Description

Anzapfturbine mit Dampfspeicher. Die Erfindung betrifft eine Anzapfturbine, die zwecks möglichster Gleichhaltung der Dampferzeugung mit einem parallel zur Heizleitung geschalteten Dampfspeicher verbunden ist.Extraction turbine with steam storage. The invention relates to a bleed turbine, for the purpose of keeping the steam generation as equal as possible with a parallel to the heating cable switched steam accumulator is connected.

Bei derartigen Turbinen war bisher die Turbinenkammer, aus der der Dampfentnommenund dem Speicher zugeführt wurde, stets mit dem Speicherraum verbunden, so daß in der Entnahmekammer stets der starke schwankende Speicherdruck herrschte. Dies hat den Nachteil, daß die beiden der Entnahmestelle benachbarten Turbinenstufen dauernd mit stark schwankendem Gefälle arbeiten, wodurch ihr Wirkungsgrad beeinträchtigt wird. Außerdem muß, da der Speicherdruck stets höher e-ls der Heizdampfdruck sein muß und der gesamte Entnahmedampf in den Speicherraum tritt, immer ein sehr großes Druckgefälle zwischen Entnahmestelle der Turbine 'und Heizleitung vorhanden sein. Der damit verbundene Drosselverlust ist für Krafterzeugungszwecke vollständig verloren.In such turbines, the turbine chamber from which the Steam has been withdrawn and fed to the storage tank, always connected to the storage room, so that the strongly fluctuating storage pressure always prevailed in the removal chamber. This has the disadvantage that the two turbine stages adjacent to the extraction point continuously work with strongly fluctuating slopes, which affects their efficiency will. In addition, since the storage pressure is always higher, the heating steam pressure must be e-ls must and the entire extraction steam enters the storage space, always a very large one There must be a pressure gradient between the extraction point of the turbine and the heating line. The associated throttle loss is completely lost for power generation purposes.

Gemäß der Erfindung wird dieser Nachteil dadurch verringert, daß in die Verbindungsleitung, zwischen Entnahmestelle und Speicher, Organe eingebaut werden, die je nach dem Verhältnis des gebrauchten zur verfügbaren Abdampfmenge die Entnahmestelle mit der Heizleitung oder mit dem Speicher oder mit beiden zugleich verbinden. Hierdurch wird erreicht, daß bei einem die verfügbare Anza.pfmenge übersteigenden Heizdampfbedarf der ganze Anzapfdampf ohne wesentlichen Druckverlust aus der Turbine und der Mehrheizdampfbedarf aus dem Speicher in die Heizleitung übertritt, während bei einer den Heizdampfbedarf übersteigenden verfügbaren Abdampfmenge in die Heizleitung nur der erforderliche Heizdampf eintritt, wobei sich der Druck in der Entnahmekammer der Turbine so weit anstaut, bis er den Speicherdruck; etwas überschreitet, worauf der überschüssige Anzapfdampf in den Speicher übertritt. Der Vorteil dieses Verfahrens besteht darin, daß etwa während der halben Betriebszeit zwischen Entnahmekammer und Heizleitung kein wesentlicher Drosselverlust vorhanden ist.According to the invention, this disadvantage is reduced in that in the connecting line between the extraction point and the storage facility, organs are installed, depending on the ratio of the used to the available Amount of evaporation the tapping point with the heating tape or with the storage tank or with both at the same time associate. What is achieved hereby is that, in the case of one, the available counting quantity is exceeded The entire bleed steam is required for heating steam without any significant pressure loss from the turbine and the additional heating steam requirement from the storage unit transfers into the heating line while in the case of an available amount of exhaust steam exceeding the heating steam requirement in the heating cable only the required heating steam enters, whereby the pressure in the extraction chamber the turbine backs up until it reaches the accumulator pressure; something transcends on what the excess bleed steam passes into the storage tank. The advantage of this procedure consists in the fact that during about half the operating time between the removal chamber and heating cable there is no significant throttle loss.

In der Zeichnung ist eine Ausführungsform beispielsweise wiedergegeben. Vom Kessel k tritt eine angenähert gleichbleibende Dampfmenge in die Leitung a, von wo sie durch. das Ventil oder die Ventile u in die Turbine t tritt und in der Hochdruckstufe Arbeit leistet. Aus der Entnahmekammer e tritt ein Teil durch die Überströmventile x, von denen in der Zeichnung nur eins wiedergegeben ist, in den Niederdruckteil und den Kondensator. Der Rest tritt durch den Entnahmestutzen. f in die Leitung c. Ist der Heizdampfbedarf gleich der Entnahmemenge, so ist Ventil v ganz offen und läßt den ganzen Entnahmedampf durch die Leitung b in die Heizleitung h treten. Ist der Heizdampfbedarf größer als die Entnahmemenge, so fließt außerdem der Rest aus dem Speicher s durch das Ventil w in die Heizleitung lt. Ist der Heizdampfbedarf kleiner als die Entnahmemenge, so drosselt Ventil v so weit, daß nur der gebrauchte Teil der Entnahmemenge in die Heizleitung k treten kann; der Druck in der Leitung c und der Kammei e staut sich dann so lange, bis er so groß geworden ist, daß der überschüssige Dampf durch das Rückschlagventil r in den Speicher s treten kann. Ist der gesamte Dampfverbrauch der Turbine kleiner als die vom Kessel gelieferte Dampfmenge, so schließen sich der Reihe nach die Ventile u, , während Ventil y sich öffnet und den überschüssigen Dampf aus der Leitung a durch die Leitung g in den Speicher s übertreten läßt.In the drawing, an embodiment is shown for example. An approximately constant amount of steam passes from the boiler k into line a, from where it passes through. the valve or valves u enters the turbine t and does work in the high pressure stage. A part of the extraction chamber e passes through the overflow valves x, only one of which is shown in the drawing, into the low-pressure part and the condenser. The rest comes through the extraction nozzle. f into the line c. If the heating steam requirement is equal to the withdrawal amount, valve v is completely open and allows all of the withdrawal steam to pass through line b into heating line h. If the need for heating steam is greater than the amount withdrawn, the remainder of the memory s also flows through the valve w into the heating line lt Heating cable k can occur; the pressure in the line c and the chamber e then accumulates until it has become so great that the excess steam can pass through the check valve r into the memory s. If the total steam consumption of the turbine is less than the amount of steam supplied by the boiler, valves u, close one after the other, while valve y opens and allows the excess steam from line a to pass through line g into memory s.

Gegenüber bekannten Verfahren hat das Verfahren nach der Erfindung, das auch bei Anzapfkolbenmaschinen angewendet werden kann, den Vorteil des verringerten Dampfverbrauches; bei Verwendung einer normalen Anzapfmaschine.Compared to known methods, the method according to the invention, which can also be used in dispensing piston machines, the advantage of the reduced Steam consumption; when using a normal tapping machine.
