摘要
A simple pseudo steady-state receding core model was used to analyze the data from this study as well as data available from the literature. The model showed that particle shrinkage during drying had little affect on the dimensionless drying curves provided that shrinkage did not cause the particle to fragment or to limit mass transfer. The model was in agreement with drying data using Mississippi lignite, Australian brown coal and Montana subituminous coal.
