A model for biomass screw feeding - ScienceDirect

2008/8/1 · In this paper, a model is presented to delineate what limits screw feeding in terms of the mechanisms of blockage and to predict torque requirements for biomass. Predictions are then compared with experimental results for wood pellets, ground wood pellets, sawdust, hog fuel, ground hog fuel and wood shavings, with temperature and thermal effects neglected.

Modeling Biomass Transport in a Compression Screw Feeder

Biorefineries which seek to convert biomass into ethanol face many different challenges, and among them, mechanical failure of equipment is common. Unfortunately, the resulting downtime can significantly reduce the profitability and the viability of bioethanol plants. One important piece of mechanical equipment in this setting is the compression screw feeder, which is used both to convey …
