摘　　要：文章对广州瑞明电力股份有限公司1号锅炉采用深度空气分级技术(SOFA)降低NOx排放的可行性进行了分析,认为采用SOFA配合部分二次风偏转技术,可有效降低NOx排放水平。从燃烧器整体布局、燃烧系统配风、燃烧器各喷口设置、SOFA布置高度、各二次风偏转角度的选择几个方面介绍了改造方案的主要设计特点。The Paper analyzes the feasibility of adopting deep staging technology of firing air（SOFA）to reduce the NOx emission of NO. 1 boiler in Guangzhon Ruiming Power Corp. Ltd., holds that,to adopt SOFA with combination of part secondary air deflection technology,can effectively reduce NOx emission level.From the overaU arrangement of burners,air distribution of firing system,jet orifice set-up of bumers,height of SOFA arrangement,deflection angle selection of each secondary air etc. several aspects,the paper briefs the main design features of retrofitting scheme.
