Flowability of Crumbler Rotary Shear Size-Reduced Granular Biomass: An Experiment-Informed Modeling Study on the Angle of Repose
Abstract Biomass has potential as a carbon-neutral alternative to petroleum for chemical and energy products. However, complete replacement of fossil fuel is contingent upon efficient
Measurement of Transport Properties of Woody Biomass Feedstock Particles Before and After Pyrolysis by Numerical Analysis of X-Ray Tomographic Reconstructions
Abstract Lignocellulosic biomass has a complex, species-specific microstructure that governs heat and mass transport during conversion processes. A quantitative understanding of the evolution of pore
Investigation of Cutter-Woodchip Contact Pressure in a New Biomass Comminution System
Abstract A Crumbler® rotary shear system was recently developed to process fuel-grade woodchips into feedstocks having more uniform particle sizes for improved flowability and higher
Processing Powerline Vegetation Management Biomass for Use in Distributed-Scale Gasifiers
Pacific Gas and Electric (PG&E) sponsored a project to explore methods to gather powerline vegetation management woody biomass and process it into feedstocks optimized for delivery to distributed-scale gasifiers. A pilot study was conducted in Lake County, California where powerline trimmings were either chipped or baled, then ground at a central biomass processing facility, and finally milled / screened to achieve particle size distributions specified by a gasifier manufacturer. The vegetation included oak, pine, walnut, and other hardwoods. All materials were successfully processed into feedstocks.
