The Combustion of Organic Lightweighting Agents in the Chamotte Materials
Smékalová, Veronika ; Keršner, Štěpán (referee) ; Sokolář, Radomír (advisor)
Lightweight chamotte products are popular building material. There are many types of lightweight chamotte on the market, but the most popular lightening options are organic ingredients. This brings some problems to the production of these products. This thesis deals with the burning of various types of lighters from shards of fireclay materials. In the theoretical part are summarized raw materials, which are necessary for production of lightweight chamotte. The results of the published research studies on the topic of lightening of organic lightening products are being described here. The practical part deals with properties of products made of clay or kaolin with the addition of a certain amount of lighter. These added lighters are spruce sawdust, beech sawdust, peat, bran, paper slurry and anthracite. All these lighters are direct. For comparison, the cenospheres, which represent indirect lightweights, were also included in the research. For all specimens, the temperature interval of burnout of specimens, refractoriness, classification temperature, bulk density, thermal conductivity coefficient and other properties were defined.

Electrolytes containing a phosphorus-based flame retardant
Pelikán, Ondřej ; Libich, Jiří (referee) ; Máca, Josef (advisor)
The diploma thesis is focused on the theoretical knowledge of lithium accumulators. More attention is given to electrolytes and especially to flame retardants, where the types and individual examples of flame retardants are described more detailed. The practical part is focused on the individual laboratory measurement of selected samples of electrolytes with different flame retardants. The measurement results are analyzed in other parts.

Modelling of air flow in combustion chamber ZKG
Krišpín, Jan ; Lisý, Martin (referee) ; Špiláček, Michal (advisor)
The subject of the submitted bachelor thesis is a description of chemical and physical behavior of biomass, methods of energetic transformation of biomass, processes in a combustion chamber during burning and primarily flowing of combustion air. A part of this thesis is a modelling of an air flow in the combustion chamber using the finite elements method with an evaluation and a suggestion of construction changes of the combustion chamber.

Fireplace inlay
Štelcl, Otakar ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
Bacheor´s work is divided into four main parts. First part deal with division of fireplace inlays according to material, construction of combustion chamber, combustion air, heat transmission and used grate. Second part deal with ČSN EN 13229. Majority part of work deal with problematic of measurement instruments, measurement section of combustion products and also with measurement of effectivity of fireplace inlay. Last part of Bacheor’s work speak about possibilities of optimalization effectivity in whole amount of power of fireplace inlay.

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.

Quality control of biodegradable waste process
Krbalová, Maria ; Fiala, Alois (referee) ; Koška, Petr (advisor)
The waste production and especially biodegradable waste is following mankind since the beginning of his existence. This thesis deals with a description and dividing of current available waste process technologies, including description of their advantages and disadvantages. The work is also focused on the more detailed description of the composting technology, its control and opportunities to influence on resulting parameters of compost product. The information about technical description of workplace equipments, including industrial and technological processes was provided by the company VIA ALTA from their compost plant in Blansko.

Natural biomass burning and character of emissions of these processes
Maňo, Martin ; Köbölová, Klaudia (referee) ; Chýlek, Radomír (advisor)
This bachelor thesis deals with the issue of emissions from natural biomass fires. Emphasis will be placed on aerosol emissions that occur during these natural phenomena. The introduction will discuss in general the natural fires of biomass in the world and their impacts. The next part of the work will investigate the factors that affect the composition, size and composition of aerosols, as well as their impact on living organisms and the environment. Methods will also be described for determining whether an aerosol trapped in the environment is of anthropogenic or natural origin. In the last part, the author will deal with the analysis of data from the measurement of real biomass combustion, in which he will participate

Evaluation of technology for the biomass incineration.
Trna, Lukáš ; Tabasová, Andrea (referee) ; Jícha, Jaroslav (advisor)
The objective of this bachelor‘s thesis is to provide general information about biomass and technologies for its using. The thesis is diveded into four main parts. The first part describe sources of biomass, its adaptation and its processing for energy purposes. The second part is more comprehensive and mentions individual technoligies and possibilities of final using of biomass. The third part sums sup ecological falls and efects of production biomass on environment. The fourth part deals with economics and compares costs of the most available technolgies for gaining thermal energy.
