Erfindungsgemäß werden die Auspuffgase der Patronenabschußvorrichtung zum Anlassen teils der Turbinenainlage und teils der turbinengetriebenen Pumpe benutzt. Dadurch ist eine sofortige Betriebsbereitschaft gesichert, ohne daß es eines besonderen Antriebsmittels für die Hilfsturbine für den Antrieb der Pumpe bedarf. Gegebenenfalls kann zur Regelung des Brennstoffstromes ein elektrisch betätigtes, zur Brennstoffpumpe parallel geschaltetes Nebenchlußventil vorgesehen sein.The invention relates to a device for feeding the combustion chamber of a gas turbine plant with liquid fuel by means of a with the combustion chamber connected by. an auxiliary turbine driven pump in combination with a patrol launcher. According to the invention, the exhaust gases of the cartridge launcher for starting partly the turbine system and partly the turbine-driven pump. This ensures immediate readiness for operation, without it being anything special Drive means for the auxiliary turbine for driving the pump is required. If necessary, for Regulation of the fuel flow is electrically operated and connected in parallel to the fuel pump Shunt valve may be provided.
Eine beispielsweise Ausführunigsform des Erfindungsgiegenistandes zeigt die Zeichnung.An example of an embodiment of the inventive genius shows the drawing.
Eine Vorrichtung 1 zum Abfeuern einer Patrone ist mittete einer Leitung 2 mit einer Verbrennungisr kammer 3 verbunden, die mit einem durch eine Turbine angetriebenen Element 4 ausgerüstet fet. Die Kammer 3 steht über eine Leitung 5- mit einer Pumpe 6 in Verbindung.A device 1 for firing a cartridge is in the middle of a line 2 with a combustion isr Chamber 3 connected, which is equipped with a turbine-driven element 4 fet. The chamber 3 is connected to a pump 6 via a line 5.
Ein flüssigen Brennstoff enthaltender Behälter 7 as ist durch eine Rohrleitung 8 an den Einlaßstutzen der Pumpe 6 angeschlossen, während von dem Auslaßstutzen der Pumpe 6 eine Leitung 9 zu einemA container 7 as containing liquid fuel is connected by a pipe 8 to the inlet port of the pump 6, while from the outlet port the pump 6 a line 9 to a
elektrisch betätigten Kplbeiwentil no führt. Das Gehäuse des Ventils io hat außerdem zwei Anschlüsse oder Auslaßöffnungen 1,1 umd 12.electrically operated Kplbeiwentil no leads. That The housing of the valve io also has two connections or outlet openings 1.1 umd 12.
Der Anschluß 11 .führt zu eimern Regelventil 13, an das sich leine Leitung 14 nach der Verbrennungskammer 3, hin anschließt. Der andere Anschluß 112 steht mit einer Nebanschlußleitung 1.5 in Verbindung, die von dem Regelventil 1·$ zurück zu dem Behälter 7 führt.The connection 11 leads to pail control valve 13, to the leash line 14 after the combustion chamber 3, adjoins. The other port 112 is in connection with a bypass line 1.5, which from the control valve 1 · $ back to the Container 7 leads.
Das- Regelventil 13 steht unter Federbelastung, wobei es sich unter dem Druck des flüssigen Brennstoffes so einstellen kann, daß überschüssiger Brennstoff durch die Nebenschlußleitung 15 in den Behälter 7 zurückfließt. Die von der Pumpe 6 gelief erteThe control valve 13 is under spring load, whereby it can adjust itself under the pressure of the liquid fuel so that excess fuel flows back through the bypass line 15 into the container 7. The one supplied by the pump 6
Menge des flüssigen Brennstoffes übersteigt den normalen Bedarf. Infolgedessen wird die Federbelastung des Regelventils 13 so gewählt, daß die richtige Brennstoffmenge durch die öffnung 21 hindurchiströmen kann.1 The amount of liquid fuel exceeds normal requirements. As a result, the spring loading of the control valve 13 is selected so that the correct amount of fuel can flow through the opening 21. 1
Zur Betätigung der Einrichtung fet ein elektrischer Stromkreis vorgesehen,- welcher aus einer . Batterie ιό, einem Schalter 17 und einem Druckknopfschalter r& besteht.To operate the device, an electrical circuit is provided - which consists of a. Battery ιό, a switch 17 and a push button switch r & consists.
