Abstract
Among the mechanism and kinetics of iron oxide reduction and coke gasification reaction reported, only the reactions under isothermal condition or iso-gas compositions are reported. Very few papers are published concerning non-isothermal reactions. In this papers, experiments for the reduction of wustite along with the coke gasification were performed under the simulated conditions of thermal reserve zone of iron blast furnace which is apparently non - isothermal and non iso-gas composition. The main object of this research is to probe the rate and effect of alkaline metal additions on the wustite reduction and coke gasification. Temperature and gas compositions are varied to simulate the running conditions of old type and modern type blast furnace. Gas utilization factor is introduced to explain the abundancy or the shortage of the reducing gases in the blast furnace running conditions.
