Description
in den Überhitzer 6. 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.
