摘要
针对某600MW机组高温再热器爆管事故进行了原因分析,由于减温器进汽端套筒定位销钉脱落堵塞高再管子,而导致管子通流不畅造成爆管的主要原因。
By the analysis on the rupture of high-temperature reheater tube,it can be obtained that the locating pins of inlet side sleeve on the desuperheater pull out,which causes the cra mmingof high-temperature reheater tube.The rupture occurs when the steam in hightemperature reheater tube is unfree-flowing.
