| Abstract | ||
| The objective of the present study was to determine the effects of the internals baffles on the gas-solids fluidized bed hydrodynamics, using a circular fluidized bed of Geldert group B sand particles. Bed expansion data were obtained for un baffled and two different types of baffled (rectangular and circular blades) gas-solids fluidized beds at varying operating conditions, namely air velocity ,particle size (755,424 , 205µm) and initial static bed heights. Experimental work was carried out in (0.1m) diameter and (1m) height circular fluidized bed column. The results of the study showed that the particle size affects the measured hydrodynamic behavior especially in the large particle size. The insertion of baffles into a fluidized bed system improves the contacting efficiency of gas and particle phases. The effect of rectangular baffles is more significant than the effect of circular baffles on the pressure drop in fluidizing bed. | ||
