| titleOfInvention | Ore blending method for effectively reducing NOx emission in sintering process |
| abstract | The invention discloses a combined method for effectively reducing NOx emission in a sintering process, which comprises the following steps: firstly, sintering the whole coke powder, controlling the proportion of less than 3mm in the coke powder to be more than 90%, and particularly controlling the proportion of 1-3 mm in the coke powder to be 75-80%; secondly, controlling the use proportion of magnetite concentrate in the ore blending structure to be 10-18 percent; thirdly, controlling the use proportion of the hematite to be less than 30 percent in the ore blending structure; fourthly, mixing iron scale with a certain proportion into the ore mixing structure, and controlling the use proportion to be 2-5%; mixing the fuel, the iron-containing raw material and the flux in proportion to form a mixture, adding water, uniformly mixing, granulating, distributing, and igniting and sintering. On the premise that a sintering flue gas denitration process is not available, sintering flue gas NOx source control is implemented, and process emission reduction is carried out on the premise that a sintering process meets increasingly strict environmental requirements, so that the environmental compliance risk of steel enterprises is reduced. |
