Definitions

  • the present invention relates to an atmospheric burner with a feed device for preferably gaseous fuel, which has at least one feed opening which is arranged substantially centrally in the opening area of a pipe open at the end, the fuel flowing axially into the pipe under pressure and combustion air according to the Venturi principle drawn in through the pipe opening and, together with the combustion air, emerges from a burner nozzle which is connected to the other end of the pipe.
  • a feed device for preferably gaseous fuel which has at least one feed opening which is arranged substantially centrally in the opening area of a pipe open at the end, the fuel flowing axially into the pipe under pressure and combustion air according to the Venturi principle drawn in through the pipe opening and, together with the combustion air, emerges from a burner nozzle which is connected to the other end of the pipe.
  • Such burners have been known for a long time. These are used, for example, in furnaces or reactors to generate high temperatures in order to crack heavy petroleum fractions. For example, such burners are used in the production of ethylene.
  • a combustible gas is generally used as fuel, to which a certain amount of combustion air is supplied and which generates the required high temperatures when it is burned. Burners have proven their worth and have largely established themselves, which suck in the required combustion air according to the Venturi principle.
  • the burner is essentially designed as a tube which is open at one end and has a burner nozzle at its other end.
  • a feed device with a feed opening for fuel or with a fuel nozzle is arranged centrally in front of the open end face. Through this opening, the gas used, for example, for combustion flows axially into the burner tube under a pressure of a few atmospheres and thereby pulls the necessary air with it.
  • the amount of air sucked in according to the Venturi principle can be varied in many ways, for example by changing the distance of the supply opening from the pipe opening, by changing the free cross sections of the supply opening and / or pipe, changing the fuel pressure or throttling devices for the air feed to the burner.
  • the present invention has for its object to provide a burner with the features mentioned above, which is able to produce a flue gas which has significantly reduced NO x contents despite maintaining the high combustion chamber temperatures and without flue gas scrubbing.
  • Flue gas recirculation is known in principle in other combustion processes, but not for the burners to which the present invention relates. It is also important that the flue gas recirculation opens into the area of the pipe opening of such a burner. This leads to the fact that the flue gas in the Venturi tube is mixed very well with the combustion air and the fuel, so that a surprisingly strong reduction in the NO x values is obtained.
  • the cross section of the feed opening for the fuel is at most one hundredth of the cross section of a cylindrical tube part.
  • the feed opening expediently has a circular cross section. If the aforementioned cross-sectional ratio is observed, this means that the diameter of the feed opening is at most one tenth of the inner diameter of the cylindrical tube part.
  • the feed opening must not become too small, since otherwise the emerging fuel jet is too thin and therefore has too little kinetic energy to entrain combustion air to a sufficient extent and to eject it from the burner nozzle under sufficient pressure relative to the burner chamber.
  • This funnel-shaped approach advantageously has a streamlined, convexly curved inner wall.
  • the distance of the feed opening for the fuel from the free pipe end or the funnel-shaped pipe extension also represents represents an optimization parameter, but this feed opening is always in the closer region of the opening of the tube or the tube attachment and is advantageously axially adjustable.
  • An embodiment of the invention contributes to the further reduction of the NO x values, in which the feed device has a further feed opening for water vapor in addition to the feed opening for fuel.
  • the additional mixing of the fuel / air mixture with water vapor reduces the NO x content by a further 20 to 30%. It is sufficient if the mass of the water vapor supplied is one tenth of the fuel mass supplied.
  • An embodiment of the invention in which the hydrogen opening is arranged in a ring and concentrically with a circular fuel opening is particularly advantageous. This ensures good and uniform mixing across the entire cross-section of the burner tube.
  • the water vapor supply according to the invention already contributes to a reduction in the NO x values even without maintaining the above-mentioned length-to-diameter ratio of the venturi tube.
  • An embodiment of the invention is preferred in which two funnels which are axially aligned and spaced apart are provided in the opening region of the tube.
  • the fuel emerging from the supply opening initially enters the first funnel axially and, in accordance with the Venturi principle, entrains combustion air which then together with the fuel jet also enters the second funnel located at a distance, which connects directly to the Venturi tube or as funnel-shaped tube extension is formed on the Venturi tube.
