Opfindelsen angâr en brænder til forbrænding af korn- el-ler partikelformet materiale, hvilken brænder er af den art, der er nærmere angivet i krav l's indledning.The invention relates to a burner for the combustion of granular or particulate material, which burner is of the kind specified in the preamble of claim 1.
De arter af brændsel, som det her f0rst og fremmest 5 drejer si.g om, er brændsel med forholdsvis h0jt gasindhold og lille partikelst0rrelse som f.eks. træmelpiller, træ-spâner og lignende.The types of fuel that this first and foremost 5 revolves around are fuel with relatively high gas content and small particle size, e.g. wooden pellets, wood shavings and the like.
Der kendes brændere med roterende forbrændingskamre, f.eks. fra US-PS 4.060.042, 3.547.056, 3.357.382,Burners with rotary combustion chambers are known, e.g. from U.S. Patents 4,060,042, 3,547,056, 3,357,382,
10 3.380.407, 3.098.458, 3.455.257 og 3.808.989 og fra DE-PS10 3,380,407, 3,098,458, 3,455,257 and 3,808,989 and from DE-PS
2.356.294. Disse patentskrifter beskriver brændere eller forbrændingsindretninger med et roterende forbrændingskam-mer i form af en i reglen forholdsvis stor roterende cy-linder. Den roterende cylinder er i de fleste tilfælde 15 forsynet med medbringéré for at tilvejebringe en omr0ring af brændselet.2356294. These patents describe burners or combustion devices having a rotary combustion chamber in the form of a generally large rotating cylinder. In most cases, the rotating cylinder is provided with carrier means to provide a stirring of the fuel.
Hvad forbrændingen angâr, medf0rer disse kendte brændere eller forbrændingsindretninger med et roterende forbræn-dingskammer den ulempe i forhdld til f.eks. forbrænding 20 pâ rist, at primærluften ikke trænger gennem brændsel-massen nedefra. I et roterende forbrændingskammer if0lge den kendte teknik kommer primærluften i hovedsagen kun i ber0ring med en fritliggende overflade pâ brændselmassen.As far as combustion is concerned, these known burners or combustion devices with a rotary combustion chamber bring about the disadvantage of e.g. combustion 20 on the grid that the primary air does not penetrate through the fuel mass from below. In a rotary combustion chamber according to the prior art, the primary air generally comes into contact only with an exposed surface of the fuel mass.
Denne ulempe afhjælpes dog delvis ved at brændselet omr0-25 res ved hjælp af fastemedbringere, der er anbragt i det roterende forbrændingskammer. Den beskrevne mâde at til-f0re primærluften pâ medf0rer desuden den ulempe, at en n0jagtig dosering af primærluft bliver særdeles vanskelig, om ikke umulig at gennemf0re.However, this disadvantage is partially mitigated by the fuel being stirred by means of fasteners placed in the rotary combustion chamber. Furthermore, the described method of supplying the primary air causes the disadvantage that an accurate dosage of primary air becomes extremely difficult, if not impossible, to implement.
30 I kendte roterende forbrændingskamre ordnes lufttilf0r-selen i reglen sâledes, at primær- og sekundærluft til-f0res sammen,ved at luften bringes til at passere hen over brændselmassen. Derved vil den forbrændingsluft, der ikke er blevet udnyttet ved primærforbrændingen, blive an-30 In known rotary combustion chambers, the air supply is usually arranged so that primary and secondary air are supplied together by causing the air to pass over the fuel mass. Thereby, the combustion air that has not been utilized in the primary combustion will be used.

2 vendt sont sekundærluft.2 reversed sound secondary air.
Af det foregâeiide fremgâr det, at heller ikke tilf0rselen af sekundærluft kan reguleres med en st0rre n0jagtighed.It is clear from the foregoing that the supply of secondary air cannot be controlled with greater accuracy.
I roterende forbrændingskamre, der er udformet i overens-5 stemmelse med den kendte teknik, foreligger sâledes den ulem-pe, at en usikker tilf0rsel af primærluft og en vanskelig regulerbar tilf0rsel af sekundærluft forhindrer en fra brændsel0konomisk synspunkt effektiv udnyttelse af brænd-selets varmeværdi.Thus, in rotary combustion chambers designed in accordance with the prior art, there is the disadvantage that an uncertain supply of primary air and a difficult controllable supply of secondary air prevent an efficient use of the fuel's heat value from a fuel economy point of view.
