【 摘 要 】

The paper provides a comprehensive scheme for assessment of the residual service life and extension of operating life of steam turbine rotors with expired fleet service life. The residual service life of high temperature rotors for high & intermediate pressure cylinders of К-200-130-3 steam turbine without heat grooves calculated and it was showed that the residual service life of high & intermediate pressure rotors without grooves has been extended as compared to the К-200-130-1 turbine rotors with grooves. Also residual life management by supplying hot steam to the HPC and IPC seals was investigated and it was noted their significant impact on the residual service life.
