Abstract

The reduction of energy consumption in the blast furnace is still the subject of investigations using mathematical modelling of a blast furnace plant. Theoretical-empirical hybrid models of a blast furnace and its equipment have been presented. This model is built based on the mass and energy balances of furnace zones and empirical data from the measurement of a blast furnace. The results of a numerical simulation of the injection of auxiliary fuels and the top-gas recirculation after the removal of CO₂ to the blast furnace have been presented.
