Jež, Dalibor ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
The content of this bachelor’s thesis is the technical research focused on renewable sources of energy used for family house heating. The thesis is divided into several parts. The first part consists of general information, characteristics and dividing of each renewable sources. There are also their advantages and disadvantages. The second part of the thesis is focused on suggestion of concrete systems suitable for family house heating and is supplemented with their comparison.

Design of the tertiary circuit for a nuclear power plant
Flajsarová, Alexandra ; Baláš, Marek (referee) ; Milčák, Pavel (advisor)
At the beginning of the bachelor´s thesis, a basic description of nuclear power plants is presented. The main attention is paid to nuclear power plants with light-water pressurized reactors. This type of nuclear reactor is the most common one in the world, and i tis also used in both Czech nuclear power plants. A significant part of the thesis deals with the tertiary circuit of a nuclear power plant. Therefore, cooling methods, cooling towers, and condensers are described in the thesis. The main goal of the thesis was to calculate the amount of make-up water in the tertiary circuit of a nuclear power plant with a reactor with nominal output of 1200 MWe and to determine whether a nuclear power plant with these parameters would be capable of operation in the conditions specific for the Dukovany Nuclear Power Plant with the use of make-up water from the Jihlava River.

Optimization of the cleaning of the heating surfaces on the coal boiler K1 in Plzeňská teplárenská
Kostrhounová, Petra ; Tomáš, Zdeněk (referee) ; Baláš, Marek (advisor)
This master’s thesis deals with the assessment of cleaning of heat transfer surfaces of a coal-fired steam boiler. The first part is devoted to the description of the knowledge about the formation of deposits, the deposits influence on the operation of the plant and cleaning mechanisms. Then, basic information on the operation, design and method of removal of deposits of the K1 boiler is summarised. Based on this knowledge, operating data from four summer months of boiler operation are analysed to determine the fouling condition of the boiler surfaces and over fifty graphs are produced showing the evolution of selected operating values between each cleaning cycle of the convective and plate superheater as well as air preheater. Subsequently, a parametric model of the K1 boiler at 60 % output is created in PPSD, which allows a more detailed analysis of the boiler operating characteristics and is used for a more thorough interpretation of the operating data. In addition, two models for higher boiler outputs and three theoretical models of operating conditions with different levels of surface fouling were developed. To verify the accuracy of the developed model, a calculation of heat transfer through the outlet superheater is performed. Finally, the calculation of steam consumption for sootblowing is performed.

Optimization proposal of size of PV systems
Vrzal, Martin ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The master thesis deals with proposal of size optimization of PV systems. According to results of optimization, alternative solutions of photovoltaic system were proposed for family house. From the perspective of costs efficiency were compared investment costs and savings of implementation of electricity supply directly to private consumption. Particularly for each of the proposed solution, profitability assessment of comparing purchasing costs and returns on investment was performed. Theoretical part of the master thesis consists of introduction into solar radiation principles, structure and functionality of photovoltaic systems, electronics inverters and accumulation of electric energy. The practical part is focused on measuring of electricity consumption in particular family house, calculation of sunlight intensity hitting tested house, making various solutions of photovoltaic power plants placed on the family house in order to evaluate returns on investments. In conclusion are summarized all results of investigated solutions according to economics aspects.

Small-scale electrostatic precipitator for domestic wood-burning appliances
Kantor, Tomáš ; Baláš, Marek (referee) ; Brázdil, Marian (advisor)
Master thesis deals with design of electrostatic precipitator for domestic wood-burning appliances. In the opening chapters, principles of electrostatic precipitation are described and a study of existing electrostatic precipitators for domestic combustion devices is made. In the practical part of the thesis, a mathematical model of electrostatic precipitator was created. Based on the mathematical model, electrostatic precipitator was designed and its performance parameters predicted.

Design of a heating system for a house
Peřina, Petr ; Kalivodová, Markéta (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with the proposal of a suitable heating system for a family house. The first part contains an overview of different methods of heating. The second part is focused on the calculation of heat losses and heat demand of a particular family house. In the third part, various heat sources are designed and compared for this object. At the end of the work, these proposals are evaluated and a suitable source, which would be advantageous to replace the existing one, is selected.

Design of heat source for heating
Nevoral, Michal ; Škorpík, Jiří (referee) ; Baláš, Marek (advisor)
The aim of this bacherol thesis is to provide the familiarisation with the most suitable sources used for heating of family houses with main emphasis on heat pumps. The first section describes all possible sources used for heating, which can also be used as a household heating. The second part of this thesis is based on calculated losses which were done for selected house using five different types of heat sources. The thesis is concluded by comparing sources of the heat with the economic point of view.
