Bed Model for Grate-Fired Furnaces: Computational Fluid Dynamics Modeling and Comparison to Experiments
(Peer reviewed; Journal article, 2022)A detailed but still central processing unit (CPU)-efficient bed model for grate-fired combustion of biomass and waste is developed. Simulations of wood chip combustion are performed, and the results are compared to ... -
Biocarbon Production via Plasticized Biochar: Role of Feedstock, Water Content, Catalysts, and Reaction Time
(Peer reviewed; Journal article, 2023)Studies into transient plastic phase biochar (TPPB) were conducted to compare how feedstock, moisture, acetic acid addition, and reaction time impacted the formation of TPPB and mechanical properties. Our results show that ... -
Carbonization of biomass in constant-volume reactors
(Journal article; Peer reviewed, 2017)A novel carbonization process that realizes near-theoretical fixed-carbon yields in ∼3 h is presented. Norwegian spruce and birch sawdusts were carbonized in a hermetically sealed reactor at an initial nitrogen pressure ... -
Charcoal "Mines" in the Norwegian Woods
(Journal article; Peer reviewed, 2016)This paper presents lab-scale flash carbonization (FC) experiments under elevated pressure using Norwegian wood as a feedstock. The silicon and ferrosilicon industry of Norway has been urged to reduce fossil CO2emissions ... -
