Abstract: The effect of the air jet with oblique angle on combustion efficiency, fuel-lean limit and temperature profile at the combustor exit was investigated experimentally. A combustor with an axisymmetric air jet was also investigated for making a comparison. Results show that fuel-lean limit and combustion efficiency can be improved evidently in the combustor with an. oblique air jet, and that the combustor performance with jet oblique angle of 15° is much better than that with jet oblique angle of 10°.
