I behallarens 1 undre del ar anordnad en ringformig botten 2, pa vars Ovre yta är anordnad en eldfast bekladnad 3. I delarnas 2 och 3 mittparti finnes ett utlopp 4. Det i styckeform utbildade branslet, som kan vara rnindervardigt, t. ex. tory eller brunkol, är placerat uti behollarens 1 inre rum 5 Over den eldfasta bekladnaden 3. Forbranningsrummet befinner sig Over utloppet 4. The apparatus shown in Figs. 1 and 2 is a cylindrical container 1, which is only partially shown. Arranged in the lower part of the container 1 is an annular bottom 2, on the upper surface of which a refractory cladding 3 is arranged. In the middle part of the parts 2 and 3 there is an outlet 4. The piece-shaped industry, which may be internal, e.g. tory or lignite, is located in the inner space of the container 1 Over the refractory cover 3. The combustion chamber is located Over the outlet 4.

Det genom klockans 6 dubbelvaggar bildade rummet 8 tjanar som tillfOrselledning f Or forbranningsluften. Klockans 6 undre kant 10 bestammer i forhallande till briinslematerialet ett pa bransle tomt rum 11, vars lutning bestarnmes av branslets rasvinkel och blir ungefar en rotationsyta 12. I klockans undre parti finnas ett visst antal utblasningsdyser, i utforingsexemplet visas tolv stycken vilka stä i fOrbindelse med det inre av rummet 8 kring klockan 6. Nio av dessa utblasningsdyser 13 luta nedat samt arotangentiellt anordnade, sa att den ur dem kommande luften bestryker lutningens 12 yta i en virvlande luftstr8m, och begransar forbranningen till lutningens yta. Sedan lutningen bestrukits, gar forbranningsgaserna uppat genom en kanal 9, ut ur kloekan 6 och vi-dare ut genom kanalen 7, exempelvis till en varmepanna, som skall varmas. Tre utblasningsdyser 14, vilkas axlar aro riktade nedat och ligga i ett plan, vilket gar ungefar genom klockans axel, aro anordnade for att sakra fOrbranningen i rummets 11 undre parti, genom att tillfora forbranningsluft dit. In the middle of the container 1, above the outlet 4, a conical, double-rocked bell or hood 6 is arranged, which in its upper part extends laterally in a channel 7. The space 8 formed by the double-rocker of the bell 6 serves as a supply line for the combustion air. The lower edge 10 of the bell 6, in relation to the fuel material, has an empty space 11 in the branch, the slope of which is determined by the angle of rotation of the branch and becomes approximately a rotational surface 12. In the lower part of the bell there are a certain number of exhaust nozzles. the interior of the room 8 around 6 o'clock. Nine of these exhaust nozzles 13 are inclined downwards and arranged arotangentially, so that the air coming out of them coats the surface of the inclination 12 in a swirling air flow, and limits the combustion to the surface of the inclination. After the slope has been coated, the combustion gases ascended through a channel 9, out of the claw 6 and further out through the channel 7, for example to a boiler, which is to be heated. Three exhaust nozzles 14, the shafts of which are directed downwards and lie in a plane passing approximately through the axis of the bell, are arranged to secure the combustion in the lower part of the space 11, by supplying combustion air there.

En mantel 15 är anordnad pa ringa avstand 2— — Iran behallarevaggen 1 Iran bekladnaden 3. En luftintagsledning 16 tillfor i tangentiell riktning forbranningsluft till undre delen av det ringformiga mellanrum 17, som bildas emellan de hada vaggarna 1 och 15. En mellanyagg 18, vilken är anordnad over klockans -6 undre del och i rummets 17 inre, utbreder sig langs en bage av 180° och tvingar den i rummet 17 strommande luften att stromma omkring behallarens 1 vagg, innan den nar rummet 8. A jacket 15 is arranged at a small distance 2— - Iran container cradle 1 Iran clad 3. An air intake duct 16 supplies combustion air in the tangential direction to the lower part of the annular space 17, which is formed between the had cradles 1 and 15. An intermediate cradle 18, which is arranged over the lower part of the bell -6 and in the interior of the room 17, spreads along a bag of 180 ° and forces the air flowing in the room 17 to flow around the cradle of the container 1, before it reaches the room 8.

