Description

Vorrichtung zur Regelung des Dampfeintritts in einen Wärmespeicher. Um in Dampfkraftanlagen mit schwankendem Dampfverbrauch eine gleichmäßige Belastung der Dampferzeuger zu erzielen, ordnet man vor den Verbrauchern einen Wärmespeicher an, der bei sinkender Belastung den überschüssigen Dampf aufnimmt. Bei bekannten Anlagen wird das Eintrittsventil zum Speicher in Abhängigkeit vom Druck in der Verbraucherleitung gesteuert, derart, daß bei abnehmendem Dampfverbrauch, also bei steigendem Druck, in der Leitung das Eintrittsventil zum Speicher öffnet. Diese Vorrichtungen, welche die Speicherung des Dampfes regeln, arbeiten nicht immer befriedigend, da bereits geringe Abweichungen vom Normaldruck zur Speicherung führen,! die unter Umständen unerwünscht ist. Erfindungsgemäß wird die Speicherung in Abhängigkeit von der in der Verbraucherleitung strömenden Dampfmenge eingeleitet. Der Dampfeintritt zum Speicher wird dabei folgendermaßen gesteuert: Wird die Dampfgeschwindigkeit in der Dampfleitung durch Rückgang des Dampfverbrauches geringer, so wird der überschußdampf dem Speicher zugeführt, bis die Strömungsgeschwindigkeit wieder annähernd ihren vorgeschriebenen Wert erreicht hat. Um Pendelungen zu vermeiden, kann man dabei die Einrichtung treffen, daß der Eintritt des überschußdampfes in den Speicher erst dann öffnet, wenn die Strömungsgeschwindigkeit um ein gewisses Maß gegenüber ihrem Normalwert gesunken ist.Device for regulating the entry of steam into a heat accumulator. To ensure an even load in steam power plants with fluctuating steam consumption To achieve the steam generator, a heat accumulator is arranged in front of the consumers which absorbs the excess steam as the load decreases. At acquaintances In systems, the inlet valve to the accumulator is dependent on the pressure in the consumer line controlled in such a way that with decreasing steam consumption, i.e. with increasing pressure, the inlet valve to the storage tank opens in the line. These devices, which regulate the storage of the steam, do not always work satisfactorily, because even small deviations from normal pressure lead to storage! the under Circumstances is undesirable. According to the invention, the storage is dependent initiated by the amount of steam flowing in the consumer line. The steam entry to the memory is controlled as follows: The steam speed in the steam line due to the decrease in steam consumption, the excess steam is reduced fed to the memory until the flow rate again approximates its has reached the prescribed value. You can do this to avoid swings meet the device that the entry of the excess steam into the memory only then opens when the flow rate is a certain amount compared to her Normal value has decreased.

Die Vorrichtung nach- der Erfindung ist in einer Ausführungsform in der Zeichnung veranschaulicht.The device according to the invention is in one embodiment in illustrated in the drawing.

r ist eine Dampfleitung, von der durch ein Drosselventil 2' Dampf in das Dampfnetz 3 strömt, an welches Verbraucher mit schwankendem Dampfverbrauch angeschlossen sind. Geht in dieser Dampfleitung 2 der Dampfverbrauch zurück, so schließt zunächst in Abhängigkeit von dem zunehmenden Druck an der Meßstelle 4 das Ventil 2 etwas. Die Abhängigkeit der Ventilstellung von dem Druck in der Leitung 3 ist durch die Punktierte Linie 5 angedeutet. Wenn die durch 2 gehende Dampfmenge unter ein bestimmtes Maß gesunken ist, so wird unter dem Einfluß der Meßdüse 6 das Ventil 7 geöffnet, so daß der Überschußdainpf in den Speicher 8 strömen kann. Die Abhängigkeit des Speicherventils 7 von der Düse 5 ist durch die. punktierte Linie g angedeutet. Die Anordnung nach der Erfindung bietet den Vorteil, daß erst größere Abweichungen vom normalen Dampfverbrauch die Speicherung einleiten, während die betriebsmäßig auftretenden gelingen Schwankungen keinen Einfluß auf den Speicher ausüben.r is a steam line from which steam is passed through a throttle valve 2 ' flows into the steam network 3, to which consumers with fluctuating steam consumption are connected. If the steam consumption decreases in this steam line 2, then so closes the first depending on the increasing pressure at the measuring point 4 Valve 2 something. The dependence of the valve position on the pressure in the line 3 is indicated by the dotted line 5. When the amount of steam going through 2 has fallen below a certain level, then under the influence of the measuring nozzle 6, the Valve 7 is open so that the excess water can flow into the memory 8. the Dependence of the storage valve 7 on the nozzle 5 is through the. dotted line g indicated. The arrangement according to the invention offers the advantage that only larger Deviations from normal steam consumption initiate storage, while the Fluctuations that occur during operation have no effect on the memory exercise.
