摘要
大容量火电机组参加调峰运行势在必行，经常启停和变负荷运行使设备疲劳寿命损耗增加。从安全角度考虑，必须了解设备的低周疲劳损耗情况。通过采用简化计算方法估算汽包低周疲劳寿命，从而对大型机组调峰运行情况作初步预测。
Large scale power unit acting as regulating peak unit is necessary .Starting up/down and changing frequently will decrease the unit's fatigue life . It is necessary to know the fatigue of the lower frequency for the security .It can estimate the lower frequency fatigue life of boiler drum by simplifying calculation method.
