 des   Luft-Wasscrdumpfgemiselles,   welches durch die Leitungen G, H von oben zugeleitet wird, indem   dasselbe gezwungen wird, unter der Prcllplatte   hindurch nach der anderen Abteilung des Topfes zu strömen. 



   Geschmolzenes Blei wird durch den Heber J in geeigneten Zwischenräumen eingeführt, wogegen das Bleioxyd durch den Kanal   K   nach den   Absetzkammern   entweicht. Der untere Teil des Kessels wird durch eine Feuerung üblicher Konstruktion erhitzt und der ganze Kessel mit Mauerwerk oder sonstigem, die Wärme schlecht leitendem Material umgeben, um die Hitze innerhalb-des Kessels vollständig zusammenzuhalten. 



   Der Vorgang bei der Bleioxydation innerhalb dieses Kessels ist der in dem Stammpatent angegebene. Eine bestimmte, nicht sehr grosse Charge geschmolzenes Blei wird durch den Heber J in den Topf A eingeführt, nachdem vorher das Rührwerk D in eine sehr schnelle Umdrehung versetzt worden ist.   Die Höbe   der Charge wird so eingerichtet, dass das Rührwerk gerade vom Blei bedeckt wird, wogegen die   Prellplatt   sich um wenige Zentimeter über dem Niveau des Bleis befindet, so dass also zwischen dem unteren Rande der   Prellplatte und dem   Niveau des   geschmolzenen Hieis noch   ein enger Spalt zum Durchtritt des zur Oxydation dienenden LuftWasserdampfgemisches bleibt.

   Das Luft-Wasserdampfgemisch wird (auf die geeignete Temperatur erhitzt) in grossem Oberschuss in den Kessel eingeblasen und durch die darin vorherrschende   Wurme findet eine rasche Oxydation   des metallischen Bleis statt. Sollte sich trotzdem etwas metallisches Blei der Oxydation entziehen, so hat dasselbe in dem hohen Oxydationstopfc, in

 EMI2.1
 of the air-water vapor mixture, which is fed in through the lines G, H from above, by forcing it to flow under the baffle plate to the other compartment of the pot.



   Molten lead is introduced through the lifter J in suitable interstices, while the lead oxide escapes through the channel K to the settling chambers. The lower part of the boiler is heated by a furnace of the usual construction and the entire boiler is surrounded by masonry or other material that does not conduct heat well in order to keep the heat completely together within the boiler.



   The process of lead oxidation within this boiler is the one specified in the parent patent. A certain, not very large batch of molten lead is introduced into the pot A through the lifter J after the agitator D has been set in a very fast rotation. The height of the charge is set up so that the agitator is just covered by the lead, whereas the baffle plate is a few centimeters above the level of the lead, so that there is still a narrow gap between the lower edge of the baffle plate and the level of the melted ice remains for the passage of the air-water vapor mixture used for oxidation.

   The air-steam mixture (heated to the appropriate temperature) is blown into the boiler in large excess and the worms that predominate in it cause rapid oxidation of the metallic lead. Should some metallic lead nevertheless escape oxidation, it has it in the high oxidation pot

 subject to oxidizing treatment.
