Resumo

Trends in the steelmaking industry indicate a need to substitute the use of charcoal in the production of the pig-iron for new energy sources in current blast furnace processes. This article studies ICP (Injection of powder charcoal) with the incorporation of the rice rind to the fine of charcoal used in the pig-iron production. The simulation equipment was used to consider the peculiarities of these reactors. Within this context, the effects of the mixture of charcoal and rice rind are correlated with the combustion rate and the injection rate. In conclusion, the injection rates have values that are close to the combustion rates. Therefore, the product is available even if the injection rate is high.
