Description

Die Erfindung bezieht sich auf einen Zerstäuber-Ölbrenner mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to an atomizer oil burner with the features of the preamble of claim 1.

Druckzerstäuber-Ölbrenner der hier infrage stehenden Art sind solche, bei denen das Spiralgehäuse des Gebläses in der Druckzone praktisch tangential in das Flammrohr übergeht, das die Stirnplatte durchtritt. Das bedeutet, daß die Welle des Gebläserades sich parallel zur Ebene des Durchtrittsbereiches der Stirnplatte erstreckt und daß der Antriebsmotor mit seiner Abtriebswelle an der einen Seite koaxial zur Welle des Gebläserades angeordnet ist, während sich die Antriebswelle der Ölpumpe koaxial auf der anderen axialen Seite des Spiralgehäuses befindet. Der axiale Eingang und damit das Luftregelgehäuse befindet sich dabei in der Regel zwischen dem Gebläserad und der Ölpumpe. Dies hat den besonderen Vorteil, daß die Ölpumpe von dem Antriebsmotor räumlich verhältnismäßig weit getrennt angeordnet werden kann, so daß bei einem Defekt der Ölpumpe kein Öl in den Antriebsmotor gelangt, was diesen außer Betrieb setzen würde. Es muß also lediglich in einem Defektfalle die Ölpumpe ausgewechselt werden, der Antriebsmotor wird nicht in Mitleidenschaft gezogen.Pressure atomizer oil burners of the type in question here are those in which the spiral housing of the fan in the pressure zone merges practically tangentially into the flame tube which passes through the end plate. This means that the shaft of the impeller extends parallel to the plane of the passage area of the end plate and that the drive motor with its output shaft is arranged on one side coaxially to the shaft of the impeller, while the drive shaft of the oil pump is coaxial on the other axial side of the volute casing located. The axial input and thus the air control housing is usually located between the fan wheel and the oil pump. This has the particular advantage that the oil pump can be arranged relatively far apart from the drive motor, so that if the oil pump fails, no oil gets into the drive motor, which would put it out of operation. It is therefore only necessary to replace the oil pump in the event of a defect, the drive motor is not affected.

Bei bekannten Ölbrennern dieser Bauart mündet der Eingangsbereich des Luftregelgehäuses frei in den Raum, der von der Abdeckhaube, die an die Stirnplatte angeschlossen ist, umschlossen wird. In der Stirnplatte ist ein Luftansaugkanal vorgesehen, so daß bei Betrieb Luft von außen her in den von der Abdeckhaube umschlossenen Innenraum nachströmen kann, wenn das Gebläse durch das Luftregelgehäuse aus diesem Innenraum Luft ansaugt und dem Flammrohr zuführt.In known oil burners of this type, the entrance area of the air control housing opens freely into the space which is enclosed by the cover hood which is connected to the end plate. An air intake duct is provided in the end plate, so that, during operation, air can flow in from outside into the interior enclosed by the cover hood when the fan sucks in air from this interior through the air control housing and supplies it to the flame tube.

Zur Anpassung an die jeweiligen Betriebsverhältnisse wird der Ölbrenner - naturgemäß bei abgenommener Abdeckhaube - eingestellt, beispielsweise durch Einstellung der Luftklappe, des Düsenstocks und dergleichen. Wird danach die Abdeckhaube aufgesetzt, so ergibt sich ein anderes Widerstandsverhalten für die Luftzufuhr, da während der Einstellung bei abgenommener Abdeckhaube der Eingangsbereich des Luftregelgehäuses in den freien Raum mündete, während bei aufgesetzter Abdeckhaube nunmehr die Luft aus dem abgedeckten Innenraum unter Nachströmen durch den Luftansaugkanal angesogen werden muß. Dadurch ergibt sich ein bestimmter Luftmangel im Vergleich zu den Luftförderbedingungen während der Einstellung bei abgenommener Abdeckhaube.To adapt to the respective operating conditions, the oil burner is adjusted - naturally with the cover removed - for example by adjusting the air flap, the nozzle assembly and the like. If the cover is then put on, there is a different resistance behavior for the Air supply, since during the adjustment with the cover removed, the entrance area of the air control housing opened into the free space, while with the cover attached, the air from the covered interior now has to be sucked in underflow through the air intake duct. This results in a certain lack of air compared to the air delivery conditions during adjustment with the cover removed.