  • Flue gas for example, can be supplied through the annular gap formed between the two funnels and is likewise sucked in by the central fuel jet through this annular gap.
  • the combustion air can also be drawn in through the annular gap while the flue gas is already being drawn into the first funnel.
  • the space surrounding the annular gap is preferably closed off from the outside and connected to a flue gas return line. This is the best way to control the flue gas supply.
  • flow guide vanes are provided in the interior of the burner nozzle.
  • Flow guide vanes of this type can also be provided in the end region of the venturi tube adjoining the burner nozzle, since the venturi tube and the burner nozzle merge more or less continuously into one another and the part lying in front of the outlet openings of the burner nozzle can also be considered as part of the venturi tube.
  • the burner according to the invention can be designed both as a side wall burner and as a floor burner. The differences between these two types are explained in connection with the preferred embodiments.
  • FIG. 1 shows the essential elements of the burner.
  • This essentially consists of a fuel supply device 1, a burner tube or Venturi tube 5 and a burner nozzle 6.
  • the embodiment shown in FIGS. 1 and 2 is a so-called side Wall burner, the nozzle 6 is closed at the end and has lateral slots 8, of which only one is shown as an example in Figures 1 and 2.
  • the burner is inserted into a corresponding opening in the side wall of a furnace and just protrudes with its nozzle 6 into the interior of the furnace such that the fuel mixture emerging from the slots 8 of the nozzle 6 burns in a flame close to the side wall of the furnace .
  • the burner tube 5 consists essentially of an inlet funnel 15, a cylindrical portion 5 'and a conical extension 5', which in turn merges into a more or less cylindrical part, which connects to the nozzle 6.
  • the area around the inlet funnel 15 and the interior thereof are referred to as the opening area 3 of the tube 5.
  • the opening area is the fuel supply device 1 or its fuel opening 2, which is arranged directly in front of, ie at a distance between 0 and 10 mm, the plane of the outer edge of the inlet funnel 15.
  • the feed opening 2 is preferably of circular cross-section and is aligned as precisely as possible axially to the tube 5, so that the emerging fuel jet enters the tube 5 as precisely as possible along the axis.
  • the fuel nozzle of the feed device 1 in the tip of which the feed opening 2 is arranged, is displaceable in the longitudinal direction, so that its distance from the inlet funnel 15 can be changed. If necessary, adjustment means for the axial alignment of this fuel nozzle can also be provided.
  • the inlet funnel 15 follows a cylindrical tube part 5 ', the length L is at least seven times its inner diameter D. In the dimensions shown in Figure 1, the ratio of length to inner diameter of the tube part 5 'is about 9.
  • the fuel emerges from the feed opening 2 under a pressure of a few bar, for example 2.5 bar, and axially enters the pipe 5 through the inlet funnel 15 at a relatively high speed and with corresponding kinetic energy and tears there at through the free, front opening of the inlet funnel 15 combustion air with it, which is already turbulently mixed in the pipe part 5 'with the fuel jet and after passage through the conical extension 5 ⁇ enters the nozzle 6 at reduced speed.
  • the remaining kinetic energy of the fuel / air mixture is sufficient for a slight excess pressure in the nozzle 6, so that this mixture flows out of the slots 8 and burns in the radial direction and parallel to the side wall of the furnace in which the burner is arranged.
  • flow guiding devices 21 are arranged, which ensure that even with variation of the fuel quantity and speed emerging from the supply opening 2, a favorable inflow of the slots 8 in the Burner nozzle 6 is achieved without a so-called "kickback", ie a burning process inside the nozzle and the tube 5.
  • FIG. 2 The burner shown in FIG. 2 is essentially identical to the burner shown in FIG. 1, but FIG. 2 shows some additional components and a special embodiment of the feed device 1 for the fuel.
  • the parts of the burner outside the furnace wall are shown interrupted and in reality have a length which corresponds to the burner shown in Figure 1.
  • the part of the tube 5 lying outside the furnace wall is surrounded by a housing 14 which can be fastened to the outer furnace wall.
