Development And Applications Of A Novel Intermittent Solids Feeder For Pyrolysis Reactors, Federico M. Berruti
Electronic Thesis and Dissertation Repository
This PhD research addresses the challenge of feeding biomass residues into fluidized bed reactors for pyrolysis, through the development of a novel intermittent solid slug feeder, both for laboratory-scale and large-scale reactors. The new feeder can successfully handle biomass residues that are either too cohesive or thermally sensitive for traditional feeders.
To optimize the novel feeder performance, a model for the pulsating solids flow was developed from experimental data collected with ideal slugs, as well as real biomass flow. The model was validated using both a laboratory-scale (< 10 kg/hr) and large-scale feeder (> 250 kg/hr). Several important variables were identified. They include the material flow ...
