Abstract (en)

[origin: EP1865259A2] Fitted in a gas turbine combustor casing (2,3), combustor segments form a combustor wall (10) and are each impinged by cooling air with a film cooling via axial and/or radial cooling holes (16,17) fitted with a clearance from each other in an axial direction. In this area there are absorbing openings (19a) for introducing cooling air.
