Abstract
Provided is a transition piece including a first flow path group formed by arraying a plurality of in-wall flow paths that extend inside a plate material forming the transition piece and a second flow path group that is positioned on a side closer to a combustor liner than the first flow path group is. Each in-wall flow path in the first flow path group and the second flow path group has an inlet that is located at one end section in a flow direction of a combustion gas and that faces a compressed air main flow path, and an outlet that is located at the other end section in the flow direction of the combustion gas and that faces a combustion gas flow path. An installation area of the first flow path group and an installation area of the second flow path group partially overlap in the flow direction of the combustion gas by a predetermined overlap amount, and the overlap amount is set large for a portion where a shape change of the transition piece is relatively large, as compared with a portion where the shape change of the transition piece is relatively small.
