas Turbine (CRGT), numerical research on the performance of a can annular combustor is presented in this paper. The objective is to understand the impact of different actual operating conditions on combustion and emission performance. The load of the combustor is varied from 30% to 100%. The mathematical models used for fuel combustion consist of the realizable k-e model for turbulent flow, discrete phase model (DPM) for tracking the oil droplet path lines, probability density function (PDF) model for non-premixed oil combustion and pollution model for nitrogen oxides (NOX) emission. The obtained results using these models show good agreement with other experimental results. The effects of different conditions on the flow field, flame shape, gas temperature and NOX emission are presented in this paper. The results obtained in this study show the change in gas turbine can annular combustor performance with different actual operating conditions.
