摘要：The gas turbine combustor with -10# diesel was changed to one with burn natural gas, and based on the principle of least change of combustor, only the fuel nozzle design was changed. In order to understand the matching characteristics of the nozzle and combustor, three kinds of natural gas nozzles with different injector hole diameters were designed, nozzle could affect the injecting velocity of natural gas, natural gas concentration distribution, therefore, it could affect the combustion performance of combustor. So the combustion performance experiment for these three kinds of natural gas nozzles was carried out. The experimental results show that when the fuel is natural gas, the combustion efficiency increases, but the exit temperature distribution is poor, there is little effect on the wall temperature distribution. Based on the comparative analysis of the experimental results, the combustion performance of natural gas nozzle No.3 is the optimum. © 2018, Editorial Department of Journal of Aerospace Power.