Den ovre icke visade delen av behallaren 1 har en mellanvagg, liknande vaggen 18, och en lufttillfOrselledning, liknande ledningen 16, vilket farhindrar, att luften -Mores direkt till rummet 8, utan att cirkulera kring behallarens 1 vagg. Kammaren, som bildas av de hada yaggarna 1 och 15, upptager det genom forbranningsmaterialet utstralande varmet och leder det ater till forbranningsrummet. En varmeisolation 19 är anordnad kring kanalens 7 yttersta ande. Om den till forbranningsrummet strommande luften endast utstrommar genom dyserna 13 och 14, kunna forbranningsgaserna aven innehalla en -viss del CO. For att forbranna CO aro anordnade extra utblasningsdyser 20, vilka tillfOra luft direkt fran rummet 8 till gasuttagskanalen. Dessa extra luftintagsoppningar aro anordnade radiellt i klockans 6 inre och i ett plan nagot over klockans 6 undre parti. The upper part of the container 1 not shown has an intermediate cradle, similar to the cradle 18, and an air supply duct, similar to the duct 16, which prevents the air from flowing directly to the room 8, without circulating around the cradle of the container 1. The chamber, which is formed by the hot yags 1 and 15, absorbs the heat radiating through the combustion material and leads it back to the combustion chamber. A thermal insulation 19 is arranged around the outermost spirit of the duct 7. If the air flowing to the combustion chamber only flows out through the nozzles 13 and 14, the combustion gases may also contain a certain amount of CO. In order to burn CO, additional exhaust nozzles 20 are provided, which supply air directly from the space 8 to the gas outlet duct. These additional air intake openings are arranged radially in the interior of the bell 6 and in a plane slightly above the lower part of the bell 6.

Plattans 21 Owe yta Ar anordnad svagt konisk och har radiella flansar 26. Plattans 21 svangningar aro till for att fortvarigt avlagsna askan, som faller ned i den undre delen av apparaten. Ett lutande ror 27, som stracker sig utanfor apparaten in I klockan 6, Sr avsett for att igangsatta apparaten, d. v. s. for antandning av forbranningsmaterialet, vilket ager rum, nar man genom raret 27 beskickar rummet 11 med tandmaterial, t. ex. papper, tra eller brinnande kol. Roret 27 Iran lufttatt tillslutas medelst ett med en fixeranordning 29 forsett lock 28. Reiret har Ifimpligen ett ovalt tvarsnitt, stallt pa hogkant for att icke stora branslets nedglidande i behallarens 1 inre. A bar plate 21 arranged slightly below the outlet 4 is mounted on a vertical shaft 22 and is provided by means of a connecting rod 23 and rod 25 fixed to the plate by a bait 24 and a rod 25 which swings slightly. The upper surface of the plate 21 is arranged slightly conical and has radial flanges 26. The oscillations of the plate 21 are to permanently remove the ash which falls into the lower part of the apparatus. An inclined tube 27, which extends outside the apparatus at 6 o'clock, is intended to start the apparatus, i.e. for ignition of the combustion material, which acts as a space when the chamber 11 is charged with the chamber 11 with dental material, e.g. paper, wood or burning coal. The pipe 27 Iran aerated is closed by means of a lid 28 provided with a fixing device 29. The nest has, if necessary, an oval cross-section, placed on a vertical edge so that the large industry does not slide down into the interior of the container 1.

