把國內(nèi)近幾年濕煙囪排煙筒防腐設(shè)計(jì)的經(jīng)驗(yàn)結(jié)合到舊煙囪脫硫改造工程加以分析,提出燃煤發(fā)電廠舊煙囪脫硫改造應(yīng)考慮的主要因素,針對每一個(gè)舊煙囪實(shí)際狀況區(qū)別對待,選擇合適的防腐方案.通過華能陽邏電廠二期煙囪防腐改造工程實(shí)例,在國內(nèi)煙囪防腐改造材料性能分析的基礎(chǔ)上,建議幾種舊煙囪防腐改造方案的適用范圍,推薦了煙囪防腐改造工程實(shí)施的技術(shù)路線,對燃煤發(fā)電廠舊煙囪防腐改造有所參考.

　　為減少二氧化硫排放,國家發(fā)展和改革委員會(huì)3月29日公布了今年現(xiàn)有燃煤電廠需開工建設(shè)煙氣脫硫項(xiàng)目名單,總裝機(jī)容量為3 747.4萬kW.15家發(fā)電集團(tuán)、發(fā)電公司和26個(gè)獨(dú)立經(jīng)營發(fā)電廠(共計(jì)78個(gè)電廠)榜上有名.國家電網(wǎng)公司184萬kW燃煤機(jī)組需開工建設(shè)煙氣脫硫項(xiàng)目,華能集團(tuán)公司309.4萬kW,大唐集團(tuán)公司434萬kW,華電集團(tuán)公司96萬kW,國電集團(tuán)公司312萬kW,中國電力投資集團(tuán)公司303萬kW.而且這些煙氣脫硫項(xiàng)目的開工建設(shè),還會(huì)直接影響這些企業(yè)將來新建、擴(kuò)建項(xiàng)目的上報(bào)審批問題.對此,華能、大唐國際、華電、國電等發(fā)電集團(tuán)公司已經(jīng)開始對所屬舊機(jī)組煙囪… 
 
　By combining the experience in design of wet chimney anti-corrosion with the FGD reconstruction of the old chimney in China in recent years,the author puts forward the main considerations in FGD renovation of the old chimneys and suggests that the proper anti-corrosion options should be taken depending on the actual conditions of the old chimneys.An example of the anti-corrosion reconstruction on the chimney of Huaneng Yangluo Power Plant Phase II is given together with the performance analysis of anti-corrosive material.The applicable scope of some anti-corrosion reconstruction options on the old chimneys is suggested and the technical guideline to implementing such an anti-corrosion reconstruction project on chimneys is recommended,which can be referred to in the future for the similar projects of the fossil-fired power plants.
