摘要

通过爆口宏观检查、几何尺寸测量、化学成分分析、拉伸性能试验、金相检验、能谱分析等对亚临界300MW机组锅炉水冷壁内螺纹管爆管原因进行了分析。结果表明

水冷壁爆管是由于氢损伤所致。

Abstract

Through macroscopic insepection of burst mouth

measurement of geometric size

analysis of chemical components

tensile strength test

metallographic examination

and energy spectrum analysis etc.

the causes leading to burst of rifled tubes on the water-wall in boilers for subcritical 300 MW unit have been tested and analysed.Results of test show that the tube-burst is due to hydrogen damage.
