Definitions
- the present invention relates to a burner for operating an assembly for Generation of a hot gas according to the preamble of claim 1.
- the invention seeks to remedy this.
- the invention as set out in the claims is characterized, the task is based on a burner at the beginning to submit proposals that address the above imperfections and to remedy shortcomings.
- the main advantage of the invention is that the main body of the burner remains essentially unchanged.
- the inner walls of those forming the burner Shells built-in guide bodies, which take over the task, in advance the combustion air flowing purely tangentially into the interior of the burner, which preferably consists of an air / exhaust gas mixture, in the axial direction redirect.
- the inflow angle of this guide body which preferably are designed as guide vanes, seen from the burner tip in the direction of flow. In the area of the burner outlet, these guide bodies have up to a vertical position with respect to the burner axis. So that these Guides can work properly, their number will be within the length of the Brenners chosen so that the ratio between the distance of the guide body to each other and the width of the tangential inflow channel into the interior of the Brenners is approximately 1.
- Fig. 1 shows a premix burner in perspective.
- Fig. 2 possibly Fig. 3 are used.
- the the first-mentioned figures have mainly the purpose, the type and the functioning of such a burner.
- the premix burner according to FIG. 1 consists of two hollow conical partial bodies 1, 2, which are nested offset from one another. That burner is operated with a gaseous and / or liquid fuel.
- cone-shaped here is not only that shown by a fixed opening angle understood cone shape understood, but it also closes other configurations of the partial body, such as a diffuser or diffuser-like Shape, as well as a confuser or confuser-like shape. These forms are not specifically shown here, since they are familiar to the person skilled in the art are.
- the offset of the respective central axis or longitudinal axis of symmetry Partial body 1, 2 to each other see Fig. 2, Pos.
- each one tangential air inlet duct 5, 6 free through which the combustion air 7 in the interior of the premix burner, i.e. in the cone cavity 8 flows.
- the two conical partial bodies 1, 2 each have one cylindrical initial part 9, 10, which also, analogous to the aforementioned partial bodies 1, 2, offset from each other, so that the tangential air inlet channels 5, 6 are present over the entire length of the premix burner.
- a nozzle 11 for preferential atomization a liquid fuel 12 housed such that their injection approximately with the narrowest cross section of that formed by the partial bodies 1, 2 Cone cavity 8 coincides.
- the injection capacity and the operating mode this nozzle 11 depends on the given parameters of the respective Premix burner.
- the fuel 12 injected through the nozzle 11 can if necessary, be enriched with a recirculated exhaust gas; then it is also possible, through the nozzle 11, the complementary injection of an amount of water to accomplish.
- the premix burner can be purely conical, i.e. without a cylindrical one Initial parts 9, 10 may be formed.
- the sub-bodies 1, 2 also each have one Fuel line 13, 14, which runs along the tangential inlet channels 5, 6 are arranged and provided with injection openings 15, through which preferably a gaseous fuel 16 in the combustion air flowing there 7 is injected, as is symbolized by arrows 16, wherein this injection also the fuel injection level (see FIG. 2, item 22) of the Systems forms.
- These fuel lines 13, 14 are preferably at the latest placed at the end of the tangential inflow, before entering the cone cavity 8, this to ensure an optimal air / fuel mixture.
- the premix burner On the combustion chamber side, the premix burner has an anchorage for the partial bodies 1, 2 serving front panel 18 with a number of holes 19 through which if necessary, a mixed or cooling air 20 the front part of the combustion chamber 17th or whose wall is fed.
- the premix burner is used solely by means of a liquid Operated fuel 12, this is done via the central nozzle 11, wherein this fuel 12 then enters the cone cavity 8 at an acute angle or is injected into the combustion chamber 17.
- the nozzle 11 thus forms a tapered fuel profile 23 rotating from the tangentially flowing Combustion air 7 is enclosed. In the axial direction, the concentration of the injected fuel 12 continuously through the incoming combustion air 7 broken down into an optimal mixture.
- a backflow zone 24 (vortex breakdown) also forms there with one opposite the flame front 25 acting there stabilizing effect, in which Meaning that the backflow zone 24 functions as a disembodied flame holder takes over.
- the optimal fuel concentration across the cross section is only in the area the vortex runout, that is, in the area of the backflow zone 24. First a stable flame front 25 then arises at this point.
- the design of the premix burner is suitable furthermore excellent, the flow opening of the tangential air inlet ducts 5, 6 to change as required, which means without changing the overall length of the premix burner a relatively large operational bandwidth can be covered.
