Description
<Desc/Clms Page number 1>
Verfahren zur Verhinderung der Staubverschwelung sowie zur Erhöhung der Heizfläehcnwirkung, insbesondere bei Luftwärmeöfen.
Durch das den Erfindungsgegenstand bildende Verfahren wird die sengende Wirkung von Luftheizflächen, die eine Verschwelung des organischen Staubes bewirkt, aufgehoben und ausserdem die Heizflächenwirkung bedeutend erhöht.
Dieser Erfolg wird dadurch hervorgebracht, dass die zur Befeuchtung der Luft notwendige Wassermenge in Form von zerstäubtem Wasser oder Wasserdampf längs den Heizflächen ge- leitet wird.
Dadurch wird der den Heizflächen zunächst streichende Luftstrom mit Wasserdampf übersättigt, die Staubteilchen werden Tropfen- oder Dampfbläschenträger und werden. nach dem Leidenfrostschen Phänomen, unter heftiger Dampfzerstäubung von den Heizflächen abgeschleudert.
Ausserdem aber werden durch die Wasser-oder Dampfzerstäubung Luftwirbel erzeugt, welche eine heftige Luftmischung an den Heizflächen hervorrufen. Diese Luftwirbelung erschwert einerseits die Staubverschwelung dadurch, dass sie dem Staub die zur Verschwelung notwendige Zeit und Trägheit nimmt und durch die starke Luftmischung, die für eine rasche Zersetzung des Staubes notwendige Temperatur nicht aufkommen lässt.
Andererseits wird die Heizflächenwirkung durch die Luftwirbelung fast auf das Doppelte erhöht, wie Rietschel und andere Forscher festgestellt haben.

Process to prevent the carbonization of dust and to increase the heating surface effect, in particular in the case of air heating ovens.
The method forming the subject of the invention eliminates the searing effect of air heating surfaces, which causes the organic dust to smolder, and also significantly increases the heating surface effect.
This success is brought about by the fact that the amount of water required to humidify the air is conducted in the form of atomized water or water vapor along the heating surfaces.
As a result, the air stream that initially brushes the heating surfaces is oversaturated with water vapor, and the dust particles become carriers of drops or vapor bubbles. according to the Leidenfrost phenomenon, thrown from the heating surfaces with violent steam atomization.
In addition, however, the water or steam atomization generates air eddies, which cause a violent air mixture on the heating surfaces. On the one hand, this air turbulence makes the dust smoldering more difficult because it takes the time and inertia away from the dust for smoldering and because of the strong air mixture, which prevents the temperature necessary for rapid decomposition of the dust.
On the other hand, the heating surface effect is almost doubled by the air turbulence, as Rietschel and other researchers have established.
** WARNING ** End of DESC field may overlap beginning of CLMS **.
