      基于CFB-FGD技术的烟气超低排放工程性能测试评估

      Testing and Assessment on Performance of Flue Gas Ultra Low Emission Based on CFB-FGD Technology

      摘要:
      以基于烟气循环流化床脱硫除尘技术的中国中部地区某新建350 MW循环流化床机组超低排放工程为研究对象,对100%和75%负荷工况下SO2、颗粒物等常规污染物和PM2.5、SO3、汞等非常规污染物的浓度进行现场检测3评估CFB锅炉炉内脱硫+炉外CFB-FGD脱硫除尘技术实现SO2和颗粒物超低排放的达标能力. 现场监测及评估结果表明,该技术组合能实现SO2小于35 mg/m3和颗粒物小于10 mg/m3的超低排放要求,对SO3、汞等非常规污染物具有一定的协同脱除作用.
      Abstract:
      Taking the CFB-FGD-based ultra low emission project of a newly built 350-MW CFB unit in central China as a study case,the concentrations of conventional pollutants (e.g.SO2,dust,etc.) and non-conventional pollutants (e.g.PM2.5 particles,SO3 and mercury,etc.) are tested on the field with 100% loading and 75% loading conditions respectively to evaluate the capabilities of ultra low SO2 and dust emission by CFB furnace desulphurization +CFB-FGD sulfur and dust removal technologies.The field monitoring and evaluation results show that the combination of these technologies can not only satisfy the requirements of ultra low emission with SO2 concentrations of less than 35 mg/m3 and dust concentrations of less than 10 mg/m3,but also has synergistic removal effects on SO3,mercury and some other non-conventional pollutants.
