ABSTRACT:
Lean direct injection is used in a gas turbine combustor to reduce NO.sub.x emissions. The combustor has a plurality of fuel jets for tangentially injecting fuel and a plurality of air jets for tangentially injecting air therein. The fuel jets and the air jets are preferably disposed in a common cross-sectional plane, although additional groups of fuel and air jets in other planes can be provided. The jets are all evenly spaced and alternate between fuel and air jets. All of the jets preferably point in the same circumferential direction. Alternatively, the jets can be arranged so that all fuel jets are located in a first cross-sectional plane, and all air jets are located in a second cross-sectional plane. Preferably, the fuel jets point in one circumferential direction while the air jets point in the opposite circumferential direction.