Der Erfindung liegt die Aufgabe zugrunde, den Zerstäuber-Ölbrenner der eingangs genannten Art derart auszugestalten, daß die Luftzuführbedingungen für das Gebläse während der Einstellung des Brenners dieselben sind wie diejenigen während des Betriebs.The invention has for its object to design the atomizer oil burner of the type mentioned in such a way that the air supply conditions for the fan during the setting of the burner are the same as those during operation.

Ausgehend von einem Zerstäuber-Ölbrenner mit den Merkmalen des Oberbegriffes des Anspruches 1 wird diese Aufgabe erfindungsgemäß durch dessen kennzeichnende Merkmale gelöst..Starting from an atomizer oil burner with the features of the preamble of claim 1, this object is achieved according to the invention by its characterizing features.

Erfindungsgemäß wird das Luftregelgehäuse mit seinem Eingangsbereich an eine Öffnung in der Stirnplatte angeschlossen, an welche sich außenseitig der Luftansaugkanal anschließt. Damit wird zunächst erreicht, daß die von dem Gebläse angesaugte Luft nicht aus dem von der Haube umgebenen Innenraum entnommen wird, in den sie durch den wie auch immer gestalteten Luftansaugkanal im Stirnplattenbereich mit der Folge nachströmt, daß die Luftzufuhrverhältnisse zu dem Gebläse bei abgenommener Abdeckhaube anders sind als bei aufgesetzter Haube, sondern die Luft wird unabhängig von der Abdeckhaube immer der Aussenumgebung des Brenners entnommen. Die Geräuschentwicklung durch das Gebläse bzw. die angesaugte Luft soll jedoch möglichst gering sein, weshalb der Absaugkanal sich über eine möglichst groß bemessene Strecke hinweg an der Außenseite der Stirnplatte erstreckt und schalldämmend ausgebildet ist. Bei einem Brennertyp der hier infrage stehenden Art wird dies insbesondere dadurch erreicht, daß der Luftansaugkanal von der unterhalb des Flammrohres und demgegenüber zur einen Seitenberandung der Stirnplatte hin versetzt angeordneten Öffnung ausgehend unterhalb des Flammrohres auf die entgegengesetzte Seitenberandung der Stirnplatte hin geführt ist. Dabei wird in besonders bevorzugter Ausführung der Luftansaugkanal zwischen der Außenoberfläche der Stirnplatte und einem deckelförmigen Kanalgehäuse gebildet, das insbesondere langgestreckt schalenförmig ausgebildet ist und an seinem die Öffnung übergreifenden stirnseitigen Ende geschlossen und an dem gegenüberliegenden stirnseitigen Ende als Lufteinlaßöffnung ausgebildet ist.According to the invention, the air control housing is connected with its input area to an opening in the end plate, to which the air intake duct connects on the outside. This initially ensures that the air sucked in by the blower is not removed from the interior space surrounded by the hood, into which it flows through the air intake duct in the end plate area, with the result that the air supply conditions to the blower are different when the cover is removed are as with the hood attached, but the air is always taken from the outside of the burner regardless of the hood. However, the noise generated by the blower or the intake air should be as low as possible, which is why the suction channel extends over the largest possible distance on the outside of the end plate and is designed to be sound-absorbing. In the case of a burner type of the type in question here, this is achieved in particular in that the air intake duct extends from the one below the flame tube and on the other hand to the side bar edge of the end plate is arranged offset starting from below the flame tube to the opposite side edge of the end plate. In a particularly preferred embodiment, the air intake duct is formed between the outer surface of the end plate and a cover-shaped duct housing, which is in particular elongated, cup-shaped and is closed at its front end overlapping the opening and is designed as an air inlet opening at the opposite end.

