Claims
- 1. A steam-cooled gas turbine combustor arranged between a combustion nozzle and a tailpipe, said combustor having a combustor wall which is exposed on an interior side thereof to combustion gases, and in which high-pressure steam is used as a cooling medium, said combustor wall comprising:
- a plurality of cooling channels for cooling steam extending parallel to each other, sealed by an exterior wall panel and a heat-resistant plate, which are assembled together so that said cooling steam flows in one direction through said parallel cooling channels;
- a supply manifold for supplying said cooling steam into said cooling channels, which is provided on an inlet end of said parallel cooling channels; and
- a recovery manifold for recovering said cooling steam from said cooling channels, which is provided on an outlet end of said parallel cooling channels.
- 2. A steam-cooled gas turbine combustor according to claim 1, wherein said supply manifold is located at a gas inlet of a combustion chamber adjacent the combustion nozzle, and said recovery manifold is located at a gas outlet of said combustion chamber adjacent the tailpipe.
- 3. A gas turbine combustor according to claim 1, wherein said exterior wall panel and said heat-resistant plate are assembled by soldering.
- 4. A gas turbine combustor according to claim 1, wherein said parallel cooling channels are formed by grooves in the exterior of the combustor wall panel covered by said heat-resistant plate.
