摘　　要：钢铁行业是NOX污染减排的重点领域。在预测钢铁行业未来发展趋势的基础上,基于情景分析法,设置3个NOX排放情景,估算出2020年不同情景下钢铁行业NOX排放量及不同控制措施的减排贡献。研究结果表明,未来钢铁行业产品产量的快速上涨加大了NOX减排压力。在不实施额外NOX控制措施的情况下,2020年钢铁行业NOX排放量约为108万t,相比2013年上涨9%。实施钢铁行业NOX排放控制措施可取得显著的减排效果,根据两种控制情景预计NOX的减排比例分别为5%和13%。淘汰落后产能和烧结烟气循环技术是NOX减排的最有效手段。The iron and steel industry is an important field in NOXemission reduction.Based on prediction of future development trend of the iron and steel industry,three NOXemission reduction scenarios were designed,and then NOXemission and emission reduction contribution of different control measures in corresponding NOXemission scenarios in 2020 were estimated.As a result,it is indicated that a sharp rise in product output of steel industry will enhance the NOXemission reduction pressure.NOXemission will rise to 1.08 million ton,which means 9%increase comparing with that in 2013.Emission control measures get significant effect.According to control scenarios,NOXemission is expected to be reduced by 5%and 13%.Elimination of backward production capacity and flue gas recycling technology of sintering are effective control measures.
