Claim Text:
1. A combustor transition system adapted to guide combustion gases in a hot gas flow path extending between a gas turbine combustion chamber and a first stage of a turbine, the combustor transition system comprising: a plurality of ducts comprising a first duct and a second duct, each of the ducts having an inlet at an upstream end adapted for connection to the combustion chamber and an outlet at a downstream end adapted for connection to the first stage of the turbine, wherein the downstream end comprises an outer wall, an inner wall, a first side wall, and a second side wall; the first side wall of the first duct having a first side wall extension that extends in a downstream direction beyond an outlet of a first combustor transition; the second side wall of the second duct having a second side wall extension that extends in the downstream direction beyond an outlet of a second combustor transition; the first side wall extension being split from the second side wall extension by a split line; and the second side wall extension extending in the downstream direction beyond the first side wall extension, the second side wall extension being longer than the first side wall extension, a portion of the second side wall extension extending beyond the first side wall extension having a U-shaped cross section that is configured to separate a hot gas side from a cooling side.
