Energy Assessment of Cogeneration and a Gas Boiler room
Kandl, Petr ; Počinková, Marcela (referee) ; Horák, Petr (advisor)
The thesis contains a gas boiler room energy assessment in Lišov. In the mentioned boiler room, there are instaled gas condensing boilers and cogeneration units Theoretical part of the thesis lists a summary of generally used cogeneration equipment and ordinarily used gases. Calculation part includes four variants of the boiler room reconstruction. Energy assessment compares the chosen variant from the calculation part with the original condition of the boiler room.

Influence of heating water temperature on efficiency of heating system
Hliboký, Samuel ; Poláčik, Ján (referee) ; Pospíšil, Jiří (advisor)
The content of this bachelor thesis is to describe ways of increasing efficiency of heating in a family house. Thesis is divided into theoretical and practical part. The theoretical part is dealing with principle of function of gas boilers and ways of decreasing the temperature of water in heating system. The practical part of thesis includes economic-technical evaluation of replacement of standard gas boiler by condensing boiler, based on return of investment.

Steam boiler for natural gas
Křivánek, Robin ; Kohout, Přemysl (referee) ; Skála, Zdeněk (advisor)
This diploma thesis describes the design of steam boiler for combustion natural gas, which has a steam power 80t/hour. In the first phase is performed calculation of stoichiometric amount of combustion air and flue gas. After that follows constructional proposal of the combustion chamber. Furthermore continue by calculation heating surfaces of the boiler. In conclusion, the thesis is focused on designing the injections. To check the accuracy of the results is recalculated heat balance the whole boiler.

Optimation and Innovation of Family Houses Heating
Dubnický, Ladislav ; Špiláček, Michal (referee) ; Lisý, Martin (advisor)
The aim of this bachelor thesis is to make a summary of knowledge of today´s modern heating systems for family houses. Each types of systems are compared to each other from economic, operating and ecologic point of view. At the end of the thesis there is a model conversion of energetic costs for specific family house and projection of new heating system.

Fossil fuels use in Czech Republic
Trávníček, Tomáš ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
The aim of the bachelor thesis is to collect facts about fossil fuels and their utilization in the Czech Republic. Firstly, the thesis discusses the fossil fuels and their division in general. The main part of the thesis is focused on mining and utilization of different kinds of fossil fuels in the Czech Republic with the emphasis being put on the brown coal, black coal and the natural gas. The oil and the lignite are briefly dealt with as well. The thesis includes the statistics of the fossil fuels‘ production of the mining companies, the summary of the big energy facilities in the Czech Republic and the mapping of their fuel bases.

Sector coupling and the future form of the electricity and gas sectors
Švéda, Miroslav ; MA, Martin Šik, (referee) ; Radil, Lukáš (advisor)
This thesis deals with Sector coupling problematics. First, it deals with the development and present situation in the generation and consumption of electric power and the development and present situation in the extraction and consumption of natural gas in the Czech Republic and in the European union. Further, the thesis deals with Sector coupling, this concept is explained, and it is adumbrated what questions it deals with. Then, the technologies that can be achieved in the future of Sector coupling are introduced. Pilot projects of these technologies are presented as part of the discussion about these technologies. Finally, a consideration of the future use of Sector coupling technologies in the Czech Republic is given.

Heigh effective condensation boiler feeded by natural gas
Renfus, Jaromír ; Fortelný, Zdeněk (referee) ; Fiedler, Jan (referee) ; Pospíšil, Jiří (advisor)
The dissertation is concerned with a problem of condensing boilers. The attention will apply to the condensing boiler which is filled in an absortion springle for a better an-nealing of exhaust gas. On this account the dissertation is possible to divide by some parts. There is a generally resolution of a condensing boiler´s principle and an effective annealing of exhaust gas for low temperatures in the first part. A description of an ab-sorption circulation follows in the second part. A practical part solves a suggestion of the condensing boiler with an absorption afterheat removal springle, an assesment of working parameters and a calculation of heat transfer surfaces. A technoeconomic ana-lysis of a proposed arrangement is made in the final part.

Underground Gas Storages
Flodr, Jan ; Škorpík, Jiří (referee) ; Lisý, Martin (advisor)
Natural gas is one of the main energy resources in the world. In case of countries without their own resources, it is very important how and where from they import this raw material and whether they utilize it effectively. The aim of this thesis is to describe the supply of the Czech Republic concerning natural gas and underground gas storage.
