摘要

华电红雁池发电有限责任公司670 t/h锅炉在试运行期间后竖井前包墙甲侧悬吊直管连续发生环型横向断裂或爆裂

分析认为其主要原因是甲侧悬吊管区域拘束应力异常偏大

以及新装锅炉鳍片端部焊接残余应力较大所致。对此

采取了消除应力等处理和预防措施

避免了事故的再次发生。

Abstract

The ring-type transverse breakage or burst crack has successively occurred in suspended piping system at A side on the front embracing wall in rear vertical shaft of the 670 t/h boiler of Hudian Hongyanchi Power Generation Co Ltd during trial operation.It is believed from analysis that the main cause is due to the restraint stress at A side of the suspended piping system being abnormally large

and the greater residual stress of welding newly installed finned tubes on the boiler.For this

preventive measures have been taken for stress-eliminating treatment

avoiding accidents to occur again.
