Description

Gaskraftanlage mit Kühlung des UnAauföles durch das zur Kühlung der Verbrennungsgase nötige Einspritzwasser Es sind Gaskraftanlagen für besondere Zwecke, z. B. Torpedos, bekannt, bei denen eine beständige Verbrennung unter Druck und eine Kühlung der Verbrennungsgase durch eingespritztes Wasser stattfindet. Diese verdampfte Wassermenge ist recht bedeutend und beträgt selbst bei Kühlung der Verbrennungsgase auf eine Arbeitstemperatur von 6oo bis 700'C etwa 50% der Abgasmenge; bei niedrigeren Temperaturen noch mehr.Gas power plant with cooling of the UnAauföles by the injection water necessary to cool the combustion gases. B. torpedoes are known in which a constant combustion under pressure and a cooling of the combustion gases by injected water takes place. This amount of evaporated water is quite significant and, even when the combustion gases are cooled to a working temperature of 600 to 700 ° C., amounts to about 50% of the amount of exhaust gas; even more at lower temperatures.

Andererseits erscheint es in manchen Fällen zweckmäßig, eine Umlaufschmierung anzuordnen und die mit dem öl abzuführende Reibungswärme in einen Ölkühler abzuführen. Dies erscheint besonders dann notwendig, wenn schnellaufende Turbinen mit Getrieben verwendet werden.On the other hand, it appears expedient in some cases to use circulating lubrication to be arranged and to dissipate the frictional heat to be dissipated with the oil in an oil cooler. This seems particularly necessary when high-speed turbines with gearboxes be used.

Die Erfindung bezweckt nun, die notwendige verhältnismäßig große Einspritzwassermenge zunächst schon für die Ölkühlung zu benutzen, um dadurch neinmal eine besondere Pumpe für dieses Kühlwasser zu sparen und andererseits die abgeführte Reibungswärme in Form einer Vorwärmung wieder in den Kreislauf einzuführen.The invention now aims to provide the necessary relatively large amount of injection water initially to be used for the oil cooling, which makes it a special one To save the pump for this cooling water and, on the other hand, the dissipated frictional heat to be reintroduced into the circuit in the form of preheating.

Die Erfindung besteht zu diesem Zwecke darin, daß das Einspritzwasser vor dem Einspritzen als Kühlmittel für das Umlauföl dient.The invention consists for this purpose in that the injection water serves as a coolant for the circulating oil prior to injection.

In den Abbildungen sind mehrere Ausführungsbeispiele gezeigt. Nach Abb. i kann der ölkühler A entweder an die Druckseite oder nach Abb. 2 an die Saugseite der Speisepumpe B, welche das Einspritzwasser in den Verbrennungsraum C zu fördern hat, verlegt werden. In ersterem Fall wird allerdings der ziemlich hohe Arbeitsdruck einen entsprechenden schweren ölkühler bedingen. Falls daher aus anderen Gründen :eine Zubringerpumpe erforderlich ist, würde der Ölkühler am besten nach Abb.3 an die Druckleitung von der Zubringerpumpe D zur Speisepumpe B eingebaut.Several exemplary embodiments are shown in the figures. According to Fig. I, the oil cooler A can be relocated either to the pressure side or, according to Fig. 2, to the suction side of the feed pump B, which has to convey the injection water into the combustion chamber C. In the first case, however, the rather high working pressure will require a correspondingly heavy oil cooler. If, for other reasons: a feed pump is required, the oil cooler would best be installed on the pressure line from feed pump D to feed pump B as shown in Fig.
