Description
Brennofen mit mittelbarer Beheizung. Brennöfen mit mittelbarer Beheizung, bei denen die Luft sich in Hohlräumen erhitzt, in ihnen nach,der Ofendecke aufsteigt, durch das Gut nach unten fällt, um durch: untere Öffnungen wieder in die Hohlräume zu gelangen, sind an sich bekannt. Ferner sind auch solche Ofen bekannt, bei denen einzelne voneinander getrennte Heizkörper die Ofenluft erhitzen.Kiln with indirect heating. Kilns with indirect heating, in which the air heats up in cavities, in them after the furnace roof rises, through the good falls down to through: lower openings back into the cavities to get are known per se. Such furnace are also known in which individual separate radiators heat the oven air.
Alle diese bekannten Anordnungen haben indessen den Nachteil, daß eine ungleichmäßige Erwärmung der Muffel eintritt, was durch ungleichmäßige Luftbewegung bedingt ist. Außerdem konnte bei diesen Anordnungen die Beheizung in den verschiedenen Teilen des Ofens ,nicht geregelt werden.All these known arrangements, however, have the disadvantage that uneven heating of the muffle occurs, which is caused by uneven air movement is conditional. In addition, the heating in the various Parts of the furnace, not regulated.
Die nachstehend beschriebene neue Anordnung vermeidet diese Nachteile dadurch vollkommen, daß eine Anzahl der von Heizgasen durchströmten Verbrennungskammern mit Zwischenräumen .so in das Innere des Brennofens eingebaut sind, daß sie im Verein mit den die Verbrennungskammern verbindenden neuartigen Zwischenwänden eine nach dem Brennraum ebene Wand bilden, hinter der Luftumlaufkanäle enstehen, die einen sehr gleichmäßigen Luftumlauf hervorrufen.The new arrangement described below avoids these disadvantages completely in that a number of the combustion chambers flowed through by heating gases with gaps. so built into the interior of the kiln that they are in association with the novel partition walls connecting the combustion chambers one after Form a flat wall behind the combustion chamber, behind which air circulation ducts are created cause very even air circulation.
Ein weiterer Vorteil ist dadurch erreicht, daß die Verbrennüngskammern einzeln regelbar beheizt werden können, wodurch im Innern des Ofens verschieden stark beheizte Zonen erzeugt werden können. Dies ist bei bestimmten Prozessen und; Ofenarten erforderlich und steigert die Wirtschaftlichkeit gegenüber den bisher .bekannten Ofenarten ganz bedeutend. Nach dem Verlassen der Heizkörper können die noch heißen Ofengase auch noch durch die hohle Wand des Ofens geleitet werden, -wodurch eine weitere Steigerung der Wärmeabgabe eintritt. Der Gang der Feuergase kann dabei ein beliebiger sein.Another advantage is achieved in that the combustion chambers can be heated individually, which means that the inside of the furnace is different strongly heated zones can be generated. This is with certain processes and; Oven types required and increases the economic efficiency compared to the previous ones . Known types of ovens are very important. After leaving the radiator, the furnace gases that are still hot are passed through the hollow wall of the furnace, -through which a further increase in heat output occurs. The course of the fire gases can thereby be any.
In Abb. 2 ist die Anordnung im Grundriß, in Abb. 3 im Längsschnitt und' in Abb. i im Querschnitt durch. die Verbrennungskammern gezeichnet, während Abb. 4 einen Querschnitt durch die Luftumlaufkanäle darstellt. a stellt den Ofenraum vor, in dem in der Nähe der Wand die- feuerleitenden Hohlkörper b angeordnet sind. Diese Hohlkörper sind miteinander durch unten und oben offene Ziv ischenwände c verbunden, wodurch zwischen b, c und der Wand d Luftumlaufkanäle e entstehen. Durch diese Kanäle läuft die Ofenluft in der in Abb.4 dargestellten Weise um.In Fig. 2 the arrangement is in plan, in Fig. 3 in longitudinal section and 'in Fig. i in cross section through. the combustion chambers drawn while Fig. 4 shows a cross section through the air circulation channels. a represents the furnace space before, in which the fire-conducting hollow bodies b are arranged in the vicinity of the wall. These hollow bodies are connected to one another by ziv ischen walls open at the bottom and top c connected, whereby between b, c and the wall d air circulation channels e arise. By The furnace air circulates through these channels in the manner shown in Fig.4.
