Das entgaste Speisewasser wird einerseits über eine Niederdruckspeisewasserpumpe (10) und vorzugsweise einen Economizer (1) in eine Niederdrucktrommel (8) und anderseits über eine Hochdruckspeisewasserpumpe (13) und einen Hochdruckeconomizer (3) in eine Hochdrucktrommel (9) gefördert Es können auch mehrere Pumpen in beiden Systemen vorhanden sein. Aus der Niederdrucktrommel (8) wird das Wasser über die Niederdruckumwälzpumpe (14) in einen Niederdruckverdampfer (3) eingeleitet, aus dem der Niederdruckdampf der Niederdrucktrommel (8) auf dem strichpunktierten Weg zugeführt wird. Der Dampf wird über den Niederdrucküberhitzer (5) dem Niederdnickteil (18) einer Dampfturbine (39) zugeführtIn the known systems, the supercooled condensate can be pumped into the feed water tank (7) using a condensate pump (20), possibly via a preheater (not shown) and a degasser (38), as indicated by dash-dotted lines. The degassed feed water is conveyed on the one hand via a low-pressure feed water pump (10) and preferably an economizer (1) into a low-pressure drum (8) and on the other hand via a high-pressure feed water pump (13) and a high-pressure economizer (3) into a high-pressure drum (9) be present in both systems. From the low-pressure drum (8), the water is introduced via the low-pressure circulation pump (14) into a low-pressure evaporator (3), from which the low-pressure steam is fed to the low-pressure drum (8) on the dash-dotted path. The steam is fed to the low-pressure section (18) of a steam turbine (39) via the low-pressure superheater (5)
Aus der Hochdrucktrommel (9) wird das Wasser über die Hochdruckumwälzpumpe (11) dem Hochdruckverdampfer (4) zugeführt, aus welchem der Dampf auf dem strichpunktierten Weg in die Hochdrucktrommel (9) gelangt. Aus dieser Trommel wird sodann Dampf über den strichpunktierten Weg in den Hochdrucküberhitzer (6) eingeführt, aus dem der Hochdruckdampf in den Hochdruckteil (17) der Dampfturbine (39) gelangt.From the high-pressure drum (9), the water is fed via the high-pressure circulation pump (11) to the high-pressure evaporator (4), from which the steam reaches the high-pressure drum (9) in a dash-dotted way. Steam is then introduced from this drum via the dash-dotted path into the high-pressure superheater (6), from which the high-pressure steam reaches the high-pressure part (17) of the steam turbine (39).

Diese Aufgabe wird bei einem Dampferzeuger der eingangs erwähnten Art dadurch gelöst, daß erfindungsgemäß die Dampftrommel, vorzugsweise eine Niederdrucktrommel, mit einer integrierten thermischen Entgasung versehen, die Funktion eines Speisewasserbehälters hat Dadurch entfällt die im konventionellen System erforderliche Speisewasserpumpe. Außerdem wird anstelle der üblichen Anordnung eines Speisewasserbehälters und einer Niederdrucktrommel nur ein Behälter vorgesehen, welcher sowohl die Funktion des Speisewasserbehälters als auch die Funktion der Niederdrucktrommel ausübtThis object is achieved in a steam generator of the type mentioned at the outset in that, according to the invention, the steam drum, preferably a low-pressure drum, is provided with integrated thermal degassing and has the function of a feed water tank. This eliminates the feed water pump required in the conventional system. In addition, instead of the usual arrangement of a feed water container and a low pressure drum, only one container is provided, which performs both the function of the feed water container and the function of the low pressure drum