Die schalldämmende Ausgestaltung des Luftansaugkanales wird bevorzugt durch eine Auskleidung, insbesondere aus einem Polyurethanschaum, gebi Idet. Diese Auskleidung, die vorzugsweise auf die Innenwandungen des schalenförmigen Kanalgehäuses beschränkt ist, kann auf diese Innenwandungen aufgeschäumt werden. In bevorzugter Ausführung wird jedoch diese Auskleidung als Isolierkörper ausgebildet, der in das Kanalgehäuse dessen Innenwandungen abdeckend eingesetzt wird. Grundsätzlich kann der lsolierkörper durch Verkleben an den Innenwandungen befestigt werden; doch ist dies nicht erforderlich, da bei Aufbringen des Kanalgehäuses auf die Außenseite der Stirnplatte - insbesondere durch von innen her zugängliche Verschraubung - die Auskleidung auch ohne Festlegung in ihrer Lage innerhalb des Kanalgehäuses gehalten wird.The sound-absorbing design of the air intake duct is preferably provided by a lining, in particular made of a polyurethane foam. This lining, which is preferably limited to the inner walls of the shell-shaped channel housing, can be foamed onto these inner walls. In a preferred embodiment, however, this lining is designed as an insulating body which is inserted into the channel housing, covering its inner walls. In principle, the insulating body can be attached to the inner walls by gluing; however, this is not necessary since when the duct housing is applied to the outside of the end plate - in particular by means of a screw connection accessible from the inside - the lining is held in its position within the duct housing without being fixed.

In besonders bevorzugter Ausführung wird der langgestreckte Ansaugkanal längsgeteilt ausgebildet, und zwar mit wenigstens einem Längssteg, der vorzugsweise durch den Isolierkörper gebildet wird. Auf diese Weise erreicht man ein für die Schalldämmung vorteilhaft großes Verhältnis zwischen Länge des Einzelkanales und dessen Breite bzw. Durchmesser. Der Schall wird in diesen Kanälen reflektiert und bei den Reflektionen an der schalldämmenden Auskleidung entsprechend gedämpft. Es können zwei oder mehrere solcher paralleler Einzelkanäle gebildet werden, die sich über einen Teil der Länge des Ansaugkanales erstrecken, beispielsweise beginnend kurz hinter der Lufteinlaßöffnung und endend vor dem Übergang zur Öffnung in der Stirnplatte, an die sich innenseitig der Eingangsbereich des Luftregelgehäuses anschließt. In diesem Übergangsbereich, dort also, wo die Luft umgelenkt wird, befindet sich in der von der Umlenkung betroffenen Innenwandung ein besonderes Schallschutzpolster, beispielsweise durch eine besonders dicke Ausbildung der Polyurethanschicht, das aufgrund seiner Nachgiebigkeit bzw. geringen Reflektionseigenschaft als Schallwellensumpf angesprochen werden kann.In a particularly preferred embodiment, the elongated intake duct is formed lengthways, with at least one longitudinal web, which is preferably formed by the insulating body. In this way, a ratio between the length of the individual channel and its width or diameter, which is advantageous for sound insulation, is achieved. The sound is reflected in these channels and attenuated accordingly in the reflections on the sound-absorbing lining. Two or more such parallel individual ducts can be formed, which extend over part of the length of the intake duct, for example starting shortly behind the air inlet opening and ending before the transition to the opening in the end plate, to which the input region of the air control housing is located on the inside closes. In this transition area, i.e. where the air is redirected, there is a special soundproofing pad in the inner wall affected by the redirection, for example due to a particularly thick design of the polyurethane layer, which can be addressed as a sound wave sump due to its resilience or low reflection properties.

Der lsolierkörper aus Polyurethanschaum kann offenporig oder mit einer dünnen Oberflächenhaut ausgebildet sein.The insulating body made of polyurethane foam can be open-pore or with a thin surface skin.

