A transition duct system having a rugged connection at the intersection between adjacent converging transition ducts extending between the combustor and the turbine assembly within a gas turbine engine
A transition duct system having a rugged connection at the intersection between adjacent converging transition ducts extending between the combustor and the turbine assembly within a gas turbine engine
A transition duct system (110) for routing a combustion exhaust gas flow from a combustor (112) to the first stage (114) of a turbine section (116) in a combustion turbine engine (118) is disclosed, whereby the system (110) imparts a circumferential vector to the combustion exhaust gases expelled from the system (110), thereby negating the need for a conventional row one vane assembly. The transition duct system (110) may include a robust converging flow joint between adjacent transition ducts (122, 124) within the system (110) such that adjacent transition sections (116) may be adjoined to each other via an intersection (126) forming a linear edge (128) which provides for a strong robust intersection (126) between the adjacent transition sections (116). In at least one embodiment, the linear edge (128) at the intersection (126) may be within 10 degrees of being orthogonal to an inner edge (130) of the transition sections (116) at the intersection (126).
