Abstract
The present work aims to improve the understanding of the fundamental physicochemical phenomena involved in the zinc updraft sinter-roasting process and to develop a mathematical simulation model. Laboratory and pilot pan experiments have been performed to investigate some of the phenomena important to the process, such as gas flow through the sintering bed, moisture removal, roasting reaction kinetics, melting, and solidification. The mathematical model of the sinter-roasting operation has been developed based on the results of these specific studies and the coupling of the physical phenomena. The basic principle of the model is to solve dif-ferential balances of heat, mass, and momentum transport (by an implicit finite difference method) using parameters specific to each zone of the sintering bed. From input data concerning the operating conditions and the raw materials characteristics, the model calculates the temperatures and compositions of the solids and gases throughout the bed. Simulated and experimental results obtained for an actual pilot pan are presented and compared. Manuscript submitted May 10, 1991.
