Abstract：Iron ore sintering is the main source emission of SO2 and NOx. And the simultaneous desulfurization and denitrification technology of iron ore flue gas was studied by using pre- oxidized and ammonia process. The results showed that the pre- oxidation of the flues gas and the increase of the initial content of SO2-3 and the pH value of the absorption liquid and the ratio of liquid to gas were conducive to improving the desulfurization and denitration rates. Increasing the temperature or content of SO2 and NOx of flue gas was adverse to the desulfurization and denitration rates. The final denitration products were N2 and NO-3 after the pre- oxidized and ammonia process.
