Abstract
Using the simulation model of the Imperial Smelting Furnace based on differential heat and materials balances developed by the authors, the behavior of ISF under various operating conditions was predicted, where the influence of change in an operating condition on furnace performance was estimated. The main findings are as follows:
(1) With decreasing coke reactivity, zinc productivity increases and coke ratio decreases.
(2) There are an optimum size of particle and an optimum height of charge for the furnace performance.
(3) Pulverized coke injection improves the furnace performance.
Analysis of furnace performance using the model is useful for further improvement of the furnace operation.
