Abstract
A process is useful for obtaining a mixture of combustible gases and vapour in a rotary combustion chamber consisting of a shell, the outer circumference of which is surrounded by a water ring. The flame front and the combustible gases issuing from the central annular burner are in contact with the cooling water ring over its entire circumference. The vapour produced mixes with the combustible gases and causes a drop in temperature before the mixture reaches the turbine secured to the shell, resulting in rotation. Cooling is effected mainly by water, rather than excess air, resulting in a high degree of efficiency. A machine for implementing the process comprises a shell (15) which serves as a combustion chamber (2) secured to a compressor (1) and to a turbine (3). Air enters the compressor (1) through the hollow shaft and sucks vapour from the pre-chamber (11, 12). Fuel is admixed (8, 9) in the compressor. The flame touches the water ring of the combustion chamber which serves both as a cooling element and a vapour generator. The machine operates as a motor, and the mixture of combustible gases and vapour can be re-used subsequently as an energy carrier.

Beschreibungdescription
Die Erfindung betrifft ein Verfahren zur Herstellung eines Gemisches von Brenngasen und Dampf zum Betrieb einer Turbine sowie eine Maschine zur kontinuierlichen Erzeugung des Brenngase-/Dampfgemisches, welches mittels einer am Brennraum fixierten Turbine die ganze Maschine in Rotation versetzt und somit als Kraftmaschine dient.The invention relates to a method for producing a mixture of fuel gases and steam for operating a turbine and a machine for the continuous production of the fuel gas / steam mixture which rotates the entire machine by means of a turbine fixed to the combustion chamber and thus serves as an engine.
Bei den bekannten Gasturbinen liegt das Hauptübel darin, dass für den Verdichter ein zu grosser Arbeitsaufwand erforderlich ist, da für den Gasturbinenprozess eine hohe Luftüberschusszahl notwendig ist, um die Temperatur der Brenngase herabzusetzen, damit insbesondere das Material der Turbinenschaufeln nicht überhitzt wird. Dieses Problem der zu hohen Brenngastemperatur kann nur beschränkt durch Einsatz hitzebeständigen Materials gelöst werden, wodurch wegen der erreichbaren niedrigeren Luftüberschusszahl der Wirkungsgrad der Gasturbine verbessert werden kann. Dieses Problem der zu hohen Brenngastemperatur soll nun nicht über hitzebeständigeres und damit teures Material angegangen werden, sondern mit einem 'Verfahren, welches durch kontinuierliches Zuführen von Wasser während der Verbrennung ein gleichzeitiges Verdampfen von Wasser er¬ laubt, so dass das eingebrachte Wasser im flüssigen Zustand
vorwiegend der Materialkühlung und nachher als Dampf der Kühlung der Brenngase dient. Bei diesem Verfahrensablauf erfordert das Zuführen von Wasser einen geringen Arbeits¬ aufwand, wohingegen der entstandene Dampf zu einer Leistungssteigerung auf der Turbinenseite führt. Es wird also im Vergleich zu den üblichen Gasturbinen eine wesent¬ liche Verbesserung des Wirkungsgrades erreicht, indem nun anstelle von Luft das Wasser als Kühlmittel dient, welches nach Erfüllung des Kühlzweckes in Form von Dampf als Energieträger zusammen mit den Brenngasen der Turbine zugeleitet wird.The main problem with the known gas turbines is that too much work is required for the compressor, since a high excess of air is necessary for the gas turbine process in order to reduce the temperature of the fuel gases, so that in particular the material of the turbine blades is not overheated. This problem of the excessively high combustion gas temperature can only be solved to a limited extent by using heat-resistant material, as a result of which the efficiency of the gas turbine can be improved because of the lower excess air number that can be achieved. This problem of the excessively high combustion gas temperature is now not to be addressed by means of more heat-resistant and therefore expensive material, but rather by means of a process which, by continuously supplying water during the combustion, permits simultaneous evaporation of water, so that the water introduced is in the liquid state mainly used to cool the material and then as steam to cool the fuel gases. In this process sequence, the supply of water requires little work, whereas the steam produced leads to an increase in performance on the turbine side. In comparison to the usual gas turbines, a significant improvement in the efficiency is achieved in that instead of air, the water now serves as a coolant, which, after the cooling purpose has been fulfilled, is supplied in the form of steam as an energy carrier together with the fuel gases to the turbine.
