Description

Gegenstand der Erfindung ist ein Brenner ins besondere für den automatischen Betrieb, der in Industrieöfen verwendet wird. Bekannt sind Brenner vieler Firmen, z.B. BLOOM - USA, FULMINA - BRD, HEGWEIN - BRD oder UNITHERM - Österreich, die für ihren automatischen Betrieb in zusätzliche Anlagen für die Entzündung, Flammendetektion und Kontrolle der Verbrennungsqualität ausgestattet sind. Diese Anlagen sind in ihrer Bauweise mit dem Brenner nicht integriert; sie sind teure Zusatzausstattungen des Brenners.The invention relates to a burner, in particular for automatic operation, which is used in industrial furnaces. Burners from many companies are known, e.g. BLOOM - USA, FULMINA - FRG, HEGWEIN - FRG or UNITHERM - Austria, which are equipped for their automatic operation in additional systems for ignition, flame detection and control of combustion quality. The construction of these systems is not integrated with the burner; they are expensive additional equipment for the burner.

Anzündungsbrenner - d.h. die Anzünder, in denen Gas und die Brennluft im Brennerkörper vor der Brennkammer gemischt werden und die Zündung und die Flammendetektion die sich durch gemeinsame Elektroden vollziehen, die sich längsseits der ganzen Brennerlänge bis zum Flammenbereich an ihrer Mündung erstrecken, sind auch bekannt.Ignition burner - i.e. the igniters in which gas and the combustion air are mixed in the burner body in front of the combustion chamber and the ignition and flame detection which are carried out by common electrodes which extend along the entire length of the burner to the flame region at their mouth are also known.

Solch eine Konstruktion hat viele Nachteile, es besteht u.a. die Gefahr der Gemischentzündung vor der Austrittsdüse im Brennerkörper. Dies beschränkt die Länge der Brennerkonstruktion, erfordert aber die Anwendung einer speziellen Isolationskeramik und macht den Bau von Brennern mit größerer Wärmeleistung unmöglich. Diese Brenner sind besonders für die Entzündung großer Gasüberschüsse in Fackeln nützlich.Such a construction has many disadvantages, among other things there is a risk of mixture ignition before Outlet nozzle in the burner body. This limits the length of the burner construction, but requires the use of special insulation ceramics and makes it impossible to build burners with a higher heat output. These burners are particularly useful for igniting large excess gas in flares.

Das Wesen der Erfindung besteht darin, den Brennerköper mit einem Rohrstutzen der Luft- und Brennstoffzufuhr elektrisch zu isolieren. Die Brennkammer geht in die Brennstoffmündung von einem zylindrischen Element über, das koaxial im Brennerkörper durch einen elektrischen Isolator befestigt wird; dieser befindet sich im hinteren, kühlen Teil des Brenners. An das zylindrische Mittelelement wird eine elektrische Klemme angeschlossen, die, verbunden mit dem Speisungs-­Regulier- und Steuerungssystem durch die Isolationsdurchführung aus dem äußeren Teil des Brennerkörpers herausgeführt wird.The essence of the invention is to electrically isolate the burner body with a pipe socket of the air and fuel supply. The combustion chamber merges into the fuel outlet from a cylindrical element which is fastened coaxially in the burner body by an electrical insulator; this is located in the rear, cool part of the burner. An electrical clamp is connected to the cylindrical middle element, which, in connection with the feed regulating and control system, is led out of the outer part of the burner body through the insulation bushing.

Im Brenner, geht nach der 1. Variante, das im Brennerkörper koaxial befestigte zylindrische Element eine Brennstoffkammer, in die Brennstoffdüse mit einer zylindrischen Endung über. Die Länge der zylindrischen Düsenendung ist so gewählt, daß sich ihr Ende in der Brennerflamme befindet und die Ionisationselektrode bildet. Auf der Brennstoffdüse befindet sich der Gemischdrallkörper mit davor und dahinter radial angelegten Kanäle der Luftmündung. Auf dem inneren Umfang der Brennkammer in ihrem vorderen Teil befindet sich eine scharfe Kante, die gegenüber einer scharfen Kante am Umfang der Brennstoffdüse angeordnet wird und den Umfangselektrodenabstand bildet.In the burner, according to the first variant, the cylindrical element, which is coaxially fastened in the burner body, merges a fuel chamber into the fuel nozzle with a cylindrical end. The length of the cylindrical nozzle end is chosen so that its end is in the burner flame and forms the ionization electrode. The mixture swirl body is located on the fuel nozzle with the air outlet channels radially in front and behind it. On the inner periphery of the combustion chamber in its front part there is a sharp edge which is arranged opposite a sharp edge on the periphery of the fuel nozzle and which forms the peripheral electrode spacing.

Nach der 2. Variante, bildet der Raum in dem zylindrischen Element das koaxial im Zylinder mit dem größeren Durchmesser angeordnet ist eine Brennstoffkammer. Die sich kegelförmig verengende Brennstoffkammer und die sich kegelförmig verbreiternde Endung des Mittelelements bilden an der Mündung die Umfangselektrodendüse. Die Länge des Mittelelements ist so gewählt, daß sich sein Ende mit der ausgestalteten Endung in der Brennerflamme befindet. Ein Gemischdrallkörper befindet sich an der Innenwand der Luftkammer gegenüber radial angeordneten Brennstoffkanälen in der Brennstoffdüse.According to the second variant, the space in the cylindrical element which is arranged coaxially in the cylinder with the larger diameter forms a fuel chamber. The conically narrowing fuel chamber and the conically widening end of the middle element form the peripheral electrode nozzle at the mouth. The length of the central element is chosen so that its end with the designed end is in the burner flame. A mixture swirl body is located on the inner wall of the air chamber opposite to radially arranged fuel channels in the fuel nozzle.

