Description

Die Güte der Verbrennung ist von der Zerstäubung des Brennstoffes, die Feinheit der Zerstäubung wiederum von der Austrittsgeschwindigkeit des Brennstoffes aus der Düse abhängig. Es ist also im Interesse einer gleichmäßig guten Verbrennung nötig, die Austrittsgeschwindigkeit des Brennstoffes nahezu konstant zu halten. Die Änderung der Brennstoffmengen bei Belastungsänderungen muß also durch Änderung des Strömungsquerschnittes erfolgen. Gemäß der Erfindung wird bei einem ölzerstäubungsbrenner, bei dem die tangentialen Austrittsöffnungen durch ein axial verschiebbares Abschlußorgan geregelt werden, die Austrittsöffnungen der im Brennergehäuse liegenden Öl:zuführungskanäle durch treppenstufenförmig nach dem Austritt sich verbreiternde tangentiale Ausmündungen gebildet, deren Weite durch einen in einer zylindrischen Bohrung des Brennergehäuses axial verschiebbaren Kolbenschieber bekannter Art eingestellt werden kann.The quality of the combustion depends on the atomization of the fuel, the fineness of the atomization, in turn, depends on the exit speed of the fuel depends on the nozzle. So it is in the interest of an evenly good combustion necessary to keep the exit speed of the fuel almost constant. The change in the amount of fuel with changes in load must therefore be changed of the flow cross-section. According to the invention, in an oil atomization burner, in which the tangential outlet openings through an axially displaceable closure member are regulated, the outlet openings of the oil in the burner housing: supply channels through step-shaped tangential openings widening after the exit formed, the width of which is formed in a cylindrical bore in the burner housing axially displaceable piston valve known type can be adjusted.

Auf einfache Weise wird dadurch ein Ölzerstäubungsbrenner geschaffen, der sich nicht so leicht verstopft, also sehr betriebssicher arbeitet und eine gute Regelung der zu zerstäubenden Ölmengen bewirkt.In this way, an atomizing oil burner is created in a simple manner, which does not get clogged so easily, so it works very reliably and has a good one Control of the amount of oil to be atomized causes.

In der Zeichnung ist die Erfindung beispielsweise veranschaulicht, und zwar in Fig. r in einem senkrechten Längsschnitt und in Fig. 2 in einem Querschnitt nach Linie A-B der Fig. i. Wie ersichtlich, besteht der Ölbrenner aus einem Gehäuse c mit zylindrischer Bohrung, an die sich die kegelförmige Düsenöffnung anschließt. In dem Geh'.use c befinden sich vier Längsbohrungen e, von denen tangential die Austrittskanäle a für das unter Druck zugeführte C51 in das Innere der Bohrung ausmünden. An diesen tangentialen Austrittskanälen a. gleitet ein an einer Stange d gehaltener Kolben b entlang, so daß die Austrittskanäle a ent weder ganz oder teilweise überdeckt werden können. Die Austrittskanäle a können zur Ermöglichung einer Feinregehung in axialer Richtung mit veränderlicher Breite, also z. B. treppenstufenartig, ausgebildet sein.In the drawing, the invention is illustrated by way of example, namely in FIG. R in a vertical longitudinal section and in FIG. 2 in a cross section along line AB of FIG. As can be seen, the oil burner consists of a housing c with a cylindrical bore to which the conical nozzle opening is connected. In the housing c there are four longitudinal bores e, of which the outlet channels a for the pressurized C51 open tangentially into the interior of the bore. At these tangential outlet channels a. slides a d held at a piston rod along b, so that the outlet channels a ent neither can be covered entirely or partially. The outlet channels a can to enable a Feinregehung in the axial direction with a variable width, so z. B. step-like, be formed.
