摘要

针对万能达发电有限责任公司 2号炉低温再热器第Ⅴ组卧式蛇形管频繁爆管问题

通过试样分析

认为其主要由原支撑块结构不合理及焊接缺陷所致。结合大修

更换了位于高温区的管屏

并采取新的支撑块结构

使问题得以解决

Abstract

Directing against problem of frequent tubeburst for horizontal coil pipe in group NO.5 in lowtemperature reheater of boiler NO.2 of Wannengda PowerGeneration Co Ltd

it is believed through sample analysis that the main cause is due to unreasonable structure and welding defects of original support pads. Combined with major repair

the pipe panel situated in hightemperature area has been replaced

and new support pad structure being adopted

making the abovementioned problem to be solved.
