Lifetime analysis of the steam generator of a solar tower plant

•A creep-fatigue analysis of the steam generator of a solar tower plant is performed.•An elastic-plastic approach is used to consider the material cyclic hardening.•Temperature rates up to 150 °C/h assure the 25 years lifetime of the steam generator.•The most critical point is the superheater head-n...