Den i fig. 3 och 4 visade utfOringsformen skiljer sig frau den ovan beskrivna genom klockans 6 konstruktion, som beskrives nedan. Gasklockans 6 yttre vagg 30 har i sitt nedre parti en ring 31, -Olken tjanar som stod far den klockan bildande kroppen 32. Kroppen 32, som kan utforas av gjutjarn eller eldfast material, har formen av en stympad kon med en ansluten cylindrisk del, 'ml-ken inmynnar i ledningens 7 inloppsande. Vid kroppens 32 undre ande aro anordnade utat riktade, lutande vingar 33, -vilka tjana till att dels centrera kroppen 32 mot vaggen 30, I dels giva en virvelstromning at forbranningsluften, vilken strammar frail ringrummet 8 ut pa ytan 12. The embodiment shown in Figs. 3 and 4 differs from that described above by the construction of the bell 6, which is described below. The outer cradle 30 of the gas bell 6 has in its lower part a ring 31, which serves as the body forming the bell 32. The body 32, which can be made of cast iron or refractory material, has the shape of a truncated cone with a connected cylindrical part, 'ml-ken opens into the inlet of line 7. At the lower end of the body 32 are arranged outwardly directed inclined wings 33, which serve to center the body 32 against the cradle 30, and to give a vortex flow to the combustion air, which flows from the annulus 8 to the surface 12.

I sitt undre parti har kroppen 32 inat kloc'tan riktade utblfisningsrannor 34, vilka er- satta utblasningsdyserna 13 och 14 i utfo- ringsformen enligt fig. 1 och 2. Dessa utblasningsrannor biIda uttagsoppningar, genom vilka luften kan komma fran rummet 8 till rummet 11, vane ranna 34 Sr anordnad melIan tva. lutande vingar 33 och ar sjalv lutande far att befordra luftens virvelbildning. I mitten av varje ranna kan anordnas en liknande, lutande vinge for att ytterligare be-f ordra virvelbildningar. In its lower part, the body 32 has inwardly clockwise directed exhaust chutes 34, which replace the exhaust nozzles 13 and 14 in the embodiment according to Figs. 1 and 2. These exhaust chutes form outlet openings, through which the air can come from the room 8 to the room 11. , vane ranna 34 Sr arranged melIan tva. inclined wings 33 and are themselves inclined to promote the vortex formation of the air. In the middle of each groove a similar, inclined wing can be arranged to further promote vortex formations.

I de beskrivna apparaterna, emedan forbranningsluften bestryker endast ytan av brfinslets rutschplan utan att tranga djupt in I dess massa, alstras en till denna yta begransad och i det narmaste fullkomlig forbranning till CO,. Det ar viktigt att marka, att de beskrivna apparaterna, trots sitt utseende, icke 5ro generatorer. De aro till en viss grad det motsatta, ty i en generator strommar luften genom fOrbranningsmaterialet, vilket ar I overskott och reducerar alstrad CO, till brannbar CO, under del i den beskrivna apparaten den i overskott varande forbranningsluften bestryker ytan pa forbranningsmaterialet och endast strommar mellan de pa ytan varande materialstyckena, sa att alstrad CO„ icke reduceras och i rnotsats, om det andock alstras CO denna genast oxideras av luftOverskottet. Man ser att det i motsats till en gas-generator (eller masugn) fir fritua om en apparat, dar ett luftoverskott astadkommer en maximal oxidation, da daremot i genaratorn ett bransleoverskott alstrar en maximal reducering. In the apparatus described, since the combustion air only coats the surface of the sliding plane of the fuel without penetrating deep into its mass, a combustion limited to this surface and almost complete combustion to CO 2 is generated. It is important to note that the devices described, despite their appearance, are not generators. They are to some extent the opposite, because in a generator the air flows through the combustion material, which is in excess and reduces generated CO, to combustible CO, during part of the described apparatus the excess combustion air coats the surface of the combustion material and flows only between the pieces of material present on the surface, so that generated CO 2 is not reduced and in use, if CO is generated, it is immediately oxidized by the excess air. It can be seen that, in contrast to a gas generator (or blast furnace), an apparatus is released, where an excess of air produces a maximum oxidation, whereas in the generator a surplus of industry generates a maximum reduction.

Far forbranningen tillfores den beskrivna apparaten medelst icke visade medel antingen tryekluft eller sugluft. I senare fallet alstras stromningen genom en flakt, som fir placerad medstroms i Gasuttagskanalen. Before the combustion is supplied to the described apparatus by means of means not shown, either compressed air or suction air. In the latter case, the flow is generated by a flake, which is placed co-current in the gas outlet duct.
