Abstract:
The present invention relates to a burner device for a gas turbine. The burner device comprises a burner body (120), wherein the burner body (120) comprises an axial end face (123). The burner body (120) further comprises a first supply channel (121) which has a first opening in the axial end face (123). The burner device further comprises a burner end element (100) which is arranged at the axial end face (123). The burner end element (100) comprises a first plenum chamber (101) which is coupled to the first opening of the first supply channel (121), such that a first fluid is feedable from the first supply channel (121) to the first plenum chamber (101). The burner end element (100) further comprises a lattice structure (103) with a plurality of interconnected pores, wherein the first plenum chamber (101) is coupled to the lattice structure (103) for feeding the first fluid into the lattice structure (103). The lattice structure (103) forms a part of a burner surface (104) which points to a burning chamber (140) of the gas turbine such that a fluid connection between the burning chamber (140) and the lattice structure (103) is formed.
Abstract:
A combustor for a gas turbine engine comprises a combustion chamber having a pilot injector at one end and at least one main injector spaced radially from the pilot injector. The main injector includes a fluid flow path with a plug that restricts flow at least at an interior portion of the flow path. A gas turbine engine is also disclosed.
Abstract:
A fuel nozzle apparatus (10) for a gas turbine engine includes: a fuel discharge element (24) having a discharge orifice (50) communicating with a fuel supply connection (104); a static supporting structure (36); and a cantilevered flexible support structure (110) interconnecting the supporting structure (36) and the fuel discharge element (24), the flexible support structure (110) having a first end connected to the static supporting structure (36), and a second end connected to the fuel discharge element (24).
Abstract:
A direct contact heat exchanger assembly is provided. The direct contact heat exchanger includes an evaporator jacket and an inner member. The inner member is received within the evaporator jacket. A sleeve passage is formed between the evaporator jacket and the inner member. The sleeve passage is configured and arranged to pass a flow of liquid. The housing has an inner exhaust chamber that is coupled to pass hot gas. The inner member further has a plurality of exhaust passages that allow some of the hot gas passing through the inner exhaust chamber to enter the flow of liquid in the sleeve passage.
Abstract:
Combustion systems for a gas turbine engines are provided. The combustion system is configured to provide a fuel-air mist to achieve light-off during high altitude start (e.g., at altitudes greater than 45,000 ft.) without flame out. The combustion system may also be configured to provide additional air to the combustion chamber at high altitude to facilitate flame propagation and second stage burn.
Abstract:
A pilot liquid tube having a pilot liquid fuel inlet, a pilot liquid fuel conduit, a pilot liquid fuel nozzle, and a shroud configured to shield the pilot liquid fuel nozzle. The pilot liquid tube may be installed and/or removed from an injector of a gas turbine engine while the shroud remains fixed to pilot liquid fuel conduit.
