摘　　要：NO_(X)排放浓度的控制是国家经济可持续发展和环境保护的客观要求。随着新环保法的实施,火力发电机组近零排放改造越来越成为主流,近零排放改造后,净烟气排放的NO_(X)限值由100mg/m^(3)降至50mg/m^(3),对脱硝出口NO_(X)的测量带来了新的影响。由此,本文对燃煤发电机组在线测量氮氧化物浓度偏差原因进行分析,提出了相应的措施,以减少氮氧化物对环境的不良影响。The control of NO_(X) emission concentration is the objective requirement of national economic sustainable development and environmental protection.With the implementation of the new environmental protection law,the near zero emission transformation of thermal power generating units has increasingly become the mainstream.After the near zero emission transformation,the NO_(X) limit of net flue gas emission has decreased from 100mg/m^(3)to 50mg/m^(3),which has a new impact on the measurement of NO_(X) at the denitration outlet.Therefore,this paper analyzes the reasons for the deviation of NO_(X) concentration measured on-line by coal-fired generator units,and puts forward corresponding measures to reduce the adverse impact of NO_(X) on the environment.
