Performance of an interstage turbine burner with an acoustic energy nozzle was investigated experimentally.The experimental result shows that the air excess coefficient of lean blowout is in the range of 25~35 under the condition of Mach number being 0.20~0.40

and the range of stable combustion is relatively wide.The uniformity of outlet temperature distribution is improved with the increase of air excess coefficient.The combustion efficiency is in the range of 96%~98%

and it decreases as the air excess coefficient decreases.Inlet Mach number has little effect on ignition performance

lean blowout performance

outlet temperature distribution and combustion efficiency.The maximum wall temperature locates on the after-wall of the cavity.The total pressure loss coefficient is in the range of 0.03~0.11

and it is about 0.015 higher in hot state than in cold state.The emission index of CO is in the range of 20~46 and that of NOx is in the range of 0.9~2.1.The inlet Mach number and air excess coefficient both have significant effect on the pollutant emission.
