摘要： 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.

摘要： A sensor 11 detects the acoustic pressure at a first location in a combustion chamber 7 of a test rig 1 and produces an input signal which is a function of the acoustic pressure. A controller 13 receives the input signal and produces an output signal which is a function of the input signal. An acoustic actuator (16-18) receives the output signal and introduces into the combustion chamber 7 at a second location an acoustic pressure which is a function of the output signal. The acoustic actuator may comprise a fuel injector 18 or a loudspeaker. By using an appropriate control algorithm, acoustic boundary conditions corresponding to a particular gas turbine combustion chamber may be produced, at least in a certain frequency range.

摘要： A premix burner is disclosed, with a swirl generator which delimits a conical swirl space and provides at least two conical part shells which are arranged, offset to one another, along a burner axis, mutually enclose in each case air inlet slits running longitudinally with respect to the burner axis and have in combination a conically widening premix burner outer contour having a maximum outside diameter which narrows axially into a region with a minimum outside diameter. At least one conical part shell provides, in the region between the maximum and the minimum outside diameter, a reception unit which deviates from the conically widening premix burner outer contour and locally elevates the premix burner outer contour radially outward and which has a maximum radial extent which is dimensioned smaller than half the maximum outside diameter of the premix burner outer contour. Within the reception unit, at least one hollow duct is provided, with at least one duct orifice facing away from the swirl space and with a duct longitudinal extent which runs essentially parallel to the burner axis.

摘要： A method and a device are described for the controlled damping of combustion-driven oscillations in a turbomachine with a burner system providing at least one burner, into which is introduced, via at least one burner nozzle arranged centrally in the burner, fuel which is intermixed with combustion inflow air flowing into the burner, to form a fuel/air mixture which is ignited in a combustion chamber following the burner system. The invention is distinguished in that the fuel nozzle is designed in the form of a burner lance, at the lance end of which fuel discharge into the burner takes place, and in that the burner lance projects into the burner in the amount of at least one third of the axial burner length.
