本文为汽轮机涡轮机转子的剩余寿命评估和延长使用寿命提供了一个综合方案。对无热槽的涡轮机高中压缸高温转子的剩余寿命进行了计算，结果表明，与有热槽的涡轮机高中压缸转子相比，无热槽的高中压缸高温转子的剩余寿命有所延长。还研究了通过向HPC和IPC密封提供热蒸汽进行的剩余寿命管理，并注意到其对剩余使用寿命的显著影响。
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.
