Description
Bei der Herstellung von Schmelzzement im Drehrohrofen hat sich die unangenehme Erscheinung gezeigt, daß das Schmelzgut an der Stelle im Ofen, wo es eben zu schmelzen be-. ginnt oder teigig wird, stark zum Anbacken an das Ofenfutter neigt. Es bildet sich dann der gefürchtete Ansatz, der zur Folge hat, daß sich der Zug im Ofen, verschlechtert, die Verbrennung unvollkommen wird, mithin dieDuring the production of molten cement in the rotary kiln, the unpleasant phenomenon has become shown that the melt material at the point in the furnace where it is about to melt. greases or becomes doughy, has a strong tendency to stick to the oven lining. It then forms the dreaded approach, which has the consequence that the draft in the furnace worsens, the Combustion becomes imperfect, hence the
ίο Wirtschaftlichkeit der Anlage in Frage gestellt ist. Der Ofenbetrieb muß dann unterbrochen werden, damit man den Ansatzring auf mechanische oder sonstige Art und Weise entfernen kann,ίο The profitability of the system is called into question is. The furnace operation must then be interrupted so that the shoulder ring can be mechanically or otherwise can remove
is In der Praxis hat sich nun gezeigt, daß man all diesen Schwierigkeiten aufs einfachste dadurch entgehen kann, daß man den Ofen an der Stelle der Ansatzbildung in beliebigem Ausmaß erweitert. Dadurch wird is In practice it has now been shown that the easiest way to avoid all these difficulties is to use the The furnace is expanded to any extent at the point of formation. This will
ao erreicht, daß das Rohgut im Augenblick der Verflüssigung über die so gebildete Böschung hinunterstürzt und infolge dieser schnellen Bewegung nicht anbacken kann. Auch bei Ansammlung größerer Klumpen in der Erweiterung erfolgt keine Verengung des Ofenrohrquerschnittes und kein Anbacken, da die Klumpen bei der Drehung des Drehofens durch ihr Eigengewicht abfallen. Je nach den Betriebsverhältnissen wird die Erweiterung nach der Schmelzzone zu gerade abgesetzt oder mit einem allmählichen Übergang versehen. ao achieved that the raw material at the moment of Liquefaction falls down over the embankment thus formed and, as a result, rapid Movement cannot stick. Also at Accumulation of larger lumps in the enlargement does not lead to a narrowing of the stove pipe cross-section and no caking, as the lumps as the rotary kiln rotates fall off by their own weight. Depending on the operating conditions, the expansion too straight after the melting zone or provided with a gradual transition.
