【摘要】 基于能源消费计算得到2009年上海市NOx排放总量为571141t,其中燃煤电厂、机动车、黑色金属冶炼及压延加工企业排放量共占总排放量的65.1%.燃煤电厂通过采用LNB(低氮燃烧)技术和SCR(选择性氧化还原)技术,可削减总排放量的12.4%;钢铁企业的烧结机采用分步脱硫脱硝法、活性炭/焦法、循环流化床法等技术可削减3.7%～4.4%;高排放机动车改造基本不可行,建议加速和提前淘汰,可削减2.5%.费用效果分析表明,"十二五"期间完成燃煤电厂、烧结烟气脱硝和高污染机动车淘汰的减排费用效果比分别为4.7×104、7.9×104～10.6×104、12.4×104元/t.燃煤电厂脱硝改造费用效果比低、技术成熟,建议作为首要减排措施.更多还原

【Abstract】 Based on energy consumption,the total NOx emissions of Shanghai in 2009 were estimated to be 571,141 tons.The emissions from coal-burning power plants,motor vehicles,ferrous metal smelting and rolling processing enterprises accounted for 65.1% of the total emissions.About 12.4% of NOx emissions from coal-burning power plants could be reduced through application of low-nitrogen oxide combustion(LNB) and selective catalytic reduction(SCR) techniques.The integrated iron and steel enterprises could reduce 3.7%-4.4% of NOx emissions through application of the WFGD+SCR,PAFP-FGD,or CFB-FGD techniques to the sintering machines.Though accelerating the phase-out of high-emission vehicles,the NOx emissions could be reduced by 2.5%.Cost-benefit analysis of NOx emission reductions shows that the benefits of coal-burning power plant denitration,sintering flue gas denitrification and phase-out of high-pollution vehicles were 4.7×104,7.9×104-10.6×104 and 12.4×104 RMB/t,respectively,during the Twelfth Five-Year Plan period.Since the cost of coal-burning power plant denitrification is low,and the technique is already mature,it should be given priority among NOx emission reduction measures.更多还原
