Combustion of renewable liquid fuels
Nejezchleb, Radek ; Skryja, Pavel (referee) ; Kermes, Vít (advisor)
This thesis is concerned with combustion of liquid biofuels, and possibility of using liquid biofuels for lower heat output power units. Overview of basic usable liquid biofuels in Czech Republic is executed in the beginning of the thesis. This part is focused especially on production method and energy effectivity of rape-oil methyl ester (RME) and bioethanol production. Overview of basic atomization method of liquid fuels is executed in next chapters. The focus is stressed on pneumatic atomization, especially effervescent atomization method, which was used in practical experiment. Practical part contains fossil fuel and selected biofuel (RME) combustion test executed on burner testing device. Basic combustion properties was found and test plan was made before executing the test. Various operating conditions are compared in terms of atomization quality, combustion quality and geometrical characteristics of flame. Usability of tested liquid biofuels for lower heat output power units is evaluated in the conclusion.

Legislative and economic aspects of exploitation of renewable energy sources
Vondra, Marek ; Katolický, Jaroslav (referee) ; Jaroš, Michal (advisor)
The aim of this thesis is a brief outline of legislative and economic issues associated with energy production from renewable sources. After reading the work, potential investors should be connive with the pros and cons of the use of renewable resources. The thesis has a recherche character and tries to provide basic information for the possible preparation of an investment project. Renewable energy sources have become an integral part of the energy market, despite their lack of profitability in comparison with conventional sources. It is a consequence of European Union’s financial support. However, the support is changing over time, as well as avalaible technologies, local conditions and many other factors affecting the current investment attractiveness of renewable energy sources. All these factors must be considered by an investor. The current situation is positive for use of biomass energy, both at home and in large incineration plants and cogeneration units. Electricity can be advantageously produced in photovoltaic and small hydropower plants. There is a growing importance of heat pumps exploitation. We can expect slower development of photovoltaic farms and wind power plants contructions.

Utilizing of liquide biofuels for energy supply in the complex Technicka 2
Kopecký, Jakub ; Fiedler, Jan (referee) ; Pospíšil, Jiří (advisor)
Theme of this thesis is utilizing of liquide biofuels for energy supply in the complex Technicka 2. This work is divided into three parts. The first part dealt with the issue of liquid biofuels, both globally and within the Czech Republic. In the next part are noted technologies for heating, power and cooling of of liquid biofuels. In the third part is noted evaluation of using cogeneration unit from Seva, a.g. for komplex Technicka 2 in different types of traffic.

Possibilities of geographical research in the usage of liquid biofuels in transport
Valeš, Jiří ; Netrdová, Pavlína (advisor) ; Šatra, Jan (referee)
At first there is briefly shown the history of usage and present usage of liquid biofuels in transport. The paper describes its regional differenciation in EU and with the help of basic statistical methods researches the development of differences of the meaning of biofuels in Member States. For these purposes there is created a database of shares of biofuels in energy consumption in transport. If we understand the shares of biofuels showing the intensity or the meaning of biofuels usage, we can exemine its differences. With the help of Lorenz curve there is described the development of rate of inequality of biofuels production. There is also evaluated the meaning of biofuels production in Member States by relativising it to the area of arable land. Key words: liquid biofuels, statistical analysis, spatial analysis

Economic and environmental evaluation of the introduction of biofuels in the CR
Vaníková, Pavlína ; Melichar, Jan (advisor) ; Šedivý, Martin (referee)
This thesis deals with the economic and environmental problems of biofuels in the Czech Republic and abroad. The goal is retrieval and analysis of economic studies that address economic and environmental impacts associated with the introduction of biofuels policy. Individual economic studies on the environment that are at work that are evaluated by using biofuels policy of macroeconomic and microeconomic models. Results of studies show that the introduction of biofuels policy creates economic and environmental impacts such as deforestation, environment, prices, employment and competitiveness of farmers.
