Mechanism of Selective Desulphurization in Iron Ore ...
Feb 01, 2017 Iron ore sintering is an important part during the ironmaking process, and a large amount of SO 2 is also generated. Our previous research shows that it is an effective way to reduce SO 2 content of flue gas by adding urea to a special sintering material zone position. In this paper, the mechanism of selective desulphurization by adding urea during the iron ore sintering was carried out.

Nov 08, 2016 高达10%返现 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 pilot-scale experiment was carried out in a commercial sintering plant.
