This backpressure turbine is from the beginning built 1955 by Stal Laval/ Asea and totaly rebuilt 2001 for a cost: aprox 2,2 milj. €. Everything inside the turbine and generator is totaly rebuilt. Running time from 2001: aprox 25.000 hours. Magnetism equipm. and vibration equip. new 1996. The plant was taken out of operation autumn 2006.

Reconstruction of turbine:

¤ A set of rotating parts of the inner turbine consisting of:

¤ Turbine discs with vane rings and shafts

¤ Rotating labyrinth and fixed plates

¤ Complete shaft seals of Flex-o-seal-type

¤ Necessary parts for sealing and locking

Rewinding of generator:

¤ Rewinding of two stators

¤ Rewinding of two rotors

New modified brush bridges to the respective rotor

Engine for control of rpm

Valves for drain to the intermediate pressure
