"Gasentnahmesonde für sehr heiße Gase""Gas sampling probe for very hot gases"
Die Erfindung betrifft eine Gasentnahmesonde für sehr heiße Gase, bei der die Kühlung dadurch erfolgt, daß eine im Raum zwischen dem Entnahmerohr und einem Mantelrohr unter Überdruck stehende Wassermenge kontinuierlich in einem geschlossenen Kreislauf eine Verdampfung erfährt mit nachfolgender Kondensation des Dampfes in einem mit getrenntem Kühlmittel betriebenen Kondensatorteil, von wo aus das Kondensat in den Verdampfungsraum zurückfließt.The invention relates to a gas sampling probe for very hot Gases that are cooled by having one in the room Between the extraction pipe and a jacket pipe, the amount of water under positive pressure continuously in a closed Circuit undergoes evaporation with subsequent condensation of the vapor in a separate coolant operated condenser section, from where the condensate flows back into the evaporation chamber.
Bei Ofentemperaturen über 15000C treten bei dieser Art von Gaeentnahmesonden erhebliche Materialspannungen im Rohrsystem auf, da zwischen Außenmantel und Innenrohr große Temperaturunterschiede vorhanden sind und ee kann vorkommen, daß die Sonde durch Reißen der Schweißnähte zerstört wird*At furnace temperatures above 1500 0 C, considerable material stresses occur in the pipe system with this type of gas sampling probe, since there are large temperature differences between the outer jacket and the inner pipe and it can happen that the probe is destroyed by tearing the welds *

Die Erfindung zeigt einen Weg, wie dieeer Gefahr begegnet werden kann. Erfindungsgemäß besteht das Entnahmerohr aus zwei Rohrteilen, die durch ein elastisches Glied miteinander verbunden sind. Als elastisches Glied kann z.B. ein Wellrohr benutzt werden.The invention shows one way in which this danger is met can be. According to the invention, the extraction tube consists of two pipe parts connected to each other by an elastic member are connected. A corrugated pipe, for example, can be used as the elastic member.
Ein Ausführungsbeispiel der neuen verbesserten Gasentnahmesonde wird an Hand der Zeichnung näher erläutert. Hierbei zeigt Pig. 1 eine Seitenansicht einer in einen Ofenraum eingebauten Gasentnahmesonde mit elastischem Ausgleichglied und Fig. 2 im Detail eine Möglichkeit der Einfügung des' elastischen Ausgleichsgliedes der Fig. 1.An embodiment of the new improved gas sampling probe is explained in more detail with reference to the drawing. Pig. 1 is a side view of a furnace chamber built-in gas sampling probe with elastic compensating element and FIG. 2 shows in detail a possibility of inserting the elastic compensating member of FIG. 1.
In der Spitze der schräg nach unten in einen Ofenraum eingebauten Gasentnahmesomde verdampft im Raum zwischen dem Entnahmerohr 1 und -einem, äußeren Mantelrohr 2 eingefülltes Wasser 3* Der Wasserdampf gelangt über Rohrleitungen 4, 5 außerhalb des Ofens in eine Kühlvorrichtung 6, wo er kondensiert. Das Kondensat fließt durch Falleitungeisi 7, 8 zurück zum Wasservorrat in der Sondenspitze. Zur Kondensation des Wasserdampfes in der Kühlvorrichtung dient ein kühlwassergespeistes Rohrsystem 9-·In the top of the built-in obliquely downward in an oven chamber Gas sampling probe evaporates in the space between the Sampling tube 1 and an outer jacket tube 2 filled Water 3 * The water vapor arrives via pipes 4, 5 outside the furnace in a cooling device 6, where it condenses. The condensate flows back through Fallleitungeisi 7, 8 to the water supply in the probe tip. A cooling water-fed is used to condense the water vapor in the cooling device Pipe system 9-

ist ein Stück Wellrohr 11 eingesetzt. Es macht die Spannungen unwirksam, die sich sonst durch die unterschiedliche Längsausdehnung des Entnahme- und des Außemrohres als Folge der Temperaturdifferenz zwischen beiden ausbilden und verhindert somit ein Reißen der Schweißnähte 12 an der Sondenspitze.a piece of corrugated pipe 11 is used. It makes the tension ineffective, which is otherwise due to the different longitudinal expansion of the extraction and the outer tube as a result of Form a temperature difference between the two and thus prevent tearing of the weld seams 12 at the probe tip.
Gemäß Fig. 2 greifen an der Verbindungsstelle mit dem Wellrohr die Enden der beiden Rohrteile 13» 14 des Gasentnahmerohres innerhalb des Wellrohres teilweise ineinander. Die ä ineinandergreifenden Enden bewahren das Wellrohr vor radialer Deformation durch den im Raum zwischen dem Mantelrohr und dem Gasentnahmerohr herrschenden Druck.According to FIG. 2, the ends of the two pipe parts 13 »14 of the gas sampling pipe grip at the connection point with the corrugated pipe partially into one another within the corrugated pipe. The Ä Interlocking ends protect the corrugated pipe from radial deformation caused by the space between the jacket pipe and the pressure prevailing in the gas sampling pipe.
