本工作的重点是在实验室规模的试验装置的生物质和砂的混合物的流化行为的研究。在实验期间使用的生物质材料是稻壳、甘蔗渣和锯末。在形成混合物中使用两种不同粒度的硅砂。混合物中生物质的百分比为2重量%、5重量%、10重量%和15重量%。在透明流化床塔中，通过实验找出了二元样品的最小流化速度。最小流化速度的实验值与文献中的关联式进行了比较。在不同的操作条件下，也测量了整个流化床的压降，并对这些数据进行了分析，以解释流体动力学行为。
The present work is focused on the study of fluidization behaviour of biomass and sand mixtures in a laboratory scale test set up. The biomass materials used during the experimentation were rice husk, bagasse and sawdust. Two different particle sizes of silica sands were used in forming the mixture. The percentages of biomass in the mixtures were 2%, 5%, 10% and 15% by weight. The minimum fluidization velocities of the binary samples were experimentally found out in a transparent fluidized bed column. The experimental values of the minimum fluidization velocities were compared with the correlations available in literature. The pressure drops across the fluidized beds were also measured at different operating conditions and such data have been analyzed to explain the hydrodynamic behaviour.
