梅钢4#转炉汽化冷却系统结垢分析及在线处置

Analysis and Online Treatment of Scaling in the Vaporization Cooling System of Meisteel No.4 Converter

介绍了梅钢4#余热锅炉系统结垢的原因,提出了在线处理方案。通过药剂控制将给水中带入锅炉的结垢物质与所加药剂进行反应,生成悬浮颗粒,呈分散状态的软渣;同时将部分已沉积在管道内结垢的物质剥离下来;结合水质情况,制定排污方式,通过定期排污排出系统。

This paper introduces the causes of fouling in the No.4 waste heat boiler system of Meisteel,and puts forward online treatment scheme.Through the control of chemi⁃cals,the scaling material brought into the boiler in the feed water reacts with added chemi⁃cals to form suspended particles and dispersed soft slag,at the same time,part of the scal⁃ing material deposited in the pipeline is stripped off.Based on the water quality,the sew⁃age discharge mode is formulated,and the system is discharged through regular sewage dis⁃charge.
