KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei Dampfkesseln zur augenblicklichen Dampferzeugung (Schlangenrohrkesseln) ergeben sich bei plötzlicher Dampfentnahme bedeutende Druckunterschiede innerhalb des Kessels, welche daher rühren, daß durch jede Druckverminderung in dem den Dampfraum bildenden Teil des Schlangenrohres eine Nachverdampfung im mittleren, den Dampfentwicklungsraum bildenden Kesselten, hervorgerufen wird, während infolge der Trägheit der im Schlangenrohre befindlichen Wassersäule die ursprüngliche Spannung in dem den Wasserraum bildenden Kesselteil noch durch einige Zeit bestehen bleibt, wenn die Spannung an der Dampfentnahmestelle bereits wesentlich, unter Umständen bis auf die Hälfte und darunter gesunken ist. Wird nun ein derartiger Schlangenrohrkessel mittels einer Dampfspeisevorrichtung — beispielsweise einer Dampfpumpe, eines Dampfstrahlgeblä'ses, Pulsometer oder dergl. — gespeist, welche ihren Betriebsdampf der Hauptdampfleitung des Kessels entnimmt, so bewirkt dieser Druckunterschied, daß der Gang der Dampfspeisevorrichtung verlangsamt oder dieselbe möglicherweise zum Stillstande gebracht wird, und zwar zu einem Zeitpunkte, in welchem mit Rücksicht auf den gesteigerten Dampfverbrauch aus der Hauptleitung der ungestörte Gang der Dampfspeisevorrichtung unerläßlich ist.In the case of steam boilers for instantaneous steam generation (snake tube boilers) if there is a sudden withdrawal of steam, significant pressure differences within the boiler, which hence stir that by any pressure reduction in the part forming the vapor space of the coiled pipe there is a post-evaporation in the middle, which forms the vapor development space Kesselten, while due to the inertia of the coiled tubes located water column the original tension in the water space forming The boiler part remains in place for some time when the voltage is applied to the steam extraction point has already decreased significantly, possibly by half or below. It is now such a coiled tube boiler by means of a steam feed device - for example a steam pump, one Steam jet blower, pulsometer or the like - fed, which takes its operating steam from the main steam line of the boiler, so causes this pressure difference that the operation of the steam feeder slows down or the same possibly brought to a standstill at a point in time in which considering the increased steam consumption from the main line the undisturbed Gear of the steam feeder is essential.
Zweck der Erfindung ist, den Gang der Dampfspeisevorrichtung von der erwähnten Druckschwankung unabhängig zu machen.The purpose of the invention is to change the gear of the steam feeder from the mentioned To make pressure fluctuation independent.
Dies wird dadurch erreicht, daß von einer vor dem Dampfentwicklungsraum liegenden Stelle des Schlangenrohrkessels ein Rohr abgezweigt wird, welches durch den Heizraum des Kessels geführt ist, und an dessen Ende der Dampf zum Betriebe der Speisevorrichtung entnommen wird. Dieser Zweig bleibt von der Druckschwankung im Kessel unberührt.This is achieved in that one is located in front of the steam generation space In the place of the coiled tube boiler, a pipe is branched off, which goes through the boiler room of the boiler is performed, and at the end of the steam to operate the feed device is removed. This branch remains unaffected by the pressure fluctuation in the boiler.
Auf der Zeichnung ist ein Ausführungsbeispiel der beschriebenen Anordnung in Umrissen dargestellt.In the drawing, an embodiment of the arrangement described is outlined shown.
α ist der Wasservorratsbehälter, b die Speisevorrichtung, c der Schlangenrohrkessel, e die Heizungsanlage und /der Hauptmotor, welcher an den Dampfraum 1 des Kessels angeschlossen ist. > α is the water storage tank, b the feed device, c the coiled tube boiler, e the heating system and / the main engine, which is connected to the steam chamber 1 of the boiler. >
Von einer vor dem Dampfentwicklungsraume 2 des Schlangenrohrkessels gelegenen Punkte zweigt ein Rohr g ab, dessen Ende in die Dampfspeisevorrichtung b mündet. Der im Rohre g herrschende Druck ist dem im Wrasserrauine 3 des Schlangenrohrkessels immer gleich oder nahezu gleich, und es regelt sich die dem Kessel zugeführte Wassermenge selbsttätig entsprechend dem Dampfverbrauch der Speisevorrichtung, deren Gang auf irgend eine bekannte Art, z. B. durch Drosselung des Dampfeintrittes oder -Austrittes, Veränderung des Füllungsgrades oder Drosselung in der Druckwasseiieitung oder dergl. eingestellt werden kann. Die Regelung kann auch mittels eines in das Rohr g eingeschalteten Drosselorganes bewirkt werden. A tube g branches off from a point located in front of the steam generation space 2 of the coiled tube boiler, the end of which opens into the steam feed device b. The pressure prevailing g in the tubes is the r in the W asserrauine 3 of the coiled tube boiler always equal or nearly equal, and it regulates the power supplied to the boiler water flow automatically in accordance with the steam consumption of the feed device, whose passage in any known manner, for. B. by throttling the steam inlet or outlet, changing the degree of filling or throttling in the pressure water line or the like. Can be set. The regulation can also be effected by means of a throttle element connected into the pipe g.
