ANALYSIS OF TUBEBURST IN SUPERHEATER MADE FROM SA 213T91 STEEL
Sudden burst of one tube in platon superheater of boiler No.3 at Huaneng Fuzhou Power Plant occurred after continuous operation of 74356h. Through macrostructure visual inspection
metallographic analysis
mechanical property test
and inspection after cuttingoff access hole of the bursted tube's inlet header
it is determined that the tubeburst was due to blockage of the said tube inlet by foreign matters
making the said tube to be overheated in a very short time.
