Definitions
- the invention relates to a burner for mixing and Combustion of at least two combustion media, according to the preamble of claim 1.
- Combustion air in particular can be used in such burners and a lean gas can be used as the fuel gas.
- the burners comprise several burner nozzles, each a tube, which to supply a combustion medium to one Combustion chamber extends, and an inflow device for the other combustion medium on the combustion chamber side End of the tube can be provided.
- a generic burner is known from US 5,267,850, in which a burner system and a combustion process for High temperature applications are described. At a This burner nozzle becomes a central high-speed fuel flow generated the circular is surrounded by a low speed current.
- Another burner is used in the hot gas generator, which emerges from DE 42 08 951 C2.
- This known burner has to supply a combustion medium Pipes on, the free ends of outlet nozzles surrounded for the inflow of a second combustion medium are. With this known arrangement a very good burnout result with a short burner flame reached. Nevertheless, it is desirable to use the well-known burner in terms of degree of burnout and flame length even further to improve.
- the invention has for its object to provide a burner which ensures the most complete possible combustion of combustion media even with very low calorific values with a short flame.
- a burner with the characterizing features of claim 1 solved. It is one Burner nozzle with at least three coaxially arranged Pipes provided, namely an inner Core tube, an outer tube and at least one intermediate pipe arranged between them. The pipes are to each other in the radial direction to form annular gap channels spaced, through which combustion media in the combustion chamber are conductive.
- the flame on the burner nozzle can be in almost everyone desired way. So can accordingly the number of openings more than two combustion media can be used with different pressures.
- the at least three concentrically arranged to each other Burner nozzle openings will also mix intensely of the combustion media and thus a particularly large one Guaranteed combustion surface. This has a short one Flame and a very good burnout result.
- the stepped arrangement of the tubes in the axial direction to each other therefore allows an optimal time and place offset mixing of the gases.
- An advantage of the burner according to the invention is the possibility of being able to operate it with so-called lean gas, which is a fuel gas with a relatively low calorific value.
- lean gas which is a fuel gas with a relatively low calorific value.
- a particularly good combustion result is achieved that the pipes differ in the combustion chamber extend.
- the pipes of the burner nozzle are pointing so a tiered arrangement.
- the burner nozzle openings to each other in the axial direction of the tubes transferred. This mixes the different ones gaseous combustion media staggered in time and place, which leads to a particularly good mixing of the media.
- the outer tube continues in the Combustion chamber extends as the intermediate pipe.
- the outer tube thus forms a lateral limitation of the burner nozzle, whereby the influence of neighboring burner nozzles on the Mixing process is largely avoided.
- the core tube extends further into the combustion chamber than that Intermediate tube. In this way, mixing first takes place of the combustion media, which come from the annular gap channels stream. After mixing in the side areas the burner nozzle becomes an additional swirl and thus a particularly large contact area between the Combustion media reached by the flow from the core tube.
- a development of the burner according to the invention exists in that a chamber is provided for each combustion medium which is line-connected to each burner nozzle is.
- the individual separate chambers point in turn inlets through which the respective combustion medium flows into the associated chamber, whereby in the Chambers the respective pressure of the combustion medium in a simple manner can be adjusted.
- This embodiment is further developed in that three Chambers are provided, of which a first chamber with the core tube, a second chamber with the core tube and Intermediate tube formed annular gap channel and a third chamber with that formed by the intermediate tube and outer tube Annular gap channel are connected.
- a first combustion medium therefore flows over the first Chamber and the core tube in the combustion chamber.
- the second Combustion medium flows over the second chamber and the associated annular gap channel in the combustion chamber while the third combustion medium through the third chamber and the other annular gap channel is passed.
- An alternative embodiment is that two Chambers are provided, one with the core tube and an annular gap channel is connected. The other chamber is then corresponding with the one or more remaining Annular gap channels connected. For example two combustion media through several separate Flow burner nozzle openings into the combustion chamber, resulting in a high desired level of turbulence leads.
- the burner nozzle has four tubes. So there exist alongside the core tube opening a total of three annular gap openings. Consequently, four combustion media can be used in this embodiment can be fed separately. Using Individual combustion media can use fewer combustion media through several burner nozzle openings to reach be mixed well. So far special applications justify the design effort, can of course have burner nozzles with five or more pipes are provided.
- the swirl devices can be essentially radially directed nozzles.
- a particularly simple and effective swirl device, for example for the core tube lies in the formation of radial directed holes in the core tube wall, the free end of the core tube is closed with a plate.
