Piston steam engine
Potměšil, Tomáš ; Fiedler, Jan (referee) ; Novotný, Zdeněk (advisor)
The thesis is concerned with posibility of using piston steam engine in minor local steam boiler plants and steam reduction stations. Shortly describes a history of steam engines, analyses and explains positives and negatives of different control gear conceptions and then a 3D model of selected conception is formed. Mainly there is implemented a thermodynamic proposal of steam engine for defined parameters of mechanical power 25 kW, frequency 1500 rpm, input steam pressure 1,5 MPa. Main dimensions of engine parts are determined. Lastly the work compares differences between piston steam engine and single-stage steam turbine and in principle reasons advantages of steam engine in reduction station.

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.

Meter run for servo-actuator test
Hřebíček, Martin ; Bogdálek, Jan (referee) ; Novotný, Zdeněk (advisor)
The aim of this bachelor´s thesis is projecting a metering and regulating run for servo-actuator test, choosing a suitable choice of the soft and accurate regulation of pulsing oil and projecting a suitable armature for holding an constant pressure of an overflow oil. Further to project a suitable kind of pump for supply of operative oil. To verify by calculation of an fitness of a choice of a given armature and choose these elements, which are accessible on Czech market. A projecting of a suitable machine for a detection of lifting of a spindle and a pressure of an impulsive oil to be able to analyze a results and electronically note on a PC output. To draw up a description of process soft measuring and correction of a given servo-actuator.

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.
