摘要:
A turbine system (10) is disclosed. In one embodiment, the turbine system includes a transition duct (50). The transition duct (50) includes an inlet (52), an outlet (54), and a passage (56) extending between the inlet (52) and the outlet (54) and defining a longitudinal axis, a radial axis, and a tangential axis. The outlet (54) of the transition duct (50) is offset from the inlet (52) along the longitudinal axis and the tangential axis. The transition duct (50) further includes an interface feature (142) for interfacing with an adjacent transition duct (50). The turbine system (10) further includes a flexible seal (140) contacting the interface feature (142) to provide a seal between the interface feature (142) and the adjacent transition duct (50). The flexible seal (140) includes a sheet (150) having a first surface, an opposing second surface, and a peripheral edge therebetween.

A combustor assembly (102) for use in a gas turbine engine is provided. The combustor assembly (102) includes a combustor liner (126) comprising a slot (502) that at least partially circumscribes the combustor liner. The slot is defined adjacent to a venturi throat region (146) defined within the liner, and a restrictor plate (150) comprises at least one aperture (308) defined therein, the restrictor plate being removably coupled within the combustor assembly such that the restrictor plate is inserted within the slot and extends at least partially across the venturi throat region.

Turbine systems are provided. In one embodiment, a turbine system includes a transition duct 50 comprising an inlet 52, an outlet 54, and a duct passage 56 extending between the inlet 52 and the outlet 54 and defining a longitudinal axis, a radial axis, and a tangential axis. The outlet 54 of the transition duct 50 is offset from the inlet 52 along the longitudinal axis and the tangential axis. The duct passage 56 includes an upstream portion 140 and a downstream portion 142. The upstream portion 140 extends from the inlet between an inlet end and an aft end. The downstream portion 142 extends from the outlet between an outlet end and a head end. The turbine system further includes a joint 160 coupling the aft end of the upstream portion 140 and the head end of the downstream portion 142 together. The joint 160 is configured to allow movement of the upstream portion 140 and the downstream portion 142 relative to each other about or along at least one axis.

摘要:
A system for supplying an injection fluid to a combustor is disclosed. The system includes a transition duct (50) comprising an inlet (52), an outlet (54), and a passage (56) extending between the inlet (52) and the outlet (54) and defining a longitudinal axis (90), a radial axis (94), and a tangential axis (92). The outlet (54) of the transition duct (50) is offset from the inlet (52) along the longitudinal axis (90) and the tangential axis (92). The passage (56) defines a combustion chamber (58). The system further includes a tube (160) providing fluid communication for the injection fluid to flow through the transition duct (50) and into the combustion chamber (58).
