Abstract
A gas-turbine combustion chamber has a cooling-air supply device delivering cooling air to a combustion chamber wallto be cooled. The cooling-air supply device includes at least one air-supply ductwhich, in respect of its flow axis, is arranged vertically to the combustion chamber wall, with the air-supply ductbeing flow-connected to at least one cooling duct. The air-supply ductforms a throttle and has a smaller diameter than the cooling duct. The cooling ductissues at a shallow angle, relative to its flow axis, to the surface of the combustion chamber wallin a recessof the combustion chamber wall, with the cooling ductbeing designed to impart a swirl to the air flowing through it.
