Wird nun auch das Ventil 11 in der Abströmleitung 12 noch geschlossen, so kann der überhitzte Hochdruckdampf durch die Leitung 7 zu den Verbrauchsstellen gelangen.in the superheater 6. If the valve 11 in the outflow line 12 is still closed, the can superheated high-pressure steam pass through line 7 to the consumption points.

Die beiden Ventile 5 und 8 werden im normalen Betrieb durch den Druckimpulsgeber 13 so gesteuert, daß das Ventil 5 den Druck im Verdampfungsrohrsystem des Dampferzeugers dem Betriebsdampfdruck entsprechend gehalten wird, während das Ventil 8 unabhängig vom Impulsgeber 23 durch den Druckimpulsgeber 13 beeinflußt wird, wenn der Druck im Verdampfungsrohrsystem den in diesem normalen Strömungsdruck um ein bestimmtes Maß übersteigt. The two valves 5 and 8 are controlled in normal operation by the pressure pulse generator 13 so that that the valve 5 the pressure in the evaporation pipe system of the steam generator the operating steam pressure is held accordingly, while the valve 8 is independent of the pulse generator 23 by the pressure pulse generator 13 is influenced when the pressure in the evaporation pipe system exceeds the normal flow pressure in this by a certain amount.

DEUTSCHESGERMAN Die Erfindung betrifft eine weitere Verbesserung des Verfahrens zum Inbetriebsetzen eines mit Zwangdurchlauf des Arbeitsmittels betriebenen Dampferzeugers nach dem Patentanspruch 1 des Patents Nr. 968 350, bei welchem während des Anheizens Wasser aus dem Speisewasserbehälter durch einen Teil des Rohrsystems und zurück in den Behälter umgewälzt wird. Das Verfahren nach der Erfindung ist dadurch gekennzeichnet, daß das Wasser während der Inbetriebsetzung aus einem zwischen Verdampfer und Überhitzer angeordnetem, zur Flüssigkeitsabscheidung während des normalen Betriebs dienenden Abscheider zur Zurückführung in den Behälter entnommen wird.The invention relates to a further improvement of the method for starting up a with forced throughfeed the working fluid operated steam generator according to claim 1 of patent no. 968 350, in which water from the feed water tank through part of the pipe system during heating and circulated back into the container. The method according to the invention is characterized in that that the water during the start-up from a arranged between the evaporator and superheater, Separator used for liquid separation during normal operation for recirculation is removed into the container. Die Merkmale des Erfindungsgegenstandes sind an Hand eines Schaltbildes näher erläutert.The features of the subject matter of the invention are explained in more detail using a circuit diagram. Die in der Zeichnung dargestellte Zwangdurchlauf-Dampferzeugeranlage weist im wesentlichen einen Speisewasserbehälter 1, einen Vorwärmer 3, einen Verdampfer 31, einen zur Flüssigkeitsabscheidung während des normalen Betriebs dienenden Abscheider4 und einen Überhitzer 6 auf. Das Arbeitsmittel wird mittels der Speisepumpe 2. mit einem dem einzuhaltenden Betriebsdruck entsprechenden Förderdruck, durch das Rohrsystem 3, 31, 6 gepreßt und hierbei durch die Feuerung 20 im Brennraum 21 und durch die Rauchgase im Rauchgaszug 22 beheizt. Der hierbei entstehende überhitzte Dampf strömt durch die. Leitung 7 an nicht gezeichnete Verbrauchsstellen, aus denen das Arbeitsmittel in Form von Kondensat wieder zum Speisewasserbehälter 1 zurückgeführt werden muß.The once-through steam generator system shown in the drawing essentially has a feed water tank 1, a preheater 3 and an evaporator 31, a separator used for liquid separation during normal operation 4 and a superheater 6. The working fluid is supplied by means of the feed pump 2. with one to be complied with Operating pressure corresponding delivery pressure, pressed through the pipe system 3, 31, 6 and this heated by the furnace 20 in the combustion chamber 21 and by the flue gases in the flue 22. The resulting superheated steam flows through the. Line 7 to consumption points not shown, from which the Working medium in the form of condensate must be returned to the feed water tank 1.
