摘要：

The effect of fine particles on minimum fluidization velocity and bubble size at high temperatures was investigated, using ceramic beads with bimodal particle size distributions. Minimum fluidization velocity was determined by the pressure-drop method and bubble size was measured by the VTR method. Minimum fluidization velocities were found to decrease with increasing fine particle content in the fluidizing particles and with rising temperature as predicted. Also, bubble size decreased with increasing fine particle content. No effect of temperature on bubble size was observed in the fluidized bed using ceramic beads.