In weiterhin bevorzugter Ausführung ist der Innenraum zwischen der Stirnplatte und der Abdeckhaube durch eine weitere, in der Stirnplatte vorgesehene Öffnung belüftet, und zwar insbesondere derart, daß diese Öffnung in den Anfangsbereich des Luftansaugkanales mündet. Im Inneren des Raumes zwischen der Stirnplatte und der Abdeckung bildet sich erwärmte Luft, die ausgetauscht werden muß, beispielsweise schon wegen elektronischer Steuerelemente und anderer wärmeempfindlicher Teile. Durch die angesaugte Luft wird über die weitere Öffnung der Luftinhalt des Innenraumes ausgetauscht. Dies kann man noch wirksamer gestalten, indem man in Längsrichtung des Luftansaugkanales gesehen zwei Öffnungen hintereinander anordnet, von denen die weiter in den Luftansaugkanal hinein verlegte Öffnung vorzugsweise im Bereich einer Verengung des Luftansaugkanales liegt, beispielsweise im Bereich des oder der Längsstege, die die Einzelkanäle schaffen. Auf diese zweite Öffnung wird dann ein erhöhter Sog ausgeübt, wodurch erreicht wird, daß in die von der Einlaßöffnung des Luftansaugkanales her gesehen erste Öffnung Frischluft eingesogen wird, während die erwärmte Luft des Innenraumes durch die zweite Öffnung austritt und so einen vorgewärmten Luftanteil für die Zuführung zu dem Flammrohr bildet.In a further preferred embodiment, the interior between the end plate and the cover hood is ventilated through a further opening provided in the end plate, in particular in such a way that this opening opens into the initial region of the air intake duct. In the interior of the space between the end plate and the cover, heated air forms which has to be exchanged, for example because of electronic controls and other heat-sensitive parts. The air content of the interior is exchanged through the further opening due to the sucked-in air. This can be made even more effective by arranging two openings one behind the other, as seen in the longitudinal direction of the air intake duct, of which the opening further into the air intake duct is preferably in the area of a narrowing of the air intake duct, for example in the region of the longitudinal web or webs that create the individual ducts . An increased suction is then exerted on this second opening, with the result that fresh air is sucked into the first opening seen from the inlet opening of the air intake duct, while the heated air of the interior exits through the second opening and thus a preheated air portion for the supply to the flame tube.

Mit der erfindungsgemäßen Ausbildung des infrage stehenden Ölbrenners wird somit erreicht, daß die Luftverhältnisse bei abgenommener und aufgesetzter Abdeckhaube für den Verbrennungsvorgang identisch sind. Damit sind die bei abgenommener Abdeckhaube vorgenommenen Einstellungen für den Normalbetrieb bei aufgesetzter Haube unverändert gültig und richtig. Zugleich wird durch den Anschluß an den schallgedämpften Luftansaugkanal dafür Sorge getragen, daß die durch das Ansaugen der Luft sowohl wie durch den Gebläsebetrieb hervorgerufenen Geräusche wirksam gedämpft werden. Dies wird gerade durch den unmittelbaren Anschluß des Luftregelgehäuses an den Luftansaugkanal mit ermöglicht.With the inventive design of the oil burner in question it is thus achieved that the air conditions for the combustion process are identical when the cover is removed and attached. This means that the settings made for normal operation when the cover is removed with the hood attached, it remains valid and correct. At the same time, the connection to the silenced air intake duct ensures that the noise caused by the intake of air as well as by the fan operation is effectively attenuated. This is made possible by the direct connection of the air control housing to the air intake duct.

On the outside of the end plate 2, the flame head 3 is provided at the end of a flame tube 4, which is connected to the fan denoted overall by 5 or forms an integral part of the spiral housing 6 of the fan. The fan 5 is arranged on the inside of the end plate 2, so that the flame tube 4 passes through the end plate 2. The flame tube 4 connects practically tangentially to the discharge area of the spiral housing 6 of the blower 5 and is oriented with respect to its axis approximately perpendicular to the plane of the end plate in this area, as can be seen in FIGS. 1 and 2.

