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 ...

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 ...

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 ...