10 Det er opfindelsens formâl at anvise udformningen af en brænder af den indledningsvis nævnte art, hvormed de ovenfor angivne ulemper og begrænsninger kan overvindes. Dette formai opnâs ved en brænder, som if0lge opfindelsen er ejendom-melig ved den i krav l's kendetegnende del udformning.It is the object of the invention to provide the design of a burner of the type mentioned above, by which the disadvantages and limitations mentioned above can be overcome. This object is achieved by a burner which according to the invention is peculiar to the characterizing part of claim 1.
15 Ved denne udformning opnâs en sâdan fordeling af forbræn-dingsluften, at en veldefineret luftmængde tilf0res brænd-selet i form af primærluft, og den resterende luftmængde, som ogsâ er kvantitativt veldefineret, ledes gennem det roterende forbrændingskammer frem til dettes âbning, hvor 20 denne luft tilf0res de brændbare gasser, som er blevet frigjort i forbrændingskammeret.In this embodiment, such a distribution of the combustion air is obtained that a well-defined quantity of air is supplied to the fuel in the form of primary air, and the remaining quantity of air, which is also quantitatively well defined, is fed through the rotary combustion chamber to its opening. air is fed to the combustible gases which have been released into the combustion chamber.
En meget effektiv forbrænding muligg0res ved at forbræn-dingskammerets kegleformede udmunding mod kedlen er kera-misk isoleret og muligg0r en forbrænding af gasser ved en 25 temperatur pâ 1300°C. Ved at begrænse lufttilf0rselen er det muligt at regulere temperaturen i primærforbrændings-zonen med henblik pâ at undgâ slaggedannelse. Samtidigt kan der i sekundærforbrændingszonen opretholdes et sâdant temperaturniveau, at der opnâs en h0j forbrændingsvirk-30 ningsgrad.A very efficient combustion is made possible by the cone-shaped opening of the combustion chamber against the boiler being ceramic insulated and enabling the combustion of gases at a temperature of 1300 ° C. By limiting the supply of air, it is possible to regulate the temperature of the primary combustion zone in order to avoid slag formation. At the same time, in the secondary combustion zone, such a temperature level can be maintained to achieve a high combustion efficiency.
Opfindelsen skal i det f0lgende forklares nærmere under henvisning til tegningen, pâ hvilken 3The invention will now be explained in more detail with reference to the drawing, in which:

Figure 2 is an enlarged scale view showing the pipelines for supplying primary air and secondary air; 3 is a cross-section along line III-III of FIG. 2, showing the supporting tube and a vent plate distributing the primary air to different ducts; and FIG. Figure 4 is an enlarged partial cross-section through the combustion chamber showing the effect of the combustion chamber's combined means for stirring and supplying primary air.
Den i figurerne viste forbrændingsindretning er anbragt i et ydre rum 2, der er vandret og cylindrisk udformet, og er anbragt i tilslutning til en varmekedel. I det ydre rum 2 er der anbragt et roterende forbrændingskammer 1, 15 et faldr0r 20 for tilf0rsel af brændsel, et aksialbevæge-ligt r0r 5 for tilf0rsel af sekundærluft, et roterende og bærende r0r 4, to lejer 3, der underst0tter r0ret 4, samt en bageste cylinder 14, som ikke roterer. I r0ret 4 er der anbragt et indre r0r 7, som holdes koncentrisk i 20 forhold til r0ret 4 ved hjælp af otte skillevægge 9, der ligger i planer indeholdende r0ret 4's symmetri- og om-drejningsakse og er jævnt fordelt omkring r0ret 4's in-dervæg. Det herved. opstâede kapperum mellem r0ret 4 og r0ret 7 er herved opdelt i otte kanaler 10. Hver enkelt 25 af kanalerne 10 er gennem en âbning 23 forbundet med en af otte arme 8.The combustion device shown in the figures is arranged in an outer space 2, which is horizontally and cylindrically formed, and is located adjacent to a heating boiler. In the outer compartment 2, a rotary combustion chamber 1, 15 is provided with a drop pipe 20 for supply of fuel, an axially movable pipe 5 for the supply of secondary air, a rotary and support pipe 4, two bearings 3 supporting the pipe 4, and a rear cylinder 14 which does not rotate. In the tube 4, an inner tube 7 is placed which is kept concentric in relation to the tube 4 by means of eight partitions 9, which lie in planes containing the axis of symmetry and rotation of the tube 4 and are evenly distributed around the inner wall of the tube 4. . Hereby. formed sheath space between the tube 4 and the tube 7 is thereby divided into eight channels 10. Each of the 25 channels 10 is connected through an opening 23 to one of eight arms 8.
