    • Conventional Servo System to Direct Drive Actuators Why Does It Matter? 

      Jain, Mayank; Nishiyama, Kenichi; Ikeno, Kyoichi (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      This paper discusses the development of Actuators over a period of time. The purpose of an Actuator (servo system) is to operate steam turbine control valves. With the increasing demand for better control of steam valves ...
    • Development of New Heat Treatment Method to Impart High Creep Strength and High Toughness to Rotor Material for Condensing Steam Turbine 

      Ikeno, Kyoichi; Jain, Mayank; Terada, Katsumi; Tsurusaki, Yuzo; Morioka, Shinya (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      Higher temperatures in the HP section of the condensing Turbine requires rotor with high creep strength while low temperatures in the LP section require the rotor to have high toughness. The design basis for current rotor ...
    • Investigation and Resolution of Governing Valve Linkage Failure for Compressor Drive Steam Turbine 

      Nishiyama, Kenichi; Jain, Mayank; Subramani, Elumalai (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      Fatigue failure of Governing Valve Linkage Rod end bearing and wear marks on several parts was observed on a extraction steam turbine (driving a centrifugal compressor) after it was in service for more than 9 year. The top ...

    • Investigation of unexpected Trips in Steam Turbine 

      Nishiyama, Kenichi; Jain, Mayank; Fuchiwaki, Shunsuke; Woon Lip, Teo (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      A 56 MW steam turbine tripped several times over a short period of time although the trip signal was not sent. A thorough examination of the turbine at site ruled out any problems with the trip system. The pressure data ...
    • Steam Turbine 101/201 Combined, Basic Knowledge of Steam Turbine 

      Walton, Matt; Alvarado, Fabiola; Jain, Mayank; Takemura, Daisuke; Tasaki, Akinori (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      It is shown as the outline in this short course that the role of steam turbine, history, classification, basic structure, components and their function, manufacturing and design process and control system. And also, the ...
