Research on Flexible Sludge Lancing Device for Steam Generator

摘要: 蒸汽发生器(SG)二次侧管板表面堆积的泥渣会随运行时间的增加而变硬,使传热管受到腐蚀和挤压,导致传热管破裂。为了直接对硬泥渣堆积层进行冲洗,研制了一种SG柔性泥渣冲洗枪。本文阐述了SG柔性泥渣冲洗枪的结构、原理、主要技术指标及技术难点。应用结果表明,研制的SG柔性泥渣冲洗枪满足SG柔性冲洗的要求,冲洗效果显著。

Abstract: The sludge deposited on the secondary side of stream generator（SG） tube sheet will become hard as the process of time,and it will degrade the tube.In order to lance the sludge directly and decrease the harm to the tube,a sort of SG sludge flexible lancing was researched.This paper describes the structure,principle,technology index and difficulty of the sludge flexible lancing.The application result shows that the lancing satisfies the flexible lancing requirement and ensures the cleanness of SG secondary side.
