Definitions

  • the invention relates to a mixing device for a burner according to the preamble of patent claim 1.
  • a mixing device of this type is known from EP 0777083 B1 known.
  • This known mixing device for a burner in particular for fossil fuels, has a burner tube, a flame tube adjoining the burner tube and a nozzle assembly arranged in the burner rod.
  • the interior of the burner tube is closed against the interior of the flame tube with a cutting disc having a central opening, on which coaxially an air nozzle is arranged, which extends into the flame tube and combustion air from the burner tube leads into the flame tube.
  • the nozzle is held by means of a holder coaxially in the combustion tube and the air nozzle.
  • the blade is axially displaceable in the burner tube to adjustably alter the passage cross-section of recirculation ports through which combustion gases recirculate from the furnace to the flame.
  • the cutting disc is sealed by a substantially cylindrical metallic guide ring against the burner tube, which bears sealingly and displaceably with its outer circumferential surface on the inner wall of the burner tube. Due to the high temperature fluctuations, the guide ring on an axially continuous parting line to avoid material stresses due to heating or cooling. In particular, the guide ring can thereby be easily mounted on the circumference of the cutting disc and create resiliently against the inner wall of the tube.
  • a disadvantage of this parting line is that through the parting line leakage air from the burner tube space can enter the flame tube space, which can lead to local and asymmetrical temperature fluctuations and soot formation on the inside of the flame tube.
  • the object of the invention is therefore to provide a mixing device for a burner, which prevents as reliably as possible that leakage air can flow through the parting line of the guide ring.
  • the burner tube has a retracted edge at the transition to the flame tube.
  • This retracted edge forms a stop for the axially displaceable metallic guide ring, in which the cutting disc is inserted.
  • the retracted edge covers the parting line and prevents air from flowing through the parting line on the cutting disc past into the flame tube.
  • the blade has a pot-shaped bottom with an outer diameter, which faces in the direction of the flame tube.
  • the retracted edge of the burner tube thus has an opening with an inner diameter which is smaller than the inner diameter of the burner tube.
  • the inner diameter of the opening of the retracted edge of the burner tube substantially corresponds to the outer diameter of the cup-shaped bottom of the cutting disc, but is slightly larger, so that a displacement of the cutting disc in the opening is possible.
  • a particularly good seal between the blade and the burner tube is ensured when the blade dips into the opening of the retracted edge of the burner tube.
  • the cutting disc on several air passage openings, which are followed by trachea, which protrude into the flame tube inside.
  • combustion air from the burner tube enters the flame tube through these trachea tubes.
  • This additionally supplied combustion air reduces and minimizes the concentration of the hydrocarbon gases originating from the fossil fuel between the flame and the wall of the flame tube.
  • the corrosion of the flame tube by these hydrocarbon gases, the so-called metal dusting can be significantly reduced and largely avoided.
  • the additional air passage openings increase the air passage cross-section for the combustion air, so that the required combustion air can be brought into the flame tube with a lower blower power.
  • the tracheae serve in particular for noise reduction, since the air can flow laminar through the trachea tubes, and to increase the burner output.
  • the blade has at least three air passage openings, which are preferably offset from one another at the same angular distance, so that the supplied combustion air is evenly distributed and forms a uniform air jacket.
  • the use of three traverted by 120 ° in each case trachea forms a sufficiently closed air jacket.
  • swirl slots can be arranged in the cutting disc. These also allow the supply of additional combustion air, wherein the combustion air flowing through the swirl slots has a twist and surrounds the flame in the flame tube in the form of a cylinder jacket. This combustion air additionally supplied at the outer periphery of the flame increases the oxygen supply at the outer periphery of the flame, thereby improving the combustion in the outer periphery of the flame. As a result, the formation of soot on the outer flame circumference is reduced and a sooting of the inner wall of the flame tube counteracted.
  • the production of the spiral slots is more cost-effective than arranging tracheas on the cutting disc.
  • the swirl slots allow better air distribution around the flame than the trachea.
  • the air nozzle has an outer diameter which tapers from a diameter which is greater than the diameter of the opening of the cutting disc to a diameter which is smaller than the diameter of the opening, and in that the air nozzle of the burner tube side is coaxially immersed in the opening of the cutting disc and is supported with its circumference axially on the cutting disc.
  • the air nozzle therefore protrudes only over a small axial length in the flame tube. This results Only a minimal axial distance between the air outlet of the air nozzle and the cutting disc, which can act as a dead space in the flame tube, in which not completely burned combustion gases cool and can cause soot deposition.
  • the air nozzle can, for example, have a conical, conical or curved jacket, on which the combustion air can flow laminarly, so that an optimal air flow in the air nozzle is ensured. Since the air nozzle is supported with its outer circumference on the cutting disc, on the inside of the air nozzle no steps in the flow path of the combustion air are present, which could cause turbulence. In particular, the air nozzle can be adjusted exactly coaxial with the nozzle in the blade.
