TRANSITION DUCT ASSEMBLY WITH LATE INJECTION FEATURES

摘要

A turbomachine 10 includes a plurality of transition ducts 50 disposed in a generally annular array. Each of the plurality of transition ducts 50 includes an inlet 52 an outlet 54, and a passage 56 defining an interior 57 and 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 each of the plurality of transition ducts 50 is offset from the inlet 52 along the longitudinal axis 90 and the tangential axis 92. The turbomachine 10 includes a support ring assembly downstream of the plurality of transition ducts 50 along a hot gas path 104, and a plurality of mechanical fasteners 200 connecting at least one transition duct 50 of the plurality of transition ducts 50 to the support ring assembly. The turbomachine 10 includes a late injection assembly 210 providing fluid communication for an injection fluid to flow into the interior 57 downstream of the inlet 52 of at least one transition duct 50 of the plurality of transition ducts 50.
