Description

Uppfinnare: S Kofink Prioritet begtird fra den 4 mars 1959 (Forbundsrepubliken Tgskland) Uppfinningen avser en spriclareanordning for med flytande bransle matade varmeag- gregat, innefattande en med brannkammaren koaxiell flakt for forbranningsluft och en spridareanordning och vid vilka branslemun- styeket och tandstiftet aro anordnade i samma mot forbranningsluftens stromningsaxel vinkelrata plan. Inventor: S Kofink Priority Begtird from 4 March 1959 (Federal Republic of Germany) The invention relates to a spray device for heating units supplied with liquid fuel, comprising a flake coaxial with combustion chamber for combustion air and a spreader device and in which same plane perpendicular to the combustion axis of the combustion air.

Vid kanda varmeaggregat av detta slag Er branslemunstycket och tandstiftet anordnade i en forkammare i brannkammarens yttre mantel. Branslet insprutas darvid med munstycket pa sad.ant salt, att det for att forga- sas och tandas traffar det intilliggande glodstiftet. Anordningar aro vidare kanda, vid vilka branslet infores i ett ruin for finfOrdelning genom forbranningsluftflakten och frau detta rum utspruta:s radiellt. In the case of heaters of this type, the fuel nozzle and the toothpick are arranged in an antechamber in the outer jacket of the fire chamber. The fuel is then injected with the nozzle on such salt that it hits the adjacent glow plug in order to gasify and ignite. Devices are further known, in which the fuel is introduced into a ruin for atomization through the combustion air and from which space is ejected radially.

Andamalet med uppfinningen Or, att forbattra dessa kanda anordningar genom att mojliggora att det genom centrifugalspridare finfardelade branslet likformigt och utan fordrajning kommer att anitandas. Enligt upp- finningen astadkommes detta genom att an- ordna branslemunstycket i en frail brannkammarens vagg foretradesvis vinkelratt mot for- branningsluftens stromningsaxel utskjutande fOrkammare saint genom att anordna en roterbar finfordelningsanordning for branslet i branslemunstyckets stralplan ph ett sadant satt, att branslestralen frau branslemunstycket i huvudsak traffar den roterbara finfordelningsanordningens periferi. The object of the invention is to improve these known devices by enabling the fuel comminuted by centrifugal diffusers to be uniformly and without distortion ignited. According to the invention, this is achieved by arranging the fuel nozzle in a frail fire chamber cradle preferably perpendicular to the combustion air flow axis projecting the chamber saint by arranging a rotatable atomizing device for the industry in the fuel nozzle radial plane of the fuel nozzle. the periphery of the rotatable atomizer.

Enligt uppfinningen Or foretradesvis forbranningsluftflaktens nay utbildat som ett organ far centrifugalfinfordelning av branslet, I Tars utsprutningsomrade tandorganet, exempelvis ett tandstift Or anordnat. According to the invention, preferably the combustion air nay is formed as a means for centrifugal distribution of the fuel, in the tars ejection area of the tooth means, for example a toothed pin Or arranged.

Genom att anordna branslemunstycket utanfor brannkammarvaggen i en farkamma- EWA kl. 24 b: 1/07; 63 c: 73 re uppnas framfor allt att detta joke blir for varmt, sh .att branslet forgasas for tidigt. By arranging the fuel nozzle outside the fire chamber cradle in a vessel chamber- EWA at 24 b: 1/07; 63 c: 73 re achieved above all that this joke gets too hot, sh .that the industry is gasified too soon.

Langden av denna forkammare och darmed avstandet av branslemunstycket frail brannkammaren beror av drifttemperaturen i brannkammaren. Det har visat sig vara lamp- ligt att anordna branslemunstycket sa, att den utsprutade branslestralen intrader i brannkammaren lodratt neat. The length of this antechamber and thus the distance of the fuel nozzle from the fire chamber depends on the operating temperature in the fire chamber. It has proved feasible to arrange the fuel nozzle so that the ejected fuel jet enters the fire chamber vertically neatly.

