The chapter presents the results of theoretical analysis and practical implementation of small blast furnaces operation using a charge of ore-carbon agglomerated products (briquettes and unfired pellets on a cement binder). It is shown that the use of such charge materials in the blast furnace charge leads to a decrease in the total fuel consumption and a proportional decrease in CO2 emissions. Particular attention is paid to modeling the kinetics of carbothermic processes in a blast furnace based on mathematical modeling and simplified methods of generalized calculation.

摘要

The chapter presents the results of theoretical analysis and practical implementation of small blast furnaces operation using a charge of ore-carbon agglomerated products (briquettes and unfired pellets on a cement binder). It is shown that the use of such charge materials in the blast furnace charge leads to a decrease in the total fuel consumption and a proportional decrease in CO2 emissions. Particular attention is paid to modeling the kinetics of carbothermic processes in a blast furnace based on mathematical modeling and simplified methods of generalized calculation.
