AbstractConverter steelmaking produces a large amount of high-temperature flue, which contains pollutant gases (SO(2), HF, etc.) and entrains fine dusts (Fe, FeO, Fe(2)O(3), CaO, etc.), and fluorine and sulfur behaviors that were affected by dusts in off-gas are estimated by chemical equilibrium method. The behaviors of fluorine and sulfur in off-gas are very different at reducing and oxidizing atmospheres. At a reducing atmosphere, main fluorides in off-gas are SiF(4)(g), CaF(2)(s), HF, and CaF(2)(g); the main sulfides are FeS(2)(s), FeS(s), COS(g), SO(2)(g), and S(2)(g); and CaO can effectively defluorine at T < 1000 K. At oxidizing atmosphere, main fluorides are SiF(4)(g), HF, and CaF(2)(g); the main sulfides are Fe(2)(SO(4))(3)(s), CaSO(4)(s), SO(2)(g), and SO(3)(g); and defluorination and desulfurization by dusts are completely effectively at MR >= 1 and T < 1100 K.