Dies wird erfindungsgemäss gelöst, indem der Brennraum (2) zusammen mit dem Verdichter-/Turbinenteil (1,3) rotiert. In dem als Gehäuseschale ausgebildetem Brennraum (2) be- findet sich ein mitdrehender Wasserring, auf den die Flammen- und Brenngasefront zentrifugiert wird. Insbe¬ sondere durch die Kühlung des Materials mittels diesem Wasserring tritt kontinuierlich Dampf in die Brenngase, wodurch diese gekühlt, der Dampf aber überhitzt wird. Dieses Brenngase-/Dampfgemisch gelangt nun zur Turbine und setzt die ganze Maschine zusammen mit dem Brennraum in Rotation. Mit diesem Verfahren der Herstellung eines Gemisches zum Betrieb einer Turbine wird also erreicht, dass ein sehr hohes Wärmegefälle des Wassers zur Kühlung ausgenützt wird, wobei schliesslich der überhitzte Dampf zusätzlich als Energieträger dient. Die Verdampfung des Wassers aus dem Wasserring erfolgt problemlos, da sich das eine geringere Dichte aufweisende heissere Wasser nach innen, zur freien Oberfläche des Wasserringes bewegt, von wo der Dampf in den offenen Brennraum zur Vermischung mit den Brenngasen gelangt. Das eine niedrigere Tempera¬ tur aufweisende Wasser wird an die Innenwand der Gehäuse- schale (15) zentrifugiert und dadurch unter Druck gesetzt, was eine Erhöhung der Wassersiedetemperatur bewirkt. Bei diesem Verfahren eines offenen Kühlprozesses wird
dank der sehr hohen Kühlleistung des Wassers der Wasser¬ verbrauch im Rahmen bleiben.This is solved according to the invention by rotating the combustion chamber (2) together with the compressor / turbine part (1,3). In the combustion chamber (2), which is designed as a housing shell, there is a rotating water ring onto which the flame and fuel gas front is centrifuged. In particular, due to the cooling of the material by means of this water ring, steam continuously enters the fuel gases, which cools them, but the steam is overheated. This fuel gas / steam mixture now reaches the turbine and rotates the entire machine together with the combustion chamber. With this method of producing a mixture for operating a turbine, it is achieved that a very high heat gradient of the water is used for cooling, the superheated steam ultimately also serving as an energy source. The evaporation of the water from the water ring takes place without any problems, since the hotter water, which has a lower density, moves inwards to the free surface of the water ring, from where the steam reaches the open combustion chamber for mixing with the fuel gases. The water, which has a lower temperature, is centrifuged against the inner wall of the housing shell (15) and thereby pressurized, which causes an increase in the water boiling temperature. This process involves an open cooling process thanks to the very high cooling capacity of the water, water consumption remains within limits.
Eine zum Ausführen des in Anspruch 1 umschriebenen Ver¬ fahrens verwendbare Maschine zeigt die Figur 1 nach An-A machine which can be used to carry out the method described in claim 1 is shown in FIG.
