Description
Foreliggende oppfinnelse angår en anordning ved et fyrsted, omfattende et flamrør og et aksialt etter dette anordnet etterforbrenningsrom, der en brenner er montert i den ende av flamrøret som vender fra etterforbrenningsrommet, og en innsnevret passaje er utformet mellom flamrøret og etterforbrenningsrommet , hvorved denne passasje er utformet i en veggdel som avgrenser den indre ende i flamrøret, idet den flate i veggdelen som vender mot flamrøret er traktformet i retning mot passasjen. The present invention relates to a device at a fire place, comprising a flame pipe and an axially arranged afterburner chamber, where a burner is mounted at the end of the flame pipe facing the afterburner chamber, and a narrowed passage is formed between the flame pipe and the afterburner chamber, whereby this passage is designed in a wall part that delimits the inner end of the flame tube, the surface of the wall part facing the flame tube being funnel-shaped in the direction towards the passage.
I kjeler av denne type kan det oppnås meget gode forbrennings-resultater. Formålet med den foreliggende oppfinnelse er.å forenkle utførelsen, og å skape forutsetninger for en ytterligere forbedret forbrenning. In boilers of this type, very good combustion results can be achieved. The purpose of the present invention is to simplify the execution, and to create the conditions for a further improved combustion.
Det som kjennetegner oppfinnelsen er at det i den traktformede flate i veggdelen er anordnet et antall spor som er åpne mot flamrøret og er rettet tangensialt mot en tenkt innskrevet sirkel i passasjen. What characterizes the invention is that a number of grooves are arranged in the funnel-shaped surface in the wall part which are open to the flame tube and are directed tangentially towards an imaginary inscribed circle in the passage.
Veggdelen er fortrinnsvis fremstilt som et element av ildfast-material som kan innmonteres i flamrøret, og sporene i veggdelen er fortrinnsvis utformet med tverrsnittsflater som avtar i retning mot passasjen. The wall part is preferably produced as an element of refractory material which can be installed in the flame tube, and the grooves in the wall part are preferably designed with cross-sectional surfaces that decrease in the direction towards the passage.
Oppfinnelsen skal i det følgende beskrives under henvisning The invention shall be described below by reference
til de vedføyde tegninger, der to the attached drawings, there
Fig 1 viser et vertikalsnitt gjennom en dampkjel utstyrt Fig 1 shows a vertical section through an equipped steam boiler
med et fyrsted i henhold til oppfinnelsen, og with a principality according to the invention, and
Fig.2 viser endeveggen i flamrøret sett innenfra. Fig.2 shows the end wall of the flame tube seen from the inside.
Den viste kjel er av i og for seg kjent type, og omfatter The boiler shown is of a known type in and of itself, and includes
en øvre, sylindrisk del og et undre etterforbrenningskammer 11. Sentralt i den øvre delen finnes et flamrør 12 med en brenner 13 montert i den øvre ende. Flamrørets undre ende er innsnevret ved hjelp av et innsatslegeme 14 av ildfast material og som er utstyrt med en utløpspassasje 15. an upper, cylindrical part and a lower afterburning chamber 11. Centrally in the upper part there is a flame tube 12 with a burner 13 mounted at the upper end. The lower end of the flame tube is narrowed by means of an insert body 14 of refractory material which is equipped with an outlet passage 15.
De deler av flammen som har strøket langs veggene i flamrøret 12, og derved er nedkjølt slik at forbrenningen ikke har vært fullstendig, tvinges ved hjelp av formen av den øvre flate 16 The parts of the flame which have traveled along the walls of the flame tube 12, and thereby cooled so that the combustion has not been complete, are forced by means of the shape of the upper surface 16
på innsatselementet 14, hvilken flate 16 forløper på skrå fra veggen og inn mot passasjen 15, ut i selve kjerneflammen og oppvarmes derved kraftig, samt blandes med den øvrige gass, .slik at det skjer en effektiv sluttforbrenning i etterforbrenningsrommet 11. on the insert element 14, which surface 16 extends obliquely from the wall towards the passage 15, out into the core flame itself and is thereby heated strongly, as well as mixed with the other gas, so that an efficient final combustion takes place in the afterburner chamber 11.
Den øvre sylindriske delen 10 inneholder et stort antall The upper cylindrical part 10 contains a large number
rørgassrør oppdelt i to ringformede grupper. En indre gruppe 18 av disse forløper mellom etterforbrenningsrommet 11 og et øvre vendekammer 19, og en ytre gruppe 2 0 av røkrør forløper fra vendekammeret til et undre oppsamlingskammer 21 som er tilsluttet en ikke vist skorsten. Antall røkrør i hver gruppe er slik valgt at gassens strømningshastighet, til tross for nedkjølingen, holdes i det vesentlige konstant. pipe gas pipes divided into two annular groups. An inner group 18 of these extends between the afterburning chamber 11 and an upper turning chamber 19, and an outer group 20 of smoke pipes extends from the turning chamber to a lower collecting chamber 21 which is connected to a chimney not shown. The number of flue pipes in each group is chosen in such a way that the gas flow rate, despite the cooling, is kept essentially constant.
