The wellknown Geldart's [25] powder classification system for gas fluidization was used by Geldart and Williams [26] to characterize the powder flowability on the basis of particle density and mean particle diameter. Under Geldart's criteria, the pulverized coal is a typical group C powder, characterized by poor flowability and strong cohesive forces.