Wie insbesondere Figur 2 zeigt, ist das Gebläserad 7 axial zwischen dem Antriebsmotor 8 und der Ölpumpe 9 angeordnet, und zwar derart, daß die Abtriebswelle des Antriebsmotors 8, die Antriebswelle des Gebläserades 7 und die Antriebswelle der Ölpumpe 9 auf einer gemeinsamen Achse 10 lregen, die srch parallel zur Ebene der Stirnplatte 2 erstreckt. Die Stirnplatte 2 ist im vorliegenden Beispiel hinsichtlich ihres Querschnittes gestuft ausgebildet, d.h. sie ist im Bereich der Durchführung des Flammrohres 4 nach vorne versetzt und in dem darunter liegenden Bereich entsprechend zurückliegend angeordnet. Wenn hier von der Ebene der Stirnplatte 2 die Rede ist, dann hinsichtlich der Erstreckung des jeweiligen gemeinten Teilbereiches etwa senkrecht zur Längsachse des Flammrohres 4.As particularly shown in Figure 2, the impeller 7 is arranged axially between the drive motor 8 and the oil pump 9, in such a way that the output shaft of the drive motor 8, the drive shaft of the impeller 7 and the drive shaft of the oil pump 9 on a common axis 10, which extends parallel to the plane of the end plate 2. In the present example, the end plate 2 is of stepped design in terms of its cross section, that is to say it is offset to the front in the area where the flame tube 4 is passed and is correspondingly arranged in the area below. If the plane of the end plate 2 is mentioned here, then it is approximately perpendicular to the longitudinal axis of the flame tube 4 with respect to the extension of the respective intended partial area.

Zwischen dem Gebläserad 7 und der Ölpumpe 9 ist der axiale Zuführbereich des insgesamt mit 11 bezeichneten Luftregelgehäuses angeordnet. Dieses Luftregetgehäuse 11 weist einen Eingangsbereich 12 auf, der eine Luftregelklappe 13 beherbergt, die die Einstellung der jeweils geförderten Luftmenge ermöglicht. Dieser Eingangsbereich 12 des Luftregelgehäuses 11 mündet bei den herkömmlichen Brennern der geschilderten Art in den Innenraum 15, der zwischen der Stirnplatte 2 und einer an diese angeschlossenen Abdeckhaube 14 gebildet ist. Die Abdeckhaube 14 umschließt somit das Gebläse 5, den Antriebsmotor 8, die Ölpumpe 9 und das Luftregelgehäuse 11 gemeinsam mit nicht dargestellten Steuer- und Regeleinrichtungen und dergleichen, wie sie von diesem Brennertyp her bekannt sind. AI die vorgenannten Teile sind direkt oder indirekt an der Innenseite 16 der Stirnplatte 2 angeordnet bzw. befestigt.Between the fan wheel 7 and the oil pump 9, the axial feed area of the air control housing, designated overall by 11, is arranged. This air control housing 11 has an input area 12, which houses an air control flap 13, which enables the adjustment of the amount of air conveyed in each case. In the conventional burners of the type described, this input area 12 of the air control housing 11 opens into the interior 15, which is formed between the end plate 2 and a cover 14 connected to it. The cover 14 thus encloses the fan 5, the drive motor 8, the oil pump 9 and the air control housing 11 together with control and regulating devices and the like, not shown, as are known from this type of burner. AI the aforementioned parts are arranged or attached directly or indirectly to the inside 16 of the end plate 2.

Läßt man den Eingangsbereich 12 des Luftregelgehäuses 11 einfach in den Innenraum 15 münden, so muß man natürlich dafür sorgen, daß in diesen Innenraum 15 Luft nachströmen kann, was man bisher durch einen wie auch immer gestalteten Luftansaugkanal im Bereich der Stirnplatte bewerkstelligt hat. Nachteilig war dabei, daß die Strömungsverhältnisse bei abgenommener Haube 14 und damit der Einstellung des Brenners andere waren als bei aufgesetzter Abdeckhaube.If you simply let the entrance area 12 of the air control housing 11 open into the interior 15, one must of course make sure that air can flow into this interior 15, which has been accomplished up to now by an air intake duct in the area of the end plate. The disadvantage here was that the flow conditions when the hood 14 was removed and thus the setting of the burner were different than when the hood was attached.

