Abstract


In sintering plants, gaseous emissions are generated wbich must comply with increasingly demanding environmental regulations. In the sintering process, about 40 kg of coke and1,700 Nm of air are used per ton of useful sinter. Sintering fumes have a gaseous phase formed mainly of N2, O2, CO2, H2O and CO and the minor components SO2, SO3, NO and NO2. Other minor components include unburned organic products and CIH, and minimal proportions of other high impact compounds such as dioxins and furans are also present. Chlorides and heavy metals are present in the solid fraction. This paper reviews the situation of each emission in relation with the applicable regulations, and the possible means of reducing these emissions.
