Definitions
- the invention relates to a burner for a thermal Afterburning device with a burning nozzle, the an essentially hollow cylindrical one at one end by a lid at least almost closed body has the fuel gas in the axial direction a certain pressure is supplied, which via a A plurality of main outlets in the radial direction flows.
- Thermal afterburners are said to as good an efficiency as possible, that is with one as possible low burner output that is to be disposed of Contaminants carried with exhaust air as completely as possible burn. From the point of view of complete Combustion would be a relatively high temperature the flame generated by the burner favorable; Indeed formation increases with increasing temperature of unwanted nitrogen oxides.
- the base body of the burning nozzle has a relatively small diameter; the main outflow openings for the fuel gas are located directly in the jacket of the base body.
- a uniform flame ball forms around the end region of the combustion nozzle, which, at a certain burner output, has an undesirably high temperature, at least inside. The result is the formation of undesirable nitrogen oxides.
- the object of the present invention is a burner of the type mentioned in such a way that without Loss of burner performance the formation of nitrogen oxides is reduced.
- the flame ball the burner according to the state of the art Technology, broken down into a multitude of individual flames, each with a significantly lower Temperature burns as the well known flame ball.
- the contaminants contained in the exhaust air thus significantly less nitrogen oxides arise what is very desirable for environmental reasons.
- the goal could be instead of a coherent Flame balls a variety of individual flames to be achieved in that the end region of the main body in which the main outflow openings are provided are given a correspondingly large radius and the areas of the main outlets with the gas pressure be adjusted so that the unwanted overlap the single flame is avoided. Indeed is the supply of the waste air to be disposed of to the flames not optimal with this configuration.
- An embodiment of the invention is therefore preferred, where the main outflow openings are at the ends of exhaust pipes are located by the base body protrude outwards in a star shape.
- the exhaust air can on this Way through the spaces between the discharge pipes to flow to the single flames.
- the Spaces used for visual monitoring of the flame become.
- the actual Burner output single flame which essentially are directed radially, an approximately axially directed Central flame generated.
- a flame detector for example a UV diode or an ionization detector, used to monitor the flame.
- the swirling device expediently comprises radially following at least one set of spokes externally extending blades.
- the swirling device a first set of blades that between a coaxially surrounding the burning nozzle Extend the combustion nozzle housing and an intermediate ring, and a second set of blades located between extend the intermediate ring and an outer ring.
- At least some of the blades can have one in them have twisted form.
- the burner 10 shown in Figure 1 is designed that it passes through an opening in the insulated outer case a thermal post-combustion device introduced can be. He has a fitting 11 for this purpose itself can contain an insulating layer and in assembled State the opening in the outer casing of the thermal Afterburner closes.
- a cylindrical one Burner housing 12 projects into the interior of the thermal afterburning device and carries a swirling device at its inner end, which bears the overall reference number 13. details this swirling device 13 will be shown below explained.
- the combustion chamber wall 14 is the thermal one Post-combustion device in the area of an opening 15 shown in which a cylindrical flame tube 16th is attached coaxially to the burner housing 12.
- the burner housing 12 is coaxial from a combustion nozzle 1 interspersed, the right end area in the figures 3 and 4 is shown on a larger scale. This The end region protrudes through the opening 15 of the combustion chamber wall 14 into the combustion chamber.
- the burning nozzle 1 will from a connection opening arranged outside the adapter 11 17 supplied with fuel gas.
- the burning nozzle 1 comprises a hollow cylindrical base body 1a, the at its combustion chamber, not shown facing end is closed by a cover 2.
- the lid 2 is made up of three small openings 3, which are at an angular distance of 120 ° from one another, punctured.
- the outer surface of the base body 1a is also covered by through-openings 4 interspersed in one relatively small distance from the cover 2 possessing Level.
- through-openings 4 interspersed in one relatively small distance from the cover 2 possessing Level.
- the illustrated combustion nozzle 1 has four such Passage openings 4, which are at an angular distance from each other of 90 ° each.
- the function of the passage openings 3, 4 will be explained below.
- a total of 8 openings 5 introduced which is a significantly larger Have diameters than the passage openings 3 and 4.
- the passage openings 8 have one another Angular distance of 45 ° each.
- eight discharge pipes 6 placed the star-shaped protrude radially outwards.
- the exhaust pipes too 6 are at their radially outer ends, respectively closed by a lid 7 in which there is a relative large main outflow opening 8 is located.
- the right, open end of the base body in FIG. 3 1a of the burning nozzle 1 is with a supply line for fuel gas connected in which there is preferably a flow rate increasing venturi nozzle, how this is known in and of itself.
- the one on the inner end of the burner housing 12 attached swirling device 13 includes how can be seen in particular from Figure 2, a first Set of spokes on the outer surface of the Burner housing 12 attached, extending radially Blades 18 with their radially outer ends are attached to an intermediate ring 19. Between the Intermediate ring 19 and a concentric outer ring 20 extends another set of radially extending Blades 21, the ends of which on the intermediate ring 19 or the outer ring 20 are fixed.
- the blades 18 are, as in particular in FIG. 5 can be seen in twisted. You are so between the burner housing 12 and the intermediate ring 19 or between arranged the intermediate ring 19 and the outer ring 20, that one of its longitudinal edges (in Fig 5 the edge 22) at an angle to the axis-parallel direction of about 30 °, while the other edge (in Figure 5, the edge 22) with the axis-parallel direction encloses an angle of approximately 45 °.
- the fuel gas is the combustion nozzle 1 in Figure 3 from the right fed here with a certain pressure. It flows then mainly on the relatively large areas Passage openings 5 in the jacket of the base body 1a and via the outlet pipes 6 to the main outlet openings 8. There it mixes with the one to be treated exhaust air containing pollutants, which are supplied in a suitable manner to form a flame.
- the passage openings 3 in the lid 2 and this adjacent through openings 4 in the jacket of the base body 1a generate a central flame, but over which relatively little fuel gas flows out. This can be done through an appropriate choice of the cross sections of the passage openings 3, 4 in relation to the cross section of the Determine the main outflow openings 8.
- the central flame essentially only serves to monitor the flame; she is used for this by a flame sensor, for example a UV diode, "observed".
- one of the outflow pipes 6 is also provided with a small passage opening 9.
- the fuel gas escaping here becomes one at the start of operation Ignition device supplied; the resulting flame serves as a pilot light for the radially directed, from the Outflow tubes 6 emerging individual flames and the Central flame.
- the swirling device 13 displaces the base body 1a of the burning nozzle 1 flowing, containing pollutants Exhaust air in a vortex flow.
- the through this vortex flow generated centrifugal force ensures that the flames, which are in the vicinity of the main outflow openings 8 of the Form exhaust pipes 6, still further radially outwards move and in this way an even greater distance from each other.
- every single flame burns the burning nozzle 1 with the same overall performance with considerable lower temperature than the uniform fireball of the well-known combustion nozzles, in which the from the passage openings flowing out of the outer surface of the base body Exhaust gases burned.
- the combustion gases therefore contain much less nitrogen oxides than in known thermal Nachverbrennungsvorraumen.
