浅谈锅炉环保设备利用及改造

Discussion on utilization and retrofit of the boiler environmental protection equipments

目前我国电力行业新机组不断投入运行,许多机组加装环保设备的改造步伐也在不断加快。为借鉴新上机组烟气脱硝工程经验,针对邹县电厂三期600MW机组锅炉脱硫系统改造的经验和四期1 000MW机组锅炉脱硫系统同步投产后存在的问题,结合近年来电除尘器发生的事故以及脱硫工程改造中发生的问题,探讨了锅炉环保设备利用及设备改造的成功与不足,意在提醒环保设备的改造与利用中应注意的问题,提出了脱硫、脱硝设备的统筹规划方案,以避免重复建设投资。

At the present time quite a lot of new units put into operation unceasingly and many older units need to build environmental protection equipments in ore＂ counhy. According to the Retrofit experience of the desulphurization system of 600 MW unit in the third stage project and the operation problems of 1 000 MW unit in the forth stage as well as the accident occurred in the electric precipitator in recent years at Zouxian Power Plant, this paper discussed their advantages and disadvantages, and presented the overall plan scheme about flue gas desulphurization and denitrifieation in order to avoid investment with repetition.
