摘要:
A fuel injection assembly (126) for use in a turbine engine (100) is provided. The fuel injection assembly includes a plurality of tube assemblies (202) wherein each of the plurality of tube assemblies includes a plurality of tubes (204). At least one injection system (206) is coupled to at least one tube assembly of the plurality of tube assemblies. The injection system includes a fuel delivery pipe (208) and a fluid supply member (210) coupled to the fuel delivery pipe, wherein the fluid supply member is positioned a predefined distance (220) upstream from the tube assembly and includes at least one first portion (211) having an annular end portion (216). The annular end portion includes at least one opening (302) for delivering fluid toward the tube assembly for reducing dynamic pressure oscillations and/or reducing the temperature within a combustor (124) during operation of the turbine engine.

A combustor (2) for a gas turbine engine includes a plurality of primary nozzles (6) configured to diffuse or premix fuel into an air flow (54) through the combustor; and a secondary nozzle (102) configured to premix fuel with the air flow. Each premixing nozzle includes a center body (106), at least one vane (108,140), a burner tube (122) provided around the center body, at least two cooling passages (116), a fuel cooling passage (116) to cool surfaces of the center body and the at least one vane, and an air cooling passage (96) to cool a wall of the burner tube. The cooling passages prevent the walls of the center body, the vane(s), and the burner tube from overheating during flame holding events.

A premixing apparatus (110) for a gas turbine system includes non-swirl elements (220) around a face (210) of the premixing apparatus (110) and one or more swirl assemblies (230) located on the face. The non-swirl elements (220) premix a premixture prior to the premixture being delivered to a combustor of the gas turbine system. Each swirl assembly (230) disturbs a flow of fluid prior to the fluid being delivered to the combustor. The premixture includes fuel and oxidant, and the fluid disturbed by the swirl assembly (230) includes the oxidant or the premixture.
摘要:
A combustor section (10) is provided and includes a segmented annular manifold (20) mounted upstream from a fuel nozzle support (60) in a section of a passage through which an oxidizer flows, each segment (201,202,203,204) of the manifold being substantially axially aligned and including a body to accommodate fuel internally that is formed to define injection holes through which the fuel is injected into the passage through which the oxidizer flows upstream of the fuel nozzle support.
