摘　　要：对燃煤蒸汽锅炉烟气脱硫脱硝采用低氮燃烧技术(ROFA)结合选择性非催化还原(Rotamix)和选择性催化还原(SNCR+SCR)的联合脱硝工艺进行改造,使烟气排放达到氮氧化物含量不超过100 mg/m3。The modification on coal-fired steam boiler flue gas desulphurization and denitrification was carried out by combining low nitrogen combustion technology （ROFA） （Rotating Opposed Fire Air） plus selected non-catalystic reduction （Rotamix） plus selected catalystic reduction （SNCR ＋ SCR）. The content of released nitrogen oxide didn＇t exceed 100 mg/m3, which is stipulated in GB 13223--2011 Thermal Power Plant Air-Pollutant Emission Standards, released in 2011 by Ministry of Environmental Protection.
