Description

Verfahren zum Kalzinieren im lKuffelofen. Beim Kalzinieren feuchter Substanzen in ununterbrochen arbeitenden Muffelöfen mit unmittelbarer oder mittelbarer Beheizung, bei denen die Führung des zu kalzinierenden Gutes im Gegenstrom zur Beheizung nicht möglich ist, tritt der Übelstand auf, daß das feuchte Material zu größeren Stücken. zusammenbackt, die beim Verlassen des Kalzinierofens einen nicht genügend kalzinierten Kern aufweisen.Method for calcining in a cuffle furnace. Moist when calcining Substances in continuously operating muffle furnaces with direct or indirect Heating in which the material to be calcined is guided in countercurrent to the heating is not possible, the inconvenience occurs that the moist material becomes larger Pieces. cakes that are not enough when you leave the calcining furnace have calcined core.

Um diesem Übelstande zu begegnen, werden bisher die zu kalzinierenden Materialien in einem besonderen Apparat einer entsprechenden Vortröcknung unterworfen.In order to counteract this inconvenience, the to be calcined so far The materials are subjected to appropriate pre-drying in a special apparatus.

Durch vorliegende Erfindung werden die angeführten Übelstände beseitigt. Führt man nämlich das zu kalzinierende Gut durch das Gas- bzw. Dampfabzugsrohr dem Kalzinierapparat zu, so wird auf dem Zuführungswege das eingeführte Material unmittelbar durch den aus dem Kalziniergut entwickelten heißen Gasstrom vorgetrocknet und damit ein Zusammenbacken im Ofen vermieden bzw. ein eigener Vortrocknungsapparat erspart.The above-mentioned deficiencies are eliminated by the present invention. Namely, if you lead the material to be calcined through the gas or steam exhaust pipe to the Calciner closes, so the material introduced is immediately on the feed path pre-dried by the hot gas flow developed from the calcining material and thus caking in the oven is avoided or a separate pre-drying device is saved.
