Analysis of the condition of the K 220-44 steam turbine drainage pipeline and proposal of corrective measures
Horký, Jiljí ; Milčák, Pavel (referee) ; Šnajdárek, Ladislav (advisor)
This diploma thesis deals with the analysis of the drainage pipeline of the Škoda K 220-44 steam turbine. This turbine is operated in Dukovany Nuclear Power Plant. One part of this work is proposal of corrective measures. The aims of this work include the creation of a search for drainage, steam, erosion corrosion and mapping of defects in long-term operated drainage system. Work also includes the evaluation of measured values of the pipe wall thickness measured by ultrasonic analyzer. In addition, the work contains images created from 3D model, on which the location of defects and measurements are displayed.

Characteristic properties of axial stages of working machines
Hejduk, Michal ; Šnajdárek, Ladislav (referee) ; Škorpík, Jiří (advisor)
This bachelor work is dealing with conclusion of basic characteristic of axial stages working machines. First part of this thesis presents the characteristics of principle behind every turbomachinery therefore not only the working machine but turbine as well. In the end of the first part the basic equations, which may be needed in the construction of such machines. Second part focuses on characteristic features, which are the same or very similar throughout axial turbomachinery. The last part of this thesis works with usage of different work machines in the industry. It is also mentioned here why are the axial turbomachinery work machines used instead of radial or tangential work machines

Impactor for fine particle collection
Paulíková, Kateřina ; Šnajdárek, Ladislav (referee) ; Pospíšil, Jiří (advisor)
This master thesis provides an overview of fine particles contained in the air and possibilities for their analysis, measurement and capture. In the beginning, the fine particle's size and origin is described. Then, the influence of fine particles on human health is stated. Next, methods of air analysis and fine particle's measurement are presented. Legislation for emissions and immissions in the Czech Republic is summarized. Finally the selected types of impactors are introduced. The practical part consists of three chapters. First chapter contains the fundamental calculation procedure and its subsequent refinement. In the following part the comparison of the calculation procedure with the parameters of the commercial impactor is provided. Lastly, the design of the impactor is created for the specified parameters using the developed calculation procedure.

Design of aeroderivative for use in compression stations
Dominik, Dávid ; Šnajdárek, Ladislav (referee) ; Škorpík, Jiří (advisor)
This thesis is concerned with the calculation of the power turbine. This turbine should be used in the automatic drive of the compressor used for compression of natural gas in compressor stations. Flight engine aeroderivate from the Rolls-Roye company, type RB211-22B, was used as gas generator. The main aim of the thesis is to summarize of the base atributes of the combustion turbines and aeroderivates. They are used for automatic engine, application a thermodynamic calculation of the power turbine, for reaction stage and basic strength calculations.

Cogeneration
Martinek, Jan ; Šnajdárek, Ladislav (referee) ; Fortelný, Zdeněk (advisor)
This bachelor thesis is intended to handle the issue of cogeneration. There is presented the principle of cogeneration and its benefits. Cogeneration is compared to the separate production of power and heat. This work deals with the storage of electric energy and heat and also deals with used batteries. The next chapter discusses the impact of cogeneration to environment and at the end there are mentioned the main Brno’s cogeneration units and central heat distribution in Brno.
