For about 10 years the steel industry in Brazil has been using pulverized coal injection (PCI) technology in blast furnaces based on imported coals. In order to decrease the dependence on imported coals, Brazilian coal which has limited use due to high ash content is suggested to be mixed with imported coal and charcoal. The aim of this study is to examine the reactivity and combustion behaviour of the mentioned materials. The use of charcoal in the Brazilian steel industry reduces the CO 2 emissions, since it represents a renewable source of carbon. The reactivity of the coal, charcoal and mixtures is evaluated through TGA. To provide a useful insight into the practice of PCI in blast furnaces, experiments are carried out with a laboratory rig at RWTH Aachen University that simulates the behaviour of fines injected into the raceway. The results of this study are presented and discussed.

For about 10 years the steel industry in Brazil has used pulverized coal injection (PCI) technology in the blast furnaces based on imported coals. In order to decrease the dependence on imported coals, Brazilian coal, which has limited use due to high ash content, was suggested to be mixed with imported coal and charcoal. The aim was to examine the reactivity of the samples. The charcoal use in the steel industry contributes to the CO 2 emission reduction, since it represents a renewable source of energy. The reactivity of the coals, charcoal and mixtures was evaluated through simultaneous thermal analyses. Results of this study are presented and discussed.
