  Der technische Fortschritt, welcher durch dieses Verfahren, verglichen mit der bisherigen   
 EMI2.1 
 lichen Erzeugung von schwefeliger Säure benutzen kann, indem man die einen Luftüberschuss enthaltenden Röstgase der Muffelöfen zur Röstung der Erze in die Schachtöfen leitet, wobei diesen durch die   Heizkanäle.     f   Wärme zugeführt werden kann, was insbesondere für schwefelarme oder hei hoher Temperatur röstende Stoffe in Betracht kommt. Bei Verwendung der so erhaltenen schwefeligen Säure für die Erzeugung von Schwefelsäure hat man darauf zu achten, dass keine Mischung der Heiz- und Röstgase stattfindet. 



    PATENT-ANSPR ÜCHE :  
1. Verfahren zur   Verhüttung von   Schwefel enthaltenden Stoffen durch Destillation im   Oft'n,   dadurch gekennzeichnet, dass die in einem ein-oder mehrteiligen Schachtofen gefüllte pulver- oder stückförmige Beschickung durch sauerstoffreie (verbrannte) Generatorgase, die durch in der Beschickung frei gehaltene Kanäle   eingeführt   werden, unmittelbar beheizt wird, wobei die Generatorgase die entwickelten Schwefeldämpfe aus dem Ofen zur weiteren Verarbeitung   abfiihren, ohne mit   metallischen Bestandteilen des Ofens in Berührung zu kommen.

   lying plates in the muffle furnace. You can also use the shaft furnace directly with an automatic furnace, for. B. von Heereshoff, unite.



  The technical progress achieved by this process compared to the previous one
 EMI2.1
 Union production of sulphurous acid can be used by passing the roasting gases of the muffle furnaces containing an excess of air for roasting the ores into the shaft furnaces, this through the heating ducts. f heat can be supplied, which is particularly suitable for low-sulfur substances or substances that roast at high temperatures When using the sulphurous acid obtained in this way for the production of sulfuric acid, care must be taken that the heating and roasting gases are not mixed.



    PATENT CLAIMS:
1. A method for smelting sulfur-containing substances by distillation in Oft'n, characterized in that the powder or lumpy charge filled in a one-part or multi-part shaft furnace is introduced by oxygen-free (burned) generator gases through channels kept free in the charge are heated directly, with the generator gases removing the evolved sulfur vapors from the furnace for further processing without coming into contact with metallic components of the furnace.

2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass die bei dem Verfahren gemäss Anspruch l zurückbleibenden noch heissen Massen durch Rösten mit Luft in an sich bekannter Weise auf schwefelige Säure verarbeitet werden, um eine vollständige Schwefel- aupheute zu erreichen. 2. The method according to claim 1, characterized in that the still hot masses remaining in the method according to claim 1 are processed into sulphurous acid by roasting with air in a manner known per se in order to achieve complete sulphurous acidity. 3. Vorrichtung zur Ausführung des Verfahrens nach Anspruch 1, gekennzeichnet durch einen Schaclstofen (a), der von unten offenen Querrohren (b) durchzogen ist, welche EMI2.2 3. Apparatus for carrying out the method according to claim 1, characterized by a Schaclstofen (a), which is traversed from below open cross tubes (b), which EMI2.2
