Construction data for the immersion heater in the gas generator WKV to calculate the hydrogen and Tritium Permeation
Description
Automatic translation: Exact temperature specifications for each point of the heat exchanger coils are not possible at the moment, because the Heat transfer in the gas generator because of the meander shape of the Coiled and countercurrent flow coils are superimposed on simultaneous horizontal transport of solids and decreasing gasification capacity towards the end of the reactor, whereby overall the detailed calculation of the heat transfer is very complicated. At an extensive Computer model to simulate the conditions in the gas generator is currently being used. worked. However, today temperature limits as well as temperature mean values can be specified, which are provisionally to be regarded as sufficient for the calculation of permeation rates for hydrogen and tritium in the context of the PNP concept phase.
Abstract (German)
Genaue Temperaturangaben für jeden Punkt der Wärmetauscherschlangen sind augenblicklich nicht möglich, da sich beim Wärmeübergang im Gasgenerator wegen der Mäanderform der Rohrschlangen Gleich- und Gegenstromprinzip überlagern bei gleichzeitigem horizontalem Feststofftransport und abnehmender Vergasungsleistung zum Reaktorende hin, wodurch sich insgesamt die detaillierte Berechnung des Wärmeübergangs als sehr kompliziert darstellt. An einem umfangreichen Computer-Modell zur Simulierung der Verhältnisse im Gasgenerator wird z.Z. gearbeitet. Allerdings können heute Temperaturgrenzen wie auch Temperatur-Mittelwerte angegeben werden, die vorläufig zur Berechnung von Permeationsraten für Wasserstoff und Tritium im Rahmen der PNP-Konzeptphase als ausreichend anzusehen sind.
