Theoretical Analysis of Sintering Operation

Abstract

On the basis of a mathematical model developed for the sintering process, the effects of operating variables, such as the temperature and oxygen concentration of gas in the ignition furnace, the residence time in the furnace, the mass velocity of gas, the diameter and temperature of solid particles to be fed, the mass fraction of coke in burden materials and the voidage of the bed, on the temperature distributions in the sintering bed are estimated from numerical calculations with the aid of a digital computer. Furthermore, a theoretical analysis on the optimum pallet speed to obtain a maximum production rate in Dwight-Lloyd sintering process is developed, and the equations for the optimum pallet speed, the maximum production rate and the mean yield are proposed in terms of the expressions for the definitions of sintering velocity and sintering time.
