Abstract
A late lean fuel injection nozzle for a gas turbine includes a first outer air supply tube having a relatively large inner diameter and an outlet at a distal end thereof. The first outer air supply tube is adapted to supply air to a combustion chamber, and at least one fuel injection tube having a relatively smaller diameter enters a distal end portion of the first outer air supply tube and extends within the first outer air supply tube substantially to the outlet.
