Abstract: This application provides exhaust frame cooling systems for use with gas turbine engines. Example systems may include an exhaust system for use with a gas turbine engine. The exhaust system may include a strut positioned between an inner barrel and an outer barrel. The strut may include an inner body and an outer body. The exhaust system may include at least one strut hole formed in the inner body, where the at least one strut hole forms a first cooling path for cooling flow in a first direction, a cavity between the inner body and the outer body, where the cavity forms a second cooling path for the cooling flow in a second direction, and a purge outlet to purge the cooling flow at the inner barrel.

Abstract: 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.
