Cogeneration Unit
Černý, Jakub ; Hrnčířová, Michaela (referee) ; Fiedler, Jan (advisor)
The aim of this thesis is a technical-economical design of cogeneration unit for drying of biomass resources for the subsequent processing. The first part of this work is devoted to biomass. There is described in detail its division into various types, their characteristics and usage, as well as the technology of drying and processing the biomass into forms of normative fuels and description of cogeneration devices that use biomass as fuel. The second section lists the input parameters from the investor for the subsequent calculation of the thermal cycle and cogeneration source selection. The last part is devoted to technical and economical evaluation of various design options and offering the better option for implementation.

Cogeneration
Martinek, Jan ; Šnajdárek, Ladislav (referee) ; Fortelný, Zdeněk (advisor)
This bachelor thesis is intended to handle the issue of cogeneration. There is presented the principle of cogeneration and its benefits. Cogeneration is compared to the separate production of power and heat. This work deals with the storage of electric energy and heat and also deals with used batteries. The next chapter discusses the impact of cogeneration to environment and at the end there are mentioned the main Brno’s cogeneration units and central heat distribution in Brno.

Fundamentals of cogeneration and its application in Brno
Kubiš, Zdeněk ; Škvařil, Jan (referee) ; Martinec, Jiří (advisor)
The bachelor’s thesis deals with the cogeneration – Combined Heat and Power. It describes its main principles and advantages. It presents the most important types of cogeneration technologies with an emphasis on high-power units and summarizes the main areas where the cogeneration can be applied. Further, the State Energy Policy of the Czech Republic in the heat production is introduced. In the last part, the thesis is concerned with the history and the current state of heat production in Brno and gives an overview of the heating stations in the city.

Problems with sulphur and silicon in biogas
Holub, Radim ; Jecha, David (referee) ; Beňo, Zdeněk (advisor)
The main objective of this bachelor’s thesis is a description of a composition of biogas (BG) and contained undesirable components, which include especially sulphur and silicon compounds. In an introductory chapter is given a definition of the biogas, principle of its creation, chemical composition and a share of undesirable components. In following chapters are described single undesirable components, their properties and negative impact on parts of equipment using biogas. The following are the methods to reduce the critical concentration values of these components or their complete removal from biogas. In the thesis are also given practical solutions to eliminate these undesirable components.

Cogeneration power plant
Ptáček, Martin ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
This bachelor thesis deals with heat and power supply of the family house, which uses natural gas.The first part reveals cogeneration technology in general, especially cogeneration unit based on gas-engine (internal combustion engine).In the second part, the thesis focuses on energy budget (power-balance sheet) issue. Finally, the third and fourth chapter, deal with particular calculation of usability of cogeneration unit in the small family house. Due to a small final financial difference and large investment costs, with such a low heat and power consumption, this technology is unsuitable for this type of usage.

Effect from used biomass for economic traffic of biogas station
KMOCH, Vít
In this bachelor thesis are processed information and notions, associated with production of biogas and biogas station. Literary review is focused on the process of creation biogas, using biogas, the basic information about biomass and biogas stations, stability of process biogas station and the basic information about digestate. In the practical part of my bachelor thesis I introduced information about farm and biogas station, which is owned including technical solutions and a description of the most important components by biogas stations. Then I was following up with the measuring of the optimal daily feed biomass feedstock, gas potential and economic evaluation of biomass, depending on the quantity of biomass and produced electrical energy.

Mechanization intensive composting technology
HLAVINKA, Pavel
This bachelor thesis is focused on the intensive compost technology and the biogas production of the biologically decomposable waste. The theoretical part describes the technology of compost production in the tracked piles as well as in the loose areas, followed by the description of the biogas technology and biogas stations with all the related equipment. The biogas is the main product of the anaerobic digestion. Subsequently, we describe the conditions necessary for the biogas production, e.g. the constant temperature, pH, and the nutrients? presence. In the field part of the thesis there we describe the AGRO?Otročín plc. biogas station, as well as the technology hereby in use and its individual parts with the concrete values and figures followed by the basic characteristics of the cogeneration aggregate and the noise level measurements of the technology presented.

Propose and evaluate the use of heat produced in cogeneration units of biogas stations.
KUNEŠ, Radim
The goal of this bachelor thesis is to propose and evaluate the use of heat produced by combustion engines in cogeneration units of biogas stations. The introductory part deals with the generation of biogas, with its composition and conditions of its production. Other factors that are mentioned are in-put raw materials and their impact on biogas yield. Furthermore, cogeneration units and their engines are described. The next chapter is dedicated to the description of the biogas station Novosedly. Various biogas station components are mentioned as well as in-put raw materials and technologies used. The values of the produced heat and electric energy are processed along with the amount of produced biogas. Amount of in-put raw materials and produced digestate are taken into account in this calculation. The last part focuses on the evaluation alone of the heat balance and it proposes a project how to use the waste heat from cogeneration unit together with its financial assessment.