Fig. 2 viser en ventiiplade 12, som kan drejes omkring en akse, der faider sammen med omdrejningsaksen for r0ret 4.FIG. 2 shows a valve plate 12 which can be rotated about an axis that coincides with the axis of rotation of the tube 4.
Inden i det roterende forbrændingskammer 1 er der anbragt 30 otte r0rformede arme 8>, som er fast forbundet med det roterende r0r 4. Armene 8 er ogsâ fastgjort i forhold til forbrændingskammeret 1, som bæres af armene 8. I den ende af det roterende forbrændingskammer 1, der udmunder i var-mekedelen, er der udformet en rund âbning 11. Forbrændings- 4Within the rotary combustion chamber 1, eight tubular arms 8 are attached, which are fixedly connected to the rotary tube 4. The arms 8 are also fixed relative to the combustion chamber 1 carried by the arms 8. At the end of the rotary combustion chamber 1, which opens into the heating element, a circular opening 11 is formed.

Ogsâ i den modsatte ende er der i forbrændingskammeret 1 udformet en cirkelrund âbning, som star i forbindelse til den faststâende cylinder 14. Faldr0ret 20 er fast forbun-5 det med cylinderen 14, hvori der er anbragt en bageste glideplade 18, der bærer et tætningsorgan 15, som tætner det roterende r0r 41 s gennemf0ring gennem den bageste glideplade 18. En bageste keglekappe 17, som ved hjælp af en flangeforbindelse 26 er fast forbundet med forbrændingskam-10 meret 1, ligger tætnende an imod en cirkelrund tætningsfla-de pâ cylinderen 14.Also at the opposite end, in the combustion chamber 1, a circular aperture is formed, which is connected to the standing cylinder 14. The drop pipe 20 is fixedly connected to the cylinder 14, in which is arranged a rear sliding plate 18 carrying a sealing means. 15 which seals the passage of the rotary tube 41 through the rear slide plate 18. A rear cone cap 17, which is fixedly connected to the combustion chamber 10 by means of a flange connection 26, seals against a circular sealing surface of the cylinder 14 .
Armene 8 er fastgjort til det roterende r0r pâ det sted, hvor det roterende r0r 4 udviser et antal âbninger 23.The arms 8 are attached to the rotary tube at the location where the rotary tube 4 exhibits a plurality of openings 23.
Disse âbninger 23 udg0r en fortsættelse af de r0rformede 15 arme 8's indvendige hulrum. Âbningerne 23 muligg0r sâledes genneml0b af primærluft, som gennem kanalerne 10 tilf0res de r0rformede arme 8.These openings 23 constitute a continuation of the inner cavity of the tubular 15 arms 8. The openings 23 thus allow the passage of primary air, which is fed through the ducts 10 to the tubular arms 8.
Ved drejning af ventilpladen 12 kan primærluften fordeles pâ en sâdan mâde, at kun visse af kanalerne 10 og dermed 20 kun visse arme 8 fâr primærluft. Primærluften skal i ho-vedsagen kun tilf0res armene, nâr disse bevæger sig opad.By turning the valve plate 12, the primary air can be distributed in such a way that only certain of the ducts 10 and thus 20 only certain arms 8 receive primary air. In the main case, the primary air should only be supplied to the arms as they move upwards.
Ved en normal indstilling af ventilpladen 12 og ved et for-brændingskammer 1 med otte arme 8 kan der f.eks. tilf0res primærluft til den arm 8, der befinder sig i sin nederste 25 stilling, samt til yderligere tre arme, der bevæger sig opad. De 0vrige fire arme fâr sâledes ingen lufttilf0rsel.In a normal setting of the valve plate 12 and by an combustion chamber 1 with eight arms 8, e.g. primary air is supplied to the arm 8 which is in its lower 25 position, as well as to another three arms moving upwards. The other four arms thus have no air supply.
