Determination of organic compounds in the tar
Magdechová, Andrea ; Čáslavský, Josef (referee) ; Vávrová, Milada (advisor)
The diploma thesis deals with determination of organic compounds in the tar. It is focussed on polycyclic aromatic hydrocarbons, BTEX and n-alkanes. The tar samples were collected by Faculty of Mechanical Engineering BUT Brno during two days and under diferent conditions of biomass gasification. The samples were filtrated and refined using column chromatography on silicagel sorbent. Gas chromatography with mass detection was chosen to determine polycyclic aromatic hydrocarbons and gas chromatography with flame ionisation detection was chosen to determine BTEX and n-alkanes.

Power - plant
Studený, Jan ; Severa, Zdeněk (referee) ; Mléčka, Jan (advisor)
The "POWER - PLANT" deals with the rehabilitation of the former Central Power Conversion and Dale Schoeller (Nejedly I and III) in the village Libušín Mine. Will be newly designed for building the power plant technology with progressive fluidized bed boiler to biomass steam turbine with an output of 7 MW and absorption (trigeneration) unit producing heat, cooling and electricity, which also will function as a cooler primary circuits. The source of water for the power plant will not only former mining pit Nejedlý I which is currently flooded drinking water at about 12 ° C. This system uses high efficiency embedded fuel (biomass), which is ultimately required less. A greater proportion of electricity generated and part of the heat will be distributed to the public network. In most areas will be proposed publicly accessible greenhouses of steel-aluminum construction filled ETFE foil forming the heat insulating membrane filled with air. The reason is to create conditions for the cultivation of tropical and subtropical plants. Greenhouses will be connected to the absorption unit power (underground meanders through which water will circulate), the ventilation shaft mine and mine water - therefore it will be possible to manage the conditions of the internal environment of the building without the influence of the season and especially without mounting other technological devices. It will provide for cooperation with the absorption unit for cooling the primary circuit - therefore eliminating the need for cooling towers or fans. The project will build a detached departments of the Faculty of Mechanical Engineering in Prague - Institute of progressive technologies and systems for energy and the Faculty of Agronomy and Natural Resources CULS. The reason is to allow students and scientists actively and in practice mainly participate in the operation and especially the development of the issue. The public in the area besides themselves open to the greenhouses indoor and outdoor thermal swimming. Part of the entrance hall is a bistro and foremost lecture hall. The aim is decentralized botanical-energy complex of buildings that produce electricity, heat, cooling, and biomass, and creating recreational, educational and research conditions.

Impact of Secondary Air Temperature on Biomass Combustion
Vilga, Filip ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
The main goal of this bachelor thesis is to make research work about the issue of biomass combustion and the experimental realization with practical verification of the effect of secondary air temperature on emmisions resulting from biomass combustion. Theoretical part describes the creation, usage and combustion of biomass focusing on combustion air. The experimental section describes the effect of the temperature of the secondary air on formation of emissions from the combustion of selected biomass type.

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.

Energy use of biomass
Bouchner, Michal ; Špiláček, Michal (referee) ; Baláš, Marek (advisor)
The aim of this bachelor thesis is research of technologies for energy usage of biomass with concentration to production of electricity. In the first part of thesis are analyzed and described technologies producting electricity. In the second part are described suitable types of biomass for each aplication. Following part deals with used aplications for production of electricity in the Czech Republic. Last part shows specific technologies used in the Czech Republic.
