Description

Dampfkraftanlage mit Wärmespeicher. Es ist bekannt, Kraftmaschinen anzuzapfen und den nicht durch die Belastung in Anspruch genommenen Teil des Dampfes der Kraftmaschine als Heizdampf oder zum Vorwärmen des Speisewassers zu verwenden. Diese Anordnung hat jedoch den Nachteil, daß die Kraftmaschine einmal in Abhängigkeit von der Leistung und einmal in Abhängigkeit von der Entnahme geregelt werden muß. Sie führt leicht zu Unregelmäßigkeiten in der Krafterzeugung, wenn der Entnahmeregler Störungen erleidet. Man ist daher dazu übergegangen, der Hauptmaschine eine Hilfsmaschine zuzuordnen, welche mit Anzapfunben versehen ist, während die Hauptmaschine selbst ohne jede Anzapfung bleibt und lediglich in Abhängigkeit von der Belastung geregelt wird.Steam power plant with heat storage. It is known power machines to tap and the part of the steam not used by the load to use the engine as heating steam or to preheat the feed water. However, this arrangement has the disadvantage that the engine is once dependent must be regulated by the performance and once depending on the withdrawal. It easily leads to irregularities in power generation, if the withdrawal regulator suffers malfunctions. One has therefore moved on to the main engine to assign an auxiliary machine, which is provided with taps, while the Main machine itself remains without any tapping and is only dependent on the load is regulated.

Die Erfindung besteht darin, die Vorwärmermaschine mittels einer Düse auf konstante Durchflußmenge, die nach Bedarf verändert werden kann, einstellen. zu lassen und mit Kondensation zu versehen. Findet eine Entnahme von Dampf nicht statt, so fließt auch weiterhin die eingestellte Dampfmenge durch die Maschine und wird in mechanische oder elektrische Leistung umgesetzt. Die Teilung der Dampfanenge in Arbeitsdampf und Vorwärmerdampf kann in Abhängigkeit von der Leistung oder von dem Bedarf an Vorwärmerdampf geregelt werden. Die Entnahmemaschine kann parallel zu der gesamten Hauptmaschine angeordnet werden; sie kann aber auch bei einer mehrstufigen Hauptmaschine parallel zu einem Teildruckgefälle arbeiten.The invention consists in the preheating machine by means of a nozzle Set to constant flow rate, which can be changed as required. to leave and to provide with condensation. Does not find a withdrawal of steam instead, the set amount of steam continues to flow through the machine and is converted into mechanical or electrical power. The division of the vapors in working steam and preheater steam, depending on the power or on the need for preheater steam can be regulated. The removal machine can run in parallel be arranged to the entire main machine; but it can also be used with a multi-level Main machine work parallel to a partial pressure gradient.

Ausführungsformen der Anordnung nach der Erfindung sind in der Zeichnung wiedergegeben.Embodiments of the arrangement according to the invention are in the drawing reproduced.

Der Dampferzeuger i speist über die Dampfleitung a die Hauptturbine 3, die in bekannter Weise lediglich in Abhängigkeit von der Belastung geregelt wird. Parallel zur Hauptturbine ist erfindungsgemäß die Kondensationsturbine 4 angeordnet, der durch eine Düse 5 eine konstante, aber einstellbare Dampfmenge zugeführt wird. Die Turbine 4 ist in zwei Stutzen 6 und 7 angezapft. Ihr Abdampf strömt ,n den Kondensator B. Der Entnahmedampf dient dazu, in Vonväxmern 9 und io das Speisewasser vorzuwärmen, welches durch die Pumpe i i dem Speisewasse rbeUälter i a entnommen und durch die beiden Vorwärmer 9 und i o in den Speichei 13 gedrückt wird.The steam generator i feeds the main turbine 3 via the steam line a, which is controlled in a known manner only as a function of the load. According to the invention, the condensation turbine 4 is arranged parallel to the main turbine, to which a constant but adjustable amount of steam is fed through a nozzle 5. The turbine 4 is tapped in two nozzles 6 and 7. Their exhaust steam flows into the condenser B. The extraction steam serves to preheat the feed water in Vonväxmern 9 and io, which is generally taken from the feed water tank by the pump ii and pressed into the storage tank 13 by the two preheaters 9 and io.

Bei der Anordnung nach der Abb. a ist die Vorwärmerturbine 4 nicht der gesamten Hauptturbine, sondern der Niederdruckstufe derselben parallel geschaltet. Die Anordnung bleibt im übrigen die gleiche.In the arrangement according to Fig. A, the preheater turbine 4 is not the entire main turbine, but the low-pressure stage of the same connected in parallel. The arrangement remains the same for the rest.

Die Anordnung nach der Erfindung hat den Vorteil, daß ständig eine laufende Reservemaschine zur Verfügung steht bei wirtschaftlichster Ausnutzung des Leerlaufdampfes.The arrangement according to the invention has the advantage that constantly one running reserve machine is available with the most economical utilization of the Idle steam.
