摘　　要：文章论述了目前降低火电机组NO_x排放的主要技术,针对IGCC机组降低NO_x排放的蒸汽回注技术和加装SCR技术采用Aspend Plus建模和经济性核算的方法进行了对比研究,分别从机组初投资、运行成本以及社会环境效益方面进行探讨,指出蒸汽回注和加装SCR两种降低NO_x排放技术的优缺点。研究结果对IGCC及多联产机组在选择控制NO_x排放技术具有重要的工程价值和指导意义。This article discussed the NOx emission reduction technologies of thermal power unit. The technologies of the steam rejectionand selective catalytic reduction were studied by using Aspend Plus models and economic calculation methods. Get the advantages anddisadvantages of two technologies from initial cost and operational cost and environmental protection. engineering value and references for NOx emission reduction technology choice of IGCC and IGCC poly- generation.
