Description

Atmosphärischer Gasbrenner für beliebige Leistungen mit beliebiger Flammenrichtung, insbesondere horizontalbrennend Mit der Erfindung ist ein atmosphärischer Gasbrenner entwickelt worden, der den bekannten Coanda-Effekt ausnützt. Dieser Effekt ermöglicht es, mit hohem Wirkungsgrad einen Sekundärstrom mitzureißen. Atmospheric gas burner for any power with any Direction of flame, especially burning horizontally With the invention is an atmospheric one Gas burner has been developed that uses the well-known Coanda effect. This effect makes it possible to entrain a secondary current with a high degree of efficiency.

Gas, das aus der Leistung 1 kommend in den Ringraum 2 eintritt, verläßt diesen wieder durch den Ringspalt 3. Der bekannte Coanda-Effekt besteht nun einmal in der Haftneigung des Gasstromes an der Ringwand 4. Er wird also umgelenkt und fließt mit großer Geschwindigkeit als Grenzschicht in Pfeilrichtung 5 entlang der Oberfläche des Ringes. Zweitens aber reißt er Luft aus dem freien Raum in den Ring und durch diesen hindurch. Durch das Zusammentreffen der beiden Medien entsteht eine gute Vermischung.Gas coming from the power 1 into the annular space 2 leaves this again through the annular gap 3. The well-known Coanda effect just exists in the tendency of the gas flow to adhere to the ring wall 4. It is thus deflected and flows at high speed as a boundary layer in the direction of arrow 5 along the Surface of the ring. Second, however, it tears air from the free space into the ring and through this. The meeting of the two media creates a good mix.

Es lag nahe, diesen Effekt nicht nur für die Luftströme gleicher oder verschiedener Temperaturen auszunützen, sondern auch als Gas- Luftmischeinrichtung für einen Gasbrenner. Der hohe Wirkungsgrad des Coanda-Effektes erlaubt es, einen Gasbrenner ohne Gebläse selbst für hohe Leistungen zu bauen, der seine Verbrennungsluft selbst ansaugt. Dies ist Gegenstand der beschriebenen Erfindung.It was obvious that this effect was not only the same or for the air currents different temperatures, but also as a gas-air mixing device for a gas burner. The high efficiency of the Coanda effect allows one Build your own gas burner without a fan for high performance using its combustion air self sucks. This is the subject of the invention described.

Um eine vollkommene Mischung von Gas und Luft zu erzielen, wurde der Ring verlängert, so daß ein in Brennrichtung konisches Rohr 6 entstand.In order to achieve a perfect mixture of gas and air, the Ring lengthened so that a tube 6 which is conical in the direction of combustion was created.

Ohne Rücksicht auf die Eigenschaften verschiedener Gasarten ist es möglich, an der Mündung des Rohres eine Gasflamme mit einwandfreiem Brennverhalten zu erzielen, die keinerlei Rückschlagneigung hat, Dasselbe Prinzip ist auch in einer Anordnung nach Figo 2 angewandt, bei der das Gas nicht von außen, sondern von innen (2) zugeführt wird und der Coanda-Effekt an dem Ringspalt 3 und der gewölbten Außenfläche des Körpers 4 entsteht. Die Spaltbreite wird durch mechanische Anordnung sowohl bei Prinzip nach Fig. 1, als auch Prinzip nachFigç2 verstallbar gemacht.Regardless of the properties of different types of gas, it is possible, a gas flame with perfect burning behavior at the mouth of the tube to achieve that has no tendency to kickback, the same principle is also in one Arrangement according to Figo 2 applied, in which the gas is not from the outside, but from the inside (2) is supplied and the Coanda effect on the annular gap 3 and the curved outer surface of the body 4 arises. The gap width is determined by mechanical arrangement both made adjustable with the principle according to Fig. 1, as well as the principle according to Fig.2.

Da sich die Düse im Betrieb erwärmt, wurde um sie ein Kühlmantel angeordnet, durch den das vom Netz zuströmende Gas zufließt, bevor es zur Verbrennung in der Düse gelangt. Die Zündung des Brenners kann elektrisch oder durch Handzündung zoB. mit einer Lunte erfolgen.Since the nozzle heats up during operation, a cooling jacket was placed around it, through which the gas flowing in from the network flows in before it is burned in the Nozzle. The burner can be ignited electrically or by hand, for example. done with a fuse.

Für automatische Brenner ist eine Flammenüberwachung vorgesehen, die thermoelektrisch, elektronisch-optisch, mit Jonisationsstab, oder mit einem anderen bekannten Verfahren erreicht wird0 Auch die Ausstattung des Brenners mit Ventilen, die über das Steuergerät und über Impulsgeber, z Thermostaten, Pressostaten u.a. zum- automatischen Betrieb betätigt werden, ist bekannt.A flame monitor is provided for automatic burners, which thermoelectrically, electronically-optically, with a ionizing rod, or with another known processes is achieved 0 Equipping the burner with valves, via the control unit and via pulse generators, e.g. thermostats, pressostats, etc. to be operated for automatic operation is known.

Eine weitere Verwendung des Coanda-Effektes ist bei Gebläsebrennern für Gas oder Öl und bei kombinierten Gas-Ölbrennern gegeben, wo der Brennr-mündungskopf entsprechend ausgestaltet wird. Dadurch ist der Brenner-Mündungskopf eines solchen Brenners ohne Änderung für alle Gasarten geeignet.Another use of the Coanda effect is with fan burners for gas or oil and with combined gas-oil burners, where the combustion nozzle head is designed accordingly. The burner muzzle head is one of these Burner suitable for all types of gas without modification.
