Title: FLUIDIZED CALCINING PROCESS
Abstract:
A method for enhancing the efficiency of a thermal process such as calcination. The incoming solid particulate material (10) is preheated in the conveyor (32) by partially cooled exhaust vapors (36) from the thermal processor (20). In passage through the conveyor (32), the cooled, intermediate temperature vapors contact, fluidize and heat the particulate solids (10) to increase the available throughput of the system (14).
