System and method for integrating sections of a turbine

摘要

A system and method for integrating sections of a turbine (212) are provided. In one system, a turbine (212) includes a last stage bucket section (232) with a first annular outer wall (218) that is angled with respect to a centerline of the turbine (212) at a first angle average (225). The turbine also includes an exhaust diffuser section (214) having a second annular outer wall (244) that is angled with respect to the centerline of the turbine (212) at a second angle average (245) for improving radial swirl (272). The first angle average (225) is greater than the second angle average (245).
