Definitions

  • the invention relates to a two-stage pressure atomizing nozzle according to the preamble of claim 1, which, for example, in the premix burners of a gas turbine plant is used.
  • EP 0 794 383 A2 has a two-stage pressure atomizing nozzle, which one Adjustment of the drop spray with regard to the atomization quality, the drop size and the spray angle to the respective load conditions.
  • the nozzle is characterized by a simple, little space requirement Type out.
  • the pressure atomizer nozzle has at least a first channel for the liquid to be atomized, through which the latter can be fed under pressure. Opens into the turbulence and / or swirl chamber at least one further channel for part of the liquid to be atomized or for a second liquid to be atomized, through which said part of the Liquid or the second liquid can be supplied under pressure and with swirl.
  • swirl nozzles In order to inject the fuel droplets into the outer areas of the To realize the burner, swirl nozzles with large jet angles are often used. Such a swirl nozzle injects in the right direction, but it does the small droplets it produces do not have sufficient momentum to the liquid fuel before it is vaporized or before it is influenced by to transport the air to the outer areas of the burner. Because of the large scatter in the initial distribution of droplet sizes on the other hand, large drops get into the outer areas. These drops However, they are not vaporized and can ultimately reach the burner walls hit, with the danger of the flame striking back in the wall Flow regions.
  • the invention tries to avoid all of these disadvantages. You have the task based on a two-stage pressure atomizing nozzle for at least one to be atomized To create fluid with which an improved fluid distribution in the outside of the pressure atomizer nozzle, in particular a better fuel distribution in a premix burner.
  • the pressure atomizing nozzle an the outside and the inner tube has a nozzle head connecting one another downstream and in Nozzle head arranged at least two separate turbulence and / or swirl chambers are.
  • Each of these turbulence and / or swirl chambers is over at least one Swirl duct with the second feed duct, via at least one turbulence generator duct with the first feed channel and via an outlet opening to the outside space of the nozzle body connected.
  • the Outlet openings each of which is only a part of the total liquid mass flow can be made smaller than that of a nozzle is possible with only one outlet opening.
  • smaller outlet openings in the swirl stage create a substantial one thinner liquid film, resulting in smaller droplets with less in the swirl stage Depth of entry are produced. That is why the range of uses of Pressure atomizer nozzle advantageously also shifted in the direction of part-load operation.
  • the nozzle body and the turbulence and / or swirl chambers each have one Central axis.
  • the central axes of the turbulence and / or swirl chambers are radial offset to the central axis of the nozzle body, preferably both radially and arranged obliquely to the central axis of the nozzle body in the tangential direction. In general, this can result in better liquid distribution over large areas Cross-sectional areas can be achieved.
  • the pressure atomizer nozzle the radial displacement and the inclination of the central axes of the turbulence and / or swirl chambers to the central axis of the nozzle body to the desired Adjusted spraying directions of the sprays being formed.
  • a sealing cover which receives the at least one turbulence generator channel arranged.
  • the first feed channel opens into a first, upstream of the cover trained plenum, while between the second feed channel and the a second, rotating plenum is formed.
  • all turbulence and / or swirl chambers can advantageously be used with only one first and only a second feed line can be provided, which is a very compact trained nozzle body allows.
  • the first one is particularly advantageous Plenum has a larger cross-section than the feed channel acting on it, whereby a more uniform fluid loading of the turbulence and / or Swirl chambers is reached.
  • the cross sections have the same advantage of the two plenums also larger than the sum of the cross sections of the Turbulence generator or swirl channels acted upon them.
  • the nozzle head is hemispherical in its downstream area educated. This can lead to the emergence of a so-called dead water area in the wake of the nozzle and thus possibly connected with droplet deposits Flow separations can be counteracted.
  • this hemispherical Recesses are made in the contour of the nozzle head, with each outlet opening opens into one of the recesses and each recess is rectangular is arranged to the outlet opening into it. Because of this design of the outlet area can be the liquid distribution in the exterior of the nozzle body can be further improved.
  • the nozzle body is with a premix burner connected that its exterior space is simultaneously an interior space of the Premix burner is.
  • the premix burner consists essentially of four in Hollow partial cone bodies positioned one on top of the other with a constant cone half angle ⁇ in the direction of flow.
  • the longitudinal symmetry axes the partial cone body are radially offset from one another, so that four flow opposite, tangential air inlet slots for a combustion air flow are trained.
  • the nozzle body is in through the tapered body formed, hollow cone-shaped interior of the premix burner. Downstream of each partial cone body is a trailing area of the partial cone body educated.
  • the fuel mass flow is over the turbulence and / or swirl chambers are divided into four equal partial flows. Since the Turbulence and / or swirl chambers each have a smaller outlet opening, than that with only one turbulence and / or swirl chamber with a single one Outlet opening can be realized, a thinner fuel spray can thus be generated become. This results in smaller droplets of fuel, which are smaller Penetration depth into the burner interior and much faster, i.e. Vaporize before hitting the inner wall of the partial cone body.
  • Such a pressure atomizing nozzle or the burner equipped with it can by simply regulating the fuel supply, i.e. by switching from turbulence operation to the swirl operation or mixed operation to the full load or part load requirements be adjusted. Because of the versatile switch options between swirl-enhanced and turbulence-enhanced spray mist is the solution applicable to most machine and performance conditions.
