Bekanntlich wird brennbares Erdgas in der flüssigen Phase bei Atmosphärendruck und bei sehr niedrigen Temperaturen beispielsweise in der Größenordnung von -16O0C mit Hilfe von Spezialschiffen auf dem Seeweg transportiert. Bei der Ankunft des Spezialschiffe an einer Empfangsstelle muß das Gas vor der Verteilung an die Verbraucher, sowohl bei industriellen \erbrauchern als auch bei Privatverbrauchern, wieder verdampft werden.It is known that combustible natural gas is transported in the liquid phase at atmospheric pressure and at very low temperatures, for example in the order of magnitude of -16O 0 C, with the help of special ships by sea. When the special ship arrives at a receiving point, the gas has to be vaporized again before it is distributed to consumers, both for industrial users and private users.

Das verflüssigte Erdgase durchläuft zunächst den Austauscher 21, wo es die Ansaugluft des Luftkompressors 22 der Gas-= turbine kühlt.

Die Abgase des Turbinenteils 26 der Gasturbine und die Abgase des Dieselmotors 24 werden im Verdampfer 28 dazu benutzt, das die Entspannungsturbine 29 antreibende Strömungsmittel zu verdampfen.The exhaust gases from the turbine part 26 of the gas turbine and the exhaust gases from the diesel engine 24 are added in the evaporator 28 used to evaporate the expansion turbine 29 driving fluid.
Der Kreislauf der Entspannungsturbine 29 wird von dem in der Dampfphase befindlichen Strömungsmittel vom Verdampfer 28 zur Turbine 29 und zum Kondensator 31 durchlaufen, worauf es in der flüssigen Phase von der Umlaufpumpe 32 zum Erhitzer 33 und dann wieder zum Verdampfer 28 strömt.The circuit of the expansion turbine 29 is from the fluid in the vapor phase from Evaporator 28 to turbine 29 and to condenser 31 pass through, whereupon it is in the liquid phase of the Circulation pump 32 flows to the heater 33 and then back to the evaporator 28.
Fie oben bereits angegeben wurde, gelangt das verflüssigte Erdgas bei sehr niedrigen Temperaturen in der Größenordnung von ~16O°C in seinen Kreislauf. Durch seine Verdampfung kann die Ansaugluft der Wärmekraft·= maschinen, beispielsweise des Dieselmotors und der Gasturbine, bis auf eine niedrige Temperatur, beispielsweise in der Größenordnung von -10O0Cj, gekühlt werden; aus diesem Grund sind besondere Maßnahmen zu treffen, damit Kondenswasser eliminiert wird, das in feuchter Luft enthalten ist. Wenn bei der Ansaugluft der Wärme= kraftmaschinen von einer Temperatur in der Größenordnung von 1000C ausgegangen wird, und unter der Annahme der beabsichtigten Druckverhältnisse, kann die Temperatur der Ansaugluft möglicherweise auf vorteilhafte Werte abgesenkt werden; insbesondere im Falle eines Dieselmotors könnte der herkömmliche Kühler weggelassen werden, der zusammen mit einem Turbolader benutzt wird.As stated above, the liquefied natural gas enters its cycle at very low temperatures of the order of ~ 160 ° C. As a result of its evaporation, the intake air of the thermal power machines, for example the diesel engine and the gas turbine, can be cooled down to a low temperature, for example in the order of magnitude of -10O 0 Cj; For this reason, special measures must be taken to eliminate condensation that is contained in humid air. When the intake air at the heat = engine from a temperature of the order of 100 0 C starting, and assuming the intended pressure conditions, the temperature of the intake air may possibly be lowered to advantageous values; particularly in the case of a diesel engine, the conventional cooler that is used in conjunction with a turbocharger could be omitted.
Die Kompressorsarbeit der Ansaugluft ist kleiner, wenn diese Kompression bei niedrigen Temperaturen erfolgt, woraus sich eine entsprechende Reduzierung der Arbeit ergibt, die von dem Turbinenteil zu erbringen ist, die den Kompressorteil antreibt. InfolgedessenThe compressor work of the intake air is less when this compression is carried out at low temperatures takes place, resulting in a corresponding reduction in the work to be performed by the turbine part which drives the compressor part. Consequently

könnte auch zugunsten des Wirkungsgrades eine ausgedehntere Entspannung vorgesehen werden. Der Endgewinn wäre also eine Vergrößerung der spezifischen Leistung, ohne gleichzeitige Erhöhung der thermischen Beanspruchungen.a more extensive relaxation could also be provided for the benefit of the efficiency. So the bottom line would be an increase in the specific power without a simultaneous increase in the thermal loads.
Es sind hier Ausführungsbeispiele der Erfindung beschrieben worden, doch ist erkennbar, daß die Erfindung bei allen Anlagen angewendet werden kann, bei denen verflüssigtes Gas in Zusammenwirkung mit der Speisung von Wärmekraftmaschinen verdampft wird.Embodiments of the invention have been described herein, but it will be recognized that the invention applies to all of them Systems can be used in which liquefied gas interacts with the feed of heat engines is evaporated.
