    Abstract

    Structural analysis and lifetime assessment of steam drums in conventional power plants are discussed in this article. The analyses involve damage and structural mechanics, heat transfer analyses and fracture mechanics, and are connected to fluid mechanics. The used input data was from two steam drums in a Finnish fossil fuel power plant. Structural mechanics analyses were performed with FEM code ABAQUS. The lifetime analyses were performed using fracture mechanics analysis code VTTBESIT1.0. The primary considered damage mechanism was crack growth by corrosion-fatigue. Conclusions of the analysis results are summarised
