GAS TURBINE COMBUSTION CHAMBER

Combustion chamber (1) for a gas turbine, with a flame tube (3) of the co mbustion chamber (1) having, in the flow direction, a mixing zone (15) for m ixing a fuel with air to form a fuel/air mixture, as well as a primary combu stion zone (17) and a post-primary combustion zone (18). At least one openin g (5, 6) is in each case provided in the area of the mixing zone (15) and in the area of the post-primary combustion zone (18), in order to pass compres sed air into the flame tube (3). The compressed air that is supplied is inte nded to cool the flame tube (3), and parts of it are then passed via the ope nings (5, 6) in the area of the mixing zone (15) and in the area of the post -primary combustion zone (18) into the mixing zone (15) and into the post-pr imary combustion zone (18).
