Abstract

A simulation model of the Imperial Smelting Furnace has been developed to improve the furnace operation. The model consists of top, shaft and bottom regions. Analysis in the shaft region is based on differential heat and materials balances taking account of reaction kinetics and heat transfer rate, and those in the top and the bottom regions are based on heat and materials balances under steady-state condition. Overall heat and materials balances, and longitudinal distributions of process variables such as temperatures of gas, sinter and coke, volume-flow rate of gas, mass-flow rates of sinter, coke and molten lead, gas composition and fractional conversion in the shaft region under a practical operating condition were calculated. The heat loss through the furnace wall and the temperature distribution calculated using the model are in good agreement with those observed. The model is capable of predicting any change in the furnace situation when the operating condition is altered.
