Abstract

The burner has a gap (3) between two heatable walls (2,4), of which one wall (2) rotates. The other wall (4) is heated by electrical heating elements (6), and by the burner flame when the burner is running. An oil vapour-air mixture is formed, in combination with air which flows through an air gap (14) at the periphery of the rotating wall (2), directly at the outlet (7) of the gap (3) and burns at the outlet of burner nozzles (8'). <IMAGE>

Description

Stufenlos regelbarer Ölgebläsebrenner Infinitely variable forced draft oil burner

Die Erfindung betrifft einen stufenlos regelbaren Ölgebläsebrenner nach Patentanspruch 1 der Patentanmeldung P 33 14 326.9.The invention relates to a continuously variable forced draft oil burner according to claim 1 of patent application P 33 14 326.9.

In dem Spalt zwischen den benachbarten Wänden verdampft das Ö1, um am Austritt mit Luft vermischt zu werden und zu verbrennen. Dabei war gemäß der Hauptanmeldung vorgeschlagen worden, mindestens eine Wand beheizbar zu machen und die Beheizung durch elektrische Heizelemente und/oder durch die Brennerflamme erfolgen zu lassen. In den Ausführungsbeispielen war jeweils der rückwärtigen Brennraumbegrenzung die Beheizung durch die Brennerflamme zugeordnet, während die elektrischen Heizelemente an der anderen Seite des Verdampferspaltes angeordnet waren. Diese Heizelemente mußten gegen über dem dahinter liegenden Luftraum isolierend abgedichtet werden, um Wärmeverluste und ein Zurückströmen von Öldampf zu verhinder.The oil evaporates in the gap between the adjacent walls to be mixed with air at the outlet and burn. It was according to the Main application has been proposed to make at least one wall heatable and the heating is carried out by electrical heating elements and / or by the burner flame allow. In each of the exemplary embodiments, the rear limitation of the combustion chamber was in each case the heating is assigned by the burner flame, while the electrical heating elements were arranged on the other side of the evaporator gap. These heating elements had to be insulated against the air space behind it, to prevent heat loss and backflow of oil vapor.

Es soll eine noch einfachere und dennoch wirkungsvollere Konstruktion eines Ölgebläsebrenners der beschriebenen Art geschaffen werden.It is supposed to be an even simpler, yet more effective construction a forced draft oil burner of the type described can be created.

Der Ölgebläsebrenner ist gemäß der Erfindung durch die im Kennzeichen des Patentanspruches 1 genannten Merkmale gekennzeichnet, Beide Möglichkeiten zur Beheizung sind bewußt einer einzigen Wand zugeordnet, ii. zw. der feststehenden, rückwärtigen Brennraumbegrenzung. Auf diese Weise ist die Regelung der Beheizung der Verdampfungseinrichtung wesentlich einfacher möglich als bei einer abwechselnden Beheizung von einer der beiden Wände. Eine rückwärtige Isolierung zu einem hinteren Luftraum hin kann entfallen. Ein weiterer Vorteil entsteht dadurch, daß die hinter der beheizten, feststehenden Wand liegende, rotierende Wand zwangsweise an ihrem Umfang nicht abdichtet. Der dort entstehende Ringspalt wird als Luftspalt genutzt, so daß direkt am Austritt des Verdampferspaltes ein brennbares bldampf- Luft-Gemisch entsteht. Dieses wird dann Austritt von nachgeschalteten Brennerdtisen verbrannt. Es entsteht eine äußerst günstige Vermischung von Öldampf mit Luft.The forced draft oil burner according to the invention is characterized by in of claim 1 features mentioned, both ways to Heating are deliberately assigned to a single wall, ii. between the fixed, rearward Combustion chamber limitation. This is the way the scheme is the heating of the evaporation device is much easier than with a alternating heating of one of the two walls. Rear insulation to a rear air space can be omitted. Another advantage arises from that the rotating wall lying behind the heated, fixed wall forcibly does not seal on its circumference. The annular gap created there is called an air gap used, so that a combustible bldampf- Air mixture is created. This is then an outlet from the burner burner connected downstream burned. The result is an extremely favorable mixture of oil vapor with air.

Ein Zurückströmen von Öldampf wird verhindert.A backflow of oil vapor is prevented.

Die beigefügte Zeichnung stellt in einer einzigen Figur ein Ausführungsbepspiel der Erfindung dar.The attached drawing represents an exemplary embodiment in a single figure of the invention.

Eine hohle, konisch sich erweiternde Antriebswelle 1 für eine rotierende Wand 2 führt das Öl zu einem Spalt 3 zwischen dieser Wand 2 und einer feststehenden Wand 4 als hinterer Brennraumbegrenzung. Diese feststehende Wand 4 wird zunächst durch elektrische Heizelemente 6 und bei laufendem Brenner durch die Brennerflamme beheizt. Ein nicht dargestellter Thermostat übernimmt dabei die Regelung Am Austritt 7 des Spaltes 3 gelangt das verdampfte Öl mit Verbrennungsluft in Verbindung, welche einen Luftspalt 14 am Umfang der rotierenden Wand 2 durchströmt. Ein ZutUckströmen von Öldampf in den Bereich 12 hinter die rotierende Wand 2 wird verhindert. Das ampf- Luft-Gemisch tritt nach dem Durchstrdmen eines Gemisch-Kanales 10' durch Düsen 8', um zu verbrennen. Ein federbelastetes Kugelventil 13 am Eingang der konisch sich erweiternden, hohlen Antriebswelle 1 regelt den Ölzufluß zum Spalt 3.A hollow, conically widening drive shaft 1 for a rotating Wall 2 leads the oil to a gap 3 between this wall 2 and a stationary one Wall 4 as the rear limitation of the combustion chamber. This fixed wall 4 is initially by electrical heating elements 6 and by the burner flame when the burner is running heated. A thermostat, not shown, takes over the control at the outlet 7 of the gap 3, the evaporated oil comes into contact with combustion air, which flows through an air gap 14 on the circumference of the rotating wall 2. An inflow Oil vapor in the area 12 behind the rotating wall 2 is prevented. That After flowing through a mixture channel 10 ', the ampf-air mixture passes through nozzles 8 'to burn. A spring-loaded ball valve 13 at the entrance of the conical expanding, hollow drive shaft 1 regulates the flow of oil to gap 3.
