AUXILIARY GEAR UNITS
Auxiliary gear units combine all ancillary units that are needed to operate a turbine.
Auxiliary gear units are mostly driven from the free shaft end of a gas turbine and enable a number of starting speeds to be achieved over a number of stages to power the following auxiliary drives:
- Water pumps
- Oil pumps (low- or high-pressure)
- Gas compressors
- Turning gear
- Starter motors
