Definitions
- the invention relates to a method for burning hydrogen and a burner to carry out the procedure.
- Hydrogen (H2) as fuel for all types of burners, for example for combustion chambers for gas turbines, is characterized by a particularly high reactivity and thus by an extraordinary great stability of the combustion, even with excess air, such as in combustion chambers modern gas turbines occur.
- NOx nitrogen oxide
- a distribution chamber of plate-like shape for the hydrogen transverse to the flow direction of the air hereinafter referred to as the main flow direction
- the distribution chamber in the main flow direction of a variety of Air ducts with an inlet opening and an outlet opening is penetrated. Every air pipe stands with small holes, which are located near the inlet opening, with the distribution chamber in connection. If H2 is now introduced into the distribution chamber, it flows across Main flow direction to the individual holes and thus reaches the air ducts. Will now at the same time Air is blown through the air guide pipes into the combustion chamber, so both gases mix within the air pipes. The mixture produced in this way then enters the combustion chamber and is ignited.
- the arrangement of the distribution chamber makes the structure of the burner essential Simplified, as this enables individual hydrogen lines to the individual air ducts or Burning zones can be avoided.
- a plate-shaped gas burner is known from US-A 1,968,359. According to FIGS. 1 and 3 This publication has 24 air channels, four channels for each of these air channels flow the fuel so that a total of 96 individual combustion zones are created. According to these orders of magnitude one skilled in the art will recognize that these firing zones used are by no means something with micro-burning zones in the respective areas of the bores of a distribution channel from one Burner for burning hydrogen, the exemplary embodiment of which he added from the FIGS. 18 and 19 and 20 and 21 including their correlating exemplary explanations below may have to do.
- EP-A 0 334 736 cannot Clearly remove process step after the readable "when starting up the burner after injecting hydrogen and air into the combustion chamber with an air environment Fine distribution to a large number of micro-combustion zones in the respective areas of the holes is formed.
- the gas burner which has become known from EP-A 0 334 736 and which passes through several nozzles the combustion of a flame generated in the air combustible compressed gas includes one Air chamber, one wall of which is perforated with a large number of openings close together, where the flame is generated.
- the invention is based on the object of a method for the diffusion combustion of H2 and a burner to carry out this procedure so that by a drastic Increase in the burning zones a significant reduction in NOx formation compared to previous ones Burners with diffusion combustion is achieved.
- Figures 1 to 4 show a burner for burning H2 for installation, for example, in the Combustion chamber of a gas turbine.
- the burner has a plate-like shape and is transverse to the main flow direction built into the combustion chamber.
- the edge area of the burner and its connection with the combustion chamber housing, not shown, is not shown and can be designed as desired his.
- the burner consists of a first perforated plate 2 and a second perforated plate 3 passing through a plurality of guide tubes 4 are kept at a constant distance d.
- the Holes can be arranged according to certain matrix mustem.
- the first perforated plate 2 is, for example made of a suitable metal and is gas impermeable.
- the second perforated plate 3 is gas-permeable and consists of a suitable porous Material, for example made of a sintered metal.
- the holes in both plates 2, 3 are congruent attached so that each hole in the first plate 2 with the associated hole of the second plate 3 forms a pair of holes.
- the cohesion of the burner is essentially due to this made that a guide tube 4 is used as a spacer and fixed in each pair of holes.
- the guide tubes 4 have peripheral beads 5 which are rolled outwards.
- the guide tubes 4 are fixed in the perforated plate 2, for example by soldering or Welding, whereas the fixation in the plate 3, for example by rolling or flanging can be done. This results in cooperation with the bead 5 between the guide tubes 4 and the perforated plate 3 each have a positive connection.
- This essentially forms the perforated plates 2, 3 with the guide tubes 4 a distribution chamber.
- the guide pin consists of Basically a cylindrical rotating body with a stop 6a, a guide part 6b, a holder 8 and a disk 9.
- the outer diameter of the guide part 6b corresponds to in about the inner diameter of the guide tube 4 and has in the example embodiment shown four axial guide channels 7.
