CHARACTERIZATION OF THE FLUIDIZATION AND MIXING OF BINARY MIXTURES CONTAINING BIOMASS AT LOW GAS VELOCITIES

摘要

To judge qualitatively the effect of biomass properties on its fluidizability and mixing tendency with sand particles at low fluidization velocities, local pressure gradients in the top and bottom of the bed were compared for all investigated systems. It was found that changing the mass fraction and the size of biomass impacted the onset of bubbling and the size of bubbles across the bed, which, in turn, affected the mixing/segregation of the bed content.
