摘　　要：针对绥电公司2×800 MW超临界机组锅炉出现的低温再热器管路内壁腐蚀问题进行了详细介绍,分析了产生腐蚀的原因,并针对所采取的防腐蚀措施进行阐述,经验证所采取的防腐措施效果明显,能为电站锅炉防止低温再热器腐蚀提供借鉴。Inner wall corrosion problem of low temperature reheater for 2 × 800 MW supercritical boiler in Suizhong power plant is introduced, and the reasons of corrosion are analyzed. Treatment measures on corrosion pipeline and anti-eorrosion measures on corrosion reason are given. Praetiee shows that effect of anti-corrosion measures is obvious. The paper can provide good reference for corrosion prevention of low temperature reheater in power station boiler.
