TREATMENT OF PARTICULATE MATERIAL BY EMPLOYING FLUIDIZED BED PROCESS, TANK AND APPARATUS FOR MAKING THE SAME |
摘要 |
<p>In a method for treating particulate material in the fluidized bed method, the particulate material is maintained in a fluidized bed by a treating gas flowing from bottom to top and thereby is treated. To minimize the consumption of treating gas and to reduce entrainment of fine particles by the treating gas, a particulate material having a wide grain distribution and a relatively high portion of fines is used for treatment and the treating gas in the fluidized bed is maintained at a superficial velocity less than the velocity required for fluidizing the largest particles of said particulate material.</p> |
