Description
Avgassbrenner. Exhaust gas burner.
Denne oppfinnelse vedrører en avgassbrenner omfattende et forbrenningskammer med innløp og avløp for innkobling av forbrenningskammeret i en avgassledning og med innløp for inntak av primær- og sekundærluft i forbrenningskammeret, samt et i forbrenningskammeret anordnet katalyserende materiale for kontinuerlig antennelse av brennbare bestanddeler i de tilførte avgasser. This invention relates to an exhaust gas burner comprising a combustion chamber with inlet and outlet for connection of the combustion chamber in an exhaust gas line and with inlet for intake of primary and secondary air in the combustion chamber, as well as a catalytic material arranged in the combustion chamber for continuous ignition of combustible components in the supplied exhaust gases.
Oppfinnelsens hovedformål er å skaffe en avgassbrenner som kan virke kontinuerlig uten spesiell varmekilde og uten at der oppstår tilstopping som følge av faste partikler som følger med av-gassene, og som kan fremstilles med små omkostninger for å mulig-gjøre en omfattende anvendelse, såsom i motorkjøretøyer. The main purpose of the invention is to provide an exhaust gas burner which can operate continuously without a special heat source and without clogging occurring as a result of solid particles accompanying the exhaust gases, and which can be manufactured at low cost to enable a wide-ranging application, such as in motor vehicles.
Det særegne ved oppfinnelsen er en gjennombrutt turbulator som er anordnet i forbrenningskammeret i avstand fra innløpet for blandingen av luft og avgasser og som omfatter en mot innløpet rettet, ringformet, konkav vegg, og en i dennes midtdel anordnet nese som er rettet mot innløpet, samt en annen, motstående, ringformet, konkav vegg anordnet foran avgassinnløpet og konsentrisk omsluttende dette for dannelse av et ovalt formet forbrenningskammer, mellom hvis konkave endevegger gassen hvirvler frem og tilbake , og et etter den første, gjennombrutte turbulator anordnet etterforbrenningskammer, til hvilket gassene suksessivt strømmer inn gjennom den gjennombrutte turbulator. The peculiarity of the invention is a perforated turbulator which is arranged in the combustion chamber at a distance from the inlet for the mixture of air and exhaust gases and which comprises an annular, concave wall directed towards the inlet, and a nose arranged in its middle part which is directed towards the inlet, and another, opposite, ring-shaped, concave wall arranged in front of the exhaust gas inlet and concentrically surrounding this to form an oval-shaped combustion chamber, between whose concave end walls the gas swirls back and forth, and an afterburner arranged after the first, broken-through turbulator, to which the gases successively flow in through the perforated turbulator.
For en bedre forståelse vil oppfinnelsen i det følgende bli beskrevet mere detaljert under henvisning til tegningene, hvor fig. 1 er et aksialsnitt av avgassbrenneren ifølge oppfinnelsen bestemt for bruk ved motorkjøretøyer og fig. 2 viser et snitt etter linjen 2 - 2 i fig. For a better understanding, the invention will be described in more detail in the following with reference to the drawings, where fig. 1 is an axial section of the exhaust gas burner according to the invention intended for use in motor vehicles and fig. 2 shows a section along the line 2 - 2 in fig.
Den på tegningen viste utførelse omfatter en stålplate-boks 24 som danner forbrenningskammeret og har en katalyserende keramisk foring 2 5 eventuelt med en katalysator inkorporert i samme. En nese 26 er anbragt i en platemetallboks 28 som er aksialt inn-stillbar og kan fastholdes i innstilt stilling, f.eks. ved hjelp The embodiment shown in the drawing comprises a steel plate box 24 which forms the combustion chamber and has a catalytic ceramic lining 25, optionally with a catalyst incorporated therein. A nose 26 is placed in a sheet metal box 28 which is axially adjustable and can be held in an adjusted position, e.g. with help
av en skrue 27; denne boks 28 har en ring- og koppformet vegg 29 med en åpning 30 og danner en etterforbrenningssone 31, med hvilken en utløpsledning 32 er forbundet. Foringen 25 er tilgjengelig for gass i etterforbrenningssonen 31 gjennom hull 28' i boksens 28 man-tel. Til den annen endevegg 33 av boksen 24 er der festet en sy-linder 34 med en flens 35 for å forbinde sylinderen med motorens manifold 36. En skillevegg 37 mellom et avgassinnløpsrør 38 og sylinderen 34 deler sylinderen i to kammere 39 og 40, av hvilke kammeret 39 er forbundet med en sugeluftledning 41 som eventuelt of a screw 27; this box 28 has an annular and cup-shaped wall 29 with an opening 30 and forms an afterburning zone 31, with which an outlet line 32 is connected. The liner 25 is accessible to gas in the afterburning zone 31 through holes 28' in the casing 28 of the box. A cylinder 34 with a flange 35 is attached to the other end wall 33 of the box 24 to connect the cylinder to the engine's manifold 36. A partition wall 37 between an exhaust gas inlet pipe 38 and the cylinder 34 divides the cylinder into two chambers 39 and 40, of which the chamber 39 is connected to a suction air line 41 as appropriate
er utstyrt med en luftrenser; kammeret 40 er over en trykkluftled-ning 42 forbundet med en luftpumpe 43 som kan drives fra motorens aksel over en rem. To rør 44 og 45 er ført gjennom endeveggen 33 og danner sammen med røret 38 to kanaler som hver har en halvring-formet åpning 46 og 47 som fører til kamrene 39 hhv. 40. Røret 44 bærer en ring 48 som hindrer baktenning og består av en tynn is equipped with an air cleaner; the chamber 40 is connected via a compressed air line 42 to an air pump 43 which can be driven from the motor's shaft via a belt. Two pipes 44 and 45 are passed through the end wall 33 and together with the pipe 38 form two channels, each of which has a semi-ring-shaped opening 46 and 47 leading to the chambers 39 and 39 respectively. 40. The tube 44 carries a ring 48 which prevents back-ignition and consists of a thin
vegg av varmemotstand8dyktig metalltrådnetting med katalysatormateriale påført samme, eller av et tykkere legeme 49 av samme materiale som delene 25 og 26, eller av steatitt belagt eller dék- wall of heat-resistant metal wire mesh with catalyst material applied to the same, or of a thicker body 49 of the same material as parts 25 and 26, or of steatite coated or covered
ket med katalysatormateriale på en innad vendende overflate. Rørene 38, 44 og 45 kan være innbyrdes understøttet ved hjelp av aksiale ribber eller vinger 50. En gløde- eller gnistplugg 51 er anordnet i forbrenningskammerets vegg. ket with catalyst material on an inward facing surface. The tubes 38, 44 and 45 can be mutually supported by means of axial ribs or wings 50. A glow or spark plug 51 is arranged in the wall of the combustion chamber.
