Design and performance evaluation of a novel biomass
a model for biomass screw feeding for the torque requirement of a screw feeder by considering the bulk solid mechanics of a material element within a pocket. Screw or piston operated plug feeders, common in feeding coal, have also been tested with biomass3-10. In screw feeders, lacks of flow is a common phenomenon and have serious solids

Biomass granular feeding for gasification and combustion
Successful feeding is critical to biomass utilization processes, but is difficult due to the heterogeneity, peculiar physical characteristics and moisture content of the biomass particles. The objectives of this project were to define what limits screw feeding in terms of the mechanisms of blockage and to examine the effects of key properties like mean particle size,
