Es ist ein bekanntes Verfahren, chemische Reaktionen von Stoffen, die bei normalen Temperaturen träge reagieren, bei hohen Temperaturen vor sich gehen zu lassen und dann schnell zu kühlen, um die nun entstandenen Substanzen schnell in einen Temperaturbereich zu bringen, in dem keine Rückbildung auftritt.It is a well-known process of chemical reactions of substances that occur during normal Temperatures react sluggishly at high To let temperatures go and then to cool quickly to the ones that have now arisen To bring substances quickly into a temperature range in which no regression occurs.
Solche Verbindungen z. B., die bei der BiI-dung Wärme absorbieren (endothcrmische), zerfallen wieder bei der späteren Abkühlung, falls die Abkühlungsperioden in den Temperaturbezirken, in denen noch relativ hohe Reaktionsgeschwindigkeiten auftreten, nicht schnell genug, im Vergleich zu den Reaktionsgeschwindigkeiten, durchlaufen werden.Such compounds e.g. B. that in education Absorb heat (endothermic), disintegrate again during the later cooling, if the cooling periods in the temperature areas, in which relatively high reaction rates still occur, not fast enough compared to the reaction rates.
Außer der Erzeugung einer entsprechendExcept for generating a corresponding
hohen Temperatur ist daher eine praktische Schwierigkeit bei solchen Reaktionen die schnelle Erniedrigung der Temperatur, das ist . die schnelle Abführung der Energie.high temperature is therefore a practical difficulty in such reactions rapid lowering of temperature, that is. the rapid dissipation of energy.
Bei solchen chemischen Stoffen, die in dem Temperaturbezirk, in dem die Reaktion vor sich geht, gasförmig sind, läßt sich die Energie nun sehr schnell abführen und dadurch die Temperatur erniedrigen, daß man das erhitzte und komprimierte. Gas aus einer Düse ' ausströmen läßt, die gegebenenfalls noch künstlich gekühlt wird, falls die natürliche Ableitung nicht genügt.For such chemical substances, in the temperature zone in which the reaction takes place are gaseous, the energy can now be dissipated very quickly and thereby the Lower the temperature by heating and compressing it. Blow gas out of a nozzle leaves, which is possibly still artificially cooled, if the natural discharge not enough.
Im Gegensatze zu einfachen Ausflußöffnungen haben die Düsen keine plötzlichen, sondern nur allmähliche Quersclmittsänderungen, und hierdurch lassen sich einesteils Stoßverluste, d. h. die Rückverwandlung von kinetischer Energie in Wärme sehr bedeutend be- · schränken, und es ist andererseits möglich, sehr bedeutende Wärmemengen in kinetische Energie umzusetzen. Diese beiden Eigenschaften einer Düse mit ihren' speziell bemessenen, stetig geänderten Querschnitten sind für den vorgesetzten Zweck wichtig, denn es ist notwendig, 1. den niedrigen Temperaturzustand eine gewisse Zeit aufrecht zu erhalten und 2. in der kurzen Durchflußzeit große Wärmemengen in · kinetische Energie umzusetzen. In contrast to simple orifices, the nozzles do not have sudden, but rather only gradual cross-median changes, and as a result, on the one hand, shock losses, i. H. the reverse transformation of kinetic Limit energy in heat very significantly, and on the other hand it is possible convert very significant amounts of heat into kinetic energy. These two properties a nozzle with their 'specially dimensioned, constantly changing cross-sections important for the intended purpose, because it is necessary to 1. the low temperature condition to maintain a certain time and 2. large in the short flow time To convert amounts of heat into kinetic energy.
Die Zeichnung stellt eine solche Anordnung als Beispiel dar. ■The drawing shows such an arrangement as an example. ■
In den Raum β trete z.B. Wasserdampf unter Druck und mit hoher Temperatur ein; diese Temperatur werde durch den Lichtbogen I noch bedeutend gesteigert, so daß der Wasserdampf dissoziiert. Im Räume r sei ein tieferer Druck, so daß das Gasgemisch in der eigentlichen Düse b eine hohe Geschwindigkeit erlangt und seine Temperatur in der kurzen Zeit, in der das Gas von A nach B gelangt, bedeutend reduziert wird. Diese Temperaturreduktion muß so groß sein, daß eine wesentliche Rückbildung (im Falle unseres Beispiels eine Verbrennung zu Wasser) nicht mehr stattfinden kann. Auf der Strecke r muß dann eine weitere Abkühlung erfolgen, so daß auch, wenn das Gas z. B. in dem Sammelrohrc d seine Geschwindigkeit wiederFor example, water vapor under pressure and at high temperature would enter the space β; this temperature will be increased significantly by the arc I , so that the water vapor will dissociate. Let the pressure in space r be lower, so that the gas mixture in the actual nozzle b attains a high speed and its temperature is significantly reduced in the short time in which the gas passes from A to B. This temperature reduction must be so great that substantial regression (in the case of our example, combustion to water) can no longer take place. On the route r , a further cooling must then take place, so that even if the gas z. B. in the collecting pipe c d its speed again
