Thermal elongations in steam turbines with welded rotors made of advanced materials at supercritical steam parameters

Kosman Wojciech , Roskosz Maciej , Nawrat Krzysztof

This paper presents research results obtained for supercritical steam turbines. The analysis aims to develop data, knowledge bases and procedures to support the operational control of these turbines. The control involves thermal and strength states of the main components. The thermal states and axial elongation in turbine rotors and casings are modeled, and the results are analyzed. The components under investigation are made of more than one material.
