STEAM TURBINE "NUOVO PIGNONE HNK 50/71", 23 MW

Listing description

Direct negotiation of a steam turbine from a major energy multinational located in Puertollano.

The manufacturer is Nuovo Pignone, and the model is HNK 50/71.

The steam turbine is designed as a single cylinder, of the non-overheating condensing type, which drives the generator rotor through a speed-reducing gear.

Assembly of the steam turbine was completed in 2002 and the units were never put into service. It has not received any maintenance since that date.

Further borescope inspection is pending to assess the internal condition of the high-pressure and intermediate-pressure side vanes and blades, rotor, and steam inlet areas. Once the inspection is completed, all the details and information obtained from the test will be uploaded as additional information to the batch (estimated date at the end of February).

Any additional information needed should be contact the Escrapalia staff.
