Method for reducing emission of nitrogen oxides in iron ore sintering process

The invention discloses a method for reducing emission of nitrogen oxides in an iron ore sintering process, and relates to the technical field of emission reduction of sintering pollutants. The methodcomprises the following steps: adding quicklime to a fuel under a water-free condition, performing dry mixing to prepare a modified fuel, mixing the modified fuel with an iron-containing raw materialand a flux, performing granulation to obtain a mixture, spreading the mixture on a trolley, and carrying out ignition and exhaust sintering on the mixture. The quicklime and the fuel are sufficientlydrily mixed to make the quicklime loosely distributed surrounding the fuel; and nitrogen oxides are generated in the combustion process of the fuel, and the loosely distributed quicklime can efficiently catalyze the reduction process of the nitrogen oxides in order to achieve the efficient reduction of the emission fo the nitrogen oxides in the iron ore sintering process. 本发明公开了种铁矿烧结过程氮氧化物减排方法，涉及烧结污染物减排技术领域。本发明首先在不加水的条件下将生
