Embodiment Construction

[0037] figure 1 A combustion chamber 1 of a gas turbine 24 is shown, which comprises a hermetically cooled burner insert 3 for feeding and / or igniting a flammable mixture and an outlet 4 which can be installed in the inlet 2 of the combustion chamber 1 to be cooled in a closed manner. The burner insert 3 can be fastened via a flat base plate 5 which can be fastened in the region of the inlet opening 2 . The bottom plate 5 simultaneously forms part of the inner wall 6 of the combustion chamber 1 with its side faces 55 . The outwardly facing side 7 of the bottom plate 5 forms two channels 9 with a flat molded part 8 mounted on it, which communicate flow-wise on the input side with a coolant source not shown in detail in the figure, and on the output side communicates with a channel system of the burner insert 3 ( image 3 ).

[0038] The shaped part 8 , which is designed here as a sheet metal part and also called a baffle cooling plate, together with the groove 34 formed in t...

Abstract

The invention relates to a combustion chamber for a gas turbine having at least one closed-circuit-cooled burner insert which can be disposed in an inlet opening of the combustion chamber for the purpose of feeding and / or igniting a combustible gas / air mixture, and having an outlet opening. The object of the present invention is therefore to create an arrangement enabling simplified manufacture and assembly to be achieved. To achieve this object there is proposed according to the invention a combustion chamber for a gas turbine having at least one closed-circuit-cooled burner insert which can be disposed in an inlet opening of the combustion chamber for the purpose of feeding and / or igniting a combustible gas / air mixture, and having an outlet opening, at least one hot-gas-path component, specifically a component of an inner wall of the combustion chamber, forming on its outer side opposite the hot-gas-path side (55), in conjunction with a planar shaped element disposed thereabove, at least one channel which is fluidically connected to a coolant source on the feed side and to a channel arrangement of the burner insert on the discharge side.

Description

technical field [0001] The invention relates to a combustion chamber of a gas turbine comprising at least one hermetically cooled burner insert which can be accommodated in the inlet of the combustion chamber and an outlet for feeding and / or igniting a combustible mixture gas. The invention also relates to a burner insert mounted on such a combustion chamber and to a gas turbine with such a combustion chamber. Background technique [0002] In addition to their use in aircraft for propulsion, gas turbines are especially widely used in power generation equipment. In this, a flammable mixture is combusted in a combustion chamber, and the energy released through an exothermic reaction causes expansion and / or pressure increase. The gas thus produced is supplied downstream to the flow channel of a turbine in order to convert the energy of the gas into mechanical energy, in particular rotational kinetic energy. The rotational kinetic energy of the machine thus obtained can be us...
