Retrofit Steam Condensing Turbine
Holečková, Michaela ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
The aim of this master thesis is the retrofit of a condensing steam turbine. The thesis obtains a revision of the steam turbine, the reconstruction of steam turbine blades and the basic calculation of bolt torques of the turbine split plane. The master thesis is assigned to a specific retrofit of the steam turbine Lang. In the introductory part the thesis is focused on the turbine description and the basic functions of selected turbine components. The following part deals with the revision and the proposal of repairs for all components and the recommendation of additional modernizations of specific measuring equipments. The analysis of anchoring the stator and rotor blading and their reconstruction is discussed in the next part. In the last part the thesis focuses on the sealing of the turbine split plane and the calculation of the various bolt torques closely linked to the sealing.

Processing Czech in Python
Novotný, Zdeněk ; Schmidt, Marek (referee) ; Smrž, Pavel (advisor)
This bachorelor´s thesis presents some ways of Czech language processing. The first part contains a general destription of NLTK system. Some of aftermentioned functions were inspired by NLTK functions. There are described functions which attend to inflection and inflexion of various words class in Czech language. Next part is focused on processing of the text in Czech language in which are found and marked each sentences and other parts. Last part describes possibillity of tranformations rules application for each part of text. Results after rules application could be represented graphically.

Retrofit Backpressure Steam Turbine
Hlavinka, Miloslav ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
Tématem diplomové práce je revize parní turbíny Mitsubishi a výpočet utahovacích momentů šroubů dělící roviny. Tato práce je rozdělena do několika částí. Úvodní část práce obsahuje seznámení s rozsahem prováděných servisních prací na parních turbínách. Poté je zde samotná revize parní turbíny Mitsubishi. Tato revize je dělena podle jednotlivých komponent turbíny. Poté je zde stanoven seznam nutných oprav a také seznam doporučených oprav pro příští odstávku. V další části je zde shrnut výpočet utěsnění dělicích rovin a to s nebo bez odlehčení. Dále jsou rozebrány nejčastěji používané typy závitů spojovacího materiálu parních turbín. Hlavní částí práce je samotný výpočet utahovacího momentu. Výstupem této práce je poté program pro výpočet utahovacího momentu v programu Excel.

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.

Steam turbine
Sedlák, Pavel ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
The diploma thesis concentrates on a project of condensing steam turbine with uncontrolled extraction. These topics are analyzed in more detail: design of thermal diagram, thermodynamic calculation and turbine design concepts. First two topics are solved in the calculation section of the thesis. In the construction part are processed a third topic.

Backpressure Steam Turbine
Chrástek, Pavel ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
The diploma works demonstrates the thermodynamic calculation and design of the geometry flow profile of the back-pressure steam turbine for specified inlet and outlet conditions of steam. Next target of the work is to design the drawing of the turbine axial cross section. Structuring of this diploma work calculation is following: - regulating stage thermodynamic calculation - turbine stages calculation - equalizing-balancing piston calculation - entire turbine intrinsic efficiency and power rating determination - basic calculation of gearbox parameters and RENK-type gearbox selection for turbine and generator arrangement

Turbocharger
Růsek, Lukáš ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
A masters thesis deals with the question of deisel engine boosting by rotary turbochargers. The objective of the thesis is to propose suitable turbocharger´s concept for defined diesel combustion engine with power of 430 [kW]. The air boosting pressure is controlled by exhaust gas flow through the turbine and different EGR regimes, which are considered in the basic and corrected calculations. The final turbocharger´s concept is proposed to satisfy the defined technical requirements. Next technical recommendations are briefly summarized in the thesis conclusion for following turbocharger´s concept application.