5 spruch 2. Der Radialverdichter (1), die Turbine (3) und die Gehäuseschale (15) mit dem zum Verdichter und der Turbine offenen Brennraum (2) bilden als Rotationskörper eine Einheit, welche auf konventionelle Art gelagert werden kann (4). Der fixierte und zentrierte Leitschaufel-5 saying 2. The radial compressor (1), the turbine (3) and the housing shell (15) with the combustion chamber (2) open to the compressor and the turbine form a unit as a rotating body which can be stored in a conventional manner (4). The fixed and centered guide vane
10 apparat der Turbine (5) trennt zugleich den Brennraum (2) vom nach aussen offenen Wasserzuführ- und Wasserent¬ nahmeraum (7). Diese Trennung erfolgt durch eine dünne Scheibe am äusseren Umfang, welche in den rotierenden Wasserring hineintaucht. Mittels einem zum Beispiel bei10 apparatus of the turbine (5) at the same time separates the combustion chamber (2) from the water supply and water removal space (7), which is open to the outside. This separation takes place through a thin disc on the outer circumference, which dips into the rotating water ring. For example with a
15 Zentrifugen eingesetzten Schälrohres oder ähnlich dem bei einer Schälpumpe verwendeten Fangrohres (6) wird das Wasser zur Bildung des Wasserringes einer bestimmten Tiefe zugeführt und bei den sich im Brennraum zwangsläufig bil¬ denden Aenderungen der Wasserringtiefe wegen den Druck-15 centrifuges used peeling tube or similar to the collecting tube (6) used in a peeling pump, the water is fed to form the water ring to a certain depth and in the inevitably occurring changes in the combustion ring depth due to the pressure
20 und Drehzahlschwankungen auch wieder teilweise weggeführt, falls sich deswegen die Tiefe des Wasserringes im Brenn¬ raum (2) verringert. Diese hier vorgesehene mechanische Regelung des Wasserringes kann aber auch durch Wasserstands- meider erfolgen. Der Brennstoff wird mittels einer zentra-20 and speed fluctuations are also partially carried away again if the depth of the water ring in the combustion chamber (2) is therefore reduced. This mechanical regulation of the water ring provided here can also be carried out by water level avoiders. The fuel is
25 len, fixierten Leitung (8) in einen Hohlraum auf der Rück¬ seite des Radialverdichters (1) zugeführt und durch Oeff- nungen (9) in die verdichtete Luft hineinzentrifugiert. Das Luft-/Brennstoffgemisch wird nach Passieren von Schlit¬ zen (14) im äusseren Umfang des Verdichters oder einen25 len, fixed line (8) into a cavity on the back of the radial compressor (1) and centrifuged through openings (9) into the compressed air. The air / fuel mixture is after passing slits (14) in the outer circumference of the compressor or a
30 offenen Spalt in den Brennraum zentrifugiert, wo die Zün¬ dung auf konventionelle Art erfolgt. Die Flammenfront und die Brenngase treffen vorerst auf den kühlen Wasser¬ ring auf, was unter anderem eine reduzierte Bildung von Stickoxiden bewirkt. Um die Lagerseite (4) nicht einer
hohen Erwärmung auszusetzen und zusätzlich vermehrt Dampf zur Kühlung zu erhalten, wird durch die in den Wasser¬ ring tauchende und mitrotierende Schottscheibe (10) ein nach aussen abgeschlossener Vorraum (11) des Brennraumes geschaffen- Die an den Oeffnungen (12) vorbeiströmende, verdichtete Luft saugt den Dampf aus dem Vorraum ab und bewirkt zudem, dass dort ein geringerer Druck als im Brennraum entsteht, was zu einer Erhöhung der Verdampfung sowie einem tieferen Wasserring im Vorraum (11) als im Brennraum (2) und damit einer erhöhten Kühlleistung des Wassers führt. Das Brenngase-/Dampfgemisch gelangt zentri¬ petal über die Leitschaufeln in die Radialturbine (3) und setzt die Turbine zusammen mit dem Brennraum in Rota¬ tion. Zur Regelung der Drehzahl und damit auch des Druckes der verdichteten Luft kann die Leitschaufelvorrichtung (5) axial verschiebbar gestaltet werden, so dass ein Bypass entsteht. Dieser Bypass ist insbesondere von Be¬ deutung, wenn das Brenngase-/Dampfgemisch nach dem Ver¬ lassen der Turbine in eine andere Turbine geleitet, als Schub oder als Prozessmedium verwendet wird. Mit diesem Bypass ist es möglich, auch im Teillastbetrieb optimal zu fahren. Eine Steigerung des Druckes der verdichteten Luft wird erreicht, wenn dem Radialverdichter ein ein- oder mehrstufiger Axialverdichter vorgeschaltet wird, welcher in der Hohlwelle ebenfalls mit