Energy supply of the complex Technicka 2
Buráň, Petr ; Lisý, Martin (referee) ; Pospíšil, Jiří (advisor)
The theme of this master thesis is „Energy supply to the site Technická 2“. This thesis is divided into several parts. First we will get in touch with concept of combined heat and power and also with principle of photovoltaic electricity production. We will continue with description of site before and after reconstruction. Then we will follow with analyze the effect of reconstruction on energy consumption. In the end we will make some suggestions for using the local source of heat and electricity in Faculty of mechanical engineering, Brno university of technology. All suggestions will be analyzed from energy and economic point of view.

Heat sources for home heating
Drga, Pavel ; Špiláček, Michal (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with various heat sources for heating the family house. The first part of the thesis is a research, where the history of heating is summarized, energy sources and types of heating systems are divided and then traditional and unconventional heat sources used in domestic heating are compared. In the second part of this work are made designs of heat sources for heating a specific house. And in the end of the work is made an economic evaluation of the designs.

Integration of Waste-to-Energy Plant into the District Heating Network with Existing Heating Plant
Kopecký, Václav ; Janošťák, František (referee) ; Putna, Ondřej (advisor)
The main two goals of this thesis are summarization of current state of waste management policies in the Czech Republic and introduction of possibilities connected with waste-to-energy strategy. This thesis is divided to 4~sections, each of them focused around different part of this complex problem, or issues directly connected to it. In the first part, state of waste management in the Czech Republic is discussed from several different points of view. Then, district heating is introduced as a solid platform for waste-to-energy facilities. The last two chapters present several other issues, connected with construction of new waste-to-energy plants and methods of optimization of long term rentability models.

Energy supplies fairgrounds
Foit, Vladimír ; Skála, Zdeněk (referee) ; Pospíšil, Jiří (advisor)
The diploma thesis titled Energy supplies fairgrounds is divided into four parts. The first part is devoted to the theory of sources of froze and heat energy. The next part deals with current condition of energy supplies of fairgrounds. The third part is based on the design of possible adjustment of energetic management for both the whole compound and partial objects. The last part sums up all the adjustments and evaluates all the real variants by closer economic analysis.

Possibility of using alternative sources of energy in manufacturing facility
Malchar, Jakub ; Skála, Zdeněk (referee) ; Pospíšil, Jiří (advisor)
The Master’s Thesis prospects the suitability of installing a photovoltaic system and a cogeneration unit in the LIPOELASTIC manufacturing facility and proposes their actual realization. Theoretical part describes said facility, its current energy supply situation and presents the proposed realizations' principle of operation. Practical part contains concrete calculations needed for realizations' proposal and their economic evaluation both independently and jointly.

progressive trends in energy exploitation of fossile fuels
Horák, Pavel ; Přibil, Rudolf (advisor) ; Matějíček, Luboš (referee)
This paper, as literature retrieval, evaluates progressive trends in development of technologies for energetic use of fossil fuels. The introduction is focused on reasons for increase of energetic efficiency of combustion processes, especially reasons for using of fossil fuels and their consumption over the world and in Czech Republic. Next chapter focuses on mainly used fossil fuels, which means coal, crude oil and its derivatives and natural gas. Those are evaluated in term of quality and historical progress, too. Fundamental chapter analyses particular improvements but also complex technologies used in energetic, for example using of gas turbines, assets of Kalina cycle, complex technology of Integrated Gasification Combined Cycle (IGCC), combined heat and power production (CHP), combined cycle gas turbine (CCGT) or pressurised fluid bed combustion (PFBC).

Heat sources for industrial buildings
Vejnarová, Nikola ; Počinková, Marcela (referee) ; Formánek, Marian (advisor)
The thesis is focused on the design of the new heat source of the existing building. The first part deals with the heat sources and fuels used in the Czech Republic. The second part includes design of three variants of heat sources: gas boilers, cogeneration unit with the electric boilers and cogeneration unit with gas boilers. The individual variations are also evaluated in terms of user comfort, space requirements or economy of operation. The third part includes measurement and evaluation of internal environment of the dining hall.

Project of family farm as closed economic unit
Jakubčík, Václav ; Pazderů, Kateřina (advisor) ; Zdeněk, Zdeněk (referee)
The diploma thesis deals with the family farm, which deals with fast growing trees cultivation. Business plan for my firm is the operation of the cogeneration unit and ensuring its self-sufficiency. The intention is that the family farm should produce more than half the biomass for cogeneration units.
Diploma thesis works with providing services in processing of logging residues, removing seeding trees and transportation. All this in order to obtain sufficient quantities of the commodity for the operation of boiler plants with cogeneration unit. Further outputs are addressed including the use of waste heat. Necessary support in planning the boiler room is the SWOT analysis. Conclusion of SWOT analysis clearly support the business plan for hte operation of a family farm.
Another key factor, that motivates me to expand current boiler room is a continuously rising electricity price. I suppose part of the generated electric power will be used for wood drying, the rest of the energy power is supposed to be sold to CEZ. Revenue from electricity sales should improve my Cash-Flow.
An important source of energy is a waste hot water that will be used for heating lumber drying, rabbit slaughterhouses of Rabbit firm. The rest of hot water waste will be used for heating workshops and residential buildings around.
The main incentive for founding a family farm is request to have enough fuel for the cogeneration unit also in case of external source shortage. The target is to ensure fluent economic operation of whole technological equipment.
My target is an overall economic assessment of the project for extracting of biomass from various sources. After an overall assessment we got conclusion, that the project can be profitable especially due to own production. Services provided by my farm creates significant additional value.
For family farm founding motivates me also unemployment of several family members.

Cogeneration unit at the wastewater treatment plant
Hoferková, Lenka ; Hlavínek, Petr (referee) ; Hluštík, Petr (advisor)
Energy management is topical issue and we have to solve this global problem. There is also an option to exploit the renewable energy. The source might be biogas produced during anaerobic sludge stabilization. This bachelor thesis deals with using biogas in cogeneration units at sewage water plant. First section covers the main Czech and EU legislation and regulations in the field of water treatment, sewage sludge treatment and cogeneration. The next section is devoted to production of biogas and possibility of utilization in cogeneration. The thesis divides cogeneration systems and mentions the main parameters such as energy efficient and wattage. Local and European companies are chosen from the fields of manufacturer. The practical part deals with designing of cogeneration unit at sewage water plant Zdar nad Sazavou. According to calculated and measured parameter adequate unit from local manufacturer Tedom is chosen. Moreover, there are other solutions for replacing the engine in the current unit (by Tedom) or general repair (by Motorgas). All options are evaluated from the view of profitable investment. The conclusion is that It would be preferable to replace the engine.
