This injection, in conjunction with the swirl generated in the swirl space of the combustion air-fuel gas flow to a good mixing of the fuel or premixed gas with the combustion air. Good mixing in such premix burners is the prerequisite for low NO x values during the combustion process.
  • EP 0 918 191 A1 provides for improving the degree of mixing between Fuel and air in the flow direction through the combustion air inlet openings recalculated injection of fuel before, causing it to partial mixing between fuel and combustion air comes before this in the other Inlet of the swirl generator.
  • the training of a to ensure stable flame inside the combustion chamber need extensive and structurally complicated flow-related measures be taken within the burner structure. It also shows that in particular the performance of a burner with regard to flame stability, Emission values and the occurrence of thermoacoustic pulsations in burners for the operation of gas turbine plants of medium and smaller capacities greater instabilities than in the case of burners that are powerful Gas turbine plants are designed.
  • the invention is based on the object, a burner of the aforementioned Art, in particular according to the preamble of claim 1, so to design, that the operating behavior of the burner in the largest possible operating range should be stable, i. the burner should be independent of the current load have the most consistent combustion stability. Moreover, the Burner also with different fuel types or qualities and can be operated stably, especially at lower burner power.
  • the Measures according to the invention should be simple and inexpensive to implement and, moreover, the possibility of retrofitting existing ones Allow burners. Within the above required large operating range the burner should have a minimized pollutant emission as well as a ensure maximum efficiency while forming a stable flame.
  • the inventively constructed burner according to the features of the preamble of claim 1 is characterized by the combination of two measures. So the burner has at least a second fuel supply with at least a second group of substantially in the direction of the burner axis arranged fuel outlet openings for a second Premix fuel quantity, which is independent of the first fuel supply with Fuel is acted upon. In this way it is possible the Fuel supply together with the combustion air supply in the conical swirl space in at least two separate spatial areas along the Adjust burner axis within the swirl space individually and thereby in Dependence of the current burner load on individual fuel-air mixtures within the swirl space.
  • a burner lance projects along a burner axis from the side of the burner Swirl space with the smallest swirl space cross section into the swirl space and has at least one fuel outlet opening within the burner lance, through the fuel, preferably liquid fuel, along the burner axis can be carried out.
  • the burner lance preferably over at least 50% of the axial extent of the swirl space protrudes into this, on the one hand due to their preferably round outer contour which is fluid dynamics forming swirl flow within the swirl space stabilize, which ultimately also the flame front within the combustion chamber is stabilized, on the other hand, which allows preferably in the burner longitudinal axis oriented fuel outlet within the burner lance an additional Discharge of fuel into the swirl space, which coincides with the over the tangential Combustion air inlet openings along the swirl generator introduced Combustion air mixed and for the stable formation of a downstream in the Combustion chamber forming flame front contributes.
  • the advantage of the inventively designed burner is in the multi-stage Fuel feed into the swirl chamber to see what the burner behavior in Depending on the burner load can be set very finely dosed.
  • the burner lance within the swirl space which is a kind Flow body or Umströmungsisson for the longitudinal to the burner axis represents within the swirl space forming fuel-air mixture, the Extent of combustion usually occurring thermoacoustic pulsations significantly reduced.
  • the inventive integration of the burner lance in at least one Double stepped premix burner is a burner operation for each type of Fuel possible. So allows the provided within the swirl space Burner lance the discharge of liquid fuel, preferably axially in Direction of the burner axis.
