OPTIMIZATION OF TECHNOLOGICAL PARAMETERS FOR FUEL ROLL PRODUCTION USING AGRICULTURAL CROP STEM BIOMASS

The paper develops a regression model to predict the density of Fuel Rolls produced from Agricultural Crop Stem Biomass. The study evaluates the influence of Variable-volume Pressing Chamber pressure (P, MPa), biomass volume per linear meter (V, m³), and flax stem content (m, %) on Fuel Roll density (ρ). The goal is to optimize these parameters to ensure the desired density of Fuel Roll. A regression analysis combined with response surface methodology was employed. The optimal parameters for Fuel Rolls production include Variable-volume Pressing Chamber pressure of 0.45–0.55 MPa, biomass volumes of 0.65–0.75 m³/m and flax stem content 75%. These technological parameters enable the production of fuel rolls with required density of 110-130 kg/m³. The results show that increasing pressure in the Variable-volume Pressing Chamber enhances Fuel Roll density, while larger biomass volumes lead to lower densities. Additionally, higher flax stem content improves cohesion and compaction, resulting in higher densities. These findings emphasize the importance of fine-tuning technological parameters to optimize Fuel Roll production. Utilizing agricultural crop stems for biofuel production offers significant environmental benefits, including reduced agricultural waste and lower combustion emissions.
