Mathematical modelling of sawdust drying process for biomass pelleting

Abstract The overall objective of this research is to conduct an analysis of biomass drying process. This paper investigates the effect of various drier inlet parameters such as sawdust moisture content, particle diameter and drying gas temperature on moisture content of dry sawdust and hot flue gases and their temperature profiles along the length of the dryer. Our simulations show that the overall drying rate increases when using sawdust with a more uniform particle size.
