Resumo
Energy is the basis for the development of humankind. Most of the energy used worldwide comes from fossil fuels and their heavy consumption is presented as primarily responsible for the environmental impacts nowadays. In this context it is interesting to think about renewable energy sources in order to reduce these environmental impacts, specifically speaking, the use of biomass as a fuel. The trends of industry to replace the coal used in the production of hot metal indicates the necessity to think of new alternatives to using these types of materials, called biomass, in processes related to the blast furnace. This work studies the PCI (pulverized coal injection) with the addition of rice rind with particle size between 100 and 200 mesh as well being injected through the tuyeres of the blast furnace. The equipment used for this simulation takes into account the peculiarities of a blast furnace. Considering this context, it can be seen that the effect of the mixture of rice rind and coal, correlated with different injection rates and different rates of combustion, can be an efficient choice of clean development, ecological and economic development in the steel industry.
