Cogeneration plants on vegetable oil
Macoszek, Pavel ; Baxant, Petr (referee) ; Radil, Lukáš (advisor)
The thesis is focused on cogeneration units on vegetable oil. The first chapter contains basic information about the production, supply and consumption of electric energy in the Czech Republic and about renewable energy sources. The following chapter is devoted to possibilities of use oil kinds of phytomass in the Czech Republic, or products made from them. Next chapter is mentioned on legislation allowing the use of used cooking oils for energy purposes. It contains a summary of the laws and regulations and options regarding subsidies for electric and heat power. The main objective of these chapters is to explain the issue of the establishment and operation of cogeneration units on vegetable oil. The following chapters are devoted to the design and study of simultaneously operated cogeneration unit on the vegetable oil with a combustion engine and the calculation of economic operation running. The reason of study is to evaluation, which on based of the input values and calculation methods determine the economic efficiency of the project cogeneration unit on vegetable oil under mode purchase price and mode green bonus. Appreciation is also given to the overall legal review and responsibilities of cogeneration units on vegetable oil.

Integration of a co-generation unit to industrial power system
Kučera, Michal ; Holoubek, Jiří (referee) ; Drápela, Jiří (advisor)
This master's thesis deals with the integration of a mine gas burning cogeneration unit into industrial power system. The aim of the thesis is to design and evaluate different possibilities of integration the cogeneration unit into industrial power system. The first, theoretical part of the thesis discuss about cogeneration (combined heat and power). The technologies used for cogeneration are summed up as well as the possibilities of usage. The next part deals with the mine gas as the fuel for the cogeneration units. The lasts chapters of the theoretical part talks about terms for installation power source into industrial power system and about the possibilities of overflow of the electricity into distribution power system. The practical part deals with the installation of the 600 kW cogeneration unit into particular industrial power system. Four possibilities of operation mode of the cogeneration unit are design. At the end of the thesis the brief economical evaluation is accomplished.

Control of c.h.p. unit
Ulver, Martin ; Sutorý, Tomáš (referee) ; Kolka, Zdeněk (advisor)
Master’s thesis deals with cogeneration unit and its control. Cogeneration unit used to energy production and heat production. Power of cogeneration unit is controlled by current consumption of the building, so that the absorbed power from the public network to a minimum. The control unit is composed of two individual part, which is communicated together along single phase of the ~230V. One part measure absorbed power of the network and the second control a cogeneration unit.

Optimizing installation of cogeneration units in family house
Novotný, Jan ; Radil, Lukáš (referee) ; Baxant, Petr (advisor)
The work deals with usage of heat energy from cogeneration unit in a family house. It is focused especially on the use for family house's heating and warming of service water. Optimalization is made on existing cogeneration units. In this work we will handle with two types of cogeneration units of different capacities. From the beginning we concern in current situation and the possibilities of regulation. Further we deal with the possible ways of optimalization of winter and summer running and with the costs for these optimalizations.

Economical appraising of run the power from cogeneration units to different voltage level
Doležal, Václav ; Macháček, Jan (referee) ; Baxant, Petr (advisor)
The topic of the thesis is economical appraising of run the power from cogeneration units to different voltage level. There is sloves in the text, how and under what conditions we can find an optimal solution for the deployment of cogeneration units to the electricity network. The main criterion is the loss of networks and their economic evaluation. We are a description of the different types of cogeneration units, the economic balance and a treatise on losses in electrical networks.

Reconstruction the boiler room PBS Velka Bites
Filoušová, Natálie ; Fiedler, Jan (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with aggregate reconstraction the boiler room PBS Velká Bíteš and includes economic assessment of this reconstruction. The first part completes the earlier and old condition of the boiler room and ecological situation with insufficient cleaning of the combustion products. The short section is about czech legislation in area of emissions and emissions limits. Afterwards are analysed variations of the reconstruction and instalation of cogeneration unit too. Conclusion is comprised by economic evaluation of the variation of natural gas boilers and of natural gas boilers with cogeneration.

Cogeneration
Krčálová, Petra ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
The bachelor thesis describes the design of CHP (combined heat and power) co-generation unit for a particular object. The first part of the thesis is a theoretical introduction to the importance of co-generation it’s advantages and / or disadvantages, the possibilities of it’s use and description of the technology of co-generation plants. The second part of the thesis contains the entire design of cogeneration unit for several different types of the coverage of energy needed. The economic evaluation was used (with prices paid for individual energies are determined by the ERU for 2013 and 2014) to select the most suitable type of the co-generation unit and therefore the best investment.

Cogeneration
Pawlitko, David ; Brázdil, Marian (referee) ; Kracík, Petr (advisor)
This bachelor’s thesis deals with the issue of cogeneration. At the beginning of the thesis, main principles and application of cogeneration are described. Further, various kinds of production of electricity and heat are introduced including comparison of advantages and disadvantages of concrete technology. Another possibility of primary fuel savings are presented too. Thesis also contains Czech and European legislation related to cogeneration, including some changes which bring for year 2013. At the end, heating industry in Czech Republic with its current problems is mentioned.

Biogas plants
Hudečková, Eva ; Moskalík, Jiří (referee) ; Fortelný, Zdeněk (advisor)
This thesis deals with biogas plants. In thesis are described suitable inlet feedstock for anaerobic fermentation, described proces of fermentation and there are mentioned basic elements of biogas plant. In next part of thesis was described concrete biogas plant and there were worked out energy and economic balance. In simplicity there were calculated return of investment and economic benefits for farm.
