: “METHOD FOR TREATING PARTICULATE MATERIAL IN THE FLUIDIZED BED METHOD AND VESSEL AND PLANT FOR CARRYING OUT THE METHOD”
Application 1219/DEL/1997 published 2006-05-12, filed 1997-05-12
In a method for treating particulate material in the fluidized bed method, the particulate material is maintained in a fluidized bed (2) 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 superficial velocity of the treating gas in the fluidized bed (2) is kept to be smaller than the velocity required for fluidizing the largest particles of said particulate material.