Spridaren enligt uppfinningen beskrives 1 anslutning till bifogade ritning. The spreader according to the invention is described in connection with the accompanying drawing.

Varmeanordningens hiilje betecknas med 1 och dess forbrannkammare med la. I holjet 1 Or en sehematiskt visad flaktmotor 2 anordnad, vars axel uppbar flakthjulet 3. Den insugna friskluften ledes i den visade utforingsformen genom en ledring 4 axiellt in i brannkammaren. Flakthjulet 3 Or f8rsett med ett lhngt mot brannkammaren riktat, cylindriskt nay 3a. Branslet insprutas frail brannkammarens och hOljets 1 ovre del in mot den framre delen av navet 3a medelst ett branslemunstyeke 5, anordnat i forkammaren lb. I utforingsexemplet Or forkamrnaren ungefOr lodratt riktad emot navets 3a axel. Mitt emot Or tandstiftet 6 anordnat. The heat of the heating device is denoted by 1 and its combustion chamber by 1a. Arranged in the housing 1 is a sehematically shown flat motor 2, the axis of which carried the flat wheel 3. The sucked-in fresh air is led in the embodiment shown through a guide ring 4 axially into the fire chamber. The flat wheel 3 Or provided with a cylindrical nay 3a directed longitudinally towards the fire chamber. The fuel is injected from the upper part of the fire chamber and the housing 1 towards the front part of the hub 3a by means of an industry nozzle 5, arranged in the antechamber 1b. In the embodiment, the front chamber is approximately vertically directed towards the axis 3a of the hub. Opposite Or toothpick 6 arranged.

Det genom branslemunstycket 5 tillfOrda branslet traffar den framre delen av navet 3a i form av en sluten strale. Derma strait delas upp pa navet, fOrgasas delvis och fortsatter delvis mot tandstiftet 6. I phsprutningsomradet ph navet 3a uppstar en tat bransledimma, vilken medfor snabb och saker tandning vid start av varmeaggregatet. Tandningsforloppet ferloper harvid radiellt in mot den bildade virvelns karna. The fuel supplied through the branch nozzle 5 strikes the front part of the hub 3a in the form of a closed jet. This strait is divided on the hub, partially gasified and continues partly towards the toothed pin 6. In the ph spraying area ph the hub 3a a dense industry fog arises, which causes rapid and things ignition when starting the heater. The course of ignition then extends radially towards the nuclei of the formed vortex.

Navets 3a framre del kan Oven ph kant saft forses med skovlar eller liknande, vilka astadkomma en finfordelning av branslet. Vid det visade utforingsexemplet Oro tvh skivringar 2— — 3b och 3c anordnade ph navet 3a, vilka forhindra, att den genom det av navet 3a och ledringen 4 bildade munstyoket strommande forbranningsluften drar med sig det ph. navet insprutade brdnslet. Den. i forbrannkammaren la antanda bransleblandningen ledes genom flamringen 7 in i efterbrannkammaren id och intrader Over steget le i det yttre ringformade rummet if. Hdr sker varmeovergangen till den frail flakten 2a Indian varmevaxlingsytorna i brannkammaren lc och det ringformade rummets If vagg ledda friskluften. The front part of the hub 3a can be fitted with shovels or the like. In the exemplary embodiment shown, the ph hub 3a is arranged on two disc rings 2-3-3b and 3c, which prevent the combustion air flowing through the nozzle flowing through the hub 3a and the guide ring 4 from entraining the ph. the hub injected the fuel. The. in the pre-combustion chamber 1a, the igniting fuel mixture is led through the flame ring 7 into the post-combustion chamber id and enters above step le in the outer annular space if. Hdr takes place the heat transfer to the frail flat 2a Indian heat exchange surfaces in the fire chamber lc and the ring-shaped room If the cradle led fresh air.
