摘　　要：详细描述了新型烟气再循环技术改造方案,并以两个典型750 t/d生活垃圾焚烧炉烟气再循环改造实例为依托,分析新型烟气再循环方案在应用中的具体表现。新型烟气再循环技术改造方案与常规方案相比,具有避免管道腐蚀、延长设备使用寿命以及降低一氧化碳波动的优点。分析数据得出:河南省某项目氨水耗量节省14%~31%;江苏省某项目最多可以降低尿素单耗41%。通过核算额定负荷运行成本,新型再循环最多可节省年运行成本78.1万元。A detailed description of the new flue gas recirculation technology renovation plan was provided,and based on two typical 750 t/d municipal solid waste incinerator flue gas recirculation renovation examples,the specific performance of the new flue gas recirculation plan in application was analyzed.Compared with conventional solutions,the new flue gas recirculation technology renovation plan has the advantages of avoiding pipeline corrosion,extending equipment service life,and reducing carbon monoxide fluctuations.Analysis of data shows that a project in Henan province has saved 14% to 31% in ammonia water consumption;a project in Jiangsu province can reduce urea consumption by up to 41%.By calculating the operating cost at rated load,the new recycling system can save up to 781 000 yuan in annual operating costs.
