Abstract
In a premixing burner ( ) for a gas turbine or hot-gas generation for the combustion of liquid or gaseous fuel, in which fuel is mixed with combustion air ( ) in a burner interior ( ), is fed to a combustion chamber ( ) and is burnt in this combustion chamber ( ), stabilization in the part-load model is achieved in a simple and efficient way in that means ( ) are provided which make it possible to recirculate hot exhaust gas ( ) out of the combustion chamber ( ) into the burner interior ( ) and to stabilize the flame by means of selfignition processes. The means ( ) are preferably a recirculation line which picks up hot exhaust gas ( ) from the outer backflow zone ( ) and feeds it to the burner interior ( ) in the region of a burner tip ( ) facing away from the combustion chamber ( ), additional fuel (pilot fuel ) being admixed with the exhaust gas ( ) in the recirculation line upstream of the feed to the burner interior ( ).