Beim Betrieb der Einrichtung wird zuerst der Schalter 17 geschlossen, so daß Strom zu dem Solenoid 19 gelangt, während das Kolbenventil 10 den Auslaß 12 verschließt und den Auslaß 1.1 öffnet. Daraufhin wird der Druckknopfschalter gedruckt, um die Patrone 20 abzufeuern, wodurch heiße Druckgase in die Verbrennungskammer 31 gelangen. Ein Tail dieser Gase dient dazu, um die Turbopumpe 6 anzutreiben, wodurch der Start dar Turbine 4 bewerkstelligt wird. Die Pumpe bewirkt auch ein Ansaugen von .flüssigem Brennstoff ausWhen operating the device, the switch 17 is closed first, so that current to the Solenoid 19 arrives while piston valve 10 closes outlet 12 and opens outlet 1.1. The push button switch is then pressed to fire the cartridge 20, causing hot Pressurized gases get into the combustion chamber 31. A tail of these gases is used to drive the turbo pump 6, thereby starting the turbine 4 is accomplished. The pump also draws in liquid fuel

- Nach dem ersten Start wird der Betrieb dieser beiden Elemente durch die Zufuhr von flüssigem Brennstoff in die Verbrennunigsbammer 3 fortgesetzt, und "ein Teil der aus dieser Kammer strö-- After the first start, the operation will be this both elements continued by the supply of liquid fuel into the combustion chamber 3, and "part of the flow from this chamber
mendan Verbrennungsgase treibt die Pumpe 6 an. Die aus der Verbrennungskammer.3, und der Turbopumpe 6 kommenden Abgase werden durch die Abgasleitungen 212: und 23 abgeführt.Mendan combustion gases drive the pump 6. The exhaust gases coming from the combustion chamber. 3 and the turbo pump 6 are passed through the exhaust lines 212 and 23 discharged.
Will man die Anlage abstellm,, so· ist es nur erforderlich, den Schalter 17 zu öffnen, wodurch das mittels eine'si Solenoids betätigte Ventil 10 die Leitung 11 verschließt und die Leitung 12 öffnet. Dadurch wird die Zufuhr vom flüssigem Brennstoff zu dar Verbrennungskammer abgesperrt, während der dom Behälter 7 entnommene Brennstoff durch die Nabenschlußleitung während des letzten Auslaufens der Pumpei 6 wieder in den Behälter 7 zurückbefördert· wird.If you want to shut down the system, that's just it required to open the switch 17, whereby the solenoid operated valve 10 the Line 11 closes and line 12 opens. This shuts off the supply of liquid fuel to the combustion chamber while The fuel removed from the dome container 7 is returned to the container 7 through the hub line during the last time the pump 6 ran out is transported back.
Gegebenenfalls können der Verbrennungskammer Luft oder andere oxydierende Gase zugeleitet werden, um .die Pumpe in der oben beschriebenen Weise zu betreiben. Nachdem dia Pumpe die Verbrennungskammer mit flüssigem Brennstoff gelspeist hat, wird das. Gemisch aus Brennstoff und oxydierendem Gas gezündet. Nachdem dann eine stabile Verbrennung eingetreten ist, wird die Zufuhr des oxydierenden Gases abgestellt, woraufhin die Einrichtung in der oben beschriebenen Weise weiterarbeitet. If necessary, air or other oxidizing gases can be fed into the combustion chamber, in order to operate the pump in the manner described above. After dia pump the combustion chamber Has gel-fed with liquid fuel, the mixture of fuel and oxidizing Gas ignited. After stable combustion has occurred, the turned off oxidizing gas, whereupon the device continues to operate in the manner described above.
