Single-stage steam turbine
Hrnčířová, Michaela ; Fiedler, Jan (referee) ; Novotný, Zdeněk (advisor)
This bachelor thesis deal with project for single-stage steam turbine specified to the steam reduction station combined thermal cycle. Involvement rotary reduction is elective, to was enough exploited steam power. For the specified parameters was proposed designed the acceptable conception of turbo-generator with a direct connection to an asynchronous generator. The most important part work is the thermodynamic calculation of the flow part whose aim is achieve maximum efficiency and operation of turbines. To increase in efficiency and on the basis engeged turns is considered using of bandage. Also is effected the choice of acceptable steam paddings.

Reneweblw energy source at Slovakia
Szegedi, Peter ; Borbély, Richard (referee) ; Fiedler, Jan (advisor)
The bachelor thesis is divided into five main issues. The first issue is dealing with history of exploitation of water as a power supply in Slovakia and is describing current situation of exploitation of watercourses. The next part of the thesis is describing a present condition of power industry in Slovakia, its future perspective and a possibility of deriving benefit from the most perspective renewable resources of energy. The essential issue handles with water power stations ant its description. The last capture is focused on small hydroelectric power stations and technic – economical evaluation of three concrete SHPS. The conclusion is attending to short overview of information obtained by writing the bachelor thesis and to author’s own estimation of development of renewable energy sources situation in Slovakia.

Upgrading the secondary circuit of the Dukovany NPP
Fialová, Michaela ; Fiedler, Jan (referee) ; Šen, Hugo (advisor)
With the ever increasing usage of electric power and decreasing supply of natural resources, there is a growing effort to effectivelly maximise current dispositions of resources. Utilising project reserves at already functioning Nuclear powerplants belongs to these projects. In this article I am going to describe this utilisation and overall modernisation of the Dukovany Nuclear powerplant.

Renewable energy sources in CR
Žaloudek, Martin ; Moskalík, Jiří (referee) ; Fiedler, Jan (advisor)
The thesis consists of the definition of biomass and its exploitation as a sustainable resource. It describes different types of biomass and their influence on the process of transformation to use for energy needs. It also introduces possibilities of electric energy and heat production out of this raw material, accompanied by an illustrating example of biomass as a suitable fuel. The end of the thesis evaluates the importance of biomass as an energy resource for the Czech Republic.

Fireplace inlay
Štelcl, Otakar ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
Bacheor´s work is divided into four main parts. First part deal with division of fireplace inlays according to material, construction of combustion chamber, combustion air, heat transmission and used grate. Second part deal with ČSN EN 13229. Majority part of work deal with problematic of measurement instruments, measurement section of combustion products and also with measurement of effectivity of fireplace inlay. Last part of Bacheor’s work speak about possibilities of optimalization effectivity in whole amount of power of fireplace inlay.

Cogeneration power plant
Ptáček, Martin ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
This bachelor thesis deals with heat and power supply of the family house, which uses natural gas.The first part reveals cogeneration technology in general, especially cogeneration unit based on gas-engine (internal combustion engine).In the second part, the thesis focuses on energy budget (power-balance sheet) issue. Finally, the third and fourth chapter, deal with particular calculation of usability of cogeneration unit in the small family house. Due to a small final financial difference and large investment costs, with such a low heat and power consumption, this technology is unsuitable for this type of usage.

Energy consumption food-factory
Hrubý, Vojtěch ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
Venting, ventilation, air-conditioning and heating serving to maintain given conditions, e.g. temperature, humidness and hygiene standards for the clean air of production and other areas bring various difficult processes provided by different complicated equipments and systems. Goal of this graduation theses is to describe these proceses and actual situation in heat energy supply in food factory conditions of Cutisin in Slavkov u Brna. The main benefit of this graduation these is the description of actual central heating solution, state evaluation and innovative suggestion for the lay-out solution of central boiler-room.

Single stage steam turbine
Girman, Peter ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
The thesis deals with design of single stage steam turbine. Applicable alternatives with appraisal and variant solving were developed on the basis of overheated steam parameters. Main thesis output is design of the most appropriate variant with real turbine’s dimension and the most fitted applicability and the best effectiveness.

Solar heating swimming-bath water
Lučko, Martin ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
In this bachelor´s work I engage in problems and concept of solar system for preparing heating swimming-bath water. For heating – up has been used a bivalent system complemented by electric heating inlet. The calculation has been intent on concept of collector area size and balance of energy systém.

Solar heating tap water
Kysel, Stanislav ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
Solar heating tap water In this bachelor´s work I engage in problems and concept of solar system for preparing warm supply water. For heating – up has been used a bivalent system complemented by electric heating inlet. The calculation has been intent on concept of collector area size and size of the supply bin.
