Abstract

The overheating prevention equipment for oil, gas fired afterburner burners is for units with a vertical hinge (3) on one side of the furnace wall opening and a retractable locking pin (2) on the other. the equipment comprises two conventional double-acting hydraulic or pneumatic jacks. One of these is arranged to operate the locking pin. The other (6) is connected horizontally to the furnace front and burner so that it can rotate through 90 deg. from its firing position. Electromagnetic valves in the lines to the jacks are so connected that if power fails the burner is rotated to the non-firing position. Power restoration reverses the process.

Description

Vorrichtun zur Vermeidung von Überhitzlangsschäden für Brenner an Nachverbrennungsanlagen Gegenstand der Erfindung ist eine Schutzvorrichtung für Öl-und Gasbrenner an Nachverbrennungsanlagen dadurch gekennzeichnet, daß zwecks Vermeidung von über iene sschäden durch wärmestan und Wärmestrahlung diese bei Stromausfall mittels an sich @ckennter Pneumatik- @ . hydraulikay@@nder an der Brennkammeröffnung der Nachverbrennungsanlage gesenken wird.Device for avoiding long-term overheating damage to burners Afterburning systems The invention relates to a protective device for Oil and gas burners on post-combustion systems, characterized in that for the purpose Avoidance of excessive damage from heat build-up and thermal radiation in the event of a power failure by means of @ckennter pneumatics @. hydraulikay @@ nder at the combustion chamber opening the afterburning plant is lowered.

Es ist eine derartige Vorrichtung bekannt, die bei Stromausfall ein mit ebeständ es Schlid in der Brennkammeröffnung vor den Brenner schliebt und so @lt überhitzungsschäden an Brenner vermieden werden. It is known such a device that in the event of a power failure with ebeständ it closes in the combustion chamber opening in front of the burner and so on @lt overheating damage to the burner can be avoided.

Nachteilig bei dieser Anordnung ist, daß der nachträgliche Einbau äußerst kompliziert ist. Weiterhin ist von Nachteil, daß der Aufwand bei der Neuerstellung einer Nachverbrennungsanlage mit dieser Vorrichtung sehr hoch ist. In beiden Fällen muß das hitzebenständige Schild in der Brennkammeröffnung so angeordnet sein, daß die Luftführung des Brenners nicht negativ beeinflußt wird. Die Lebensdauer des Schildes ist wegen der starken Hitzeeinwirkungs begrenzt.The disadvantage of this arrangement is that the subsequent installation is extremely complicated. Another disadvantage is that the effort involved in creating a new one an afterburning system with this device is very high. In both cases the heat shield must be arranged in the combustion chamber opening in such a way that the air flow of the burner is not adversely affected. The lifetime of the The shield is limited because of the strong heat exposure.

Aufgabe der Erfindung ist es, diese Nachteile zu beseitigen. Die Lösung der Aufgabe besteht darin, daß an sich bekannte Luft- oder Hydraulikzylinder an dem Brenner so angeordnet sind, um ihn bei Stromausfall aus der gefährdeten bis zu 800° C heißen Zone auszuschwenken.The object of the invention is to eliminate these disadvantages. The solution the task is that known air or hydraulic cylinders to the burner are arranged to take it off the endangered up in the event of a power failure Swing out to a hot zone of 800 ° C.

In vorteilhafter Weise kann diese Vorrichtung, die im wesentlichen nur aus zwei Zylindern und zwei elektrischen Schaltgliedern besteht, auch nachträglich von außen sichtbar mit geringem Aufwand montiert werden. Somit werden in keiner Weise die Brennereigenschaften, insbesondere die Luftführung, nachteilig beeinflußt.Advantageously, this device, which essentially only consists of two cylinders and two electrical switching elements, even afterwards visible from the outside with little effort. Thus, in none Way, the burner properties, especially the air flow, adversely affected.

Die Zeichnung gibt ein Ausführungsbeispiel der Erfindung wieder. Sie zeigt in schematischer Darstellung einen Brenner in ausgeschwenkter Stellung 90° zur Brennraumachse.The drawing shows an embodiment of the invention. she shows a schematic representation of a burner in the swiveled out position 90 ° to the axis of the combustion chamber.

Der Brenner (1) ist mit zwei Scharnieren (2) und (3) an der Stirnplatte der Brennkammer (4) verstiftet. Der Stift des Scharniers (2) wird vo der Kolbenstange des Riegelzylinders (5) ersetzt, der an der Stirnplatte (4) fluchtend über dem Scharnier (2) befestigt ist. Der Schwenkzylinder (6) ist an der Stirnplatte (4) und am Brenner (1) befestigt. Die zylinder (5) und (ob) sind an Preßluft oder ein I-tydraulikargregas angeschlossen. Fällt der Betriebsstrom der Nachverbrennungsanlage aus, wird ein Magnetventil geöffnet, wodurch der Riegelzylinder (5) und der Schwenkzylinder (6) ausgefahren werden. Der Brenner (1) schwenkt aus.The burner (1) has two hinges (2) and (3) on the front plate pinned to the combustion chamber (4). The hinge pin (2) is attached to the piston rod of the locking cylinder (5) replaced, the one on the front plate (4) in alignment over the hinge (2) is attached. The swivel cylinder (6) is on the face plate (4) and on the burner (1) attached. The cylinders (5) and (ob) are on compressed air or an I-tydraulikargregas connected. If the operating current of the afterburning plant fails, a Solenoid valve opened, whereby the locking cylinder (5) and the swivel cylinder (6) be extended. The burner (1) swings out.

Nach Einschalten des Betriebsstroms funktioniert das Einschwenken des Brenners in umgekehrter Reihenfolge.Swinging in works after the operating current is switched on the burner in reverse order.
