Description

Einrichtung zur Abscheidung der Feuchtigkeit aus dem Arbeitsdampf von Dampfturbinen Es ist bekannt, daß der mit fortschreitender Entspannung zunehmende Feuchtigkeitsgehalt des Arbeitsdampfes einer Dampfturbine Anlaß zu einer Zerstörung des Schaufelbanstofies gibt. Um die Erosion zu verringern, kann man entweder den Dajnpf durch Zufuhr von Wärme trocknen oder auf mechanischem Wege die Flüssigkeitsteilchen abscheiden. Die Trocknung des Dampfes durch 'Wärmezufuhr erfordert ein verhältnismäßig teures und langes Leitungsnetz, das infolge seines Strömungswiderstandes Anlaß-zu einem nicht unerheblichen Verlust am Druckgefälle gibt. Die mechanische Abscheidung des Wassergehältes aus dem Dampf ist in dieser Beziehung einfacher, läßt sich aber nur unter ganz bestimmten Voraussetzungen durchführen.Device for separating the moisture from the working steam of steam turbines It is known that the increasing relaxation increases Moisture content of the working steam of a steam turbine gives rise to destruction of the Schaufelbanstofies there. To reduce erosion, you can either use the Dry the steam by adding heat or by mechanical means to dry the liquid particles deposit. The drying of the steam by 'supply of heat requires a relatively expensive and long pipeline network, which, due to its flow resistance, is start-up there is a not inconsiderable loss of the pressure gradient. The mechanical separation the water content from the steam is simpler in this respect, but it can be only to be carried out under very specific conditions.

Gemäß der Erfindung wird von einer bekannten physikalischen Erscheinung Gebrauch gemacht, nämlich von den Vorgängen im elektrischen Feld, die man im Elektrofilter. ausnutzt, um Ascheteilchen aus den Rauchgasen einer Feuerung zu entfernen oder Schwebeteilchen enthaltende Abgase, z. B. in der Hüttenindustrie, zu reinigen. Dieses Verfahren wird gemäß der Erfindung auf die Entfernung der Dampffeuchtigkeit aus dem Arbeitsdampf von Dampfturbinen angewendet, und die Erfindung besteht darin, daß der Dampf in einer Elektrofilteranlage getrocknet wird. Dies bietet gegenüber den bisherigen Vorschlägen insofern wertvolle Vorteile, als die Einrichtung ohne großen baulichen Aufwand unmittelbar neben der Maschine aufgestellt werden kann, und daß an den Verbindungsleitungen nur die Kabel erforderlich sind, die zur Zuleitung des hochgespannten Stromes dienen.According to the invention it is of a known physical appearance Made use, namely of the processes in the electric field, which one in the electrostatic precipitator. exploited to remove ash particles from the flue gases of a furnace or suspended particles containing exhaust gases, e.g. B. in the iron and steel industry to clean. This method is according to the invention on the removal of steam moisture from the working steam applied by steam turbines, and the invention is that the steam in an electrostatic precipitator is dried. This offers over the previous Suggestions insofar valuable advantages as the facility without major structural engineering Effort can be set up directly next to the machine, and that on the connecting lines only the cables that are used to feed the high-voltage current are required.

Die Praxis hat gezeigt, daß es möglich ist, mit dem Verfahren auch kleine Schwebeteilchen aus Gasen oder Dämpfen abzuscheiden, so daß man mit dem neuen Verfahren praktisch trocken gesättigten Dampf erhalten kann. Sollte es sich aus Gründen der Verbilligung nicht als zweckmäßig erweisen, die gesamte Dampftrocknung in einer Elektrofilteranlage vorzunehmen, so kann man in der Weise vorgehen, daß man mit dieser nur die größten Schwebeteilchen abscheidet und die feineren im Dampf läßt oder durch Wärmezufuhr verdampft. Da die in diesem Fall aufzubringende Verdampfungswärme klein ist, so läßt sich eine gute Trocknung und gegebenenfalls eine anschließende Überhitzung mit kleinen Heizflächen und genügendem kleinen Heizmittelaufwand herbeiführen.Practice has shown that it is possible with the procedure too separate small suspended particles from gases or vapors, so that you can deal with the new Process can obtain practically dry saturated steam. It should work out For reasons of cheapness do not prove expedient, the entire steam drying to undertake in an electrostatic precipitator system, one can proceed in such a way that this only separates the largest suspended particles and the finer ones in the steam leaves or evaporates by supplying heat. Because the evaporation heat to be applied in this case is small, a good drying and, if necessary, a subsequent drying Bring overheating with small heating surfaces and a small amount of heating medium.
