Abstract
A burner system with staged fuel injection includes a burner with a swirl generator ( ) 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 ( ) 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 ( ) for measuring the pulsations and emissions of the combustion, as well as a control device ( ) that controls the two stages ( ) 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.
