In this paper, the differences in mechanical strength tested during static tensile and compression test of Scots pine (Pinus sylvestris L.), European larch (Larix decidua) Norway spruce (Picea abies) wood exposed to continuous soaking water with a salinity 7‰ were determined. The value corresponded average on Polish Baltic coast. This paper also aimed examine content mineral compounds absorbed four cycles two weeks each. essence statistical research was identify effect range salts depending wood. Based results experiments, it can be concluded that medium used has specific species’ structure. effects parameters depend obviously type A pine, as well other species, enhanced by incubating seawater. native sample’s initial mean 82.5 MPa, which increased 94.8 MPa last cycle. It found had lowest difference (9 MPa) woods studied current study. Four six necessary notice an increase strength.

Particle size and shape effect of Crumbler® rotary shear-milled granular woody biomass on the performance of Acrison® screw feeder: A computational and experimental investigation

Powder Technology, Journal Year: 2023, Volume and Issue: 427, P. 118707 - 118707

Published: June 8, 2023

Physical experiments and discrete element model (DEM) simulations are conducted to evaluate particle characteristics operation parameter effects on screw feeding performance for rotary shear-milled Douglas fir. Three metrics used: mass flow rate, shaft driving torque, specific energy consumption. The impact of size, size distribution (PSD), rotational speed (rpm), hopper dimensions the investigated. All employed reveal superior flowability 2-mm particles in contrast larger 6-mm counterpart. Remarkably, wider PSD results poorer than two mono-sized particles, proving enhancement achieved by narrower woody feedstock. More importantly, DEM unveil PSD-induced degradation is attributed mechanical interlocking segregation effects. Furthermore, higher rpm causes rate at cost consumption due viscous dissipation changes pattern.

Go with the Flow: Additives to Improve the Flowability of Crumbled Corn Stover

ACS Sustainable Chemistry & Engineering, Journal Year: 2025, Volume and Issue: 13(2), P. 731 - 736

Published: Jan. 9, 2025

Magnesium stearate (MgSt), a common flow additive and anticaking agent, was applied to corn stover feedstocks with three particle sizes. The material handling properties of dry, 15%, 30% moisture content were measured Freeman FT-4 powder rheometer mass hopper calculations. While hydrated biomass typically exhibits poor flowability, introducing MgSt led significant increase in flowability for dry 15% feedstocks, less impact at content. Inverse gas chromatography showed decrease, up 40%, the surface energy MgSt-coated stover. may not be ideal biofuel or chemical production, this study highlights potential additives reduce adhesive cohesive forces, improving feedstock handling.

The role of flexural particles in the shear flow of pine residue biomass: An experiment-informed DEM simulation study

Powder Technology, Journal Year: 2024, Volume and Issue: 440, P. 119771 - 119771

Published: April 17, 2024

An experiment-informed discrete particle simulation study was performed to investigate the role of flexural particles in shear flow milled pine residues. Physical anatomical fraction samples were tested an FT4 powder rheometer. A chip model for bark/stem chips and a fiber needles proposed DEM. The simulations show mixed fibers/chips require higher force torque drive than pure or fibers. mass flexibility fibers reveal nonlinear inter-dependency on impacting fibers/chips. Polydisperse well match needle-rich attributes, while polydisperse agree reasonably with bark/stem-rich samples. DEM indicates that flowability residue biomass is determined collectively by various material attributes fractions, which must be considered when developing preprocessing methods conversion-ready adequate handling performance.
