Description

Die Wandungen von Gasgeneratoren oder anderen durch Hitzeeinwirkung hoch beanspruchten Einrichtungen sind vielfach diesen Beanspruchungen nicht gewachsen, so daß mit der Zeit ein Durchbrennen oder eine sonstige Zerstörung der Wandungen bzw. Wandungsoberflächen eintritt.The walls of gas generators or others due to the effects of heat highly stressed facilities are often not able to cope with these demands, so that over time a burning through or other destruction of the walls or wall surfaces occurs.

Die Erfindung besteht demgegenüber darin, daß die Wandungen, insbesondere an den durch die `Wärmeeinwirkung besonders hoch beanspruchten Stellen, durch eine in Auftragsschweißung hergestellte Schicht, z. B. aus einer hochhitzebeständigen Stahllegierung, geschützt bzw. widerstandsfähig gemacht werden. Bei Gasgeneratoren sind dieses insbesondere die die Luftdüse umgebenden Wandungsteile sowie die der Feuerzone des Generators am stärksten ausgesetzten Stellen, z.B. (vor allem bei schräg nach abwärts gerichteter Luftdüse) der Boden oder die der Luftdüse gegenüberliegende Wandung des Generators. Außer den Wandungen des Generators selbst kann ferner insbesondere das Düsenmundstück der Luftdüse mit einer durch Auftragsschweißung hergestellten Schutzschicht versehen werden.The invention consists in that the walls, in particular in the areas that are particularly heavily stressed by the heat, by a layer produced in build-up welding, e.g. B. from a highly heat-resistant Steel alloy, protected or made resistant. With gas generators these are in particular the wall parts surrounding the air nozzle as well as those of the Fire zone of the generator at the most exposed places, e.g. (especially at downward sloping air nozzle) the floor or the one opposite the air nozzle Wall of the generator. In addition to the walls of the generator itself, in particular the nozzle mouthpiece of the air nozzle with one produced by build-up welding Protective layer are provided.

Durch die Erfindung kann der Abbrand an den Wandungen, an der Düse oder an sonstigen den Ilitzeeinwirkungen ausgesetzten Wandungsteilen, welcher bisher Ursache einer verhältnismäßig begrenzten Lebensdauer des Generators war bzw. ein häufiges Auswechseln der Luftdüse erforderlich machte, praktisch vollständig unterbunden werden.The invention can reduce the burn-off on the walls, on the nozzle or on other wall parts exposed to the effects of the Ilitze, which previously The cause of a relatively limited service life of the generator was or was a frequent replacement of the air nozzle made necessary, practically completely prevented will.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung in einem Schnitt durch die Luftdüse senkrecht zur Generatorachse dargestellt, und zwar zeigt die Abbildung eine z. B. aus Stahl gefertigte Luftdüse a eines Gasgenerators, dessen Herdmantelwandungen b, in welche ein Flansch c zum Befestigen der Luftdüse eingeschweißt ist, in der Umgebung der Düse durch eine hochhitzebeständige Auftragsschweißung d gegen die Hitzeeinwirkungen infolge Strahlung oder Wärmeleitung aus der vor der Luftdüse sich befindenden heißesten Stelle der Feuerzone geschützt sind, desgleichen das Mundstück der Luftdüse a durch eine Auftragsschwei-Bung e. Das Aufschweißen erfolgt insbesondere durch Verwendung von Spezialelektroden aus einer hochhitzebeständigen Stahllegierung.In the drawing, an embodiment of the invention is in one Section through the air nozzle shown perpendicular to the generator axis, namely shows the figure a z. B. made of steel air nozzle a of a gas generator whose Hearth jacket walls b, into which a flange c is welded to attach the air nozzle is, in the vicinity of the nozzle by a highly heat-resistant build-up weld d against the effects of heat as a result of radiation or heat conduction from the before Air nozzle located in the hottest part of the fire zone are protected, as well the mouthpiece of the air nozzle a through an overlay weld e. The welding takes place in particular through the use of special electrodes made of a highly heat-resistant Steel alloy.

Gegebenenfalls können auch die Wandungen an einzelnen Stellen durch das Schweißmaterial selbst gebildet werden.If necessary, the walls can also pass through at individual points the welding material itself can be formed.
