Das aus den Rohren b und c kommende Kondensat kann nach einer Stelle geleitet werden, wo man für nicht ganz reines Wasser Verwendung hat. Es kann beispielsweise zur Vorwärmung der in den Behälter I einzuleitenden Lauge benutzt werden. Aus dem Rohre D wird dagegen reiner Dampf von niedriger Spannung erhaben, welcher aus dem Kondensat des von dem Dampfkessel in den Behälter I eingeleiteten Hochdruckdampfes hergestellt ist.
Anstatt das Kondensat ans dem Rohre a zu benutzen, kann man, dem Raume 1'3 reines Wasser oder einen Flüssigkeit zuleiten, deren Abdampf keine schädlichen Eigen-
EMI2.1
Als eine besonders zweckmässige Ausführungsform soll erwähnt werden, dass das aus dem Rohre a kommende Kondensat nach dem Dampfkessel, welcher den Hochdruckdampf an das Rohr A liefert, zurückgeleitet und in denselben eingepumpt wird, während dem Raume r3 das Kondensat irgend einer Maschine, z. B. das vom Trockenapparat einer Papiermaschine, zugeführt wird. wobei der dem Rohre D entströmende Dampf zu dieser Maschine znrückgeleitot wird. Auf diese Weise kommen zwei getrennte Kreisläufe mit t'iuem zwischenliegenden Laugeeindampfungsapparat zustande.
Das vorliegende Verfahren. kann mit Vorteil in verschiedenen Industriezweigen, insbesondere auch in der Zuckerfabrikation angewendet werden.

The condensate coming from pipes b and c can be directed to a point where one can use water that is not entirely pure. It can be used, for example, to preheat the liquor to be introduced into the container I. On the other hand, pure steam of low voltage is raised from the pipe D, which is produced from the condensate of the high-pressure steam introduced into the container I by the steam boiler.
Instead of using the condensate from the pipe a, one can supply room 1'3 with pure water or a liquid whose vapor does not have any harmful properties.
EMI2.1
As a particularly expedient embodiment, it should be mentioned that the condensate coming from pipe a is returned to the steam boiler, which supplies the high-pressure steam to pipe A, and is pumped into the same, while the condensate of any machine, e.g. B. is fed from the dryer of a paper machine. the steam flowing out of the pipe D is returned to this machine. In this way, two separate circuits are created with a lye evaporation apparatus in between.
The present proceedings. can be used with advantage in various branches of industry, especially in sugar manufacturing.
