Abstract
A fuel injector for a gas turbine includes an outer air path having a converging exit portion, and a fuel path inboard of the outer air path. An inner air path inboard of the fuel path includes an outer wall having a converging exit region and surrounds an axial core duct defining an axial air path having a diverging exit region. The inner air path creates a pressure drop near a fuel injection opening to promote mixing and atomization of fuel over a range of power levels, including low power operation.
