Validation of a Multiparameter Model To Investigate Torrefied Biomass Pelletization Behavior
The present study aims to apply and validate a simple model describing the forces that are built up along the dies of a pellet press matrix to the pelletization of torrefied biomass. The model combines a theoretical background with the use of a single pellet press to describe the pelletizing behavior of torrefied material in an industrial-scale pellet mill. Wet torrefaction and dry torrefaction pretreatments are considered in the study.
Both torrefaction concepts produce a fuel with enhanced properties, including a lower moisture content, higher calorific value, and better friability. The fuel shows closer properties to coal, and it is more economical to transport and better to store as a result of its hydrophobic characteristics. The goal of the present study is to allow for a fast estimation of important pelletization process parameters, to obtain a better understanding of the pelletization process, and to avoid time-consuming and expensive trial and error experiments.
