Definitions

  • FIG. 5 is used at the same time as FIG. 4. Furthermore, in order not to make this Fig. 4 unnecessarily confusing, are the after the Figure 3 schematically shown guide plates 121a, 121b only hinted at been. The following is the description of FIG. 4 as needed referred to the figures mentioned.
  • the two conical partial bodies 101, 102 each have one cylindrical initial part 101a, 102a, which also, analogous to the conical partial bodies 101, 102, run offset from one another, so that the tangential air inlet slots 119, 120 available over the entire length of the swirl generator 100 are.
  • a nozzle 103 is preferred in the area of the cylindrical starting part for a liquid fuel 112, the injection 104 approximately with the narrowest cross section of that formed by the tapered partial body 101, 102 Cone cavity 114 coincides.
  • the injection capacity and the type this nozzle 103 depends on the given parameters of the respective Brenners.
  • the swirl generator 100 can be purely conical, that is, without cylindrical starting parts 101a, 102a.
  • FIG. 7 differs from FIG. 6 in that the partial bodies 140 here 141, 142, 143 have a blade profile shape which is used to provide a certain Flow is provided. Otherwise, the mode of operation of the swirl generator stayed the same.
  • the admixture of fuel 116 in the combustion air flow 115 happens from inside the blade profiles, i.e. the fuel line 108 is now integrated in the individual blades.
  • the transition geometry is body for a swirl generator 100 with four parts, accordingly 6 or 5, built. Accordingly, the transition geometry as a natural extension of the upstream partial bodies, four transition channels 201 on, whereby the conical quarter area of said partial body is extended until the wall of the tube 20 resp. of the mixing tube 220 cuts.
  • the same considerations also apply if the swirl generator comes from another Principle, as that described in Fig. 4, is constructed.
  • the down area of the individual transition channels 201 running in the direction of flow has a spiral shape in the flow direction, which has a describes crescent-shaped course, corresponding to the fact that present the flow cross section of the transition piece 200 in the flow direction flared.
