Abstract:
With the growing concern of the world community with the environment, this work was carried out from the identification of an environmental problem, the high concentration of greenhouse gases. After identifying some possible solutions to this problem an alternative would be use them as an energy source in the process of reduction of iron ore in blast furnaces, with a feasible solution for carbon sequestration. This project aimed to use elephant grass (Pennisetum purpureum) and coal in the pulverized injection into tuyeres of the blast furnace in the steel plant. The elephant grass is a renewable source and through photosynthesis captures carbon dioxide from the atmosphere, reducing the pollution caused by the blast furnace. To simulate the possibility of injecting the materials studied, a physical modeling is used, which has been developed for this purpose. Other techniques are used to characterize the materials as size classification, combustion, calorimetry, gas analysis, microscopy, surface area, immediate and elemental chemical analysis. So, in theory, this research attempts to show that elephant grass through its injection into blast furnaces proved to be technically feasible, and it can be a way to reduce costs due to the partial replacement of fuel inputs already used and reduction of greenhouse gases.
