Description
Die -'eichen Verhä'tnisse ergeben. sich im wesentlichen auch, wenn in b2kannter Weize der Flüssigkeitsin#alt: einer Abschei.detrornrr;el in der Weise aufgeteilt wird, daß ein Teil der abgeschiedenen Flüssigkeit verdampft und nur der übrigbleibende Flüssigkehsteil aus der Anlage abgeführt wird. Auch in die-E#em Fall ist der Beginn der überhitzung an dem Austrittspunkt aus dem Abscheider festgelegt, sc> daß der Überhitzer trockenen Dampf erhält und seine Tempe a-ur unhe.influßt bleibt.The -'eal circumstances result. essentially also, if in well-known wheat of the liquid in # old: a separating mandrel in the manner is divided so that part of the separated liquid evaporates and only the Remaining liquid part is discharged from the system. Even in that case the beginning of the overheating is determined at the exit point from the separator, sc> that the superheater receives dry steam and its temperature is unhindered remain.
DemgegenüLer wird ge-mäß der Erfindung nur eine Teilmenge des Wassers durch den Abscheider aus dem Arbeitsmit-,elkreislauf abgeführt, während eine andere Teilmenge des Wassers mit dem Dampf in einen dem überhi-zer vorgeschaltetc#n Nachverdampfer weiterströmt. Die Wasserteilmengc, die mit dem Dampf in den * Nachverdampfer weiter -clangt, beeinflußt die Temperatur im überhitzer derart, daß sie einen Maßstab auch für die Vargänge ergibt, die sich vor dem Abscheider in der Erwärmungszone und in der Verdampfungszone abspic'en. Es können somit die Vo-rgän-e vor dem Abscheider in Ab- hängigkeit von der Temperatur hinter dem Abscheider geregelt werden.In contrast, according to the invention, only a portion of the water is removed from the working fluid circuit by the separator, while another portion of the water flows with the steam into a re-evaporator upstream of the superheater. The Wasserteilmengc, further -clangt with the vapor in the reboiler *, affect the temperature in the superheater such that it gives a measure for the Vargänge that abspic'en located upstream of the separator in the heating zone and in the evaporation zone. It can thus be controlled dependence on the temperature downstream of the separator before the separator into waste the Vo-rgän-e.
Auf der Zeichnung ist als Ausführungsbeispiel eine Dampfkraftanlage mit einem Hochdruckdurchflußröhren2ampf'erze,uger-, e-:ner Kraftmaschine, einem Kandensator und einer Regelanerdnung gemäß der Erfindung ge-Dem Dampferzeuger i wIrd durch die Speiseleitung 2 Speisewasser zugeführt, das zuerst in, den Vo-ri#,ärmer 3 gelangt und im anschließenden Teil,4 bis auf einen Rest verdampft wird. Der Dampf und der Wasserrest strömen durch die Leitung 5 in den Abscheider 6. Eine Teilmenge des in den Abscheider gelangenden Wassers wird, mittels der Regelvo.rrichtun- i i, z. B. in Ab' hängigkeit von der Leistung des Dampferzeugers eingestellt, durch die Leitung 9 in den Ablauf i o fortgeführt.In the drawing, as an exemplary embodiment, a steam power plant with a high-pressure flow tube 2ampf'erze, uger-, e-: ner engine, a Kandensator and a Regelanerdnung according to the invention -ri #, poorer 3 arrives and in the subsequent part, 4 is evaporated except for a remainder. The steam and the remaining water flow through the line 5 into the separator 6. B. Ab 'dependency set by the performance of the steam generator continues through line 9 into the drain io.
Der Dampf und die noch übrigbleibende Teilmenge des. Wassers gelangen durch die Leitung7 in die anschließende Heizfläche8. Ein erster Teil dieser 1-I#rizfl,4cheS d':ent als N N achverdampfer ', ein zweiter als Gbierhitzer.The steam and the remaining portion of the water get there through the line 7 into the subsequent heating surface 8.

Der überhitzte Hüchdruckdampf strömt durch die Leitung 13 in die Hochdruckkraftmasehine ;Z 14, durch die Leitung r5 in die NIederdruck-I maschine 16 und dann in den Kondensator 21. Das.

Zu.The superheated high-pressure steam flows through line 13 into the high-pressure engine ; Z 14, through line r5 into the low-pressure machine 16 and then into the condenser 21. The. Condensate is led into the feed tank and into the vo # n ", arnier35. The heated feed water gets into the steam generator i. To.
zun- der Spelsewasserverluste, die du-eh Liii dichte Stopfbüchsen o.dgl. entstehen, kann Kondensat oder gereinigt-es Rohwasser als Ersatzwasser verwendet werden. Die Pumpe4# fördert nach -Maßgabe der Verluste dai; Ei. satzwasser in den Speisehehälter3o.First of all, spilling water losses, the you-eh Liii tight stuffing boxes or the like. can arise, condensate or purified - it uses raw water as substitute water will. The pump4 # delivers according to the losses dai; Egg. set water in the Pantry holder3o.
Kurz hinter dem Abscheider ist ein Wärm-, -aufnehmer 70 bekannter Arte:*ngeschaltet, dc: über die Leitung71 und den Scrvomotor72 auf d-e Wärm:e- oder- Wasserzufuhr zum Dampferzeuger so einwirkt, daß der Dampf. der in den Abscheider6 gelangt, immernoch eine entsprechende Wassermenge aufweist.Shortly after the separator there is a heat sensor 70 of known types, which acts via the line 71 and the scrvomotor72 on the heat or water supply to the steam generator in such a way that the steam acts. which gets into the separator6, still has a corresponding amount of water.
Der Brenner51 erhält die VerbrennungS luft durch die Leitung 52 und den Brennstoff durch die Leitung53 zugeführt. Zur Rege lung des Feuers dient ein-2 in die Luftleitung 52 eingeschaltete Vorrichtung58 und 2ine in die Brennstoffleitung 53 eingeschaltete Vorrichtung59. Beide Vorrichtungen können in Abhängigkeit von nicht eingezeichneten Impulsgebern in bekannter Weise z.B. in Abhänggigkeit von der aus dem Abscheider ab-Öleführten Wassermenge beeinflußt werdei.-The burner 51 receives the combustion air through the line 52 and the fuel through the line 53 supplied. A device 58 connected to the air line 52 and a device 59 connected to the fuel line 53 serve to regulate the fire. Both devices can be influenced in a known manner as a function of pulse generators not shown, for example as a function of the amount of water discharged from the separator.
