Abstract
PURPOSE: To cool the back side of transition piece effectively by regulating air flow introduced thereinto, through provision of ducts and duct stays to the transition piece.
CONSTITUTION: Ducts 8 is provided on the outer surface of transition piece on the back side 1B near the turbine nozzle to form a conduit extending from the side face to the back face of the transition piece, and the ducts 8 are fixed directly to the transition piece by means of duct stays 9. By the flow regulating function of these duct 8 and duct stays 9, air passed along the side face of transition piece after being deflected by the front face 1A flows uniformly along the back-side surface of transition piece without causing separation. Further, since these ducts 8 and duct stays 9 are fixed directly to the transition piece, they also serve as fins so that back side of the transition piece can be cooled effectively and therefore temperature difference on the back side and the front side of the transition piece can be minimized. Thus, since temperature at the outlet of transition piece can be made uniform, it is enabled to improve reliability of gas turbine and to operate the same at a higher temperature.
