Influence of fuel additives for passenger cars
Obytová, Eliška ; Bradáč, Albert (referee) ; Bilík, Martin (advisor)
This diploma thesis deals with the addition of automotive fuels and their effects. The aim was to evaluate the function and efficiency of fuel additives present in the fuel at gas stations, and subsequently to improve the fuels accordingly by adding additional individual chemical compounds. The theoretical part explains the concepts, functions and processes related to fuel additives and the basics of tribotechnology. The practical part deals with the process of testing the properties of fuels, their functions, additional additives and its impact for practical use.

Methanol as an alternative fuel
Balcárek, Ondřej ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
This Bachelor thesis is a topic review of problematics of alternative fuel solutions, in particular of methanol and it's production. The aim was to describe properties and possibilities of use of methanol, not only as fuel, but also as a raw material in chemical industry. The information was obtained mainly from English-written sources. Finally, in conclusion part, use and potential of methanol in period of transition to renewable sources is being reviewed.

Fuel for internal combustion engines
Vrbický, Jiří ; Jedelský, Jan (referee) ; Štětina, Josef (advisor)
This thesis is concerned with basic features of fuels for internal consumption engines, especially their influence on thermal efficiency. It also introduces dividing of fuels and their compare in ecologic, economic and technologic side. It is concerned convectional fuels (gasoline, diesel oil) and alternative fuels (nature gas, bottled gas, hydrogen, biodiesel, biogas, methanol and ethanol).

Boilers for house heating
Grepl, Martin ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with the issue of small boilers for solid, liquid and gas fuels for heating houses. Its introductory part describes types of fuels, their basic classification, characteristics, and environmental impact during combustion. Various types of boilers suitable for domestic heating are described in its second part. It shows classification according to the type of combustion fuel, advantages/ disadvantages, and also basic parameters of these boilers. The last part of this thesis focuses on calculation of selected boilers in terms of their parameters and cost.

Analysis of the Current State of Power Plant
Rak, Vítek ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
This thesis presents the Opatovice nad Labem thermal power station (owned by Elektrárny Opatovice, a.s.), which is a combined heat and power producer employing a cogeneration, an eicient mean of exploiting primary energy resources widely used in heating industry. Firstly, the basic terms of heating industry are introduced along with various designs of heat networks, and the fuels used in the Czech republic are listed. The next part of the thesis analyses the actual state of the Opatovice nad Labem power station. Based on the analysis possibility for better saving of the primary fuel is suggested.
