“…Therefore, for using the BFS waste outside the steel plant is necessary to characterize its effects in terms of both, energetic contribution and liberation of gases during the ceramic firing. In particular the CO 2 emission, as greenhouse gas responsible to the global warning, is important to be evaluated [4,5]. By bits amount of carbon, the BFS can be considered a fuel containing waste and would favorably contribute to the ceramic firing process.…”
Operation in an integrated steel making plant, such as the processing of iron ore by blast furnace result in several wastes that need to be conveniently disposed to avoid environmental pollution. In the case of sludge wastes, a feasible solution is their addition to clayey ceramics. The objective of this work was then to characterize a steel making plant waste was subjected to mineralogical, chemical and physical tests. The combustion gases: CO, CO2, NO and SO2from thermal emission were analyzed. It was found that the blast furnace sludge has a high content of both iron and carbon. Its combustion generates enough heat to sensibly contribute to the firing of the ceramic, which is an energetical advantage associated with the sludge waste addition. The gas emission was monitored and, for relatively small addition of waste, no harm is apparently caused to the environment.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
