Die vorliegende Erfindung bezieht sich auf die bekannten Brenner zum Brennen von gasförmigen Brennstoffen, Sauerstoff und Luft, bei welchen die Mischung der Gase über dem Brenner kurz vor der Verbrennungszone erfolgt. Bei derartigen Brennern hat man bereits den gasförmigen Brennstoff und den Sauerstoff durch zwischen drei gleichachsig ineinandergesteckten Rohren gebildete Ringkanäle der Verbrennungsstelle zugeführt, wobei die innerhalb der Brennermündung aufeinandertreffenden ringförmigen Gasströme durch das innere, unten offene Rohr Luft ansaugen.The present invention relates to the known burners for burning gaseous Fuels, oxygen and air in which the gases are mixed above the burner just before the combustion zone. In burners of this type, the gaseous fuel and the oxygen are already equiaxed through between three nested tubes formed annular channels supplied to the combustion point, wherein the ring-shaped gas flows that meet within the burner mouth through the inner tube, which is open at the bottom, are air suck in.

Nach vorliegender Erfindung sind die drei ineinandergesteckten, als Leitungen für beide Gasarten und die Verbrennungsluft dienenden Rohre an den Mündungen derart verengt und so gerichtet, daß der gasförmige Brennstoff und der Sauerstoff in einer Kreislinie oberhalb der Brennermündung gegeneinander geführt werden, wobei sie durch den von den Rohren gebildeten mittleren Ringraum Luft ansaugen.According to the present invention, the three are nested, as lines for both Gas types and the combustion air serving pipes at the mouths so narrowed and directed so that the gaseous fuel and the oxygen in a circular line above the burner mouth against each other, with air through the central annular space formed by the tubes suck in.

Dieser sowohl für Beleuchtungs- wie auch für Heizzwecke mit gleich befriedigendem Erfolg anwendbare Brenner zeichnet sich durch große Einfachheit aus und gestattet eine äußerst intensive und gleichmäßige Mischung der Heizgase und der Verbrennungsluft, andererseits einen sparsamen Brennstoffverbrauch und weitgehendste Regelbarkeit der Gaszufuhr zwecks Bestimmung des Mischungsverhältnisses zur Erreichung der gewünschten Flammentemperatur. Es wird also mit Hilfe des Brenners nicht nur einer zu großen Zufuhr teuerer Brennstoffe vorgebeugt und dadurch der Betrieb verbilligt, sondern auch andererseits das Entstehen einer Flamme mit übermäßiger· Temperatur verhindert, die, sobald es sich um die Erhitzung von Glühkörpern für Beleuchtung handelt, ein übermäßiges Angreifen und frühzeitiges Zerstören des Glühkörpess zur Folge haben könnte.This one for both lighting and heating purposes with equally satisfactory Burner that can be used successfully is distinguished by its great simplicity and allows an extremely intensive and even mixture of hot gases and combustion air, on the other hand, economical fuel consumption and maximum controllability of the Gas supply to determine the mixing ratio to achieve the desired Flame temperature. So, with the help of the burner, it doesn't just become too large a supply Preventing expensive fuels and thereby making operation cheaper, but also, on the other hand, the formation of a flame · Excessive temperature prevents the once it comes to heating of incandescent bodies acts for lighting, could result in excessive attack and premature destruction of the incandescent body.

Der neue Brenner schafft weiter die Möglichkeit, eine einzelne Gasart, gegebenenfalls Petroleumdämpfe zu verbrennen, ohne daß die Flamme blakt oder zurückschlägt, aus dem Grunde, weil jeder Gasstrom durch einen besonderen Ringraum nach der Verbrennungsstelle geführt wird. Man kann sich sogar für den Fall, daß stark sauerstoffhaltiges Gas neben Petroleumdämpfen benutzt werden soll, aber gerade nicht zur Stelle ist, mit Petroleumdämpfen allein behelfen.The new burner further creates the ability to use a single type of gas, if necessary Burning petroleum fumes without the flame flashing or flashing back the reason, because each gas flow through a special annulus after the combustion point to be led. One can even use gas with a high oxygen content in addition to petroleum vapors should, but is not currently on the spot, manage with petroleum fumes alone.

Auf der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes beispielsweise in einem senkrechten und in einem wagerechten Schnitt dargestellt.An embodiment of the subject matter of the invention is shown in the drawing, for example shown in a vertical and in a horizontal section.

Der Brenner besteht im wesentlichen aus drei ineinandergesteckten Rohren f, n, d, die in Abständen voneinander gehalten sind und außer der mittleren Leitung b zwei Ringräume α und c bilden. Sämtliche Wege des Brenners sind derart verengt und so gerichtet, daß die einerseits durch den zylindrischen Kanal b, andererseits durch den äußeren Ringraum α zugeführten Gasarten (gasförmiger Brennstoff und Sauerstoff) über dem Brenner in einer Kreislinie aufeinanderprallen und den durch den mittleren Ringraum c zugeführten Luftstrom ansaugen. Zu diesemThe burner consists essentially of three nested tubes f, n, d, which are kept at a distance from one another and, apart from the central line b, form two annular spaces α and c . All paths of the burner are narrowed and directed in such a way that the types of gas (gaseous fuel and oxygen) supplied on the one hand through the cylindrical channel b and on the other hand through the outer annular space α collide above the burner in a circular line and the air flow supplied through the central annular space c suck in. To this

Claims

Purpose this middle annular space c is initially equipped at the upper end with a nozzle formed by inclined surfaces. The outer annular space α and the cylindrical central path b of the pipe f also form nozzles, namely ring nozzles, which are formed by a slidably attached roof piece e and by the inverted umbrella-like surface g supported by an adjustable stud bolt g1. Outwardly, the whole thing appears as a single annular nozzle. The air is supplied through the slot openings h of the central annular space c, which can be regulated if desired. The mixing of the gas streams emerging from α and b at a corresponding speed takes place just above the mouth of the burner, at which point the air sucked in through the inner annular space c also enters. Flashback of the flame is excluded, as is excessive heating and damage to the burner itself. In the exemplary embodiment of the drawing, the known mantle i is arranged above the burner and held in place by mounting brackets k. Through the tubes I and m, the gaseous fuel and the oxygen to the cylinder space b respectively. fed to the outer annulus a. As is also assumed in the drawing, the outer annular space a, which is expediently used as the largest channel for feeding the gaseous fuel, can be fed to the latter at several points (see m in FIG. 2). Conversely, the gaseous fuel can also be supplied through the inner tube b, and the oxygen through the outer annular space. In addition to the good properties generally indicated above, the burner has the further advantage that, if it is to be used with petroleum as a heating medium, the special preheating by means of a spirit flame, which is otherwise customary in the known burners of this type, is omitted because the ignition of the used second type of gas is accomplished, whereupon the supply of the latter is turned off and can only be burned further with the petroleum vapors formed as a result of the heating of the burner. 55 Patent-A ν Proverbs:
