Abstract

Cohesive particulate materials, even those that belong to the Geldart A group, present some difficulties to fluidize in conventional equipment. The rotated pulsed fluidized bed (RPFB) can be used to pulse the gas flow through the distributor plate to minimize difficulties. In this work, the used gas is at T ambient and the parameters used during the fluid dynamics studies were: C solids and F disk rotation. The fluid dynamic curve was analyzed with the variation of these parameters, and the best condition for the pulse fluidization of the bed was determined. The fluid dynamic curve obtained for the RPFB was compared with the conventional fluid dynamic bed curve. A smoothness of the curve for the RPFB was observed, and as a consequence, a decrease of the APbed during the process. A comparison between the RPFB and the mechanically agitated fluidized bed (Ambrosio, 1999) was also done and it was verified that the pressure drop in both systems are very close during the process
