Fluidized bed technology serves many purposes in industry which involves interaction between solid particles with gases and liquids. The most vital component in a fluidized bed system is the distributor which governs the rate of solid-fluid contact as well as the fluidization quality. One of the relatively new types of distributor is the annular distributor. The aim of the present work is to evaluate experimentally the performance of several configurations of the annular distributor by considering the pressure drop, ?p, as the performance criterion. The distributor has been studied by varying the number of blades (60 blades and 30 blades), varying the centre bodies in the bed (cone and cylinder) and by using different over-lapping blade lengths (O/L) while increasing the fluidizing gas velocity. The main findings show that the annular distributor exhibits similar characteristics as multi-orifice distributor as reported by Geldart and Baeyens. The distributor pressure drop increased exponentially with superficial air velocity, with little influence from the type of centre body used. On the other hand, the number of blades affects the distributor pressure drop significantly. The most desirable feature in fluidized beds - having low distributor pressure drop yet having good fluidization quality has been successfully achieved. The distributor to bed pressure drop ranging from 0.2 to 0.5 has been obtained in the current work, which is particularly low and ideal to reduce total energy consumption of the system. In conclusion, the annular distributor is found to be ideal for batch processing, particularly with low bed heights.
