Summary: | PROBLEM TO BE SOLVED: To provide a diffuser configured to receive exhaust gas from a turbine.SOLUTION: An upstream end of an outer barrel (50) of the diffuser includes an upstream lip (96) interfacing with a downstream lip (128) of an outer wall (106) of a turbine outlet (20), forming a lap joint. The outer barrel (50) includes a plurality of axial segments (184) disposed between the upstream end of the outer barrel (50) and an outer aft plate (62), and the axial segments. An inner barrel (48) includes a plurality of axial segments (184) disposed between an upstream end (102) of the inner barrel (48) and a seal interface (140). The seal interface (140) includes a groove configured to receive an inner aft plate (63). Poles are spaced about a turbine axis (76) and couple an end of the outer aft plate (62) to an end of the inner aft plate (63).SELECTED DRAWING: Figure 1
【課題】タービンから排気ガスを受け取るように構成されたディフューザを提供する。【解決手段】ディフューザの外筒(50)の上流側端部は、タービン出口(20)の外壁(106)の下流側リップ(128)と接合する上流側リップ(96)を含み、重ね継手を形成する。外筒(50)は、外筒(50)の上流側端部と外側後方プレート(62)との間に配置された複数の軸方向セグメント(184)、および軸方向セグメントを含む。内筒(48)は、内筒(48)の上流側端部(102)とシール接合面(140)との間に配置された複数の軸方向セグメント(184)を含む。シール接合面(140)は、内側後方プレート(63)を受け入れるように構成された溝を含む。ポールは、タービン軸(76)の周りに離間して配置され、外側後方プレート(62)の端部を内側後方プレート(63)の端部に結合する。【選択図】図1 |
