Assessment of investment in heating house
Zdražil, Pavel ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
The bachelor´s thesis deals with economic evaluation of investment in insulation and heating and resulting operation of boilers in a family house. The calculation of thermal design power, which is needed for heating, was made according to norm ČSN EN 12831 for the house in actual state without insulation. Further were suggested two options of insulations and modernization of windows, for reduction of heat loss. Then was calculated the thermal design power for the two new options, again according to norm ČSN EN 12831. Next were presented possibilities of heat sources. For the specified family house was chosen a gas boiler in classical and condensing implementation for all three variants of insulation. These all options have made six variants which were compared together and evaluated. In the conclusion were excluded four variants economically disadvantageous and was chosen one of the final two variants as the best suggestion for the specified family house.

Power to gas system
Urbánek, Štěpán ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
This bachelor thesis deals with Power to Gas system and its subcomponents. The first part of this thesis is research of the Power to Gas subcomponents. In the second part a balance model of the Power to Gas system is developed based on the traced technical parameters from the first part. The third part deals with traceable implementations of the Power to Gas system and the last part is the design of the system for home implementation.

Separation of water drops from jet of steam
Miček, Michal ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
This thesis is focused on separation water drops from jet of steam. Liested are some of basic principles of separation of moisture and particles, as well as equipment, which are using these principles. Furthemore, this thesis include the part devoted to water drop formation during condesation of vapor. Last part is focused on the design of cyclone separator.

40/5000 Fine particles produced by the stove
Škvařil, Ondřej ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
This master thesis deals with problematics of fine particles produced during combustion in fireplace stoves. The theoretical part is focused on the analysis of the atmosphere, health consequences, solid pollutants, the formation of particles (origin), particle separation and how they are regulated by laws. Theoretical section of the thesis addresses analysis of biomass and its combustion. In the applied section are listed given methods of the particles measuring according to regulations, common errors during measurement and methods of identification of measured fine particles. Then follow specific measurements of the formed very fine particles produced by the SMPS method. Subsequently, the results of the measurement are evaluated and summarized in the conclusion.

Hotwater boiler for natural gas,60 MW, 1,6 MPa, 150/70°C
Gardavský, Jan ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
The aim of this thesis is design a hotwater boiler for burning natural gas with an output of 60 MW. Boiler works with temperature difference 150 °C / 70 °C. For a given fuel is calculated stoichiometric calculation. The following is the calculation of the heat balance of the boiler including the determinativ of thermal efficiency. The fuel used, the required parameters of hot water and feed water temperature are designed individual convective surfaces and dimensions of the boiler. The boiler design includes drawings.

Heating options of a house
Veselý, Přemysl ; Baláš, Marek (referee) ; Toman, Filip (advisor)
The bachelors thesis deals with the topic of heating possibilities of family houses. The work is divided into two parts. The first chapter deals with the search for heat sources used in local central Europe conditions. The practical part deals with economic calculation and economic assessment for used heat sources. Its aim is assess the correct economic intensity of resources used for different family houses, divided by heat loss.

Photovoltaic, as an alternative source of electricity
Floková, Kateřina ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The aim of this work is to provide a description and an explanation of the process of obtaining elektrical energy from solar radiation. There is preliminary mentioned an importance of producing electrical energy from renewable sources and development of photovoltaic systems. The body of the thesis is divided into seven chapters. At first, there is described the principle of transformation solar radiation into electrical energy. Then, the description of types of barrier-layer photocells follows. The types are divided according to their structure and material, which are they produced from. The third chapture is focused on production and construction of photovoltaic modules. Ways, how can be production of electricity increased, are mentioned in the fourth chapture. Advantages and disadvantages of solar concentrators are given there. In the fifth chapture there are described two basic kinds of connection of photovoltaic system. Different ways of taking-off produced electricity are related with those kinds of connection. The last chapture is the fundamental chapture of the thesis. There is given a project of concrete photovoltaic system. For this system is calculated economic return of investment included supposed increase of prices of electricity. In conlusion the author noticed events that would be given and emphasized the outcome of concerete project of photovoltaic system.
