Abstract
A combination of pre-mixing burners and catalytic supported and preferably gas-operated burners is disposed in a combustion chamber for gas turbines, wherein the main combustion is performed by the pre-mixing burners. The pre-mixing burners and the catalytic burners are embodied to be interchangeable. The catalytic burners are provided with an exhaust gas return, wherein the exhaust gas is preferably taken from the combustion chamber. The inlet for the combustion air for the catalytic burners is embodied as a jet pump, which aspirates the exhaust gas from the combustion chamber.
