Effect of Promotor and Distributor Parameters on the Performance of Gas-solid Fluidized Beds

Abstract

In the present case, an extensive experimentation has been conducted to study the combined effect of promoter and distributor parameters on bed dynamics relating to minimum fluidization velocity, bed pressure drop, bed expansion and fluctuation. A total of three different types of promoters viz. rod type (four number of varying rod configuration and blockage), disk type (eleven number of varying disk thickness and diameter) and one blade type have been used in the investigation. Other system variables include gas distributor (five number of different opening area), bed materials of different size and density and initial static bed height.
