METHOD FOR REDUCING THE CARBON DIOXIDE EMISSIONS OF A BLAST FURNACE, AND ASSOCIATED DEVICE

摘要

The present disclosure relates mainly to a method for reducing the carbon dioxide emissions of a blast furnace, in which reducing agents are charged into the throat and auxiliary fuels in pulverized form are injected into the tuyeres, and which is essentially characterized in that the reducing agents charged into the throat comprise charcoal. According to a preferred aspect of the disclosure, the specific consumption of charcoal charged into the throat is more than 0% and less than 20% of the total quantity of reducing agents charged into the throat. By proceeding in this matter, a significant reduction in carbon dioxide emissions is obtained, and also substantial beneficiation of the charcoal relative to the reduction in carbon dioxide emissions. The present disclosure also relates to a device for implementing this method.
