Abstract

A transition duct exit frame (10) for supporting a transition duct (12) extending downstream from a combustor (14) to a turbine assembly (16) in a gas turbine engine (18) and including one or more transition duct exit frame inserts (20) configured to reduce thermal distortion created during operation of the gas turbine engine (18) is disclosed. The transition duct exit frame (10) is formed from one or more transition duct exit frame bodies (22). The transition duct exit frame body (22) is formed from a first material having a first coefficient of thermal expansion. The transition duct exit frame insert (20) forms at least a portion of the transition duct exit frame body. The transition duct exit frame insert (20) is formed from a second material (26) having a second coefficient of thermal expansion that is different than the first coefficient of thermal expansion of the first material (24) to reduce distortion within the transition duct exit frame body (22) during operation of the gas turbine engine (18).

Description

technical field [0001] The present invention relates generally to combustion turbine engines, and more particularly to transition piece ducts for conveying combustor exhaust gas flow from the combustor to a turbine assembly of the combustion turbine engine. Background technique [0002] Typically, a gas turbine engine includes a compressor for compressing air, a combustor for mixing the compressed air with fuel and igniting the mixture, and a turbine blade assembly for generating power. A transition piece duct extends between the combustor and the turbine bucket assembly to direct combustor gases through the turbine bucket assembly to impart rotational motion to a rotor of the turbine bucket assembly. Traditional transition piece ducts are typically formed from plenums that require support at the outlet from a more rigid mounting support structure that is welded to the plenum. A rigid support structure is used to attach the transition piece assembly to the turbine inlet. T...
