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.
- the pressure atomizer nozzle has a nozzle body 1, which consists of an outer tube 2 and an inner tube 3 and downstream of a nozzle head 4 is completed (Fig. 1, Fig. 2).
- a nozzle body 1 In the inner tube 3 is a first feed channel 5 and between the outer tube 2 and the inner tube 3, a second feed channel 6 for formed at least one liquid fuel 7.
- Is upstream of the nozzle head 4 between the inner tube 3 and the outer tube 2 is used for stabilization Spacer 8 arranged.
- the nozzle head 4 takes four equally large turbulence and / or swirl chambers 9, 10, 11, 12.
- the turbulence and / or Swirl chambers 9, 10, 11, 12 under appropriate operating conditions also have a different size (not shown), but on it It is important to ensure that there is always a symmetrical injection.
- Both the turbulence and / or swirl chambers 9, 10, 11, 12 and the nozzle body 1 each have a central axis 9 ', 10', 11 ', 12', 13, the central axes 9 ', 10', 11 ', 12' of the turbulence and / or swirl chambers 9, 10, 11, 12 both in radial as well as in the tangential direction obliquely to the central axis 13 of the nozzle body 1 are arranged.
- An imaginary plane cuts through the central axis 13 of the nozzle body 1, the imaginary planes through the central axes 9 ', 10 ', 11', 12 'of the turbulence and / or swirl chambers 9, 10, 11, 12 inside the Nozzle head 4 both in a radial and in a tangential angle (Fig. 3).
- the location of the turbulence and / or swirl chambers 9, 10, 11, 12 inside of the nozzle head 4 is also in FIGS. 4 and 5 corresponding to that in FIG. 2 shown cuts shown.
- the central axes 9 ', 10', 11 ', 12' of the turbulence and / or Swirl chambers 9, 10, 11, 12 therefore only offset parallel to the central axis 13 of the nozzle body 1 may be arranged.
- Each of the turbulence and / or swirl chambers 9, 10, 11, 12 is by means of a sealing cover 14 to the first feed channel 5 completed.
- two turbulence channels 15 are arranged, which the respective turbulence and / or swirl chamber 9, 10, 11, 12 with the first Connect feed channel 5.
- the turbulence and / or swirl chambers 9, 10, 11, 12 each via a swirl duct 16 with the second feed duct 6 (FIG. 1, Fig. 2) and each connected to an outer space 18 via an outlet opening 17 (Fig. 3, Fig. 6).
- the nozzle body 1 thus has four outlet openings 17, which each only let through a quarter of the total fuel mass flow. For this purpose, they are designed to be smaller than one that takes up the entire mass flow Single hole nozzle and produce at similar liquid fuel pressures smaller droplets.
- the nozzle head 4 In its downstream area, the nozzle head 4 is hemispherical, each outlet opening 17 into a in the hemispherical contour of the nozzle head 4 introduced recess 19 opens and each recess 19th arranged at right angles to the outlet opening 17 each opening into it is.
- any other streamlined design of the downstream is Area of the nozzle head 4 suitable, for example an elliptical shape.
- a first plenum 20 is formed upstream of the closure cover 14, into which the first feed channel 5 opens.
- the first plenum 20 has a larger one Cross-section than the feed channel 5 which acts on it second feed channel 6 and the swirl channels 16 connected to it is a second, circumferential plenum 21 is formed.
- the cross sections of the two plenums 20, 21 are designed to be larger than the sum of the cross sections of those to which they are subjected Turbulence generator channels 15 or swirl channels 16. This is a more compact one Nozzle body 1 realized, which consists of four partial nozzles, each with a turbulence as well as a swirl stage, with a common geometry and with a uniform Diameter exists.
- the liquid fuel 7 is supplied to the nozzle body 1 in a manner known per se Way over lines not shown, such as in EP 0 794 383 A2 shown and described.