- the bracket 8 is attached to the right of the guide part in Figures 3 and 5 and practically represents an area with a reduced diameter, which concentrically Disc 9 carries, whose outer diameter corresponds approximately to that of the guide part 6b.
- the Stop 6a is formed by a region which is short in the axial direction and whose outer diameter is larger than that of the guide part 6b.
- a guide pin 6 is inserted until the stop 6a abuts the perforated plate 2 and is in this position permanently fixed. Such an assembly forms an injector.
- the geometry the guide pin 6 is selected so that when it is inserted up to the respective stop 6a a predetermined redirection, d. H. gives a predetermined flame shape. It is also conceivable that the stops 6a are omitted for reasons of weight. In this case the insertion takes place the guide pin 6 in the guide tubes 4 in a predetermined axial position by means of a Manufacturing device.
- the extremely simple structure of the injectors enables them to be miniaturized that a much larger number of them can be installed per combustion chamber. As a result of Miniaturization in the specified order of magnitude becomes the firing zones micro-firing zones called.
- FIGS 6 and 7 show a further embodiment of a burner, consisting of individual for the hydrogen provided elongated distribution channels 11 of U-shaped cross section, the to the combustion chamber are closed off by walls 12 made of a porous sintered metal.
- the Channels 11 are connected to one another by perforated profiles 13 of an angular cross section, that in each case the free longitudinal edges of a perforated profile 13 on the longitudinal edges of two neighboring ones Distribution channels 11 are attached.
- the holes 14 are in the strip-shaped legs the perforated profiles 13 attached at a uniform distance. To start up this burner gaseous hydrogen is introduced into the distribution channels 11. At the same time, air gets through the holes 14 are blown into the combustion chamber.
- a stoichiometric one forms in the region of each bore 14 Zone that forms its own flame when the burner is ignited.
- This burner is particularly simple and can be manufactured as a sheet metal structure. You can For example, proceed so that the U-shaped distribution channels 11 are bent from sheet metal, wherein each U-leg is connected in one piece with an obliquely angled punched tape. To the insertion of the porous walls 12 through adjacent channels 11, for example Welded together along the free edges of the paper tape. This burner is can be miniaturized in such a way that several thousand combustion zones are reached within one combustion chamber become.
- the H2 is passed through the distribution chamber or distributed over the distribution channels to thousands of micro-combustion zones, so to speak microdiffusion combustion of the hydrogen takes place.
- the main advantage of this Inverse hydrogen diffusion combustion consists of good cooling of the structure that H2 is reached.
- porous metallic ones can also be used instead of the porous sintered metals Materials are used. This is how porous materials based on metallic come Fibers into consideration, such as are known, for example, under the name "felt metal". It is also conceivable that the porous material consists of a ceramic material. To the Limit the effects of inhomogeneities possibly present in a porous material, can be a perforated plate with a defined fine hole pattern of a relatively thin layer of a porous material or used alone.
- FIGS 8 to 11 show a further embodiment of a burner, but in contrast to the previous one does not work with inverse but with regular diffusion combustion.
- That burner again consists essentially of two congruent perforated plates, here with the numbers 15 and 16 are designated.
- the two perforated plates are via guide tubes 17, each of which has an inlet opening and have an outlet opening, firmly connected to each other, so that again Distribution chamber is formed.
- Several holes 18 in are in the vicinity of the outlet openings the same angular pitch attached to the guide tubes 17.
- each guide tube 17 is a guide pin 19, consisting of a stop 20, a guide part 21 and a free jet part 22, the free jet part practically having an axial section with a reduced diameter.
- the stop 20 and the guide part 21 have a Number of axially extending grooves 23, the depth of which extends to the outside diameter of the free jet part 22 can be enough.
- the number of bores 18 corresponds to that of the grooves 23.
- a micro-combustion zone is formed downstream of a bore 18, in which there is ignition a flame stabilizes the combustion chamber.
- the guide tubes 17 in the example embodiment shown each have six bores 18, there are six micro-combustion zones per guide tube. This results in a further increase in the number of firing zones.
