    • CST07 - Blade failure analysis for steam turbines used for driving centrifugal compressors 
      Nakamura, Yuki; Tsurusaki, Yuzo; Oishi, Yusuke; Fujimura, Norihito; Sasaki, Yuichi; Hara, Akihiro (Turbomachinery Laboratory; Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, [2019])
      Blade failure was caused by a huge alkaline element of Na flowing into the steam turbine from upstream due to improper water treatment. In this presentation, we will inform the reason why Na precipitated in dry steam ...
    • CST08 - RCA report on governing valve seat failure for ERC Turbine 
      Nishiyama, Kenichi; Jain, Rishav; Oishi, Yusuke (Turbomachinery Laboratory; Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, [2019])
      Precise and stable steam flow control to the Turbine directly relates to improved steam turbine speed and load control and reduced system mechanical wear. This paper presents a complete failure of a Governing valve seat ...
    • Troubleshooting of Start Up for Old Steam Turbine 
      Singh, Ayush; Nogami, Tomoaki; Oishi, Yusuke; Koda, Takuro (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)
      During the start-up of an old steam turbine (about 30 years old), that was internally revamped, it was tripped due to high rotor vibrations. Site investigation was done to find out the root cause. Abnormal casing deformation ...
