A system includes a diffuser section comprising an outer barrel, an outer aft plate, an inner barrel, an inner aft plate, and a plurality of poles, where the outer aft plate is disposed at a downstream end of the outer barrel, the inner aft plate is disposed at a downstream end of the inner barrel, the outer barrel and the inner barrel are disposed about a turbine axis, the diffuser section receives an exhaust gas from a gas turbine, the plurality of poles is circumferentially spaced about the turbine axis, and each pole of the plurality of poles couples a downstream end of the outer aft plate to a downstream end of the inner aft plate.

System of supporting turbine diffuser

A thermal acoustic insulation structure including: a metal internal sheet having an exposed surface configured to be exposed to a hot gas, an external sheet and an insulation sandwiched between the internal and external sheets; a bar secured to the metal internal sheet and extending through at least a portion of the insulation; a bracket connected to the external sheet or to a support plate extending from the external sheet, wherein the bracket includes an opening configured to receive an end of the bar; a fastener securing the end of the bar to the bracket, and an insulating washer separating the bracket from the bar and the fastener.

Thermal and acoustic insulation assembly and method for an exhaust duct of a rotary machine

A system includes a diffuser configured to receive exhaust gas from a turbine. The diffuser includes an outer barrel, an inner barrel, a seal interface, an outer aft plate, an inner aft plate, and poles. An upstream end of the outer barrel includes an upstream lip interfacing with a downstream lip of an outer wall of the turbine outlet, forming a lap joint. The outer barrel includes a plurality of axial segments disposed between the upstream end of the outer barrel and the outer aft plate, and the axial segments. The inner barrel includes a plurality of axial segments disposed between an upstream end of the inner barrel and the seal interface. The seal interface includes a groove configured to receive the inner aft plate. The poles are spaced about the turbine axis and couple an end of the outer aft plate to an end of the inner aft plate.

System and method for turbine diffuser

A method includes inserting axially a radially interior surface of an aft plate assembly into a circumferential groove of an inner barrel of a diffuser section of a gas turbine, where the aft plate assembly is inserted into a first circumferential orientation relative to the circumferential groove, and the circumferential groove is disposed on a radially exterior surface of the inner barrel. The method includes rotating the aft plate assembly circumferentially within the circumferential groove from the first circumferential orientation to a second circumferential orientation, where the inner barrel is configured to axially retain the aft plate assembly when the aft plate assembly is disposed in the second circumferential orientation.