- the liquid fuel 7 passes through the first Feed channel 5 into the first plenum 20. From there it is through the turbulence channels 15 the cap 14 as a turbulent flow in the respective turbulence and / or swirl chamber 9, 10, 11, 12 initiated. Because of the compared to the first feed channel 5 enlarged cross section of the first plenum 20 a relatively uniform application of liquid to the turbulence and / or swirl chambers 9, 10, 11, 12 reached.
- the injection is then carried out of liquid fuel 7 into the outside space 18, via the outlet openings 17 of the turbulence and / or swirl chambers 9, 10, 11, 12 Turbulence and / or swirl chambers 9, 10, 11, 12 four fuel sprays of the same size 37 with an improved droplet distribution. Because of the right angle injection of the liquid fuel 7 into the respective recess 19 the outside space 18 circular fuel sprays 37 are formed, what fuel distribution further improved.
- the Arrangement of the turbulence channels 15 in the outer region of the cover 14, i.e. near the side walls of the turbulence and / or swirl chambers 9, 10, 11, 12 contribute to the fact that the liquid fuel full cone spray, not shown forms evenly and thus the distribution of the fuel droplets is further improved.
- the nozzle body 1 is also included connected to a premix burner 22 that the outer space 18 of the nozzle body 1 is at the same time an interior 18 'of the premix burner 22 (FIG. 7).
- the Premix burner 22 is a cone-shaped structure and essentially consists from four superimposed hollow partial cone bodies 23, 24, 25, 26 with one constant cone half angle ⁇ to the burner axis in the direction of flow 27. Im narrowest cross section of the hollow cone-shaped body formed by the partial cone bodies 23, 24, 25, 26 Interior 18 'of the premix burner 22 is the nozzle body 1 arranged.
- the nozzle body 1 has four turbulence and / or Swirl chambers 9, 10, 11, 12 each with an outlet opening 17.
- the partial cone bodies 23, 24, 25, 26 each have an axis of longitudinal symmetry 23 ', 24', 25 ', 26'. The latter run radially offset from one another, so that four flow opposite, tangential air inlet slots 28 for a combustion air mass flow 29 are formed (Fig. 8).
- the Partial cone bodies 23, 24, 25, 26 along the air inlet slots 28 each have a feed line 30, which has longitudinal openings 31 for supplying a gaseous fuel 32 are provided in the interior 18 'of the premix burner 22 (FIG. 7). If necessary, this fuel 32 becomes through the tangential air inlet slots 28 admixed combustion air mass flow 29 introduced into the interior 18 '.
- a mixed operation of the premix burner 22 via the pressure atomizing nozzle and the feed lines 30 is possible.
- each of the four outlet openings 17 of the turbulence and / or swirl chambers 9, 10, 11, 12 is on one of the trailing areas 33, 34, 35, 36 of the partial cone bodies 23, 24, 25, 26 aligned.
- the combustion air mass flow 29 and thus at partial load also reduces its momentum, which necessitates a lower fuel mass flow, a lower spray impulse and therefore smaller fuel droplets causes. Therefore, the respective swirl stage of the pressure atomizing nozzles in this operating state the gas turbine is subjected to a greater load than the turbulence stage.
- An increasing swirl ratio gradually and automatically reduces the mass flow of liquid fuel 7. Because the swirl stage also has a lower Mass flow realized as the turbulence stage, the amount of fuel drops of liquid fuel 7 accordingly. About an increase in droplet size and thus the impact of the fuel droplets on the inner walls 38 of the burner to prevent the transition from the turbulence stage towards the swirl stage.
- the gas turbine load decreases, i.e. with further decreasing Influence of the combustion air mass flow 29 through the transition to one full swirl operation, further reducing the droplet size of the Liquid fuel 7 reached.
- the premix burner can also, according to EP 0 704 657 A2 consist of a swirl generator and a downstream mixing tube, the swirl generator being essentially the premix burner described above 22 corresponds or also a solution for double cone burners i.e. can be realized for a premix burner with two partial cone bodies (not shown).
- the premix burner cannot be conical and / or consist of a number of circularly arranged blades (likewise not shown).
