The qualitative effect of temperature on the particle entrainment rate has been measured in a gas fluidized bed (0.1 m i.d., 1.97 m height). The gas velocity (0.65-2.3 m/s), the bed temperature (12-600 degrees C), the particle density (2509-6158 kg/m(3)), and the particle size (0.091-0.363 mm) were considered as experimental variables. The particle entrainment rate increased after an initial decrease with increasing bed temperature. The effect of temperature on particle entrainment rate decreased as either the gas velocity or the particle density increased. Within the experimental range, it could be confirmed that the change of the particle entrainment rate with temperature was very similar to that of the particle size for which the terminal velocity was equal to the gas velocity.
