Abstract

In this work the authors report the effect of increasing the annular area in a Swirling Fluidized Bed (SFB) by using longer blades for the distributor and compare it to the conventional blade length. Fluidized beds have been widely used in industrial processes. The inefficiency of current systems provides opportunities for improvement and development new fluidized bed techniques. The swirling fluidized bed is an outcome such a quest. The main shortcomings of present day SFB systems are the underutilization of available annular area and massing of bed particles at the periphery of the bed column. Distributor blades of two different lengths, 50 mm and 100 mm, was used in this work and the bed height was measured with spherical bed particle of three different size(4 mm, 5 mm, 6 mm) at varying bed weight and superficial velocity. For a given bed weight, the benefits are achieved through a lower bed pressure drop as well as better quality of fluidization.
