Abstract (en)
[origin: EP1431662A1] Closed cooled combustion chamber for a turbine comprises an inner wall and an outer wall (1) defining the combustion chamber, an intermediate chamber arranged between the inner and outer wall and containing a cooling fluid, a cooling fluid feed leading into the intermediate chamber, and a cooling fluid outlet for removing the cooling fluid from the intermediate chamber. The cooling fluid outlet has channel-like diverting structures (21, 22) running along the axial orientation of the combustion chamber and interrupted by inlet structures (6) of the cooling fluid feed arranged between the diverting structures. Preferred Features: Circular diverting openings (7) formed in the outer wall lead into the diverting channels.
