isothermischer Expansion.isothermal expansion.
Die Erfindung betrifft Turbinenanlagen mit stufenweiser Expansion, bei denen zwischen den einzelnen Stufen zur Erzielung einer annähernd isothermischen Expansion Wiedererhitzer angeordnet sind. Bei derartigen Anlagen bildet der für die Wiedererhitzung dienende Wärmebetrag einen großen Teil der Gesamtwärme. Es ist deshalb notwendig, für diese Wiedererhitzer eine Anordnung zu treffen,The invention relates to turbine systems with gradual expansion, in which between the individual stages to achieve an approximately isothermal expansion reheater are arranged. In such systems, the amount of heat used for reheating forms a large part of the Total heat. It is therefore necessary to make an arrangement for these reheaters,
ίο die eine wirtschaftliche Ausnutzung ihrer Heizanlagen gestattet.ίο making an economic use of their Heating systems permitted.
Die Wiedererhitzer werden zu diesem Zwecke unmittelbar im Zuge der Heizgase vor wenigstens einem Teil der eigentlichen Kesselelemente bezw. Wassererhitzer angeordnet, in der Weise, daß die Heizgase der Feuerung zunächst durch die Wiedererhitzer und dann durch Kessel- oder dergl. Elemente strömen. Die Wärme der Heizgase wird auf diese Weise voll ausgenutzt. Die Heizgase besitzen beim Durchströmen durch die Wiedererhitzerelemente die erforderlich hohe Temperatur und werden dann in den folgenden Kessel elementen weiter verwandt. Es wird als bekannt vorausgesetzt, die Wiedererhitzer im Zuge der Feuerungsgase anzuordnen. Bei den bekannten Anordnungen lagen die Wiedererhitzer jedoch zum größten Teil am Ende des Feuerungskanales an einer Stelle, wo die Heizgase bereits den größten Teil ihrer Wärme abgegeben haben. Eine derartige Anordnung eignet sich nicht zur Erzielung möglichst vollkommener isothermischer Expansion bei Turbinen mit vielen Stufen, für die die vorliegende Erfindung gedacht ist. .For this purpose, the reheaters are activated directly in the course of the heating gases BEZW before at least part of the actual boiler elements. Water heater arranged, in such a way that the heating gases of the furnace first through the reheater and then through the boiler or the like. Elements stream. The heat of the heating gases is fully utilized in this way. The heating gases have the required high temperature when flowing through the reheater elements and are then used in the following boiler elements. It will assumed to be known to arrange the reheaters in the course of the combustion gases. at However, the reheaters were largely at the end of the known arrangements of the firing duct at a point where the heating gases already have most of their heat have given up. Such an arrangement is not as suitable as possible for achieving this perfect isothermal expansion in turbines with many stages for which the present Invention is intended. .
Auf der Zeichnung ist die Erfindung beispielsweise veranschaulicht; es sind:The invention is illustrated by way of example in the drawing; there are:
Fig. ι Seitenansicht der allgemeinen Anordnung einer vollständigen, der Erfindung entsprechenden Anlage,Fig. Ι side view of the general arrangement of a complete, the invention corresponding system,
Fig. 2, 3 und 4 Schnitte nach den Linien X-X, Y-Y, bezw. Z-Z der Fig. 1.Fig. 2, 3 and 4 sections along the lines XX, YY, respectively. ZZ of FIG. 1.
Bei der Verbund- oder mehrstufigen Druck-Dampfturbine α (Fig. 1) bekannter Bauart ist jede Stufe in der Weise getrennt, daß der aus der ersten Stufe auspuffende Dampf durch einen Wiedererhitzer dem Einlasse der zweiten Stufe zugeführt wird, dessen Auspuff zu einem zweiten Wiedererhitzer geht und so fort, so daß nach jeder Expansionsstufe bis zu, dem schließlichen Auspuffe eine Wiedererhitzung stattfindet. Die Turbine sitzt auf einer wagerechten Welle und die Wiedererhitzer befinden sich unterhalb des Turbinenkörpers. .In the composite or multistage pressure steam turbine α (Fig. 1) of known design, each stage is separated in such a way that the steam exhausted from the first stage is fed through a reheater to the inlet of the second stage, the exhaust of which is fed to a second reheater goes and so on, so that after each expansion stage up to the eventual exhaust a reheating takes place. The turbine sits on a horizontal shaft and the reheaters are located below the turbine body. .
Die in Form von Rohrelementen ausgebildeten Wiedererhitzer b, c sind in dem Feuerungskanal d der Heizanlage, und zwar vor den Kesselelementen e,f, k, I untergebracht. Die letzten Elemente h, i des Kessels liegen gemäß Fig. ι vor den Wiederethitzern. Die Elemente h, i könnten jedoch auch hinter den Wiedererhitzern oder parallel zu diesen liegen und dann durch eine besondere Feuerung beheizt werden, deren Abgase ebenfalls durch die Kessel elemente e,f,k,l streichen würden. The reheaters b, c , designed in the form of tubular elements, are housed in the firing duct d of the heating system, in front of the boiler elements e, f, k, I. The last elements h, i of the boiler are in front of the reheaters as shown in FIG. The elements h, i could, however, also lie behind the reheaters or parallel to them and then be heated by a special furnace whose exhaust gases would also pass through the boiler elements e, f, k, l .
Es ist zweckmäßig, Kesselelemente e,fi k, I und Uberhitzerelemente h, i anzuordnen, die einander ähnlich sind. Diese Elemente bestehen aus einer oberen und einer unteren Trommel unter Verbindung durch eine große Anzahl fast senkrechter Rohre, die quer durch den Kanal d gehen und gegebenenfalls im Wege der Abgase liegen.It is useful to arrange boiler elements e, fi k, I and superheater elements h, i that are similar to one another. These elements consist of an upper and a lower drum connected by a large number of almost vertical pipes which pass transversely through the channel d and which may be in the way of the exhaust gases.

ίο Anordnung zu der Feuerungsanlage vorteilhaft durch ein Rohr t, das durch den Fuchs der Anlage hindurchgeführt wird, so daß die Luft im Gegenstrom zu den Abgasen vorgewärmt wird.ίο arrangement to the furnace advantageously by a pipe t, which is passed through the fox of the system, so that the air is preheated in countercurrent to the exhaust gases.
Nach Fig. 1 ist in Verbindung mit der Auspuffleitung m der Turbine ein Schlangenrohrgenerator η vorgesehen, um die Wärme des Auspuffdampfes zu gewinnen. Die Wasserzufuhr zu diesem Regenerator erfolgt von dem Kondensator u oder von einem Warmwasserbehälter aus durch das Rohr 0. Das Ende ρ des Regenerators, das sich der Turbine am nächsten befindet, ist durch ein Rohr r mit dem Wassererhitzer verbunden, so daß die in dem Auspuff der Turbine enthaltene Wärme zum Teil wieder in das arbeitende Mittel zurückgebracht wird. Diese Anordnung des Regenerators bildet jedoch keinen Teil vorliegender Erfindung.According to Fig. 1, a coiled tube generator η is provided in connection with the exhaust line m of the turbine in order to obtain the heat of the exhaust steam. Water is supplied to this regenerator from the condenser u or from a hot water tank through pipe 0. The end ρ of the regenerator closest to the turbine is connected to the water heater by a pipe r so that it is in the exhaust The heat contained in the turbine is partly returned to the working medium. However, this arrangement of the regenerator does not form part of the present invention.