  • the holder has a hub which receives and holds the nozzle.
  • the holder is expediently on the burner tube side of the air nozzle to axially seat the air nozzle in the opening of the cutting disc.
  • the holder on supporting elements, which are performed starting from the hub by a respective recess in the peripheral edge of the burner tube end of the air nozzle and burner tube side are attached to the cutting disc.
  • the support elements preferably have shoulders which are supported on the burner tube side at the recesses.
  • the guide ring in its inner circumferential surface on a circumferential inner groove, in which the cutting disc is inserted with its peripheral edge.
  • the cutting disc is reliably held in the sealing guide ring and moved simultaneously with the guide ring axially in the burner tube.
  • the flame tube is detachably mounted on the burner tube to facilitate assembly work.
  • a transistor coil ignition is performed by the cutting disc in the flame tube, which additionally has a circuit arrangement for flame detection.
  • mixing devices for burners have a device for flame detection which is separate from the ignition device, in order to ensure that the flame burns at the desired times or that, in the event of an uncontrolled extinction of the flame, the fault shutdown can be initiated.
  • these devices can be based on determining the brightness in the interior of the flame tube by means of a light tube in conjunction with an optical sensor.
  • this light tube and the optical sensor can be omitted if the transistor coil ignition additionally has a circuit arrangement for flame detection, whereby the mixing device is cheaper.
  • Such a circuit arrangement for flame detection is, for example, from the DE 43 24 863 C2 known.
  • the mixing device according to the invention is used in particular in a blue burner, in particular for liquid fuels.
  • Fig. 1 shows an axial section through a mixing device 10, which has a burner tube 20, fed by the combustion air from a blower, not shown becomes.
  • the burner tube 20 is followed axially by a flame tube 30.
  • the burner tube 20 and the flame tube 30 may have a substantially identical diameter as shown, but it is also possible that the flame tube 30 widens or tapers in diameter with respect to the burner tube 20.
  • the flame tube 30 is connected via not shown connecting elements with the burner tube 20. Between the connecting elements recirculation openings 35 are formed on the outer circumference.
  • a cutting disc 50 is used, which has a cup-shaped bottom 53 which is arranged in the direction of the flame tube 30, so that the pot opens in the direction of the combustion tube 20.
  • the cutting disk 50 is held over an outer circumference 52 in a guide ring 60, which has an inner groove 64 into which the outer circumference 52 of the cutting disk 50 engages.
  • the guide ring 60 has a parting line 62, which is shown in Figures 2 to 4, which makes it possible to put the guide ring 60 on the cutting disc 50 and which also prevents temperature fluctuations in the material of the guide ring 60, which in particular is made of a metal, in particular brass, form.
  • the guide ring 60 abuts against the inner wall of the burner tube 20 and is elastically braced radially on the burner tube 20.
  • the guide ring 60 is axially displaceable and friction-locked in the burner tube 20 in this way.
  • the cutting disc 50 can be adjusted axially in the burner tube 20.
  • the cup-shaped bottom 53 of the cutting disc 50 depending on its axial position in the combustion tube 20, the recirculation openings 35 between the burner tube 20 and the flame tube 30 more or less close, whereby the combustion gases returned to the flame from the combustion chamber via the recirculation openings 35 can be adjusted. It is essential that the cup-shaped bottom 53 has a height such that the recirculation openings 35 are completely closed in any position of the cutting disk 50.
  • a central opening 51 is inserted, in which an air nozzle 70 is inserted.
  • the air nozzle 70 is formed to have an outer diameter at the burner tube end that is larger than the diameter of the opening 51 of the separator disk 50, while having an outer diameter at its flame tube end that is smaller than the diameter of the opening 51 of the separator disk 50.
  • the air nozzle 70 thus has a substantially conical shape, which may also have a curved outer shell or a frustoconical outer shell. By this configuration, the air nozzle 70 dives with its flame tube side end of the burner tube side into the opening 51 of the cutting disc 50 and projects axially slightly above the bottom 53 in the direction of the flame tube 30 from the cutting disc 50.
  • the combustion air supplied via the burner tube 20 thus flows through the air nozzle 70, which has substantially no steps on its inner wall, so that turbulence of the combustion air is avoided and the combustion air is reliably guided to the flame tube end of the air nozzle 70.
  • a nozzle 40 is axially inserted, via which the fossil fuel is supplied.
  • the fuel exhausts via a fuel nozzle 42.
  • two ignition electrodes 57 of a transistor coil ignition are performed, with which the atomized fuel is ignited.
  • the ignition electrodes 57 are angled at its free end such that their free ends are located at a smaller distance than their ends guided by the bottom 53, wherein the free ends are bent substantially in front of the flame tube side opening of the air nozzle 70. Between the two free ends of the ignition electrons 57, the flame is ignited.