- the burner according to the invention is further developed that a start burner is provided to the the burner nozzles are arranged around.
- the start burner is used with separate combustion media, in particular a high quality fuel gas. After a certain The starting torch can then be switched off again become.
- a particular advantage of the invention is that one the combustion media a sulfur-containing gas, in particular can also be hydrogen sulfide.
- gases which have so far mostly been disposed of at great expense could now with the burner according to the invention are usefully thermally burned or recycled.
- FIG. 1 shows an inventive one Burner 10 with a burner nozzle 11, which made up of three coaxial tubes is.
- the inner tube is referred to as core tube 20, which of an intermediate tube 30 and an external Outer tube 40 is surrounded.
- the core tube 20 is connected to the wall via a flange 24 a first chamber 21 connected so that a first combustion medium 28 through an inlet 23 through the first Chamber 21 can flow into the core tube 20.
- the flange 24 is by a suitable connection, for example a Weld or a gas-tight screw connection on the Wall of the first chamber 21 around a through opening 22 attached.
- the core tube extends from the first chamber 21 20 through a second chamber 31 and a third chamber 41 towards a combustion chamber 12, in which the combustion process takes place.
- a second or so-called intermediate pipe 30 via a Flange 34 attached.
- the inner diameter of the intermediate pipe 30, which is coaxial towards the combustion chamber 12 extends is larger than the outer diameter of the core tube 20 so that a first annular gap channel 39 between the core tube 20 and the intermediate tube 30 is formed.
- a second combustion medium can pass through this first annular gap channel 39 38 via an inlet 33 and the second chamber 31 flow to the free end of the burner nozzle 11.
- the core tube 20 and the intermediate tube 30 are from the third Chamber 41 surrounded by an outer tube 40, which is coaxial to the other two tubes towards the Combustion chamber 12 extends.
- the outer tube 40 In the same way as for the other two tubes is the outer tube 40 by one Through opening 42 on a wall on the combustion chamber side the third chamber on this by means of a flange 44 attached.
- the inner diameter of the outer tube 40 is again larger than the outer diameter of the intermediate tube 30, so that a second annular gap channel 49 is formed.
- a third combustion medium can pass through this annular gap channel 49 48 via an inlet 43 and the third chamber 41 flow into the combustion chamber 12.
- Burner with a three-chamber arrangement is usually used through the core tube 20 and the first annular gap channel or two fuel gases passed during the second annular gap channel 49 is used to supply combustion air.
- acidic gases are passed, for example Gases containing hydrogen sulfide of the same or different concentration.
- the outer tube 40 extends further into the combustion chamber 12 into it than the core tube 20, which in turn continues in the combustion chamber 12 extends as the intermediate pipe 30.
- the second combustion medium is the first 38, which emerges from the opening of the first Annular gap channel 39 emerges with the third combustion medium 48 mixed, which from the outlet opening of the second annular gap channel 49 flows. Only after mixing of the second and third combustion medium 38, 48 flows the first combustion medium 28 from the core tube 20 in the Mixing zone 13, so that this adds another to the first mixing process, spatially and temporally staggered turbulence takes place.
- the individual combustion media 28, 38, 48 are swirl devices 25, 35 on the core tube 20 and the intermediate tube 30 provided.
- the swirl devices 25, 35 each exist from an end plate 26, 36, which on the combustion chamber side End of the core tube 20 or the intermediate tube 30 is attached. Via radially directed holes or grooves 27, 37 the respective combustion medium flows 28, 38 in the radial direction into the mixing zone 13.
- the second annular gap channel 49 is particularly strong Swirling.
- FIG. 2 is a reduced front view of the invention Brenners 10 shown. From this it can be seen that a centrally located start burner 14 is provided around which a plurality of burner nozzles 11 are arranged are, partially for reasons of clarity only their centers are shown. In the example is also shown only a nozzle of the inlet 23 by which the first combustion medium 28 into the first chamber 21 flows. Second and third inlet connections are a matter of course negotiate.
- the burner according to the invention which has a large number of individual burner nozzles 11, therefore creates a large surface for the combustion. It is therefore possible to burn hydrogen sulfide-containing or acid-containing gases with this burner, these acid-containing gases preferably being mixed very intensively with the combustion air flowing perpendicularly thereto.
- the burner can be regulated so that in such a case the start burner is put back into operation immediately in order to maintain the required outlet temperature of the burner.
