Abstract
In order to provide an annular combustion chamber () which can be heated without thermal distortion, expands without distortion, and is reliably closed, and for repairs can be opened and permanently closed again and can be reconditioned, the inner and/or outer shell () of an annular combustion chamber () is produced from a rotationally symmetrical sheet metal. For assembly, the shells are cut open along a split line (), and the lower half of the inner and of the outer shell () is introduced into the lower casing half of a gas turbine. After the insertion of the rotor, the two upper shell halves can likewise be inserted and be connected to the lower halves by welding. In order to improve the service life of the split line weld seam (), film cooling of the weld seam is routed by an indentation. This may be implemented, for example, by welded-in split line elements () which are also suitable for retrofitting.
