摘 要：随着我国经济、社会发展，国家降低能耗、节能减排政策的不断深入，火电机组不断向高参数、大容量方向发展，目前国内超临界、超超临界锅炉开始大量、集中建设和投运，从已投运机组的试运及投运后的运行情况来看，频繁爆管是困扰超、超超临界机组的一个主要问题，割管检查此项工作开展时间不长，经验不是很多，本文主要介绍电厂2×660MW超超临界机组在建设过程中割管检查的部位、检查方法，检查效果等进行介绍。

Abstract: As China's economic and social development, the state to reduce energy consumption, energy-saving emission reduction policies, continued to deepen，Thermal power unit to keep the high-parameter, large-capacity develop in the direction。Domestic supercritical, ultra supercritical boilers began to large, concentrated efforts to build and put into operation in，Generating units have been put into operation from the trial operation and put into operation after the operation point of view, frequently burst pipe is troubled super, ultra-supercritical unit in a major problem。Cutting tube inspections to carry out this work is not long, experience, not many。This paper describes xing chang Plant 2×660MW USC In the construction process the site of cutting tube inspections, inspection methods, inspection results, etc. are introduced
Key words: New Units; Boiler Explosion; Cutting tube inspections; Case Study
