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.

Revision of steam turbines and repair design
Grepl, Martin ; Trněný, Bohumil (referee) ; Fiedler, Jan (advisor)
The theme of this master thesis is the revision and repair design of the condensing steam turbine SST 600 in Bielsko-Biala. The thesis deals with the revision of the steam turbine and the repair design of the damaged parts, the overall analysis of the separation of the steam of the split plane and the calculation of the parameters for tightening the new screws. The master thesis is given for a specific case. The introductory part of the master thesis deals with a basic description of the repaired steam turbine. Subsequently, a review of individual disassembled parts is given and the scope of the repairs is stated. In the next part of this thesis are summarized the causes of the steam leakage of the dividing plane at the points of the cross section and in the area of the control stage. The last part deals with the sealing problem of the split plane and the related main part of the master thesis is the calculation of the tightening parameters of bolts in the turbine housing. Another aim of the master thesis is to create drawings of the lightening of the split plane on turbine house.