En luftpassage 6 danner forbindelse mellem det indre r0r 7 og det forreste r0r 5. Luftpassagen 6 kan g0res st0rre eller mindre ved at bevæge r0ret 5 i aksialretningen. Der-30 som r0ret 5 bevæges nærmere til r0ret 4, formindskes sâledes luftpassagen 6, hvorigennem forbrændingsluften til-f0res 5 fra r0ret 7.An air passage 6 forms a connection between the inner tube 7 and the front tube 5. The air passage 6 can be made larger or smaller by moving the tube 5 in the axial direction. As the pipe 5 moves closer to the pipe 4, the air passage 6 is thereby reduced, whereby the combustion air is fed 5 from the pipe 7.

I den forreste ende af det aksialbevægelige r0r 5 findes en âbning 19, hvorigennem sekundærluften fra r0ret 5 til-5 f0res uforbrændte brændselsmolekyler, som tilf0res ovn-ruiranet gennem âbningen 11 i det roterende forbrændings-kammer 1. I den forreste ende af r0ret 5 er der anbragt et organ 16 eller skrâtstillede ribber, der er indrettet til at meddele sekundærluften en turbulens.At the front end of the axially movable tube 5 there is an opening 19 through which the secondary air from the tube 5 to 5 is fed unburned fuel molecules, which are fed to the furnace ruirane through the opening 11 in the rotary combustion chamber 1. At the front end of the tube 5 is there is provided a member 16 or inclined ribs adapted to impart a turbulence to the secondary air.
10 Fig. 4 viser, hvorledes brændselmaterialet omr0res og I0ftes af armenef8, som kan være forsynet med ribber. Forbrændingskammeret l's omdrejningsretning er som vist med pilen 21. Huiler 13 i armene 8 er rettet sâledes, at luften udblæses i en retning svarende til omdrejningsret-15 ningen for forbrændingskammeret 1. Primærluften udblæses sâledes i den retning, der er angivet af pilene 22. Pâ denne mâde fâr primærluften lejlighed til at trænge igen-nem brændselmassen. Imidlertid kan det i visse tilfælde, navnlig ved st0rre anlæg, være hensigtsmæssigt at udblæse 20 primærluften til begge sider.FIG. Figure 4 shows how the fuel material is stirred and lifted by arm nose 8 which may be provided with ribs. The direction of rotation of combustion chamber 1 is as indicated by arrow 21. Huiler 13 in the arms 8 is directed so that the air is blown in a direction corresponding to the direction of rotation of the combustion chamber 1. The primary air is thus blown out in the direction indicated by arrows 22. On this way the primary air is allowed to penetrate the fuel mass. However, in some cases, especially in larger plants, it may be appropriate to blow out the primary air to both sides.
Foruden at tilf0re primærluft til brændselet i primærfor-brændingsfasen harde r0rformede arme 8 ogsâ til opgave at bearbejde brændselet mekanisk og at I0fte dette med sig gennem ca. en trediedels omdrejning og derefter lade brænd-25 selet falde ned gennem en skrât opadrettet luftstr0m, der skriver sig fra hullerne 13.In addition to supplying primary air to the fuel in the primary combustion phase, hard tubular arms 8 are also assigned the task of machining the fuel mechanically and lifting it with it through approx. a third turn and then allow the fuel to fall down through an oblique upward flow of air emerging from the holes 13.
Den mekaniske bearbejdning bevirker, at asken frig0res fra brændselet, og ved at primærluften tilsættes nedefra, l0f-tes den lette aske op mod forbrændingskammerets centrum, 30 nâr brændselet faider ned. Luftstr0mmen fra hullerne 13 river asken med sig ud fra forbrændingskammeret, og pri-mærforbrændingen bliver effektiv uden hæmmende aske pâ eller omkring brændselet.The mechanical machining causes the ash to be released from the fuel and, by adding the primary air from below, raises the light ash towards the center of the combustion chamber as the fuel fades. The air stream from the holes 13 tears the ashes out of the combustion chamber, and the primer combustion becomes effective without inhibiting ash on or around the fuel.

