Biomass granular screw feeding: An experimental …
Screw feeders used to feed biomass operate in a manner similar to piston feeders, but have a somewhat lower pres-surization range (0.5e1.5 MPa). In a screw feeder, an auger compresses the feedstock into a compact plug, aided by tapering the feed channel, or by gradually reducing the pitch of the screw. The feed plug then forms a barrier, preventing
