Description

Es ist bekannt, Dampfturbinen bei Schleppbetrieb :durch Einführen vorn Dampf zu, kühlen. Es ist dabei auch bekannt, den Kühlidamp.f aiuis .dem Koindens,ator zu entnehmen .und oberhalih ideir zu kühlenden Schaufeln in die Turbine eiinzuf "uhTen, wobei der Dampf durdh die Sa"ugwirkwng der Tu,rbiinien!sdhawfeln umgewälzt wird.It is known to tow steam turbines: by introducing them in front of steam, cool. It is also known to use the Kühlidamp.f aiuis .dem Koindens, ator to be taken and fed into the turbine above the blades to be cooled "uhTen, the steam being circulated through the suction effect of the door lines! sdhawfeln will.

Diieise Umwälzung durch die, Schaufeln selbst hat den Nachteil, daß se bei manchen Beschaufelungen nicht genügt.This circulation through the blades themselves has the disadvantage that se is not sufficient with some blading.

Diesen Mangel soll die, Erfindung beheben.The invention is intended to remedy this deficiency.

Die, Erfindung betrifft also: :eine Einrichtung, um eine Dampfturbine im Sdhleppbetriieb mnttels Dampf aufs dem Kondensator der Turbine Sie bestecht in einier odier mehreren Dampfstrahlpumpien, .die den Dampf -aus dem KondienisatioT saugen rund oib,er'halb. der ziu küihlenden Saufen in die Turbine einführen.The invention thus relates to: a device for a steam turbine In the Sdhleppbetrieb by means of steam on the condenser of the turbine you are bribed in one or more steam jet pumps, which take the steam out of the condensing unit suck around oib, er'halb. of the cool drinks in the turbine.

Dampfstirahlp@umpen sind einfach im Aufbau und im Betrieb und brauchen wenig Raum. Da die nötige Kü hldamp@fmenge tim Versgleich zur normalen Betri@ebisdampfmenge klein .ist, also der Kübdidampfdruck am Eintritt in .die Twrblin@e nur wenig höher als edier Kondensatordruck zu sein, braucht, so kann bzw. können die Strahlpumpe(n) klein sein. Als Treibmittel kann Frischdampf odeir Dampf beliebigen Drucks oder beliebiger Temperiatur dienen. Falldis mehrere Kondeneatoren vorbanden send, bzaucht der Kühldampf nur ans einem von ihnen abgesaugt zu werden.Dampfstirahlp @ umpen are easy to assemble and operate and need little space. Since the necessary amount of cooling steam is compared to the normal amount of steam is small, i.e. the container vapor pressure at the entrance to the Twrblin @ e is only slightly higher than it needs to be condenser pressure, so can or can the jet pump (s) be small. Live steam or steam of any pressure or pressure can be used as the propellant serve any temperature. Falldis several condensers in front of the band send, or blown the cooling steam can only be extracted from one of them.

Der Gegenstand edier Erfindung ist in der Zeichnung in: einem Amfüihrun@gsbeiispiel verianisichauliicht. hierin bezeichnet i dien I-I#achdrwckteil, 2 den zweifutigen Nie@derdruckteil, 3 dien Generator und 4 zwei Kondensatoiren. Der Kühldampf für den Ho ch:diruckteil i tritt durch Idas Ventil 5 und die Stopfbüchse 6 ein. In vielen Fäl!lien wird: .der Sperrdampf der Stopfbüdhsie 6 allein zur Kühlung des Turbin,enhochdruoktei!les i genügen. Am Ende dies Hochdruckteiles i strömt der Dampf .durch die Überströmleitung i i zumüederdrwcleteidi 2. Dort wird er mit dem :ans einem der Kondensatoren q. durch den Dampfstrahlsauger 7 abgesaugten, bereits gekühlten. Dampf, der durch die Leitung 8 zu der Überströmdeitunvg ii zuggeführt wimd, gemaischt. Durch die Miisöhunvg sinkt die Temperatur Beis Dumpfes in der Überströmleitung i i iso weit ab, z. B. auf 40 biss 5o° C, idaß er :d'umch diie Ventilationsaxb@eit dies Niederdruckteiles nur auf die zulässige Temperatur vorn etwa 9o° C erwärmt wird. Der Treibdampf wird' durch die Leitung 9 zwgeiühTt und duirch das Ventil io geregelt.The subject of each invention is shown in the drawing in: an example of an example verianisichicht. Here i denotes the I-I # achprwckteil, 2 the double-digit Never the pressure part, 3 serve as a generator and 4 as two condensers. The cooling steam for the high: diruck part i enters through Ida's valve 5 and the stuffing box 6. In many Cases will be: .the sealing steam of the stuffing chamber 6 only for cooling the turbine, enhochdruoctei! Les i suffice. At the end of this high-pressure part i, the steam flows through the overflow line i i zumüederdrwcleteidi 2. There it is with the: ans one of the capacitors q. sucked off by the steam jet cleaner 7, already cooled. Steam coming through the Line 8 to the Überströmdeitunvg ii fed wimd, mashed. Through the Miisöhunvg If the temperature in the overflow line i i iso drops far, z. B. to 40 to 50 ° C, that he: d'umch die Ventilationsaxb @ t this low-pressure part is only heated to the permissible temperature in front of about 9o ° C. The motive steam is' forced through line 9 and controlled by valve io.
