Design Kalina cycle for geothermal power plant and its turbine.
Luermann, Július ; Martinec, Jiří (referee) ; Škorpík, Jiří (advisor)
This master’s thesis analyses Kalina cycle, a power cycle where ammonia – water solution is used as a working fluid. The first part of this study introduces us to the Kalina cycle, presents its advantages and disadvantages, characteristics of the working fluid and its applications. Second section concerns with the method of cycle design and describes the calculation model made in this thesis. The calculation model is attached in a separate .XLSM file. The third part shows calculation of the cycle for given parameters, determination of cycle efficiency and main proportions of the thermal turbine. In the conclusion are the interpretations of the calculations results.

Steam turbine
Čípek, Petr ; Škorpík, Jiří (referee) ; Fiedler, Jan (advisor)
The aim of the thesis is to design a high-speed steam turbine as a small energy source. Steam turbine consists of a high-pressure, a medium-pressure and a low-pressure part with a removable condensing module. High-pressure part is designed to perform a single-stage radial turbine with axial steam outlet. The work also includes the layout of the modules and sections. To design individual parts are used steam table „X-steam“.

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

Technologies for use hydrogen from Energiepark Mainz
Florian, Tibor ; Šnajdárek, Ladislav (referee) ; Škorpík, Jiří (advisor)
The goal of this bachelor’s thesis is the description of hydrogen, its production methods, subsequent use and comparison by selected criteria. In the beginning of the thesis, hydrogen is described as an element. The following chapter briefly deals with its history in energy industry and the most commonly used production technologies. The emphasis is on a Power-to-Gas facility, Energiepark Mainz. In the end, hydrogen is compared as a fuel in the automotive industry.

Technical and economic proposal for wind power in the locality Břežany.
Růžička, Tomáš ; Chroboczek, Libor (referee) ; Škorpík, Jiří (advisor)
There is currently a construction project underway in the czech republic (Vesta V52) to build a large wind farm. Due to their size there is a lot of oposition to this venture. My project is a short history of using Wind Energy, the principle behind wind farms and detailed discriptions of Vesta V52 itself. You will also find a theoretical calculation of the produced electricity per year and considered cost and sustainability of the plant.

Aerodynamics of axial wind turbines
Just, Jan ; Pospíšil, Jiří (referee) ; Škorpík, Jiří (advisor)
This master thesis concerns about problematics of wind turbines. The document summarizes basic theory based on the law of momentum conservation which is essential tool for the design and calculation of wind turbines. The theory is complemented by number of correction factors and then used in the design of wind turbine for specific parameters. The calculation is performed iteratively using Matlab software and the actual code is given in appendix. Graphs summarizing the progress of various units along the blades are presented in the document. The final section briefly describes advanced topics of aerodynamics concerning other important factors that the field of wind energy deal with in recent time.

Type design and flowchart of a steam turbine for a specific location
Kalina, Leoš ; Pospíšil, Jiří (referee) ; Škorpík, Jiří (advisor)
This master's thesis is deals with type designing and implementing the steam turbine to the machine part of heat plant in reconstruction. The thesis consists of two parts. First part is theoretical explanation of the heating industry, steam turbines, thermal cycles and components of thermal power plants. Second part of the thesis describes the design and calculation of thermal diagrams based on turbine parameters, which were provided from Tenza, a.s. tender. There is a simplified calculation of technical-economic study in the conclusion of the thesis. The thesis output is recommendation of single final implementation solution for customer.

Biomass utilization for cogeneration small power
Neminář, Štěpán ; Škorpík, Jiří (referee) ; Baláš, Marek (advisor)
The subject of this thesis is the utilization of biomass for cogeneration units of small power (to 500 kWe). Within the first paragraphs the thesis focuses on technologies which produce more valuable fuels than the solid biomass. This chapter also describes the most recent processes of waste biomass usage. The following section summarizes gaseous and liquid products of this procedure and their feasible use in co-generation. In the last part of this thesis author describes a CHP devices which are used in small electric power production and assesses their advantages and disadvantages. Consequently, some options of their practical usage are highlighted. As a conclusion, these devices are compared and their possible future application is illustrated.
