Description
Verfahren zum Betrieb von Saugzuganlagen für Lokomotiv-Feuerungen. Es ist bekannt, den Abdampf von Dampflokomotiven mittels eines Blasrohres oder auch eines von einer Dampfturbine angetriebenen Ventilators zur künstlichen Zugerzeugung unmittelbar zu verwenden. Der gesamte Abdampf strömt dabei ins Freie.Procedure for operating induced draft systems for locomotive furnaces. It is known that the exhaust steam from steam locomotives by means of a blowpipe or a fan driven by a steam turbine for artificial draft generation to use immediately. The entire exhaust steam flows into the open air.
Eine derartige Einrichtung erfordert die ständige Verwendung von Frischwasser zur Speisung des Kessels. Dies gibt entweder Anlaß zu Verunreinig urigen oder Ablagerungen im. Kessel und bedingt daher eine häufige Reinigung desselben oder erfordert besondere Maßnahmen zur Reinigung des gesamten Speisewassers. .Such a device requires the constant use of fresh water to feed the boiler. This gives rise either to dirt or deposits in the. Boiler and therefore requires frequent cleaning of the same or requires special Measures to clean the entire feed water. .
Demgegenüber bringt die Erfindung eine wesentliche Verbesserung. Die Erfindung besteht darin, daß der Abdampf nicht, wie bisher, ummittelbar zur Zugerzeugung verwendet, sondern durch einen Wärmeaustauscher hindurchgeleitet wird, in welchem Wasser verdampft wird, wobei der entstehende Dampf zur Erzeugung des zur Feueranfachung benötigten. Zuges dient. Der Abdampf aus der Hauptkraftmaschine, die sowohl eine Turbine als auch eine Kolbenmaschine sein kann, wird niedergeschlagen und dem Kessel als Speisewasser wieder zugeführt; hierdurch gelangt stets reines Wasser (Konden lat) in den Kessel. Man braucht lediglich nur wenig Frischwasser zuzusetzen entsprechend den geringen durch Undichtheiten entstandenen Dampfverlusten. Dies ergibt eine wesentlich bessere Ausnutzung der Lokomotive, weil vor allem .die großen Betriebspausen zum Reinigen des Kessels in Fortfall kommen und die Lebensdauer des Kessels hierdurch erhöht wird.In contrast, the invention brings about a substantial improvement. the Invention consists in the fact that the exhaust steam is not, as before, directly used to generate draft used, but passed through a heat exchanger in which Water is evaporated, whereby the resulting steam is used to generate the to ignite the fire required. Train serves. The exhaust steam from the main engine, which is both a Turbine as well as a piston engine can be knocked down and the boiler supplied again as feed water; this means that pure water (condensation lat) into the boiler. You only need to add a little fresh water accordingly the low steam losses caused by leaks. This gives an essential better utilization of the locomotive, especially because of the major breaks in operation Cleaning of the boiler is a thing of the past and the lifespan of the boiler as a result is increased.
Da der Wärmeübergang im Wärmeaustausch:er ein sehr guter ist - die Wärmeübergangszahl ist nämlich sowohl für kondensierenden als auch für entstehenden Dampf sehr hoch -, so kommt man mit geringen Wärmedurchgangsflächen aus.Since the heat transfer in heat exchange: it is a very good one - the Heat transfer coefficient is namely for both condensing and emerging Very high steam - that's how you get by with small heat transfer surfaces.
Auf der Zeichnung ist schematisch eine Anlage zur Ausführung des Verfahrens gemäß der $rfmdung dargestellt.The drawing shows a system for carrying out the method shown according to the figure.
Der Abdampf der Antriebsmaschinea wird mittels eines Rohres durch ,einen Wärmneaüstausch.er b hindurchgeleitet. Das zur Dampferzeugung dienende Wasser wird dem Wärmeaustauscher durch die Kühlwasserpumpe c zugeführt. Der durch die Abdampfwärme der Antriebsmaschine erzeugte Dampf strömt durch die Düse d des Blasrohres und saugt die Rauchgase durch den Kamin e ab. Der Dampf kann auch zum Betrieb einer Hilfsturbine verwendet werden, welche mit einem Ventilator gekuppelt ist und dadurch den Zug erzeugt. Der niedergeschlagene Abdampf aus der Hauptmaschine wird durch die Kesselspeisepumpe f abgesaugt und gelangt wieder in den Kessel.The exhaust steam from the drive machine is passed through a pipe , a Wärmneaüstausch.er b passed through. The water used to generate steam is fed to the heat exchanger by the cooling water pump c. The one through the exhaust heat Steam generated by the prime mover flows through nozzle d of the blowpipe and sucks the flue gases through the chimney e. The steam can also be used to operate an auxiliary turbine which is coupled to a fan and thereby the train generated. The precipitated exhaust steam from the main engine is fed through the boiler feed pump f is extracted and returned to the boiler.
