 geringe Druck hat natürlich auch   für das Dichthalten   aller Dichtungen seine Vorteile. Der geringe Überdruck in der Windzuleitung lässt sich auch erreichen, durch Anordnung eines saugend wirkenden Gebläses, das sich   z. B. empfiehlt, wenn   man die beim Eintritt der Gase in das Zugrohr bzw. bei der in das letztere eingesetzten Drosselklappe noch vorhandene Wärme weiter ausnutzen oder die in den Verbrennungs- oder Abgasen vorhandene Kohlensäure verwerten will.

   Die Luft wurde dann an der genannten Drosselklappe eintreten, ohne dass an der   Anlage   selbst irgend welche Änderung vorgenommen zu werden braucht.

 einander   gegenüberliegende Düsen c,   die durch rohrartige Luftkanäle d mit zwei zu beiden Seiten des Schachtes b aufgestellten Lufterhitzungsapparaten e in Verbindung stehen. Beide genannte Apparate   8   stehen an ihren Decken durch eine Rohrleitung untereinander in Verbindung, können aber jeweilig voneinander durch eine Klappe f getrennt werden. die in 
 EMI2.3 
 sich in demselben und gelangt durch den rechtsseitigen Kanal d nach der rechtsseitigen Dase   r,   aus der die erhitzte Luft aus-und in die untere Schmelzzone   a des Ofenerhachtes   übertritt.

   Nach dem Durchströmen der   Heissluft   durch die Schmelzzone in horizontaler oder nahezu horizontaler Richtung tritt die Luft als Abgas in die linksseitige Düse c über, durchstreicht den hier gelegenen Kanal   d   und gibt ihre in der Schmelzzone a aufgenommene Hitze an den linksseitigen   Lufterhitzungsapparat   e ab, der dann für die Aufnahme von 
 EMI2.4 
 steht. Nach dem Austritt der mehr oder weniger heissen Abgase oben aus dem linksseitigen Apparat e werden dieselben in der strichpunktiert angegebenen Richtung an der Klappe j vorbei nach dem Abzugsrohr t weitergeleitet. 



   Wird nach bestimmter Zeit die Klappe f in bekannter Weise umgestellt, so strömt dann die vom Gebläse h eingesaugte Luft in   entgegengesetzt-er Richtung durch   den links- 
 EMI2.5 
 rechte Lage umgestellt wird. Sinkt nämlich die Schmelzfläche im Ofen, so geht naturgemäss der Gebläsewind auf dem kürzesten Wege. d. b. durch den Schmelzofen selbst nach oben und die Luft durchstreicht den Ofenschacht. Bei geschlossener (wagerechter) Stellung der Drosselklappe k sowie bei offener (ebenfalls wagerechter) Stellung der Klappe   f   kann die Luft gleichzeitig von beiden Seiten in den Ofen treten und der Schmelzvorgang   kann8 In   Ende geführt werden..

 EMI2.1
 Of course, low pressure also has its advantages for keeping all seals tight. The low overpressure in the wind supply line can also be achieved by arranging a suction fan, which z. B. recommends, if you want to use the heat still present when the gases enter the draft tube or the throttle valve inserted in the latter, or if you want to utilize the carbonic acid present in the combustion gases or exhaust gases.

   The air would then enter the throttle valve mentioned without any changes having to be made to the system itself.
 EMI2.2
 Opposite nozzles c, which are connected through tube-like air ducts d with two air heating devices e set up on both sides of the shaft b. Both of these apparatuses 8 are connected to one another at their ceilings by a pipeline, but can be separated from one another by a flap f. in the

 is in the same and passes through the right-hand channel d to the right-hand Dase r, from which the heated air passes out and into the lower melting zone a of the furnace roof.

   After the hot air has flown through the melting zone in a horizontal or almost horizontal direction, the air passes as exhaust gas into the left-hand nozzle c, passes through the channel d located here and gives off the heat it has absorbed in the melting zone a to the left-hand air heating apparatus e, which then for the inclusion of
 EMI2.4
 stands. After the more or less hot exhaust gases emerge from the left-hand apparatus e at the top, they are passed on in the direction indicated by dash-dotted lines past the flap j to the exhaust pipe t.



   If, after a certain time, the flap f is adjusted in a known manner, the air sucked in by the fan h then flows in the opposite direction through the left-
 EMI2.5
 right position is changed. If the melting surface in the furnace sinks, the fan wind naturally takes the shortest route. d. b. up through the furnace itself and the air passes through the furnace shaft. When the throttle valve k is closed (horizontal) and when the valve f is open (also horizontal), the air can enter the furnace from both sides at the same time and the melting process can be carried out.
