Abstract

The burner does not use premixing process and air is blown past guide profiles which have transverse outlets for fuel, this reduces pressure loss due to flow resistance in the burner and it represents a simple means for controlling flame length and temperature and generates a stable frame. The fuel oil or gas is pumped into stream-lined profiles (2) which have lateral outlets (3). The fuel stream emerges into the air stram and a turbulent mixture is formed on the flame side. The flame is stabilised by the streamlined profiles. The fuel serves also as a coolant for these profiles.

Description

Brenner mit Einleitkörper Die Erfindung betrifft einen Brenner ohne Vormischung,bei dem die Zuführung der Luft mittels Luftgebläse,die Zuführung des Brennstoffes (1 oder Gas) über einen oder mehrere EinleitZörper erfolgt,die quer zur Luftstromungsrichtung angeordnet sind und seitliche Cffnungen besitzen.Burner with inlet body The invention relates to a burner without Premixing, in which the air is supplied by means of an air blower, the Fuel (1 or gas) takes place via one or more inlet bodies, which transversely are arranged to the air flow direction and have side openings.

Der Zweck eines Brenners ist die Vermischung von Luft und Brennstoff,Steuerung der Flammenlänge und Flammentemperatur,Erzielung eines guten Ausbrandes und Stabilisierung der Flamme.The purpose of a burner is to mix air and fuel, control the flame length and flame temperature, achieving good burnout and stabilization the flame.

Hmerfür sind bereits eine große Anzahl verschiedener Brenner konstruiert und gebaut worden.A large number of different burners have already been designed for this purpose and been built.

Bei den bekannten Brennerarten verursacht die Vermischung von Luft und Brennstoff einen hohen Druckverlust durch Strömungswidersband.Außerdem erfordert die Beeinflussung von nlammenlänge und Flammentemperatur einen großen Aufwand.In the known types of burners causes the mixing of air and fuel has a high pressure loss due to flow restriction. Also requires influencing the length of the flame and the temperature of the flame requires a great deal of effort.

Der Erfindung liegt die Aufgabe zugrunde,den Druckverlust durch Strömungswiderstand im Brenner gering zu halten und Flammenlänge und damit Flammentemperatur auf einfache Weise zu beeinflussen sowie eine stabile Flamme zu erzeugen.The invention is based on the object of reducing the pressure loss due to flow resistance to keep the flame length and thus flame temperature low in the burner Way to influence as well as to create a stable flame.

Die Aufgabe wird erfindungsgemäß dadurch gelöst,daß die Luftzuführung zu einem Spalt verengt wird,in den ein ganz oder teilweise stromlinienförmiger Einleitkörper eingebaut wird, der über quer zur Luftströmung angeordnete Auslässe den Brennstoff der Luft zumischt.i)ie Sinleittörper bewirken flammenseitig eine Verwirbelung der Brennmittel und eine Stabilisierung der Flamme,da sie als Staukörper im Luftstrom wirken.The object is achieved according to the invention in that the air supply is narrowed to a gap into which a whole or partly more streamlined Inlet body is installed, which is arranged via outlets arranged transversely to the air flow the fuel is mixed in with the air Swirling of the fuel and a stabilization of the flame, as they act as a damming body act in the air flow.

Die theoretische Anleitung für diese Lösung gibt das Gesetz von Bernoulli,nach dem der quer zur Strömungsrichtung wirkende Druck (statischer Druck) dort am geringsten ist,wo die Strömungsgeschwindigkeit am größten ist.Das ist in den kleinsten Querschnitten der Leitungen der Fall.Daher ist es zweckmäßig beim Luftgebläsebrenner die Brennstoffauslässe an der engsten Stelle der Luft zuführung anzuordnen.The theoretical guidance for this solution is given by Bernoulli's law where the pressure acting across the direction of flow (static pressure) is lowest there is where the flow velocity is greatest. That is in the smallest cross-sections It is therefore advisable to use the fuel outlets on forced-air burners to be arranged at the narrowest point of the air supply.

In der Erfindung wird die Luftzuführung zu einem Spalt verengt und durch Einleitkörper verkleinert.Ähnlich wie beim Flügel eines Plugzeuges umströnt die Luftden Einleitkörper und saugt hierbei aus den Auslässen den Brennstoff heraus.In the invention, the air supply is narrowed to a gap and reduced in size by inlet bodies, similar to the flow around the wing of a plug tool the air enters the inlet body and sucks the fuel out of the outlets.

Für Brenner mit größeren Wärmeleistungen werden mehrere Einlegt, körper in der Luftzuführung angeordnet.Der Brennstoffstrom wird bereits vor dem Brenner in mehrere Teilströme aufgeteilt.For burners with larger heat outputs, several insert bodies are required arranged in the air supply. The fuel flow is already in front of the burner divided into several partial flows.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß bei guter Vermischung der Druckverlust der Luft gering ist,für den Brennstoff sogar eine Saugwirkung eintritt.The advantages achieved with the invention are in particular: that with good mixing the pressure loss of the air is low for the fuel even a suction occurs.

Die aus den Auslässen abgesaugte Brennstoffmenge vergrößert sich mit der Luftgeschwindigkeit.Außerdem kann durch die Form zs Einleitkörpers die Flammenlänge und Flammentemperatur auf einfache Weise beeinflut werden und eine stabile Flamme erzeugt werden.The amount of fuel sucked out of the outlets also increases The shape of the inlet body also allows the flame length and flame temperature be influenced in a simple way and a stable flame can be generated.

Dem Brenner strömt Luft durch die spaltartige Luft zuführung I und Brennstoff durch die Brennstoffzuführung 4 zu.Die Luft umströmt den Einleitkörper 2 und saugt hierbei Brennstoff aus den Auslässen 3 heraus.An die spaltartige Luftzuführung I schließt sich flammenseitig eine konische Erweiterung an.The burner air flows through the gap-like air supply I and Fuel through the fuel feed 4. The air flows around the inlet body 2 and sucks fuel out of the outlets 3 to the gap-like air supply I is followed by a conical enlargement on the flame side.

Besitzt der Brenner mehrere Einleitkörper so wenden deren Auslasse gegeneinander versetzt angeordnet (Figur 6).Auf der Flammenseite des Einleitkörpers erfolgt durch Verwirbelung eine Vermischung der Brennmittel,deren Grad durch die Form des Einleitkörpers bestimmt wird.If the burner has several inlet bodies, turn their outlets Staggered against each other (Figure 6). On the flame side of the inlet body swirl causes a mixing of the fuel, the degree of which is determined by the Shape of the inlet body is determined.