- An application of this principle the number of combustible zones that can be installed would be based on the TRUD combustion chamber mentioned at the beginning increase to about 5000. This in turn causes a very high level even without premixing Degree of mixing is achieved, which has the consequence that the formation of NOx is largely reduced becomes.
- By rotating and / or axially displacing the guide pins 19 with respect to the guide tubes 17 various burner settings can be made. Here too there is the possibility to omit the stops 20 and the axial position of the air guide bolts based on a appropriate device to adjust.
- Figures 12 to 15 show different settings of the burner described above.
- the guide pin with the grooves 23 is set relative to the guide tube 17 with the bores 18, that the injection of hydrogen through the holes 18 into the gaps between the air jets takes place, which arrive through the grooves 23.
- 13 shows the guide pin in a position in which the guide part 21 reaches close to the holes 18. This allows the hydrogen jet can only be diverted downstream. However, if the guide part 21 is in the guide tube 17 fixes that there is a somewhat greater distance from the bores 18, as shown in FIG. 14, can there is some recirculation.
- Fig. 15 finally shows a configuration in which the by Grooves 23 incoming air jets exactly on the hydrogen jets entering through the holes to meet.
- Figures 16 and 17 show a configuration according to which the hydrogen jets and the air jets be kept separate until they enter the combustion chamber.
- Guide tubes 17 are used with the holes 18. These are back in the perforated plates 15 and 16 are used, of which only the number 16 is shown here.
- the one used here Guide pin 24 again has the grooves 23, but is otherwise with two major changes Mistake.
- the bolt with a constant diameter is approximately up to the outlet cross section guided.
- the respective guide pin 24 is in the relevant Guide tube 17 used that each bore 18 opens into a guide channel 25. hereby is the beginning of the diffusion between hydrogen and air to an area downstream from the perforated plate 16 laid, for example, to avoid excessive thermal structural loads. at In these solutions, the flames stabilize at the mouths of the guide channels 25.
- FIGs 18 and 19 show an embodiment of a burner according to the invention for regular Diffusion combustion of the two-dimensional type.
- This burner again consists of individual provided for the H2 elongated distribution channels 26, but in contrast to the Distribution channels 11 according to Figures 6 and 7 have a closed cross section.
- This Cross-section is essentially determined by a flat rectangular shape, but in its im
- the right area (FIG. 19) has a roof edge 26a. Are on both sides of the roof edge 26a fine holes 27 attached in a staggered arrangement.
- the individual distribution channels 26 held by a bracket, not shown, at a mutual distance so that they are a grid form, which can be flowed through from left to right according to FIG. 19 by the air.
- the burner 18 further comprises a perforated plate 28, which is integrated from strip-shaped gap plates is, in the longitudinal edges gaps 29 are incorporated.
- the gap plates are between two Distribution channels 26 are fixed in the area of the bores 27 by a bracket, not shown, that each hole 27 is assigned a gap 29.
- each hole 27 is assigned a gap 29.
- instead of the one drawn hole 27 also several finer holes can be arranged.
- Figures 20 and 21 show another burner according to the invention with a one-piece perforated plate 32 with holes 32a, to which a plurality of distribution channels 33 are fastened by means of brackets 34.
- the distribution channels 33 have a long round cross section and have the perforated plate 32 in their facing area a plurality of holes 35.
- the brackets 34 can be made of wire or sheet metal. 21, each hole 32a of the perforated plate 32 has two holes 35 assigned, whereby H2 can emerge according to the arrows 37.
- Figures 22 and 23 show a further embodiment of a burner.
- the partial view according to Fig. 22 shows curved distribution channels 38, which are part of an annular burner and after 23 have a long round cross section.
- Each distribution channel forms a closed one Ring, which is connected to the hydrogen line via its own connection.
- the cohesion of the burner is arranged, for example, between the individual distribution channels 38 Wavy separators 39 are produced, for example, with the distribution channels 38 are connected by welding.
- the separators 39 are each formed from a sheet metal strip and provide a sufficient distance between the individual distribution channels 38 for the passage of air for sure.
- a distribution channel 38 with a separator 39 by winding is combined into a disc-shaped or ring-shaped burner, so that the distribution channel 38 gets a spiral shape.
