A turbine or turbine system includes a compressor, a combustor, a turbine section, a diffuser with a parting line between two components, and a seal along the parting line. The seal includes a protrusion, a recess, and a flexible portion between the protrusion and the recess. The flexible portion has a bent cross-section perpendicular to the parting line. An outer surface of the bent cross-section contacts an inner surface of the recess. An inner surface of the bent cross-section contacts an outer surface of the protrusion. Sealing a parting line between two parts of a diffuser in a gas turbine system includes disposing a flexible portion between a protrusion and a recess of the two parts, contacting an outer surface of the bent cross-section with an inner surface of the recess, contacting an inner surface of the bent cross-section with an outer surface of the protrusion, and pressurizing the diffuser.

Apparatus and method for sealing turbine assembly

An exhaust gas diffuser () including: a radially-outer peripheral casing (); a hub () located within said radially-outer peripheral casing and coaxial with a center axis () of the casing; main struts () located at circumferentially-spaced locations about the hub and extending radially-outwardly to the radially outer peripheral casing; and small struts () located at circumferentially-spaced locations between the main struts; wherein the main struts and small struts have substantially parallel longitudinal chord lines and each of the small struts have a cross-sectional area smaller than a cross-sectional area of the main struts.
