Abstract
The injection of pulverized materials in blast furnaces is a
technique that has been used in iron making for reducing costs with
reducing fuels and allows greater operational control. To be injected, the
material needs some chemical, physical and thermal characteristics for the
process. However, biomass presents as an economical and
environmentally viable alternative to replace part of the coal used in this
process. One variable analyzed in the reduction process is the replacement
rate (RR), which is the amount of coke saved loading on the top of the
reactor per quantity of material injected. There are some mathematical
models for calculating the replacement rate based on properties, which are
results of studies in determined blast furnaces. This work will show some
calculations for replacement rate of biomasses using formulas from the
literature. Some results show the technical feasibility for the use of
biomass in blast furnaces.
