Patentiert im Deutschen Reiche vom 4. Oktober 1910 ab.Patented in the German Empire on October 4, 1910.
Den Gegenstand der vorliegenden Erfindung bildet ein Verfahren und eine Vorrichtung, um die Sublimation des Schwefels in Schwefelöfen, Kiesöfen u. dgl. entweder zu vermeiden bzw. etwa sublimierten oder sublimierenden Schwefel derart zu verbrennen, daß dabei möglichst niedere Temperaturen angewandt und die Bildung von S O3 vermieden wird. Es ist bereits vorgeschlagen worden,The subject of the present invention is a method and a device to either avoid the sublimation of sulfur in sulfur furnaces, gravel furnaces and the like or to burn sublimed or sublimated sulfur in such a way that the lowest possible temperatures are used and the formation of S. O 3 is avoided. It has already been suggested
ίο zwecks Verhinderung einer unvollständigen Verbrennung des Schwefels in solchen öfen, sowie zur Verbrennung von Schwefeldämpfen hocherhitzte Luft in die Verbrennungskammer selbst einzuführen, welche bei der hierbei in der Verbrennungskammer erzielten, sehr hohen Temperatur sich unmittelbar mit den Dämpfen zu Schwefelsäureanhydrid vereinigte, welches alsdann durch weitere Temperaturerhöhung, beispielsweise bis auf etwa 12000C, wieder in seine Komponenten, das heißt in schweflige Säure und Sauerstoff, zerlegt wurde. Hierbei war nicht allein eine sehr hohe, großen Brennstoffaufwand erfordernde und das Material der öfen und Röhren sehr stark beanspruchende und schädigende Temperatur notwendig, sondern es bedurfte noch eines zusätzlichen Brennstoffaufwandes, um Ofen, Züge und Röhren zunächst überhaupt vorzuerhitzen, und durch die Einführung der Luft direkt in die Verbrennungsöfen ergab sich falscher Zug und Ausrauchen der öfen und demgemäß auch außerordentliche Schwierigkeiten in der Regelung des Ofenganges. Im Gegensatz dazu wird nun bei der vorliegenden Erfindung derart verfahren, daß man eine derartige hohe Erhitzung überhaupt vermeidet und die Bildung von Schwefelsäureanhydrid möglichst ausschließt, was im wesentlichen dadurch geschieht, daß man die zum Verbrennen des unöxydierten Schwefels nötige Luft gar nicht in den Ofenraum selbst oder in die Züge einführt, sondern die Luft erst nachdem die anfängliche Oxydation beendet ist, also außerhalb des Ofens oder des Verbrennungsraums den aus diesem austretenden Gasen zuführt, in welchen der übersublimierende Schwefel enthalten ist. Dadurch vermeidet man überhaupt die Notwendigkeit einer so hohen Temperatur im Verbrennungsraum, daß Schwefelsäureanhydrid und Verdampfung des Schwefels entsteht, und kann den Ofengang leicht regeln und Ausrauchen verhüten. Gleichzeitig werden aber dadurch die übergerissenen festen Schwefelteilchen sowie sich etwa an den Röhren ansetzender Schwefel verbrannt, und auch in den die abgehenden Gase bzw. deren Mischung mit Luft aufnehmenden Kanälen und Röhren kann die Reaktion leicht derart geleitet werden, daß auch hier Anhydridbildung vermieden wird. Die abgehenden Gase bzw. deren Gemisch mit Luft leitet man durch gut leitende metallische, beispielsweise gußeiserne Röhren und verfährt dabei derart, daß man die Gase bzw. deren Gemisch mit Luft gleichzeitig dazu verwendet, um in der üblichen Weise durch Wärmeaustausch mit dem verbrennenden Material dessen zu hohe Erhitzung und die Entstehung einer zu hohen, zur BiI-ίο to prevent incomplete combustion of the sulfur in such furnaces, as well as for the combustion of sulfur vapors, to introduce highly heated air into the combustion chamber itself, which at the very high temperature achieved in this way in the combustion chamber combined directly with the vapors to form sulfuric anhydride, which then through further Temperature increase, for example up to about 1200 0 C, was broken down again into its components, that is, into sulfurous acid and oxygen. This not only required a very high, high fuel consumption and the material of the furnaces and tubes very stressful and damaging temperature, but it also required an additional fuel expenditure in order to preheat the furnace, trains and tubes at all, and through the introduction of air Directly in the incineration furnace there was a wrong draft and smoking of the furnace and accordingly also extraordinary difficulties in the regulation of the furnace passage. In contrast, the present invention proceeds in such a way that such a high level of heating is avoided at all and the formation of sulfuric anhydride is excluded as far as possible, which essentially happens because the air necessary for burning the unoxidized sulfur is not even entered into the furnace space itself or introduces it into the flues, but only after the initial oxidation has ended, i.e. outside the furnace or the combustion chamber, supplies the gases exiting from this, in which the oversublimating sulfur is contained. This avoids the need for such a high temperature in the combustion chamber that sulfuric anhydride and evaporation of the sulfur are produced, and the furnace can be easily regulated and smoking prevented. At the same time, however, the solid sulfur particles that have been torn over and any sulfur that has accumulated on the pipes are burned, and the reaction can also be easily conducted in the ducts and pipes that take up the outgoing gases or their mixture with air in such a way that anhydride formation is avoided here too. The outgoing gases or their mixture with air are passed through highly conductive metallic, for example cast iron pipes and the procedure is such that the gases or their mixture with air are used at the same time to in the usual way by heat exchange with the burning material too high heating and the creation of too high a
