Abstract
A combustor comprises a hollow body defining a combustion chamber. The hollow body is typically annular in form and includes an outer liner, an inner liner, and an upstream dome plate. The dome plate includes a swirl cup with a mixer disposed therein to provide uniform mixing of fuel and air. The mixer comprises an inner swirler and an outer swirler that are mounted in the swirl cup. The outer swirler includes solid vanes. A shroud surrounds the mixer at the upstream end, which shroud includes an annular fuel chamber. The shroud further includes a number of axial fuel injection fuel injection openings that provide flow communication between the annular fuel chamber and the mixer and radially inject fuel within the mixer.
