Resumo

This paper aims the study and the characterization of a mixtures of sugarcane bagasse and coal for their injection through tuyeres of blast furnaces, in order to a possible replacement of fossil fuels commonly used for injection into coke blast furnaces. The methodology applied can be divided in two steps. Firstly a characterization of the sugarcane “in natura” by chemical analysis, B.E.T: nitrogen adsorption and scanning electron microscopy performed on samples of the powdered material with the particle size ranging between 48 and 100 mesh. The second part consists of the study of the behavior of a mixture of sugarcane bagasse with coal when injected through the tuyeres. For this, were performed tests using a device that simulates the injection process, using a mixture of coal and bagasse varying only the percentage of sugarcane bagasse from 0% till 100%. Therefore, this paper shows that the mixture of sugarcane bagasse and coal can be an effective alternative for a clean development in the steel industry.
