We are having 15 MW back pressure steam turbine bagasse co generation power plant. we have recently carried out commissioning and balancing of our turbine and the corresponding coupling with the gear box. We are maintaining the lube oil temperature as per the limits but even then we are experiencing the serious problem of high vibration at HP and LP side bearing of the turbine, please suggest if you have any.....

check for turbine and bearing phase angle it must be 180,
And, i suspect that there may be rub have check on that as well. Also, monitor the vibration and let me know.
