Abstract Scope |
The effect of steam injection on emission reduction and the quality index of sintering were studied. The sintering cup test showed that steam injection on the sintering bed surface has the effect of reducing NOx. It was also beneficial to reduce fuel consumption and the emission of SO2. After steam injection, the sinter drum index is slightly increased, the solid fuel consumption in sintering reduced by 1.64kg/t, and the ratio of 5-10mm sintered ore reduced by 0.8%. The steam injection improved the sinter quality and reduce the solid fuel consumption. Furthermore, the effect of steam injection in the middle part of sintering process was the most significant. |