Um dies zu vermeiden, ist der Eingangsbereich 12 des Luftregelgehäuses 11 unmittelbar dicht an eine Öffnung 18 angeschlossen, die in der Stirnplatte 2 vorgesehen ist, wie dies die Figuren erkennen lassen. An der Außenseite 17 der Stirnplatte 2 ist ein insgesamt mit 19 bezeichneter Luftansaugkanal vorgesehen, der in seinem Endbereich dicht an die Öffnung 18 anschließt.In order to avoid this, the input area 12 of the air control housing 11 is directly connected to an opening 18 which is provided in the end plate 2, as can be seen in the figures. On the outside 17 of the end plate 2 there is an air intake duct, designated overall by 19, which adjoins the opening 18 in its end region.

Der Luftansaugkanal 19 wird zwischen der Außenseite 17 der Stirnplatte 2 und dem Inneren eines Kanalgehäuses 20 gebildet, das sich schalenförmig von der einen Seitenberandung 21 der Stirnplatte 2, zu der hin gegenüber der Mitte versetzt die Öffnung 18' angeordnet ist, zu der entgegengesetzten Seitenberandung 22 hin erstreckt. Fig. 1 läßt erkennen, daß das schalenförmige Kanalgehäuse 20 unterhalb des Flammrohres 4 bzw. des entsprechend nach vorn vorgerückten Abschnittes der Stirnplatte 2 verläuft, in Betriebsstellung also etwa horizontal. Mit seinem in Nähe der Seitenberandung 21 der Stirnplatte 2 gelegenen stirnseitigen Ende 23 übergreift das Kanalgehäuse 20 die Öffnung 18 völlig, während an dem gegenüberliegenden Ende des Kanalgehäuses 20 eine Lufteinlaßöffnung 24 vorgesehen ist, die ein Schutzgitter 25 aufweist, das aus parallel verlaufenden Rippen gebildet ist. Zwischen der Lufteinlaßöffnung 24 und der Öffnung 18, die den Luftansaugkanal 19 mit dem Luftregelgehäuse 11 verbindet, entsteht somit ein langgestreckter Kanal, der sich vertikal unterhalb des Flammrohres 4 über einen Großteil der Breite der Stirnplatte 2 erstreckt.The air intake duct 19 is formed between the outside 17 of the end plate 2 and the inside of a duct housing 20, which is in the form of a shell from the one side edge 21 of the end plate 2, towards which the opening 18 ′ is offset toward the center, to the opposite side edge 22 extends. Fig. 1 shows that the shell-shaped channel housing 20 runs below the flame tube 4 or the correspondingly advanced portion of the end plate 2, in the operating position approximately horizontally. With its end 23 located near the side edge 21 of the end plate 2, the channel housing 20 completely engages over the opening 18, while at the opposite end of the channel housing 20 an air inlet opening 24 is provided, which has a protective grid 25 which is formed from parallel ribs . Between the air inlet opening 24 and the opening 18, which connects the air intake duct 19 to the air control housing 11, an elongated duct is thus created, which extends vertically below the flame tube 4 over a large part of the width of the end plate 2.

