"Verfahren zur Abkühlung von unter hohem Druck und hoher Temperatur stehenden Prozeßgasen ""Process for cooling process gases under high pressure and high temperature"
Die Erfindung betrifft ein Verfahren zur Abkühlung von unter hohem Druck und hoher Temperatur stehenden Prozeßgasen, wobei die abgeführte Wärme zur Hochdruckdampferzeugung nach dem Naturumlaufprinzip verwendet wird und der Abkühlungsprozeß über ein in einem stehenden Behälter hängend angeordnetes U-Rohr-System erfolgt.The invention relates to a method for cooling process gases under high pressure and high temperature, whereby the dissipated heat is used to generate high pressure steam according to the natural circulation principle and the cooling process takes place via a U-tube system suspended in a standing container.
Die Abkühlung von unter hohem Druck und hoher Temperatur stehenden Prozeßgasen ist für den Warmeaustauschprozeß insofern problematisch, als extrem hohe Wärmestromdichten zu erwarten sind. Es ist daher bei Anwendung des Naturumlaufprinzips erforderlich, auf den Wärmeaustauschprozeß Einfluß zu nehmen, damit insbesondere auch während der Anfahrphase und bei Druckschwankungen auf der Kühlmittelseite eindeutige Naturumlaufverhältnisse geschaffen werden. The cooling of process gases under high pressure and high temperature is essential for the heat exchange process problematic insofar as extremely high heat flux densities are to be expected. It is therefore when applying the natural circulation principle required to influence the heat exchange process, so especially during the Start-up phase and in the event of pressure fluctuations on the coolant side, clear natural circulation conditions are created.
909831 /CU25909831 / CU25
Die vorliegende Erfindung hat sich daher die Aufgabe gestellt, den Wärmeaustajschprozeß bei der Abkühlung von unter hohem Druck und hoher Temperatur stehenden Prozeßgasen kühlmittelseitig bei Einsatz eines U-Rohr-Bündels als Wärmeaustauscherelement so zu beeinflussen, daß während des gesamten Abkühlungsprozesses, unabhängig vom Anfahrvorgang und von Druckschwankungen auf der Kühl— mittelseite, das verwendete Naturumlaufprinzip stabil bleibt.The present invention has therefore set itself the task of the heat exchange process during the cooling of Process gases under high pressure and temperature on the coolant side when using a U-tube bundle as a heat exchanger element to influence that during of the entire cooling process, regardless of the start-up process and pressure fluctuations on the cooling middle side, the natural circulation principle used remains stable.
Zur Lösung dieser Aufgabe wird nach der Erfindung vorgeschlagen, daß das beim Abkühlungsprozeß in Hochdruckdampf überzuführende Kühlmittel innerhalb des U-Rohr-Systems in flüssiger Phase bis in unmittelbare Nähe des tiefsten Punktes des Naturumlaufsystems ohne Wärmeaufnahme geführt wird.To solve this problem it is proposed according to the invention that the cooling process in high pressure steam coolant to be transferred within the U-tube system in the liquid phase down to the immediate vicinity of the deepest Point of the natural circulation system is performed without heat absorption.
Durch diese verfahrenstechnische Maßnahme wird sichergestellt, daß mit beginnender Phasenänderung des Kühlmittels Strömungsstörfaktoren, hervorgerufen durch z.B. Dampfbildung im beheizten abwärts führenden Fallrohr, ausgeschaltet werden. Die sich aufgrund der Wärmeaufnahme ab dem tiefsten Punkt einstellende Phasenänderung erfolgt in einem strömungsstabilen Bereich, so daß der Naturumlauf in jedem Falle für den Wärmeaustauschprozeß sichergestellt ist.This procedural measure ensures that as the phase change of the coolant begins Flow disruptive factors, e.g. caused by the formation of steam in the heated downpipe, eliminated will. The phase change that occurs due to the heat absorption from the lowest point takes place in a flow-stable area, so that the natural circulation is ensured in each case for the heat exchange process.