  • the fuel nozzle 42 is arranged at a small distance upstream of the flame tube side outlet opening of the air nozzle 70. The fuel nozzle 42 is thus located substantially in the plane of the bottom 53 of the cutting disk 50 behind the flame tube end of the air nozzle 70, so that the resulting flame extends in the flame tube 30 in front of the flame tube end of the air nozzle 70.
  • the cup-shaped bottom 53 is closed except for the opening 51 through which an axial portion of the air nozzle 70 protrudes.
  • air passage openings 54 are additionally arranged in the bottom 53 of the separating disk 50, on each of which a trachea 55 is arranged in the direction of the flame tube 30.
  • the trachea tubes 55 shown in FIG. 3 have a longitudinal axis which runs perpendicular to the bottom 53 of the separating disc 50.
  • four trachea tubes 55 are arranged which are offset from each other at the same angle.
  • combustion air is also on the outer circumference supplied to the front of the flame tube end of the air nozzle 70 resulting flame.
  • FIG. 4 shows a third exemplary embodiment of the bottom 53 of the cutting disk 50, in which, as an alternative to the tracheal tubes 55, swirl slots 56 are embedded in the bottom 53.
  • the swirl slots 56 are offset from each other substantially at the same angular distance and cause combustion air is additionally supplied to the outer periphery of the flame, wherein the swirl slots are formed such that the supplied air has a twist.
  • FIGS. 2 to 4 show, in particular, the parting line 62 of the guide ring 60. If the separating disk 50 according to the embodiments of FIGS. 2 to 4 is inserted into the burner tube 20, as shown in FIG. 1, the guide ring 60 slides on the inner surface of the burner tube 20 , wherein the cup-shaped bottom 53 of the cutting disk 50 points in the direction of the flame tube 30. Through the parting line 52, however, leakage air can pass. To avoid this, the burner tube 20 has a retracted edge 22 at its flame tube end, which forms an opening 24.
  • the inner diameter of the opening 24 corresponds substantially to the outer diameter of the cup-shaped bottom 53 of the cutting disk 50, so that when the cutting disk 50 dips with its cup-shaped bottom 53 in the opening 24, thereby the burner tube 20 is substantially closed against the interior of the flame tube 30.
  • the air thus flows essentially through the air nozzle 70 from the combustion tube 20 into the flame tube 30.
  • the maximum diameter of the cutting disk 50 which is measured in the region of the outer circumference 52 which can be inserted into the inner groove 64 of the guide ring 60 is also measured , almost as large as the inner diameter of the combustion tube 20, so the guide ring 60 rests with its outer surface on the inner wall of the combustion tube 20 and in this way the interior of the burner tube 20 can be completed with respect to the interior of the flame tube.
  • the retracted edge 22 of the burner tube 20 forms a stop for the axially displaceable guide ring 60, wherein it overlaps the guide ring 60. This prevents the retracted edge 22 that leakage air can flow through the parting line 62 of the guide ring 60 from the interior of the burner tube 20 into the interior of the flame tube 30.
  • the guide ring 60 is protected by the retracted edge 22 against the incoming air through the recirculation openings air, which has a temperature of often above 600 ° C, so that the guide ring 60 is exposed to less thermal fluctuations that could damage it.
  • the height of the cup-shaped bottom 53 of the cutting disk 50 is formed such that even when striking the guide ring 60 to the retracted edge 22, the recirculation openings 35 are not completely closed by the cup-shaped bottom 53 of the cutting wheel 50.
  • FIG. 6 shows an exploded view of an exemplary embodiment of a holder 80, with which the air nozzle 70 can be fastened to the cutting disk 50.
  • the holder 80 has a hub 81 in which the nozzle 40 can be held axially.

  • each of the braces 84 is a respective swirl wing 86, through which the air flowing through the air nozzle 70 receives a swirl, by means of which the air can be better mixed with the atomized fuel.
  • the hub 81 was supported on this ring 85, but this could lead to the fact that at high pressure of the hub 81 on the ring 85, the hub 81 could be pressed with the nozzle 40 into the air nozzle 70 inside.
  • the support elements 82 are guided in the present case by recesses 72 arranged in the peripheral edge 71 of the air nozzle 70. In this case, the support elements 82 have shoulders 83, via which the support elements 82 can be supported on the recesses 72 in the peripheral edge 71.
  • the pressure with which the air nozzle 70 is clamped on the cutting disc 50 via the holder 80 is no longer exerted via the ring 85, which rests against the nozzle 40, and the struts 84 on the air nozzle 70, but is on the support elements 82 guided on the peripheral edge 71 of the air nozzle 70.
  • the ring 85 with the braces 84 thus serves both for radial stabilization of the nozzle assembly 40 and for holding the swirl vanes 86 connected to the struts 84.
  • the risk of the hub 81 being pressed into the air nozzle 70 when the pressure is too high Air nozzle 70 to be clamped to the blade 50 is thus avoided.
  • the design of the holder 80 is independent of the configuration of the bottom 53 of the cutting disc 50th
