摘 要：隨著我國經(jīng)濟(jì)、社會發(fā)展，國家降低能耗、節(jié)能減排政策的不斷深入，火電機(jī)組不斷向高參數(shù)、大容量方向發(fā)展，目前國內(nèi)超臨界、超超臨界鍋爐開始大量、集中建設(shè)和投運(yùn)，從已投運(yùn)機(jī)組的試運(yùn)及投運(yùn)后的運(yùn)行情況來看，頻繁爆管是困擾超、超超臨界機(jī)組的一個主要問題，割管檢查此項(xiàng)工作開展時間不長，經(jīng)驗(yàn)不是很多，本文主要介紹電廠2×660MW超超臨界機(jī)組在建設(shè)過程中割管檢查的部位、檢查方法，檢查效果等進(jìn)行介紹。

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