Nach der 3. Variante verbindet sich die Luftkammer im Brenner mit der Luftrohrleitung, in dessen Inneren sich das koaxial angelegte zylindrische Element befindet, das die Gasleitung und gleichzeitig elektrische Leitung bildet.According to the third variant, the air chamber in the burner connects to the air pipe, inside which there is the coaxial cylindrical element that forms the gas line and at the same time the electrical line.

Das zylindrische Element stützt sich auf die Luftrohrleitung durch Isolatoren, am besten als keramische Walzen ausgebildet, die im Umfang radial oder axial angeordnet werden. Die Luftleitung endet mit einer kegelringförmigen Mischkammer, die an der Mündung mit der Brennkammer verbunden ist, in der sich die Mündung des zylindrischen Elements mit der Brennstoffdüse und einer Endung befindet.The cylindrical element is supported on the air pipe by insulators, best designed as ceramic rollers, which are arranged radially or axially in the circumference. The air line ends with a conical annular mixing chamber, which is connected at the mouth to the combustion chamber, in which the mouth of the cylindrical element with the fuel nozzle and an end is located.

Die Verbindung des isolierten Mittelelements mit einer Hochspeisungsspannung, einer Ionisationsspannung für die Flammendetektion und mit dem Steuerungssystem des Gas- und Brennluftzuflußes ermöglicht die automatische Zündung, Detektion und Flammenkontrole sowie die Kontrolle über Brennqualität des Brennstoffgemisches.The connection of the insulated middle element with a high supply voltage, an ionization voltage for flame detection and with the control system of the gas and combustion air inflow enables automatic ignition, detection and Flame control and control over the burning quality of the fuel mixture.

In Brennern mit großen Wärmeleistungen wird die richtige Brennstoffverteilung durch Verwendung einer Umfangsdüse wie beim Brenner nach der 2. Variante erreicht. Die Lösung (Variante 3) ermöglicht den Bau sehr langer Brenner, die in hoher Umgebungstemperatur arbeiten können, da sich der elektrische Anschluß der Zündung und der Kontrolle in sicherer Entfernung von der Wärmequelle befindet.In burners with high heat outputs, the correct fuel distribution is achieved by using a circumferential nozzle as in the burner according to the second variant. The solution (variant 3) enables the construction of very long burners that can work in high ambient temperatures, since the electrical connection of the ignition and the control is at a safe distance from the heat source.

Da die Mischung des von der Luft getrennten Gases am Ende der Brennkammer erfolgt, und die durchfließende Luft zusätzlich den Brennerkörper kühlt, wird es ermöglicht Brenner größerer Wärmeleistung zu bauen. Diese Brenner sind besonders fur die Zündung großer Gasüberschüsse in Gasfackeln nützlich.Since the gas separated from the air is mixed at the end of the combustion chamber and the air flowing through it also cools the burner body, it is possible to build burners with a higher heat output. These burners are particularly useful for igniting large excess gas in gas flares.

Der zusätzliche Vorteile des Brenners besteht in der Möglichkeit, das verlängerte Teil als Konstruktionsmodule zu bauen, sowie in der Einfachheit des Anbaus an industrielle Installationen. Die Brenner sind einfach im Bau und erfüllen Hauptfunktionen von Brennern für den automatischen Betrieb.The additional advantages of the burner are the possibility to build the extended part as construction modules, as well as the simplicity of the attachment to industrial installations. The burners are simple in construction and fulfill the main functions of burners for automatic operation.

Das zylindrische Element 6 stützt sich mit Isolatoren 23 an der Luftrohrleitung 21 ab. Die Isolatoren 23 in Form von Walzen können axial oder radial verteilt werden.The cylindrical element 6 is supported by insulators 23 on the air pipe 21. The insulators 23 in the form of rollers can be distributed axially or radially.

Die Luft wird durch den Luftzuflußkörper 2 in die Luftkammer 4 und der Brennstoff durch den Brennstoffzuflußdrallkörper 3 in die Brennstoffkammer 7 zugeliefert. Der Brennstoff, der sich mit der durch den Drallkörper verwirbelten Luft mischt, bildet das Brenngemisch. Die Zündung des Brennstoffgemisches wird durch die Hochspannungsführung aus dem Speisungssystem 13 durch die Isolationsdurchführungskerze 12 und die elektrische Klemme 11 an das Element 6 erreicht. Ein Funkenüberschlag zwischen den scharfen Kanten 18 und 19 bei der 1. und 3. Variante oder zwischen dem zylindrischen Element 6 und der Düsenendung bei der 2. Variante, verursacht die Entzündung des Brennstoffgemisches. Das brennende Brennstoffgemisch verursacht am Detektions- und Flammenkontrollumfang entsprechende elektrische Signale, die durch das Speisungs-, Regulierungs- und Steuerungssystem 13 für die automatische Regulierung der Verbrennungsqualität und die Brennerarbeit genutzt werden.The air is supplied through the air inflow body 2 into the air chamber 4 and the fuel through the fuel inflow swirl body 3 into the fuel chamber 7. The fuel that mixes with the air swirled through the swirl body forms the fuel mixture. The ignition of the fuel mixture is achieved by the high-voltage lead from the supply system 13 through the insulation feed-through plug 12 and the electrical terminal 11 to the element 6. A flashover between the sharp edges 18 and 19 in the 1st and 3rd variant or between the cylindrical element 6 and the nozzle end in the 2nd variant causes the fuel mixture to ignite. The burning fuel mixture causes corresponding electrical signals at the detection and flame control range, which are used by the feed, regulation and control system 13 for the automatic regulation of the combustion quality and the burner work.
