Abstract: A system includes an exhaust diffuser system having an axial-radial diffuser and a transition duct. The axial-radial diffuser includes an inlet, an outlet, an axial diffuser portion between the inlet and the outlet, and a radial diffuser portion between the axial diffuser portion and the outlet, wherein the inlet is configured to couple to a gas turbine system. The transition duct is coupled to the axial-radial diffuser, wherein the outlet is disposed inside of an intake portion of the transition duct, and the transition duct includes a discharge portion configured to couple to a heat recovery steam generator (HRSG).

Abstract: A turbine disc assembly is provided. The turbine disc assembly includes a first rotor disc, a second rotor disc, and a spacer disc coupled between the first and second rotor discs along an axis to define a plenum. The spacer disc has an inner surface with a radius from the axis. A first cooling channel defined between the first rotor disc and the spacer disc is in flow communication with the plenum. The second rotor disc includes a deflector having a deflection surface positioned within the plenum such that the deflection surface is oriented towards the first cooling channel at an acute angle relative to the radius of the inner surface of the spacer disc.

Abstract: A gas turbine casing with an internal heat exchange system. The gas turbine extends between an inlet section and an exhaust section and defines a downstream direction from the inlet section to the exhaust section. The casing includes a forward end, an aft end downstream of the forward end, a first exterior surface facing radially outward, a second exterior surface facing radially inward, and an internal body at least partially defined between the first exterior surface and the second exterior surface. The heat exchange system includes an inlet and an outlet formed in an exterior surface of the casing proximate the aft end, a supply bore extending upstream from the inlet through the interior body of the casing, and a return bore extending downstream to the outlet through the interior body of the casing.