dem Gehäuse rotiert.30 open gap centrifuged into the combustion chamber, where the ignition takes place in a conventional manner. The flame front and the combustion gases initially strike the cool water ring, which among other things causes a reduced formation of nitrogen oxides. Not one around the bearing side (4) Exposing to high heating and additionally receiving more steam for cooling, an antechamber (11) of the combustion chamber which is closed to the outside is created by the partition disk (10) which rotates and rotates in the water ring. The compressed air flowing past the openings (12) sucks the steam out of the anteroom and also causes a lower pressure there than in the combustion chamber, which leads to an increase in evaporation and a deeper water ring in the anteroom (11) than in the combustion chamber (2) and thus an increased cooling capacity of the water . The fuel gas / steam mixture passes centrifugally through the guide vanes into the radial turbine (3) and rotates the turbine together with the combustion chamber. To regulate the speed and thus also the pressure of the compressed air, the guide vane device (5) can be made axially displaceable, so that a bypass is created. This bypass is particularly important if the fuel gas / steam mixture is passed into another turbine after leaving the turbine, or is used as a thrust or as a process medium. With this bypass it is possible to drive optimally even in partial load operation. An increase in the pressure of the compressed air is achieved if the radial compressor is preceded by a single or multi-stage axial compressor which also rotates in the hollow shaft with the housing.
Diese Turbine im rotierenden Brennraum ist nun sowohl hinsichtlich der Herstellungskosten, der Betriebssicher¬ heit und der Wirtschaftlichkeit günstig ausgelegt. Auch sind für den Brennraum und den Turbinenteil keine besonders hohen Anforderungen bezüglich der Hitzebeständigkeit des Materials erforderlich. Das gleiche gilt bezüglich der Qualität des verwendeten Brennstoffes, wobei die Verbrennung im gekühlten Brennraum zu einer Minimierung von Schadstoffen führt.
Die Ansprüche 3 - 7 sind abhängig vom unabhängigen Patent¬ anspruch 2, wobei die Unteransprüche 3 bis 6 verschiedene bekannte Anordnungen der Turbine betreffen, also die abgegebene Leistung der Gas-/Dampfturbine im rotierenden Brennraum mit Wasserkühlung.This turbine in the rotating combustion chamber is now designed to be inexpensive both in terms of production costs, operational reliability and economy. Also, the combustion chamber and the turbine part do not have to meet particularly high requirements with regard to the heat resistance of the material. The same applies to the quality of the fuel used, with combustion in the cooled combustion chamber minimizing pollutants. Claims 3-7 are dependent on independent patent claim 2, subclaims 3 to 6 relate to various known arrangements of the turbine, that is to say the output of the gas / steam turbine in the rotating combustion chamber with water cooling.
Der Anspruch 7 bezieht sich auf die Verdichterseite, wobei zur Druckerhöhung in den Brennraum nicht eine vermehrte Arbeitsleistung durch den Verdichter abverlangt wird, sondern durch Einspritzung von Wasser durch die zentrale und fixierte Leitung (13) und anschliessendem zentrifu¬ galem Ausschleudern in den Brennraum nach Passieren der Oeffnungen (9) die Zerstäubung des Wassers zu Hilfe genom¬ men wird. Die dabei entstehende Tröpfchenwand wirkt ähnlich einer Flüssigkeitswand, wodurch einem höheren Druck im Brennraum entgegengewirkt werden kann. Sollte dabei mehr Wasser in die Gehäuseschale gelangen als verdampft wird, erfolgt zwangsläufig eine Rückführung des überschüssigen Wassers mittels dem Zuführ-/Fangrohr (6).
The claim 7 relates to the compressor side, whereby to increase the pressure in the combustion chamber not an increased amount of work is required by the compressor, but rather by injecting water through the central and fixed line (13) and subsequent centrifugal ejection into the combustion chamber after passing the orifices (9) help to atomize the water. The resulting droplet wall acts like a liquid wall, which means that a higher pressure in the combustion chamber can be counteracted. If more water gets into the housing shell than is evaporated, the excess water is inevitably returned by means of the feed / collecting pipe (6).
