Abstract
A model for calculating the minimum spouting flowrate and pressure drop in a conical spouted bed has been developed and described in our previous paper (Hadžismajlovi et al., 1986). In the present work, this model was examined at a wider range of experimental conditions and it was found that measured and predicted values of the minimum spouting flowrate and pressure drop differed by about 10.3% and 20.0%, respectively.
It is shown that the spouted bed in a conical column is stable when the inlet tube diameter is less than 25 particle diameters.
Un modèle visant à calculer le débit de jaillissement minimum et la perte de charge dans un lit à jaillissement conique a été mis au point et décrit dans notre dernier article (Hadžismajlovi et al., 1986). Dans le présent article, ce modèle a été examiné dans une large gamme de conditions expérimentales, et on a trouvé que les valeurs mesurées et prédites du débit de jaillissement minimum et de la perte de charge différaient d'environ 10,3 et 20,0 %, respectivement.
On montre que le lit à jaillissement dans une colonne conique est stable lorsque le diamètre du tube d'entrée est inférieur à 25 fois le diamètre des particules.
