Abstract. The iron ore sintering process is the main source of SO 2 emissions in the iron and steel industry. In our previous research we proposed a novel technology for reducing SO 2 emissions in the flue gas in the iron ore sintering process by adding urea at a given distance from the sintering grate bar. In this paper a pilotscale experiment was carried out in a commercial sintering plant.
