Aucli durch an sich bekannte iiauliche Maß- natl:nen, "sie -fas Abdecken Bier oberen Ofen- iittnun- und ..las Absaugen der A1igase durch geeignete Saugvorrichtungen, werden die schädlichen Bestandteile der Abgase nicht vollständig vnrlie-ende Erfindung hetritit nun ein erfahren, welches die vtir`aianntcn 1'liel- stäude in einfacher Weise i;eseitit und dabei noch den großen wirtschaft:ichen Vorteil zeitigt. #laß leben eitler Erecnstottersparnis teer Durchsatz an Riistgut erheblich gesteigert werden kann. Die Erfinrlun- bedient sich dabei eines an sich bekannten Mittels zur Verdichtung saurer Gase, nämlich fein zerstäubten Was- sers, wodurch eine niii-liclist innige Derüh- rung der Gase mit dein Wasser hervorgerufen werden soll. Derartige Einrichtungen dienen häufig zur Bekämpfung des Hüttenrauches. Dabei wird (las Wasser z«veckmä@iig in zum Basstrom entgegengesetzter Richttang einge- führt, während die Erfindun- dadurch, (Saß Gasstrom und Wasserstrahl in gleicher Rich- tung geführt werden, noch einen besonderen Vorteil erzielt, indem ein erheblicher Zug auf 3en Ofen ausgeübt wird. Auf der beiliegen- jen Zeichnung ist beispielsweise eine @'or- -iclittIng zur Durchführung ies @-e rfahrens :n iäl3 der Erfin(hin- Aar estellt. und zwar zeigt #-iie_@bbildung einen senkrechtenSchnitt durch einen Erzröstofen.

Diesem Trichter f ist in geeigneter Form, wie neispiels«-eise in Ahb. i dargestellt, ein Ka- in;nrohr vorgelagert, in welches durch eine der allgemein bekannten ltrahiciüsen li und unter Druck ein fein verteilter- Strahl einer trrlpfbaren Flüssigkeit oder auch eines Ge- inisches aus tropfbaren und gasförmigen Flüs- .ig-keiten ein-espritzt wird.
