超临界锅炉末级过热器和末级再热器的升级改造

摘要

分析超临界锅炉末级过热器、末级再热器升级改造原因，确定改造方案，介绍加工监造、入场验收项目及标准，对安装过程进行优化，改造后主汽温度、再热温度达到预期值，并消除了爆管隐患。%upgrade reason analysis of Supercritical Boiler final superheater, final reheater, determined the transformation plan, build, the ad-mission acceptance project and standard process supervision, the installation process was optimized, after the transformation of the main steam temperature, reheating temperature reaches the expected value, and remove the hidden dangers of tube explosion.
