Steam Turbine Revision
Potměšil, Tomáš ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
This work deals with current application of the developing field of post-warranty service of old turbines in the energy sector. There are described various types of repairs following the recommendations of commonly performed actions. Revision finding is focused on back-pressure steam turbine marked R12-9 / 2, which was scheduled for overhaul after 180 000 operating hours. Revision findings include a detailed description of the turbine and method of repair. It is also performed calculating the losses in the axial blade stage of cascade by AMDC-KO methodology on because of the choice type of blading and then comparing by technical justification for the choice of one of the variants for the customer.