Der Luftansaugkanal 19 ist mit Hilfe einer Auskleidung 26 schallgedämmt ausgebildet, die aus einem Schallisolierkörper 27 besteht, der lediglich die Innenwandungen des Kanalgehäuses 20 abdeckt, nicht dagegen die Außenseite 17 der Stirnplatte 2. Damit ist es möglich, die Auskleidung 26 einstückig auszubilden, ohne Gefahr zu laufen, daß sich zwischen der Auskleidung und oer Außenseite 17 der Stirnplatte 2 ein Nebenkanal bzw. ein Schlitz bildet. Die Reflektionen der Außenseite 17 der Stirnplatte 2 treffen in jedem Falle auf Teile des Isolierkörpers 27, wodurch eine wirksame Schallabsorption erreicht wird. Dabei können ohne weiteres mehrere Reflektionen auftreten, die von Mal zu Mal aufgrund des lsolierwerkstoffes, vorzugsweise ein Polyurethanschaum, gedämpft werden. Dieser Polyurthanschaum oder ein ähnliches Material kann Öffnungen aufweisen, die als Resonatoren dienen, es wird eine sehr gute Schalldämmung aber auch bei einer dünnhäutigen Oberfläche des lsoliermateriales erzielt.The air intake duct 19 is designed to be sound-insulated with the aid of a lining 26, which consists of a sound insulating body 27 which only covers the inner walls of the duct housing 20, but not the outside 17 of the end plate 2. This makes it possible to form the lining 26 in one piece without danger to run that a secondary channel or a slot is formed between the lining and the outer surface 17 of the end plate 2. The reflections of the outside 17 of the end plate 2 meet parts of the insulating body 27 where is achieved through effective sound absorption. Several reflections can easily occur, which are dampened from time to time due to the insulating material, preferably a polyurethane foam. This polyurethane foam or a similar material can have openings that serve as resonators, but very good sound insulation is achieved even with a thin-skinned surface of the insulating material.

Wie Fig. 1 erkennen läßt, ist der Hohlraum des Luftansaugkanales 19 in zwei Einzelkanäle 29 und 30 unterteilt, und zwar durch einen Längssteg 28, der an dem Schalisolierkörper 27 einstückig ausgebildet ist. Anstelle dieses einen Längssteges 28 können auch zwei oder mehr solcher Stege vorgesehen sein mit der Folge, daß entsprechend viele Einzelkanäle gebildet werden. Allerdings muß beachtet werden, daß der Strömungswiderstand des Luftansaugkanales dadurch nicht ungebührlich beeinträchtigt wird.As can be seen in FIG. 1, the cavity of the air intake duct 19 is divided into two individual ducts 29 and 30, namely by a longitudinal web 28 which is formed in one piece on the formwork insulating body 27. Instead of this one longitudinal web 28, two or more such webs can also be provided, with the result that a correspondingly large number of individual channels are formed. However, it must be ensured that the flow resistance of the air intake duct is not unduly affected.

Die Unterteilung des Ansaugkanales in Einzelkanäle hat zur Folge, daß diese im Verhältnis zu Ihrem Durchmesser entsprechend lang ausgebildet sind, wodurch sich die Reflektionsabstände entsprechend verkürzen und damit die Dämpfung bzw. Dämmung des Schalles verbessern. Der Längssteg 28 erstreckt sich im vorliegenden Beispiel von einem kurz hinter der Lufteinlaßöffnung 24 gelegenen Eingangsbereich des Luftansaugkanales 19 bis zum Beginn der Öffnung 18. Im Bereich des Überganges zwischen den längsgestreckten Einzelkanälen 29 und 30 hin zu der Öffnung 18 muß die angesogene Luft umgelenkt werden. In diesem Bereich ist der Schallisollerkörper 27 mit einer Verdickung versehen, die als Schallenergiesumpf 31 bezeichnet werden kann. Die hier auftreffenden Luftgeräusche werden weit in die Tiefe hinein aufgenommen und absorbiert. Die damit erreichten Schalldämmungen sind ganz beträchtlich.The subdivision of the intake duct into individual ducts has the result that they are designed to be correspondingly long in relation to their diameter, as a result of which the reflection distances are shortened accordingly and thus improve the attenuation or insulation of the sound. In the present example, the longitudinal web 28 extends from an input region of the air intake duct 19 located just behind the air inlet opening 24 to the beginning of the opening 18. In the region of the transition between the elongated individual ducts 29 and 30 to the opening 18, the sucked-in air must be deflected. In this area, the sound insulation body 27 is provided with a thickening, which can be referred to as the sound energy sump 31. The air noise here is absorbed and absorbed far into the depth. The sound insulation achieved with this is very considerable.

