摘要
通过对2023t/h锅炉后屏过热器泄漏的异种钢焊接接头分析,阐述了2种钢材的可焊性、焊接缺陷对使用寿命影响以及锅炉自身的结构和炉内的空气动力场对受热面的影响等因素,并提出了10项相应的预防措施。
Starting occurred to a 2 023 t/h defects, on service life, surfaces are elucidated. with analyzing leakages, occurring at weld joints between tubes of different types of steel, that boilers＇ platen superheater, the effect, of weldability of 2 different types of steel and welding as well as the influence, of the boiler＇s structure and flow field in the furnace, on the heat delivery Ten relevant measures of prevention are moreover mentioned.
