This paper takes major nitrogen oxides(NOx) stationary source emissions from an integrated iron and steel works as research object,to investigate NOx emissions in 2010,account NOx emissions and discharge coefficients of every production equipment in every production link.At the same time,combined with present NOx reduction control technologies at home and abroad and emission reduction potential of each plant,the applicable NOx reduction control measures and recommendations are presented,which can provide ideas and ways for iron and steel enterprises to further develop NOx emissions reduction during 12th Five-Year.
