UTILIZATION OF BIOGAS IN TRANSPORT
Štylárek, Milan ; Zháňal, Lubor (referee) ; Vopařil, Jan (advisor)
Objective of this bachelor thesis is evaluating the possibility of utilization of biogas as an alternative fuel for combustion engines in traffic. Production and distribution of upgraded biogas is described as well as situation of its utilization in the world. This is followed by a comparison of situation in biomethan utilization in Czech republic and Sweden. There are explained barriers to commercial placing and its possible eliminating. In the end the model study of replacement of farm vehicle fleet for CNG vehicles is described.

Gas steam boiler design
Vacek, Jiří ; Bursa, Robert (referee) ; Skála, Zdeněk (advisor)
The aim of this thesis is a draft of a gas steam boiler with steam output of 200 t/h. The first part of the paper provides stoichiometric calculations, then there are calculations of the dew point, boiler efficiency and the amount of gas. After that, calculations and a draft of the combustion chamber are carried out and then heat balances are drafted. In the following text, geometric properties of individual heat exchanging surfaces are drafted. At the end, there are control calculations. This thesis contains a blueprint of the gas steam boiler.

Natural gas
Trávníček, Zdeněk ; Moskalík, Jiří (referee) ; Pospíšil, Jiří (advisor)
The aim of the bachelor thesis is to collect facts about natural gas, focusing mainly on the situation in the Czech Republic. Firstly, the thesis discusses the natural gas in general - its properties, world resources, ways of production and usage. The main part of the thesis deals with supply and accumulation of natural gas in the Czech Republic. Secondly, enumeration and brief description of possibilities of natural gas substitution is presented. Finally, comparison of usage of classic non-condensing and condensing boiler for a family house heating is introduced. Recommendation of boiler type based on the model example is included as well.

Hotwater boiler for natural gas,60 MW, 1,6 MPa, 150/70°C
Gardavský, Jan ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
The aim of this thesis is design a hotwater boiler for burning natural gas with an output of 60 MW. Boiler works with temperature difference 150 °C / 70 °C. For a given fuel is calculated stoichiometric calculation. The following is the calculation of the heat balance of the boiler including the determinativ of thermal efficiency. The fuel used, the required parameters of hot water and feed water temperature are designed individual convective surfaces and dimensions of the boiler. The boiler design includes drawings.

A proposal of power plant with steam engine.
Peterka, Lubomír ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
The final thesis deals with the heating plant with piston steam engine design according to heat consumption background in the location of Velky Karlov and with the design of a heating scheme including its explicit parameters. Further on it deals with the possibilities of the heating plant output regulation and with the solution of natural gas and biomass heating plant operations aside the heating period.

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.

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.

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.
