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.

Comparison of Energy Circles from point of view Efficiency
Houdek, Milan ; Škvařil, Jan (referee) ; Lisý, Martin (advisor)
This diploma thesis investigates the combined production of power and heat from biomass. The main aim is to compare suggested energy circles in the light of their electric, general and economic efficiency. Introduction describes the basic terms and principles of energy utilization of biomass, combustion and gasification technology are described thoroughly. The main part contains suggestions and thermal calculations of energy circles. The thermal cycle with gasification chamber, combustion chamber and hot air turbine is proposed, than thermal cycle with gasification generator and cogeneration unit and finally Rankine-Clausius circle. In conclusion calculated results are recapitulated and the usability of proposed thermal cycles is assessed.

Usage of gasification units for electrical power generation
Kučera, Michal ; Mastný, Petr (referee) ; Bartošík, Tomáš (advisor)
The Bachelor's thesis deals with gasification and possibilities of its utilization for electric power generation. It begins with brief historical introduction of gasification and comparison of gasification with combustion. The thesis is particularly focused on coal gasification. Hence the actual role of coal in power engineering is described and some basic coal properties are discussed. In the next part the coal gasification technologies are mentioned. The thesis also deals with cooling a cleaning of the gas. Next to the utilizing of gained gas for power generation, there are other application where gasification can be used. But more attention is paid to the possibility of using gasification for power generation in power plants working with integrated gasification (so-called IGCC) and in consequence, the actual world situation is reviewed. At the end of the Bachelor´s thesis, the power

Biomass gasification with carbon dioxide
Budai, Karel ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This diploma thesis deals with the use of CO2 in gasification of biomass. The theoretical part is focus on description of gasification process and gasification reactors. The next part descripes the influence of the gasifitation medium composition on the properties of the generated gas. The experimental part is devoted to gasification of biomass on a fluidized bed generator, where the effect of CO2 concetration in the gasification medium on the properties of the generated gas is investigated. In the final part is the evaluation of the results.

Gasification of hammer-milled chipboard
Hniličková, Veronika ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
This Master Thesis is about the Gasification of hammer-milled chipboard. The opening part is about general theory of bio-mass gasification and the gasification machines. Next there is a chapter about the products which are included in the gas after gasification and the methods, how to remove them from the gas. This thesis is about gasification legislative acts and novels too. The main body of the thesis is about the experimental gasification in Biofluid 100 machine. This machine is located in the Fakulty of Mechanical Engineering in Brno. There were the samples of gases and tars collected during the gasification. From this samples was made the analysis. Then the mass content BTEX, n-alkans and PAHs.According the process of experiments was set the procedure of gasification. Finally there was a evaluation of the chipboard gasification made.

Energy use of biomass
Střecha, Josef ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
The main task of this thesis is the research of different types of biomass, description of each technology subsequent to obtaining thermal energy for central sources of heat and the mapping of use biomass in a cogeneration production of electric energy and heat. The first part of this thesis deals with the creation and definition of biomass, chemical and physical properties, basic distribution and showing examples of individual representatives. The next part of this thesis describes various options of energy usage of biomass subsequent to obtaining energy for central sources of heat. The last part is concentrating to individual power units in Czech Republic, which exploiting biomass for cogeneration production electric power and heat.

Technologies for energy use of biomass
Záviška, Radek ; Škvařil, Jan (referee) ; Moskalík, Jiří (advisor)
The objective of this work is developing retrieval technology of biomass energy. In the introductory part of the work deals with the definition of biomass, including ways of producing machines for the production and transportation. The main part of the thesis deals with the technology converts raw biomass into valuable energy products. Processing takes place in a straightforward manner the thermal and electrical energy or biomass is indirectly evaluates the products of higher quality, which further downstream processing operations. The indirect processes occur valuable usable energy output in transport, buildings, agriculture and many other industries.
