Modernization of biomass heat plant.
Sedlák, Martin ; Fiedler, Jan (referee) ; Fiedler, Jan (referee) ; Skála, Zdeněk (advisor)
The thesis examines the suitability of a CHP project in Bystřice nad Pernštejnem, a small town in Vysočina region, Czech Republic, which is currently supplied by biomass central heating. It reviews situation and availability of renewable energy sources and opportunities for CHP both in the Czech Republic and in Europe, including the context of current global developments. The opening chapters are followed with the renewable energy project for Bystřice nad Pernštejnem itself. The current technology, availability of biomass fuel for a potential future project, and possible development of energy sources in the town are analysed. Three alternative solutions for the CHP plant are suggested, with proposal for the technology and economic analysis, and possible future steps of the town council are discussed.

Business Project in the Area of Renewable Resources of Energy
Kerndl, Michal ; Kallabová,, Eva (referee) ; Heralecký, Tomáš (advisor)
The aim of my thesis, which is called „Business project in the area of renewable energy resources“, is to analyze business opportunities in the area of renewable energy resources, which have been highly actual and discussed recently, whether in term of benefit for environment or in connection with international problem of shortness in energy resources. Result of this thesis is, on the basis of the analysis, to define recommendations in the form of optimal proposal for realization. The thesis is engaged in description of current state in the area of the renewable energy resources, their utilization in practice and consequential proposals for realization including project financial plan. The thesis is also engaged in possibilities of state budget and EU grants use.

40/5000 Fine particles produced by the stove
Škvařil, Ondřej ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
This master thesis deals with problematics of fine particles produced during combustion in fireplace stoves. The theoretical part is focused on the analysis of the atmosphere, health consequences, solid pollutants, the formation of particles (origin), particle separation and how they are regulated by laws. Theoretical section of the thesis addresses analysis of biomass and its combustion. In the applied section are listed given methods of the particles measuring according to regulations, common errors during measurement and methods of identification of measured fine particles. Then follow specific measurements of the formed very fine particles produced by the SMPS method. Subsequently, the results of the measurement are evaluated and summarized in the conclusion.

Characterization of the chemical composition of the tar produced in the gasification of biomass
Mahelová, Zora ; Vávrová, Milada (referee) ; Čáslavský, Josef (advisor)
Biomass is a renewable source of energy and represents an acceptable alternative to fosil fuels. Usable methods of energetic use of biomass are combustion and gasification. Main interest is focused on gasification in last years. Gasification is based on conversion of organic material to usable gaseous product called syngas, which can be used as a fuel for energy production. Large amount of tar is formed as a by-product of incineration and gasification of biomass. Tar is composed by various mixture of organic substances, has a negative effect on operating conditions and is a potential threat to environment. Experimental part of this study was focused on analysis of tar obtained by gasification of various kind of biomass. Selected groups of hydrocarbons and oxygen compounds were identified in analysed samples. Individual biomass samples were compared regarding to determined relative content of selected substances. Analysis was done by complete twodimensional gas chromatography with mass spectrometric detection (GCxGC/TOF-MS).
