The direction of fuel injection in a gas turbine combustor has significant effects on the performance, especially on its flame blow-off characteristics. combustion by two kinds of fuel injection nozzles in the same combustion liner was investigated experimentally by measuring the temperature and gas composition. The combustor with one of the fuel nozzles, which injects fuel inward around the center axis, shows good performance for weak mixture conditions, but experienced a sudden blow-off of the flame at high pressure conditions. Present results revealed that it has a poor flame holding structure without recirculation of hot gas at the moderate mixture condition; whereas it has a stable diffusion type flame at the lean mixture condition. The accuracy and the nature of the obtained temperature and the gas concentration data were discussed.