- the partial bodies 1, 2 are also in a different plane to one another displaceable, which even overlaps the above the air inlet plane into the cone cavity 8 (see FIG. 2, item 21) in the same Area of the tangential air inlet ducts 5, 6, as can be seen from FIG. 2, can be accomplished. It is then also possible to pass through the partial bodies 1, 2 to interleave a counter-rotating movement in a spiral.
- the premix burner is not open the number shown is limited. A larger number is displayed there, for example, when it comes to making the premixing wider, or the Swirl number and thus the dependent formation of the backflow zone 24 by to influence a larger number of air inlet ducts accordingly.
- Premix burners of the type described here are also those for which Achieving a swirl flow from a cylindrical or quasi-cylindrical It is assumed that the combustion air flows into the interior of the pipe Pipe via tangentially arranged air inlet ducts, and inside the tube a conical body with decreasing in the direction of flow Cross-section is arranged, which also with this configuration critical swirl number can be achieved at the outlet of the burner.
- FIG. 2 shows the same premix burner according to FIG. 1, but from a different one Perspective and in a simplified representation.
- This Fig. 2 is essentially serve to correctly record the configuration of this premix burner.
- This offset is a measure of the size of the flow width resp. the flow cross section of the tangential air inlet ducts 5, 6.
- the respective central axes 3, 4 run parallel to one another here.
- Fig. 3 is a section approximately in the middle of the premix burner.
- the mirror image Tangentially arranged feed channels 27, 28 each perform the function of a Mixing section in which the combustion air 7, which consists of fresh air 29 and recirculated flue gas 30 is formed, is perfected.
- the combustion air 7 is processed in an injector system 200. Upstream of each feed channel 27, 28, as a tangential inflow into the interior 8 of the premix burner serves, the fresh air 29 over the entire length of this premix burner evenly distributed over perforated plates 31, 32. In the direction of flow to the tangential Inlet channels 5, 6, these perforated plates 31, 32 are perforated.
- the perforations perform the function of individual injector nozzles 31a, 32a, which have a suction effect exercise against the surrounding flue gas 30 such that each of these Injector nozzle 31a, 32a only sucks in a certain proportion of flue gas 30, whereupon over the entire axial length of the perforated plates 31, 32, that of the burner length corresponds, a uniform flue gas admixture takes place.
- This Configuration means that the two media, ie the Fresh air 29 and the flue gas 30, an intimate mixing takes place, so that the flow length extending up to the tangential air inlet ducts 5, 6 of the feed channels 27, 28 can be minimized for the mixture formation can.
- the local injector configuration 200 is characterized by that the geometry of the premix burner, especially what the shape and the Concerns the size of the tangential air inlet ducts 5, 6, remains dimensionally stable, i.e. by along the evenly metered distribution of the hot smoke gases 30 along The entire axial length of the premix burner does not result in any heat-related Faults.
- the same injector configuration as the one just described here can also in the area of the head-side fuel nozzle 11 for a axial supply of combustion air can be provided.
- the feed channels 27, 28 also have guide plates 50, which are described in the description of FIGS Fig. 4 is discussed in more detail.
- FIG. 4 is a schematic illustration of the premix burner in the direction of flow, in particular expressing the course of the perforated plates 31, 32 belonging to the injector system in relation to the inflow planes 33 of the feed channels 27, 28.
- This course is parallel, the inflow planes 33 also running parallel to the burner axis 26 of the premix burner over the entire burner length.
- This figure also shows how the injector nozzles 31a, 32a are mounted. There are two possibilities here of guiding the injector nozzles 31a, 32a. On the one hand, the upper illustration shows a completely vertical course of the injector nozzles 32a.
- the lower illustration shows a different course of the injector nozzles 31a: Here they have an inflow angle which changes continuously in the direction of flow with respect to the burner axis 26. From an initially acute angle in the area of the head stage of the premix burner, this gradually increases until the injector nozzles 31a in the area of the burner end are then approximately perpendicular to the burner axis 26.
- Which design variant is used depends on the specific operating parameters and other auxiliary measures. Mixed forms of vertical and oblique injection are also possible.
- the partial bodies 1, 2 are equipped with guide vanes 50.
- the inflow angle a ie the angle of the corresponding guide vane with respect to the burner axis 26, increases from the burner head to the burner outlet, the angularity of these guide vanes 50, of course, being dependent on the respective inflow plane of the injector nozzles 31a, 32a.
- the last-acting guide vane is essentially almost perpendicular to the burner axis 26.
- the angle increases with vertically acting injector nozzles 31a from initially approximately 40 ° to an angle ⁇ n of approximately 80 °.
