Laser tracker - real time thermal analysis
The 13 MW steam units were installed around 2003 and have never been able to operate at capacity. EthosEnergy properly aligned them using real time thermal analysis, allowing them to operate at peak efficiency.

The 13 MW steam turbine units were installed around 2003 and have never been able to operate at capacity. High vibration limited the generator output and caused the unit to trip or shutdown due to shaft misalignment. Several vendors including the OEM had attempted to improve the running condition of the units and in one case damage was caused resulting in a major overhaul of one of the turbine and generator sets.
(3) 13 MW steam turbines with vibration significantly limited the generator output. This was caused due to the turbine moving in an unpredictable direction during the start-up and generator loading procedure.
The unit would operate at full speed but as the generator output was increased vibrations due to shaft misalignment would increase and trip the unit.
The thermal growth of the turbine and align the shafts, was operated at a less than optimal (in some cases 50%) condition.
The units were properly aligned using real time thermal analysis allowing them to operate at peak efficiency. Not only was there a vast improvement in performance but the reliability also improved. This plant primarily provides steam to the University campus so the ability to start, regulate and shutdown the units without thermal issues is critical. Power generation is a secondary function of this facility but has a large impact on the amount of power purchased.