Etterforbrenningsrommet 11 avgrenses utover av en vannkappevegg The post-combustion chamber 11 is bounded outwards by a water jacket wall
22 som er tilsluttet den øvre delen 10, mellom de to gruppene av røkrør 18, 20. Bunnen 23 i etterforbrenningsrommet er her utført av ildfast material, men kan ved større enheter, eller ved høyt belastede kjeler, utføres vannkjølt. 22 which is connected to the upper part 10, between the two groups of smoke pipes 18, 20. The bottom 23 in the afterburner is here made of refractory material, but can be made water-cooled in the case of larger units, or in the case of highly loaded boilers.
Kjelens damprom 24 er anordnet inne i den sylindriske beholderen 10, og omgir således flamrørets øvre del. Normalt vannivå er antydet ved 25. The boiler's steam room 24 is arranged inside the cylindrical container 10, and thus surrounds the upper part of the flame tube. Normal water level is indicated at 25.
Kjeler av den ovenfor beskrevne type er kjent, og disse har Boilers of the type described above are known, and these have
en helt akseptabel forbrenningsvirkningsgrad. Innsnevringen ved flamrørets utløp er dannet av platematerial på flamrøret, henholdsvis i den undre endevegg i delen 10. Av hensyn til <iet her meget høyt varmebelastede parti er det tilstrebet en effektiv vannkjøling. Denne motvirker i en viss grad tendensen til øket temperatur i de gasser som har strømmet nedover langs flam-rørets vegger. For å forbedre blandingen av de utstrømmende gassene og skape turbulens i etterforbrenningsrommet 11, er det foreslått anordnet særskikte styreorganer i passasjen 15. Begge disse forholdsregler fordyrer kjelkonstruksjonen. a completely acceptable combustion efficiency. The narrowing at the outlet of the flame tube is formed by plate material on the flame tube, respectively in the lower end wall in section 10. In consideration of the very high heat-loaded part here, effective water cooling is sought. This counteracts to a certain extent the tendency to increased temperature in the gases that have flowed down along the walls of the flame tube. In order to improve the mixing of the flowing gases and create turbulence in the afterburner 11, it is proposed to arrange special control devices in the passage 15. Both of these precautions make the boiler construction more expensive.
I henhold til den foreliggende oppfinnelse utføres flamrøret som en enkel, sylindrisk mantel, hvilken lett kan tilkobles den undre endevegg. I flamrørets undre ende innsettes i stedet et element av kjeramisk material som danner endeveggen 14 og avgrenser passasjen 15. Avhengig av kjelens størrelse kan de. tt» e •element utformes i ett stykke, eller lages på stedet av passende formede stener, eller eventuelt støpes i en form. According to the present invention, the flame tube is made as a simple, cylindrical mantle, which can easily be connected to the lower end wall. In the lower end of the flame tube, an element of ceramic material is inserted instead, which forms the end wall 14 and delimits the passage 15. Depending on the size of the boiler, they can. tt» e •element is designed in one piece, or made on site from suitably shaped stones, or possibly cast in a mould.
Et slik kjeramisk element tåler meget høye temperaturer uten Such a ceramic element can withstand very high temperatures without it
å måtte kjøles, og det er velkjent at kjeramiske innsatser av liknende type skaper gode forutsetninger for en effektiv forbrenning. to have to be cooled, and it is well known that ceramic inserts of a similar type create good conditions for efficient combustion.
Det tilstrebes å forbedre forbrenningsresultatet ved å skape Efforts are made to improve the combustion result by creating
en kraftig turbulens. Styreplater som settes inn i dette høyt varmebelastede område blir raskt ødelagt, og en fra begynnelsen god virkning vil litt etter litt avta. a strong turbulence. Guide plates that are inserted in this highly heat-stressed area are quickly destroyed, and an initially good effect will gradually diminish.
I stedet for slike løse styreorganer utstyres den traktformede flaten 16 med et antall spor 26 som er åpne mot flamrøret. Disse spor er rettet tangensialt i forhold til en tenkt Instead of such loose control means, the funnel-shaped surface 16 is equipped with a number of grooves 26 which are open to the flame tube. These tracks are directed tangentially in relation to an imaginary one
sirkel 27 innskrevet i passasjen 15. circle 27 inscribed in passage 15.
Disse spor vil følgelig motta en del av de strømmende gasser, og avbøyer disse og styrer de inn mot passasjen. For å øke hastigheten i disse delstrømmer utføres sporene med avtagende tverrsnittsflate i retning fra flamrørets mantelvegg mot passasjen 15. These tracks will consequently receive part of the flowing gases, and deflect these and direct them towards the passage. In order to increase the speed in these partial flows, the grooves are made with a decreasing cross-sectional area in the direction from the mantle wall of the flame tube towards the passage 15.
Retningen for en del av gasstrømmen bestemmes således allerede foran passasjen, og det er gassens trykk mot endeveggen som gir den nødvendige kraft. Delstrømmene treffer hovedstrømmen inne i selve passasjen, og kan der bevirke en kraftig turbulens. The direction of part of the gas flow is thus already determined before the passage, and it is the pressure of the gas against the end wall that provides the necessary force. The partial currents hit the main current inside the passage itself, and can cause a strong turbulence there.
Tegningen viser fire spor 26, men det er åpenbart at antall spor vil avhenge av størrelsen av selve elementet. The drawing shows four slots 26, but it is obvious that the number of slots will depend on the size of the element itself.