Im Bereich des Überganges zwischen dem Eingangsbereich 12 des Luftregelgehäuses 11 und dem axialen Eingang 32 des Spiralgehäuses 6 des Gebläses ist die Innenwandung 33 des bogenförmig außen verlaufenden Umlenkabschnittes des Luftregelgehäuses 11 etwa viertelkreisförmig ausgebildet, und zwar in der Draufsicht von oben, wie dies Fig. 2 erkennen läßt. Der Mittelpunkt des Viertelkreisbogens liegt etwa im Schnittbereich zwischen der Achse 10 und der Ebene der axialen Eingangsöffnung 32 des Spiralgehäuses 6. Durch diese Ausformung erreicht man sehr günstige Strömungsverhältnisse, was wiederum der Schalldämmung zugute kommt und insgesamt die Leistungsbilanz des Brenners verbessert.In the area of the transition between the input area 12 of the air control housing 11 and the axial input 32 of the spiral housing 6 of the fan, the inner wall 33 of the is curved the outer deflecting portion of the air control housing 11 is approximately quarter-circular, in plan view from above, as can be seen in FIG. 2. The center point of the quarter-circle arc lies approximately in the intersection between the axis 10 and the plane of the axial inlet opening 32 of the spiral housing 6. This configuration achieves very favorable flow conditions, which in turn benefits the sound insulation and improves the overall performance of the burner.

Wie aus Fig. 2 ersichtlich ist, befindet sich unterhalb des Flammrohres 4 und demgegenüber zur Seitenberandung 22 der Stirnplatte 2 verschoben, also quersymmetrisch etwa gegenüberliegend der Öffnung 18, eine weitere Öffnung 34, die den Eingangsbereich des Luftansaugkanales 19 mit dem Innenraum 15 verbindet, der zwischen der Innenseite 16 der Stirnplatte 2 und der Abdeckhaube 14 gebildet ist. Dieser Innenraum erwärmt sich während des Betriebes, so daß eine Entlüftung bereits aus diesem Grunde erforderlich erscheint. Quer zu der Öffnung 34 verläuft der Strom der angesaugten Luft durch den Ansaugkanal 19, so daß ein gewisser Sog auf den Innenraum 15 ausgeübt wird. Dies führt dazu daß erwärmte Luft aus dem Innenraum 15 mitgenommen und dem Gebläse zugeführt wird, während ein Teil der durch die Lufteinlaßöffnung 24 des Luftansaugkanales 19 eintretende Außenluft in den Innenraum 15 gelangen kann. Durch in Längsrichtung des Luftansaugkanales versetzte Anordnung von zwei oder mehreren Öffnungen kann man die Austauschwirkung auf den Innenraum 15 noch fördern, wobei man sich die Tatsache zunutze machen kann, daß die Sogwirkung im Bereich der Einzelkanäle durch höhere Strömungsgeschwindigkeit ansteigt.As can be seen from FIG. 2, there is another opening 34 below the flame tube 4 and, in contrast, displaced to the side edge 22 of the end plate 2, that is to say transversely symmetrically approximately opposite the opening 18, which connects the input region of the air intake duct 19 to the interior 15, is formed between the inside 16 of the end plate 2 and the cover 14. This interior heats up during operation, so that ventilation appears to be necessary for this reason alone. The flow of the sucked-in air runs transversely to the opening 34 through the suction duct 19, so that a certain suction is exerted on the interior 15. This leads to the fact that heated air is taken from the interior 15 and fed to the blower, while part of the outside air entering through the air inlet opening 24 of the air intake duct 19 can get into the interior 15. By arranging two or more openings offset in the longitudinal direction of the air intake duct, the exchange effect on the interior 15 can still be promoted, whereby one can take advantage of the fact that the suction effect in the region of the individual ducts increases due to the higher flow velocity.
