Abstract
The 1 000MW boiler water separator is chosen as the research object and its 3-D finite element model is founded based on the unit operation curve.The transient thermal stress,mechanical stress and total stress of the water separator are calculated by finite element method.The distributions law of the transient thermal stress,mechanical stress and total stress are discussed.The stress influence factors are analysed.The biggest stress location of the water separator and the variation law with time are finded out.
