Abstract
A plurality of flow channels permit a controlled flow of compressed air to flow therein in contact with the flange of a gas turbine combustor transition piece to reduce the operational temperature of the flange and to thereby reduce stress creep distortion of the flange. The flow channels may be disposed in a surface of the flange facing a seal member or in a surface of the seal member facing the flange. In one embodiment, a longitudinal slot in the flange permits the entry of a sealing flange or seal plate. The flow channels may be disposed in the surface of the slot or in the surface of the flange or seal plate. In another embodiment of the invention, the seal member embraces the exterior of the flange and the flow channels may be disposed in either of the facing surfaces.