  • This burner housing 14 serves as a supply of secondary air and can be regulated via position 12.
  • a soundproofing device 13 is arranged, the front wall 11 of which is firmly connected to the burner housing 14, so that the fuel supply device 1 can be attached to it.
  • the fuel supply device 1 has a central fuel line 9 which runs in a dashed line coaxially inside a steam line 10. These two lines 9, 10 open like a nozzle in a central burner Material opening 2 and a coaxially surrounding steam opening 7. With such a fuel supply device, water vapor under pressure is also blown axially into the burner tube 5 at the same time as the gaseous fuel.
  • the diameter of the fuel opening 2 is preferably slightly less than a tenth of the diameter D of the cylindrical tube part 5 '. This applies to all embodiments of the fuel supply device 1.
  • the cross section of the steam opening 7 surrounding the fuel opening 2 in a ring can also be kept small, so that the outside diameter of the steam opening 7 is only insignificantly larger than the diameter of the fuel opening 2.
  • the ratio of the cross section of the annular steam opening 7 to the central fuel opening 2 also determines the relative speed between the fuel jet and the steam jet, this being additionally can be varied by supplying steam and gas at different pressures.
  • FIG. 3 shows schematically how hot flue gas is drawn out of the combustion chamber 17 through a flue gas pipe 16 and fed to the opening area of the pipe 5 of the burner.
  • a double funnel 15, 15 ' is provided in the opening area of the tube 5, the exact design of which can be seen in FIG.
  • the flue gas pipe 16 opens into a closed chamber 20 which, apart from the flue gas pipe mouth, has only a central opening which is aligned with the opening of the funnel 15 which is attached to the pipe part 5 '.
  • This rear opening of the chamber 20 is ring-shaped, since a funnel 15 'is aligned with the axis of the tube 5' in the chamber 20, so that in the rear wall of the chamber 20 (seen in the direction of flow) between the outlet opening of the funnel 15 'and the An annular gap remains open through the inlet opening of the funnel 15 which the flue gas can flow into the funnel 15 and the tube 5.
  • the chamber 20 can have a cylindrical cross section and have flow guide vanes or the like in the interior and thus act as a flue gas distributor so that the inflow of flue gas through the said annular gap takes place from all sides as evenly as possible.
  • the fuel opening of the feed device 1 corresponds to the embodiments of Figures 1 or 2 and is correspondingly arranged at a close distance from the plane of the front edge of the funnel 15 '.
  • FIGS. 3 and 5 a secondary air register 18 arranged on the housing 14 and having inlet openings 19 through which secondary air for combustion can be supplied to the furnace chamber 17 past the pipe 5 and the nozzle 6.
  • FIG. 4 shows a so-called floor burner, the design of which, with the exception of the burner nozzle 6, can be very similar to the side wall burners.
  • the cylindrical part of the tube 5 of the floor burner is shown in FIG. 4 even longer than the corresponding tube part 5 'of the aforementioned side wall burner and merges practically directly into the nozzle 6.
  • the funnel at the lower pipe opening, the fuel supply device 1 and its relative arrangement to the pipe 5 as well as the housing 14, sound insulation 16 and the other parts connected to it are largely identical to those of the side wall burners mentioned above.
  • the exact design of the nozzle 6 'of the floor burner can be seen in Figures 6 and 7.
  • the nozzle 6 ' has the basic shape of a flat cylinder sector with an opening angle of approximately 90 °, nozzle openings 8' being provided in the jacket region of this cylinder sector, from which the fuel / air mixture emerges, which, as in the case of the side wall burners, may also contain flue gas and / or water vapor can be mixed.
  • FIG. 4 it can be seen how such a floor burner is arranged in a bottom recess of an oven, from FIG. 7 it can be seen that the floor burner is arranged directly next to a wall 22 of the furnace.
  • the individual nozzle openings 8 'of the nozzle 6' are arranged in certain relative angles to one another and with different diameters in two rows, as can be seen from Figure 6 and Figure 7.
  • Burners in the embodiments described here have the advantageous property that the exhaust gases generated when they are used as intended have a relatively low NO x content, which is particularly low if several of the features proposed are realized at the same time.
