Abstract: A burner has a housing on which a combustion tube is arranged, wherein the combustion tube has an opening at the end averted from the housing, wherein a mixing element is provided in the combustion tube, and the space between the mixing element and the opening forms a combustion chamber, wherein the housing has at least two mutually separate channels which open out in the mixing element, wherein gases flow through the channels and the mixing element, and mixing of the gases takes place for the first time in a combustion chamber, wherein the mixing element is produced in an additive manufacturing process and has at least two separate intermediate channels which branch in the direction of the combustion chamber in a flow direction.

Abstract: A fuel nozzle system is made available, which is arranged essentially in circular manner and is set up in such a manner that it produces a homogeneous leaner mixture on at least one outer ring and a homogeneous richer mixture on at least one inner ring, in particular a fuel/oxidizer mixture.
