Effects of binder choice in converter and blast furnace sludge briquette preparation: Environmental and practical implications

Original language description

Blast furnace and converter sludges are fine-grained waste materials characterized as dangerous wastewith a negative impact on the environment. One way of recycling of such materials is briquetting fol-lowed by reuse of the material in the blast furnace. In the briquetting process, an important step is thechoice of the binder suitable for manufacturing the briquettes with suitable mechanical properties. In thiswork, the effect of the binder choice (laundry starch UNIPRET, Portland cement) on the reduction of ironoxides in the assessed waste materials during thermal treatment (900, 1000, 1100 oC) is evaluated.Simultaneously, the effect of the binder choice on the amount and composition of the resulting wastegas was evaluated as well as its possible impact on the environment. The performed experiments provedthe mutual relationship between the level of iron oxides to metal iron conversion, the binder content andretention temperature. Type of binder also affected the volume of the resulting waste gas. Factor analysisfor mixed data (FAMD) proved that the resulting concentrations of the assessed hydrocarbons were cor-related (apart from ethyne) and that they are closely associated with the binder applied. Conversely, theconcentrations of ethyne, carbon monoxide and carbon dioxide were not associated with the binder butwith the retention temperature. FAMD did not show any direct effect of final retention temperature onthe amount of the rest of the resulting hydrocarbons. In comparison with the starch-containing bri-quettes, the cement-containing briquettes were also proved to lead to lower resulting concentrationsof PAHs in the waste gas.
