| Abstract: | The failure of too large temperature difference between upper and lower wall of turbine cylinder during start/stop period of the turbine was analyzed,which was found to be caused by imperfect structure of the drainage system,for which retrofit scheme and manipulation suggestions were proposed.Actual temperature difference between the upper and lower wall is now below 40 K during start up period after retrofit,resulting in safety operation of the turbine. |
