Abstract

The technical contribution is going to study the alternative mixtures of sugar cane bagasse with charcoal for injection in the tuyeres of blast furnace. It was done six mixtures of the charcoal varying the percentages at 20%, 40%, 60%, 80% and, finally 100% of sugar cane bagasse. The sugar cane bagasse is already used for generation of thermal energy in boilers, as source of electric energy, and now it is being studied a possible utilization for powder mixture injection into blast furnaces. The use of renewable fuels for the output of primary iron is being discussed a lot at the last times, aiming at an environmentally sustainable steel industry. In this sense, the use of biomass as flammable agent and fuel for iron oxide reduction looks to be an efficient route for output of primary iron of environmentally sustainable and economic way. Because, from the substitution of the use of fossils fuels by biomass, produce a cycle closed of generation and the capture of CO2.
