低氮改造完成後，鍋爐的運行維護工作相較於改造前需要更加精細和係統化，這是因為低氮技術的引入往往伴隨著燃燒方式、設she備bei結jie構gou和he控kong製zhi邏luo輯ji的de變bian化hua，若ruo維wei護hu不bu當dang，不bu僅jin可ke能neng影ying響xiang鍋guo爐lu的de運yun行xing效xiao率lv，還hai可ke能neng導dao致zhi氮dan氧yang化hua物wu排pai放fang超chao標biao，甚shen至zhi縮suo短duan設she備bei使shi用yong壽shou命ming。首shou先xian，在zai燃ran燒shao係xi統tong的de維wei護hu方fang麵mian，低di氮dan改gai造zao通tong常chang涉she及ji燃ran燒shao器qi的de更geng換huan或huo升sheng級ji，這zhe類lei新xin型xing燃ran燒shao器qi對dui燃ran氣qi壓ya力li、空氣配比等參數的要求更為嚴格，因此需要定期檢查燃燒器的工作狀態，確保噴嘴無堵塞、點火係統靈敏可靠，同時還要定期校準燃氣閥組和空氣調節裝置，以保證燃燒過程的穩定性和高效性。
煙氣再循環係統是許多低氮改造zhongchangyongdejishushouduan，qiyunxingzhuangtaizhijieyingxiangdanyanghuawudekongzhixiaoguo。zaiweihuguochengzhong，xuyaozhongdianguanzhuzaixunhuanfengjideyunxingqingkuang，jianzhafengjizhouchengshifourunhualianghao、葉ye片pian是shi否fou積ji灰hui或huo腐fu蝕shi，同tong時shi還hai要yao監jian測ce再zai循xun環huan煙yan氣qi的de流liu量liang和he溫wen度du，確que保bao其qi在zai設she計ji範fan圍wei內nei波bo動dong。此ci外wai，再zai循xun環huan煙yan道dao和he換huan熱re器qi表biao麵mian容rong易yi積ji灰hui，長chang期qi運yun行xing可ke能neng導dao致zhi傳chuan熱re效xiao率lv下xia降jiang和he係xi統tong阻zu力li增zeng加jia，因yin此ci需xu要yao定ding期qi清qing理li煙yan道dao和he換huan熱re器qi，保bao持chi煙yan氣qi流liu通tong順shun暢chang。
對於采用選擇性催化還原（SCR）或選擇性非催化還原（SNCR）等末端脫硝技術的鍋爐，催化劑或還原劑的維護管理尤為重要。SCR係統中的催化劑在使用過程中會因中毒、dusaihuomosunershixiao，yincixuyaodingqijiancecuihuajidehuoxing，binggenjushijiqingkuangjishigenghuanhuozaisheng。tongshi，anshuihuoniaosudenghaiyuanjidechucunhetoujiaxitongyexuyaodingqijianzha，quebaobeng、閥門和噴槍等設備無泄漏、無堵塞，還原劑的濃度和流量符合設計要求。對於SNCR係統，還需要優化還原劑的噴射位置和角度，以提高脫硝效率，避免氨逃逸對後續設備造成腐蝕。
