Description
Vorrichtung zur Verhinderung von Eisbildung an Preßluftturbinen. Zur Vermeidung von Eisbildung an -Preßluftturbinen wird gemäß vorliegender Erfindung den Turbinenschaufeln von außen Wärme zugeführt. Das kann einmal geschehen durch die an sich bekannte Verwendung hohler Schaufeln, die von warmer Luft durchströmt werden.Device for preventing ice formation on compressed air turbines. To the Avoidance of ice formation on compressed air turbines is in accordance with the present invention the turbine blades are supplied with heat from the outside. That can happen once through the use of hollow blades, known per se, through which warm air flows will.
Abb. r zeigt die Anwendung der Erfindung auf Achsialräder mit radial stehenden Schaufeln. Die Laufradscheibe L ist mit Bohrungen B versehen oder doppelwandig ausgeführt. Die warme Luft kann in geeigneter Weise durch die hohle Welle eingeführt werden und strömt durch die hohlen Schaufeln, an die sie ihre Wärme abgibt. Abb. 2 veranschaulicht die Anwendung der Erfindung auf Radialräder mit achsial gerichteten Schaufeln.Fig. R shows the application of the invention to axial gears with radial standing shovels. The impeller disc L has holes B provided or double-walled. The warm air can suitably pass through the hollow shaft are introduced and flows through the hollow blades to which it is attached gives off their heat. Figure 2 illustrates the application of the invention to radial gears with axially directed blades.
Eine andere Möglichkeit zur Beheizung der Schaufeln besteht gemäß der Erfindung darin, daß gemäß Abb.3 in die hohle Schaufel S eine Heizpatrone HP eingebaut wird, die mittels elektrischen Stromes betrieben wird. Die Erzeugung des Stromes geschieht durch einen von der Turbine selbst betriebenen, zweckmäßig am Laufrad angebauten Generator G, die 'Stromzuführung über das Kabel K und die Bürste B auf den Schleifring SR, an welchen die Heizpatronen einpolig angeschlossen sind. Die Rückführung des Stromes geschieht zweckmäßig durch die Masse des Laufrades selbst.Another possibility for heating the blades is according to the invention is that according to Fig.3 in the hollow blade S a heating cartridge HP installed, which is operated by means of electrical current. The generation of the Electricity is carried out by a turbine operated by the turbine itself, expediently on Generator G attached to the impeller, the power supply via the cable K and the brush B on the slip ring SR, to which the heating cartridges are connected with one pole. The current is expediently fed back through the mass of the impeller itself.
Die Schwierigkeit der Stromzuführung und der Unterbringung der Heizpatronen in den Schaufeln will eine weitere Ausführung der Erfindung durch Anwendung von Wirbelströmen umgehen. Zur Erzeugung derselben werden (s. Abb. 4) am Umfange des Turbinenlaufrades L ein oder mehrere permanente Magnete M angeordnet, und zwar so, daß der Schaufelkranz zwischen den Polen des Magneten umläuft. Durch das magnetische Feld werden in dem Schaufelkranz Induktioneströme erzeugt, die, da sie kurzgeschlossen sind, die Erwärmung des Schaufelkranzes bewirken. Die Wirkung kann gemäß Abb.5 dadurch elhöht werden, daß an Stelle eines permanenten Magneten ein Elektromagnet verwendet wird, der von einem am -Laufrad angebauten Generator G gespeist wird.The difficulty of the power supply and the placement of the heating cartridges in the blades, another embodiment of the invention is desired by using Avoid eddy currents. To generate the same (see Fig. 4) on the circumference of the Turbine impeller L one or more permanent magnets M arranged, namely so, that the blade ring rotates between the poles of the magnet. Through the magnetic Field induction currents are generated in the blade ring, which because they are short-circuited cause the blade ring to heat up. The effect can be shown in Fig It can be increased that an electromagnet is used instead of a permanent magnet which is fed by a generator G attached to the impeller.
