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.

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.

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.

Piston steam engine
Hrbáček, Jaroslav ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
Object of this document is possibility of using piston steam engine (later only SE) in steam boiler plant, heating plant and steam reduction station. There is implemented a thermodynamic suggestion of SE for defined parameters of mechanical power 20 kW, frequency 1500 cpm, input steam pressure 1,5 MPa and warmth inside steam condenser 105 °C. There are implemented the main construction segments of SE with a view to steam distribution system. For determine a shape of work diagram SE (p-V diagram), there was created a supportive programme in Excel. The programme serves as the basis of determination of motor stroke volume and basis of determination of main dimensions.
