Abstract: A double skinned feed or scavenge pipe assembly comprises; an inner pipe (22) and an outer pipe (23) enclosing the inner pipe and defining an annular space (24) between the inner pipe and the outer pipe and a sleeve (28) configured to slip over the outer pipe (23). Complementary threads (29) are provided on an outer wall of the outer pipe (23) and an inner wall of the sleeve (28). A lock, for example in the form of a locking nut (31) is positioned over the outer pipe (23) when the complementary threads (29) of the outer pipe and sleeve are engaged. The configuration of the assembly is such that, in use, the sleeve (28) is slidable between a first position where the inner pipe (22) is accessible and a second position wherein the inner pipe (22) is completely enclosed.

Abstract: The present invention relates to a turbo air blower having waterproof and damp-proof functions. The turbo air blower has a waterproof structure so as to be installed outdoor, thereby obviating the need to add a pressure-feeding line and manufacture an air blower room which are required for conventional indoor installation. Further, the turbo air blower has a reliable damp-proof function by installing various dehumidifying parts therein, thereby being capable of preventing a device from being corroded by humidity and dampness as well as providing dehumidified pressure-fed air.

Abstract: An axial fuel staging injector for a gas turbine includes a body. The body includes an upstream end and a downstream end. The body defines a primary compressed air flow path through which compressed air flows from a compressed air source to a transition duct of a gas turbine combustor. The body includes a plurality of outlets disposed on an interior surface thereof. Each outlet of the plurality of outlets includes a secondary fuel conduit in fluid communication with a secondary fuel source, and includes a first wall that defines a secondary fuel path. The secondary compressed air conduit is in fluid communication with a compressed air source, and includes a second wall disposed about the first wall in a substantially coannular arrangement, wherein the first wall and the second wall define a secondary compressed air flow path. Each outlet is configured to inject a secondary fuel and compressed air into the primary compressed air flow path in a direction transverse to the primary compressed air flow path forming a fuel-air mixture.
