摘要
某型号为KCTK35/40 100锅炉省煤器,在运行两年多时间内发生多次爆管事故。采用化学分析、金相检验及扫描电镜等分析方法对锅炉省煤器穿孔漏水原因进行了分析。结果表明,省煤器管内外壁共同腐蚀是引起其快速穿孔的原因,内壁产生了溶解氧腐蚀,外壁产生了氧化腐蚀及硫腐蚀。
In the operating period of two years, the type KCTK35/40-100 tubes of boiler economizer have been exploded many times. By means of chemical composition analysis, microstructure examination and scanning electron microscope, the reason of tube leak was analyzed. The results showed that the corrosion of inside and outside of the tubes caused to hole quickly, and the inside corroded by soluble oxygen and the outside corroded by oxygen and sulphur.
