Abstract
A method for enhancing the efficiency of a thermal process such as calcination. The incoming solid particulate material is preheated in the conveyor by partially cooled exhaust vapors from the thermal processor. In passage through the conveyor, the cooled, intermediate temperature vapors contact, fluidize and heat the particulate solids to increase the available throughput of the system.
