Modelling of thermal processes in a biomass compression process

Biomass residues are increasing their share as a feedstock for renewable heat and power systems. Agricultural biomass is available in large quantities but to be utilised in energy systems the bulk density of the material should be increased. Large number of process parameters influence biomass compression process and thus effecting machinery efficiency and particular energy consumption. In the paper the influence of temperature on biomass compression process performance in a dedicated machinery for biomass compression has been analysed. Mathematical model that describes thermal processes in a biomass material and compression chamber has been devised. Influence of friction heat in compression chamber on biomass thermal properties has been simulated. Measurement data for model development and verification has been collected from a biomass compression machine during dedicated field tests.
