摘　　要：利用有限元分析方法对锅炉变负荷运行时汽包下降管接头处的三维温度场及应力场进行了计算分析，并对不同运行工况下的汽包壁的寿命损伤进行了估算，据此对ＨＧ６７０／１４０锅炉变负荷调峰提出合理化建议。The finite element method was used to calculate and analyze the three -- dimension temperature field and thermal stresses field of steam boiler drumin the area of downpipe and prediction of boiler drum life losses is made for different operation maaes according tO test data of load yaring operation in ShaogUan power Plant. SOme measures were Proposed for variable load operation.
