Gas Turbine Frame V exciter side high vibration
  | Posted by Rohit Das  on 14 October, 2012 - 1:28 am |
GT (21 MW, Mixed fuel operation) is having high vibration in BB5 and BB6 in exciter end.
After combustion inspection, generator side vibrations were found to be very high. Vertical vibrations were less so the machine did not trip, however, horizontal vibrations were as high as 20 mm/sec. Can you please suggest reasons for the same?
