| description | A combustion apparatus for a gas turbine engine including a combustor structure (12) having at least one combustion chamber (14), a dual cone fuel nozzle (24) for injecting both fuel and water to the combustion chamber (14), and a swirl cup package (22) upstream of and adjacent to the combustion chamber (14). The swirl cup package (22) further includes a swirler (28) and a venturi (34) extending between the fuel nozzle (24) and the combustion chamber (14) for mixing the fuel and water with air. The venturi (34) is configured to have a thickness (t) from an upstream end (44) to a downstream end (46) which provides a heat transfer conduction path that reduces axial stresses imposed on the venturi (34) when water impinges on an upstream portion of the venturi (34). |
