Description
Die Erfindung betrifft. eine weitere Ausgestaltung des Dampfumwälzverfahrens für mittelbare Dampferzeugung nach Patent 8254t7 und bezweckt die Verminderung des Leistungsbedarfs derDampf -umwälzung. Die Einrichtung für das Verfahren, das Gegenstand dieser Zusatzanmeldung ist, ist in der Zeichnung dargestellt. Sie besteht aus einem befeuerten Überhitzer i, aus einem nicht feuerberührten Verdampfer 2, der über eine Heizfläche 3 mit Heißdampf beheizt wird, und aus der Umwälzeinrichtung 4. Der vom Überhitzer i kommende Heißdampf wird der Heizschlange 3 des Verdampfers 2 zugeführt. Während nach dem Hauptpatent der Entnahmedampf 'hinter dem Überhitzer abgezweigt wird, wird er hier hinter der Heizschlange 3, also vor der Umwälzeinrichtung abgezweigt und entweder als Sattdampf verwendet oder im gesonderten Überhitzer 6 nochmals überhitzt. Der im Verdampfer 2 erzeugte Naßdampf hat einen höheren Druck als der Dampf im Überhitzer i und kann in bereits bekannter `Vei.se nach Abb. I in der Strahlpumpe 4 entspannt werden und den Umwälzdampf bewegen oder nach Abb. II in einer Turbine 5 entspannt werden und die Umwälzpumpe .4 antreiben. Gegenüber -dem Hauptpatent ergibt sich bei der vorliegenden Erfindung der Vorteil, daß die Menge des Umwälzdampfes um die Entnahmemenge vermindert und entsprechend die Pumpenleistung verringert wird. Ferner ergibt die Anlage nach Abb. II den Vorteil, daß das Druckgefälle zwischen Verdampfer und Überhitzer vermindert wird dadurch, daß an Stelle der Strahlpumpe einTurbopumpensatz eingesetzt wird, dessen Wirkungsgrad besser ist als der der Strählpumpe; denn der Wirkungsgrad der Strählpumpe ist an sich nicht sehr hoch und sinkt stark ab, wenn das Mengenverhältnis vom getriebenen zum treibenden Dampf ansteigt.The invention relates to. another embodiment of the steam circulation process for indirect steam generation according to patent 8254t7 and aims to reduce the Power requirement of the steam circulation. The establishment for the procedure, the subject of this supplementary application is shown in the drawing. It consists of one fired superheater i, from a non-fire-contact evaporator 2, which has a Heating surface 3 is heated with superheated steam, and from the circulation device 4. The dated Superheater i superheated steam is fed to the heating coil 3 of the evaporator 2. While, according to the main patent, the extraction steam is branched off behind the superheater is, it is branched off here behind the heating coil 3, that is, in front of the circulation device and either used as saturated steam or superheated again in the separate superheater 6. The wet steam generated in the evaporator 2 has a higher pressure than the steam in the superheater i and can be relaxed in the jet pump 4 in the already known `` Vei.se '' according to Fig and move the circulating steam or expanded in a turbine 5 according to Fig. II and drive the circulation pump .4. Compared to the main patent results in the present invention, the advantage that the amount of circulating steam around the The withdrawal amount is reduced and the pump output is reduced accordingly. Further the system according to Fig. II has the advantage that the pressure drop between the evaporator and superheater is reduced by using a turbo pump set instead of the jet pump is used, the efficiency of which is better than that of the Strähl pump; because the The efficiency of the Strähl pump is not very high per se and drops sharply when the ratio of the driven to the driving steam increases.
