Household fermentor design
Švec, Jan ; Jecha, David (referee) ; Houdková, Lucie (advisor)
The aim of this thesis is to design a fermentation unit specially adjusted for household operating. Unit processes kitchen and garden biodegradable waste with requirements of low acquisition costs, operating costs and demands of service. Benefits of this unit are production of biogas, which will be utilized in household, and processed of biodegradable waste to nutritious manure. The first part of the work is aimed on description of anaerobic fermentation process and summary of operating conditions. The main part deals with potential of household and garden biodegradable waste for production of biogas and design of fermentation unit. Proposals for biogas utilization and economy of whole project are mentioned.

Design of equipment for thermo mechanical pre-treatment of biodegradable waste
Kolařík, Ivo ; Jedlička, Filip (referee) ; Beňo, Zdeněk (advisor)
The main objective of this master’s thesis is to develop design equipment for thermomechanical pre-treatment of biodegradable waste. An important aspect of the design is taking into account current legislation, sanitary conditions for determining the pre-treated biodegradable material, which also serves as a raw material for biogas production. So the device will be used to monitor the impact of thermomechanical pre-treatment of biodegradable waste for biogas recovery. The following describes the processes of anaerobic decomposition of biodegradable materials and technology, whose main task is intensification of anaerobic decomposition of organic materials. The theoretical work are given various methods of processing and utilization of biodegradable wastes, focusing on kitchen waste and sludge from sewage plants. The next section describes the various factors that may affect the stability of the process of biogas generation. This also results in yield and chemical composition of biogas. A key part of this master’s thesis is to develop technical documentation and an approximate calculation of the hot slurry.

Bio-gas power plant
Mészáros, Gabriel ; Joch, Lukáš (referee) ; Pospíšil, Jiří (advisor)
The master’s thesis is focused on the possibility of using biodegradable materials (animal manure, energy crops, crop waste) in a biogas plant. The first part deals with the mechanism of production of biogas. Described are factors which affect the production of biogas, its composition, properties, utilization and potential substrates. The next chapter deals with the technologies of biogas plants. The main part of the thesis is devoted to a proposal of a specific biogas plant in the Slovak Republic in the Novozámocký district. Included is the processing of design proposal, selection of components and proposal of the layout of biogas plant. The economic evaluation includes quantifying capital and operating costs and profits from the sale of electricity and compost.

Energy balance of biomass heating plant
Žmolík, Václav ; Šen, Hugo (referee) ; Baláš, Marek (advisor)
This thesis deals with a design of a biomass heating plant combinating a Rankin-Clausius cyklus and a CHP unit. The CHP unit fuel is a biogas and the boiler fuel is a wooden chip. The adapted CHP unit regenerates feed-water of the R-C cycles. This design is technicaly and economicalty compared with the Rankin-Clausius cycle without feed-water regeneration by the CHP unit.

Renewable energy sources in the region of the North Moravia
Mazák, Tomáš ; Hrnčířová, Michaela (referee) ; Pospíšil, Jiří (advisor)
The content of this work is to search an overview of basic types of renewable resources in the region of the north Moravia, respectively in the Olomouc region. In this work, are clearly described the main sources that are used in our country, especially the potential of photovoltaic systems, wind energy, water energy and biomass. For each type of renewable source is depicted a principle and the possibility to use just in the region of the north Moravia. In addition, specific applications are described in the Olomouc region, using these energy potentials.

Biogas plants
Hudečková, Eva ; Moskalík, Jiří (referee) ; Fortelný, Zdeněk (advisor)
This thesis deals with biogas plants. In thesis are described suitable inlet feedstock for anaerobic fermentation, described proces of fermentation and there are mentioned basic elements of biogas plant. In next part of thesis was described concrete biogas plant and there were worked out energy and economic balance. In simplicity there were calculated return of investment and economic benefits for farm.

Production of electric energy from biomass
Buřil, Tomáš ; Škvařil, Jan (referee) ; Moskalík, Jiří (advisor)
The objective of this bachelor´s thesis is to summarize possibilities of energy use of biomass, especially a production of electric energy. The thesis describes and shows theoretical principles of used processes, as well as technical devices for getting energy. Among used processes belong combustion of biomass, thermic gasification and anaerobic fermentation connected with production of biogas. Electric energy is in these cases produced in combination with thermic energy, a process like this is called cogeneration. In the second part, technical solution of a biogas station in Vidochov is described. There are also stated reasons for its building, as well as an economic return of the investment.

Utilization of biodegradable waste
Švec, Jan ; Pěček, Jan (referee) ; Beňo, Zdeněk (advisor)
The aim of this paper is to summarize the current situation of the problem using biodegradable waste. The introductory chapters deal with descriptions of different types of biodegradable waste. The main part describes ways of handling this waste. For various types of waste are listed by their most appropriate treatment and further use. Emphasis is placed on legislation dealing with that waste legislation on the processing equipment.