Forbrændingsluften kommer sâledes ind til brænderen fra blæseren gennem det roterende r0r 4. Gennem kanalerne 10 og âbningerne 23 i r0ret 4 ledes primærluften ud til ar-mene 8 og til hullerne 13. Primærluften tilf0res sâledes 5 forbrændingskammeret 1 i nærheden af kammerets indvendige kappeflade, hvorfra primærluften gennemtrænger brændsel-massen hen mod centrum i forbrændingskammeret 1. I forbin-delse med primærforbrændingen i forbrændingskammeret 1 dan-nes brændbare gasser, som gennem âbningen 11 ledes ud fra 10 forbrændingskammeret 1 og tilf0res sekundærluft til for-brænding af disse gasser.The combustion air thus enters the burner from the fan through the rotating tube 4. Through the ducts 10 and the openings 23 in the tube 4, the primary air is discharged to the arms 8 and to the holes 13. The primary air is thus supplied to the combustion chamber 1 near the inner casing surface of the chamber. the primary air penetrates the fuel mass towards the center of the combustion chamber 1. In connection with the primary combustion in the combustion chamber 1, combustible gases are formed which are discharged through the opening 11 from the combustion chamber 1 and secondary air is supplied for combustion of these gases.
Sekundærluften indf0res i r0ret 5 gennem spalten 6. Sekun-dærlufttilf0rselen kan reguleres ved aksialforskydning af r0ret 5. Tilf0rselen af primærluft kan f.eks. reguleres 15 ved hjælp af en spjæld-indretning af i sig selv kendt art.The secondary air is introduced into the pipe 5 through the slot 6. The secondary air supply can be regulated by axial displacement of the pipe 5. The supply of primary air can e.g. 15 is regulated by means of a damper device of a kind known per se.
De n0dvendige organer til aksialforskydning af r0ret 5 kan være af i sig selv kendt art, og er for overskuelighedens skyld ikke vist pâ tegningen.The necessary means for axial displacement of the tube 5 may be of a kind known per se, and for the sake of clarity are not shown in the drawing.
Doseringsenheden 24 og faldr0ret 20 er sâledes udformet, at dannelsen af en sammenhængende brændselstreng fra for-20 râdet til forbrændingskammeret er undgâet, hvad der ellers kunne medf0re en risiko for bagudskridende forbrænding.The metering unit 24 and the downpipe 20 are designed so that the formation of a coherent fuel strand from the reservoir to the combustion chamber is avoided, which could otherwise pose a risk of backward combustion.
Det pâ tegningen viste udf0relseseksempel har otte arme 8.The embodiment shown in the drawing has eight arms 8.
For forskellige arter af brændsel og forskellige dimensio-ner pâ ovnen og pâ forbrændingskammeret 1 kan det være hen-25 sigtsmæssigt at hâve enten flere eller færre arme 8. Sâledes kan forbrændingskammeret 1 f.eks. være udf0rt med fem eller ni arme.For different types of fuel and different dimensions of the furnace and of the combustion chamber 1, it may be convenient to raise either more or fewer arms 8. Thus, the combustion chamber 1 can e.g. be made with five or nine arms.
Det er nævnt i det foregâende, at armene 8 kan være forsy-net med ribber til omr0ring af brændselet. For visse arter 30 af brændsel og navnlig ved visse partikelst0rrelser kan det imidlertid være hensigtsmæssigt at hâve særskilte organer til tilf0rsel af primærluft, som f.eks. kan ligge mellem ribber, der er direkte fastgjort til indersiden af 7It is mentioned above that the arms 8 may be provided with ribs for stirring the fuel. However, for certain species of fuel 30, and in particular for certain particle sizes, it may be appropriate to have separate means for supplying primary air, such as e.g. may lie between ribs directly attached to the inside of the 7

Det pâ tegningen viste forbrændingskammer 1 har en om-drejningssymmetrisk form. Forbrændingskammeret 1 kan imidlertid være udformet sâledes, at det i tværsnit har 5 form af en polygon. Ved en sâdan udformning vil allerede selve udformningen af forbrændingskammeret 1 medf0re en vis omr0ring i forbindelse med drejning af forbrændingskammeret 1.The combustion chamber 1 shown in the drawing has a rotationally symmetrical shape. However, the combustion chamber 1 may be designed to have a polygon in cross section 5. In such a design, the very design of the combustion chamber 1 will already cause some stirring in connection with the rotation of the combustion chamber 1.
