| Abstract: | Measurements of turbulent combustion were conducted in a test facility for combustor with staged air injection.The effects of flow rate ratio of the staged air injection or secondary air ratio on the combustion and NO_x formation were investigated.The distributions of gas temperature and O_2, CO_2,CO,and NO concentrations were obtained for four cases of secondary air ratio. |

| Keywords: | turbulent combustion combustor with staged air injection flow rate ratio of secondary air NO_x formation |
