Abstract

A burner system with staged fuel injection includes a burner with a swirl generator (1) for a combustion air stream and device(s) for introducing fuel into the combustion air stream, wherein the fuel introducing devices include at least two separate fuel supply elements (4a, 4b) with groups of fuel outlet openings for corresponding premix fuel amounts, wherein a first group is arranged downstream from a second group. The burner system furthermore includes measurement value probes (8, 9) for measuring the pulsations and emissions of the combustion, as well as a control device (10) that controls the two stages (4a, 4b) for introducing fuel dependent on the measured measuring values. The burner system permits optimized operation of the system even under changing operating and environmental conditions.
