直流锅炉给水加氧处理技术的应用

The Application of Feedwater Oxygenated Treatment on the Once-through Boiler

介绍了江苏常熟发电有限公司1、2号机组直流锅炉给水加氧处理后热力系统水汽品质和锅炉水冷壁的保护膜和沉积速率测定结果。结果表明:水汽系统含铁量大幅度降低,精处理运行周期延长,锅炉水冷壁沉积速率明显降低,并形成以Fe2O3为主的致密保护膜。

The analysis result of the quality of water vapor and the protection membrane and the deposit rate after feedwater oxygenated treatment on the No. 1 ,No.2 unit ofchangshu power generation company are introduced. The result indicate that the iron in the water vapor reduced great;the run period of the condensate polishing system was prolonged;the deposit rate of the water-wall tube was decreased evidently and the main component of compact protection membrane is Fe2O3 on the water-wall tube surface.
