Abstract

The blast furnaces of Western Europe are fed with 50 to 90% sinter, making it the most important blast furnace burden material. The sintering process uses huge amounts of air, consequently producing huge amounts of flue gases that contain dust, SO2, NOx and dioxins. Although the concentrations of pollutants are low, the total amounts of flue gases produced are so high that this type of pollution constitutes a considerable part of the total pollution from an integrated iron and steelwork. Current options for reducing flue gas emissions include installation of a gas cleaning plant, or a decrease in sinter production. As neither option is economically attractive, a new method is desirable. The report details the development of a method for reducing the amount of flue gases for a given level of sinter production. The new process, Emission Optimized Sintering, reduces gas emission by recirculating part of the flue gas.
