Influence of the external heating on the particle adhesion and specific charge in the fluidized bed has been investigated. The adhesion amount on an internal wall of the fluidized bed had a maximum value along the distance from the inlet up to TS = 60°C. The specific charge increased with the heating temperature up to 60°C. On the other hand, the particles agglomerated at almost softening temperature (80°C) and then both the adhesion mass and the charge were lower than that at 20°C < TS < 60℃. Dependence of the water content in the particles on the particle adhesion and specific charge in the fluidized bed has been also investigated. The initially humidified particles agglomerated due to the liquid bridge force and motion of them could be suppressed at TS = 60°C. So that, the adhesion mass and the charge of the initially humidified particles were lower than that of the initially dried particles.