Ved den beskrevne utførelse av oppfinnelsen blandes av-gassen fra forbrenningsmotoren med den i forbrenningskammeret inn-førte luft og den resulterende brennbare blanding antennes til å begynne med, dvs. når motoren og åom følge derav forbrenningskammeret er kalt, ved hjelp av tennelementet (gnist- eller glødeplug-gen). Etter at forbrenning har begynt og den keramiske katalysator er blitt opphetet til den temperatur som kreves for å bevirke at forbrenningen fortsetter av seg selv under virkningen av kata-lysatoren, som kan være i en glødende tilstand, kan tennelementet frakobles. Som allerede angitt kan dette element kobles inn ved hjelp av bilens tenningsnøkkel for å bli utkoblet av et tidsrelé eller en lignende anordning en viss tid etter at det ble koblet inn. Tennelementet kan imidlertid også kobles inn og ut av en termostat som avføler temperaturen i forbrenningskammeret. In the described embodiment of the invention, the exhaust gas from the combustion engine is mixed with the air introduced into the combustion chamber and the resulting combustible mixture is initially ignited, i.e. when the engine and consequently the combustion chamber is fired, by means of the ignition element (spark or the glow plug gene). After combustion has begun and the ceramic catalyst has been heated to the temperature required to cause combustion to continue by itself under the action of the catalyst, which may be in a glowing state, the ignition element may be disconnected. As already indicated, this element can be switched on by means of the car's ignition key to be switched off by a time relay or similar device a certain time after it was switched on. However, the ignition element can also be switched on and off by a thermostat which senses the temperature in the combustion chamber.
Forbrenningen i forbrenningskammeret gjennomføres ved en torusflamme rundt turbulatorens nese på den side av samme som ven-der mot avgasstrømmen. Strømmen av gassene i forbrenningskammeret er angitt ved pilen på fig. /. En viss etterforbrenning foregår ved den viste utførelse etter at de brennende gasser har passert gjennom turbulatorens åpninger, i etterforbrenningssonen mellom turbulatoren og utløpet. Combustion in the combustion chamber is carried out by a torus flame around the nose of the turbulator on the side facing the exhaust gas flow. The flow of the gases in the combustion chamber is indicated by the arrow in fig. /. A certain afterburning takes place in the embodiment shown after the burning gases have passed through the turbulator's openings, in the afterburning zone between the turbulator and the outlet.
Den beskrevne avgassbrenner er også anvendelig i forbin-delse med kull- eller oljefyrte ovner, såsom dampkjeler, i hvilket tilfelle tennelementet kan utelates. The described exhaust gas burner is also applicable in connection with coal- or oil-fired furnaces, such as steam boilers, in which case the ignition element can be omitted.
Ikke bare avgasser fra forbrenningsmotorenes sylindre, men også karbonoksyd- eller hydrokarbonmettede gasser fra deres veivkasser kan tilføres forbrenningskammeret for avgasser. Not only exhaust gases from the cylinders of internal combustion engines, but also carbon monoxide or hydrocarbon-saturated gases from their crankcases can be supplied to the combustion chamber for exhaust gases.
For å tilveiebringe den nødvendige turbulens i forbrenningskammeret kan avgassinnløpet anordnes tangentialt i et sylin-drisk forbrenningskammer med et aksialt utløp for at luft og gass skal passere gjennom forbrenningskammeret under roterende bevegel-se på samme måte som i et syklonapparat og stryke over katalysa-toren som er anordnet som en foring i kammeret. I andre modifiser-te utførelser av oppfinnelsen kan forbrenningskammeret ha annen tverrsnittsform enn den sirkulære, f.eks. rektangulær. In order to provide the necessary turbulence in the combustion chamber, the exhaust gas inlet can be arranged tangentially in a cylindrical combustion chamber with an axial outlet so that air and gas will pass through the combustion chamber in a rotating motion in the same way as in a cyclone apparatus and sweep over the catalyst which is arranged as a liner in the chamber. In other modified embodiments of the invention, the combustion chamber can have a different cross-sectional shape than the circular one, e.g. rectangular.
