Fluidization behavior of biomass particles and its
The minimum fluidization velocity of sand-3 (60 to 80 mesh) alone was coincident with biomass and exhibited superior fluidization quality in comparison with sand-1 (30 to 40 mesh) and sand-2 (40 to 60 mesh). The proportion of sand-3 in biomass/sand-3 mixture was found to be the main factor contributing to the fluidizing quality of a bed.
