Description

Verfahren nebst. Glühgefäß zum Blankglühen: Beim Glühen in Glühgefäßen ist es bekannt, die in denselben enthaltene Luft durch Einbringen von brennbaren Stoffen, wie Kohle, Papier, Gas, in Kohlensäure überzuführen und dadurch unschädlich zu machen. Die Erfindung hat den Zweck, das Füllen der zu erhitzenden Glühkessel, Rohre oder Muffeln mit Gas zum Blankglühen gefahrlos zu gestalten. Zu diesem Ende wird nach der Erfindung das in den Glühkessel eingeführte Gas entzündet, hierauf die Zündöffnung im Glühkessel geschlossen. Das Gas verbrennt dann im Glühkessel mit der darin enthaltenen Luft; die Verbrennungsgase verdrängen die Luft und strömen durch ein anderes kleines Gasrohr am Kessel ab. Durch entsprechende Wände kann leicht dafür gesorgt werden, daß ein Gasumlauf im Kessel stattfindet und die Verbrennung der Luft eine vollständige wird.Procedure plus. Annealing vessel for bright annealing: When annealing in annealing vessels it is known that the air contained in the same by introducing combustible To convert substances such as coal, paper, gas into carbonic acid and thus harmless close. The invention has the purpose of filling the annealing boiler to be heated, To design pipes or muffles safely with gas for bright annealing. To this end according to the invention, the gas introduced into the annealing vessel is ignited, then the ignition opening in the glow boiler is closed. The gas then burns in the annealing boiler with the air it contains; the combustion gases displace the air and flow through another small gas pipe on the boiler. Appropriate walls can easily it must be ensured that a gas circulation takes place in the boiler and the combustion the air becomes a complete.

In der Zeichnung stellt a den Glühkessel, b das Zündloch dar, d ist das Gaseinführungsrohr, e die den Umlauf bewirkende Wand, f das Gasabführungsrohr. Sobald die Gasflamme nicht mehr genügende Luft im Kessel findet, erlischt sie von selbst; es strömt dann reines Gas in den Glühkessel und verdrängt die Verbrennungsgase..In the drawing, a represents the incandescent boiler, b the ignition hole, d the gas inlet pipe, e the wall causing the circulation, f the gas discharge pipe. As soon as the gas flame can no longer find enough air in the boiler, it goes out by itself; pure gas then flows into the annealing boiler and displaces the combustion gases.

Nach diesem Verfahren i'st die Entstehung eines explosiblen Gemisches ausgeschlossen. Sobald das am Rohr f ausströmende Gas brennbar ist, ist der Kessel mit Gas gefüllt.According to this process, an explosive mixture is formed locked out. As soon as the gas flowing out of the pipe f is flammable, the boiler is filled with gas.

In.-gleicher Weise kann nach dem Erkalten das im Kessel befindliche Gas unschädlich gemacht werden. Man schließt den Gashahn g, öffnet Lufthahn h und entzündet7_durch_EZündloch b das Gas.In the same way, the in the boiler can after cooling Gas can be rendered harmless. You close the gas cock g, open the air cock h and ignites7_by_EZündloch b the gas.

Nach Schließen des Zündloches erfolgt umgekehrt Verbrennung der eingeführten Luft in Gas.After the ignition hole has been closed, the introduced ones are reversed Air in gas.
