Combustion chamber for a gas turbine

A burner insert adapted for disposition in an inlet opening of a combustion chamber comprising:

• a first area connected to an outer wall of the combustion chamber;
• and
• a second area detachably connected to the first connected area and facing the combustion chamber, wherein the second area is connected to an inlet opening of the combustion chamber via the baseplate,
• wherein the combustion chamber comprises:
• a closed-circuit-cooled burner insert which can be disposed in the inlet opening of the combustion chamber for the purpose of feeding and/or igniting a combustible gas/air mixture;
• an outlet opening;
• a hot-gas-path component;
• and
• a sealing element that can be disposed between a mounting flange and a mounting area of the inlet opening;
• and
• a planar shaped element disposed above and connected to the hot-gas-path component,
• wherein the hot-gas-path component and the planar shaped element collectively form a channel which is fluidically connected to a coolant source on a first side and to a closed circuit cooling channel system of the burner insert on a second side.

A gas turbine with a blade arrangement comprising:

• a flow path with rotor blades disposed on a rotor;
• a plurality of fixed stationary vanes;
• and
• a combustion chamber disposed upstream of the blade arrangement in the flow direction of a gas flow,
• wherein the combustion chamber comprises:
• a 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;
• an outlet opening;
• a hot-gas-path component;
• a sealing element that can be disposed between a mounting flange and a mounting area of the inlet opening:
• and
• a planar shaped element disposed above and connected to the hot-gas-path component,
• wherein the hot-gas-path component and the planar shaped element collectively form a channel which is fluidically connected to a coolant source on a first side and to a closed circuit cooling channel system of the burner insert on a second side.
