Separation of solid particles from biomass burning
Štěpánek, Petr ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
This thesis deals with aspects of the dust particles which occur in gaseous products from biomass combustion. The thesis introduces technologies by which solid particles capture from a combustion flow can be implemented. Principles and technical means of dust particles separation in mechanical separators are put in focus primarily. The thesis is concluded with a technical design of a cyclone separator.

Budisov-Biomass heating plant
Petrovský, Jiří ; Baláš, Marek (referee) ; Fiedler, Jan (advisor)
This dissertation contains a comparison of the real possibilities for heating reconstruction and TUV reheating in three public buildings (located nearby one another) in Budišov township, with resulting recommendations of the best options for local operating conditions. The dissertation contains calculations of heating requirements for particular buildings, a generic theoretical part which summarizes basic data concerning long-term fuels (biomass and natural gas), proposals for technical solutions to heating sourcing concerning these fuels and its prospective distribution from a central boiler house, and its reciprocal comparison from the perspective of the economics of actual realization and operation, and from a perspective of fuel availability and ecology.

Weaknesses of hydrogen energy
Zeleňák, Rastislav ; Elbl, Patrik (referee) ; Baláš, Marek (advisor)
This Bachelor's thesis focuses on exploring and researching the various technologies available for producing hydrogen and their shortcomings. The production of hydrogen, a clean and renewable energy source, has become increasingly important as the world shifts towards sustainable energy solutions. This thesis examines the various methods of hydrogen production including steam methane reforming, electrolysis and production by biological processes. This bachelor's thesis also deals with different methods of storing hydrogen and transporting it. Next, the negative properties of hydrogen are listed, such as its explosiveness, or the degradation of materials used in hydrogen technologies, i.e. hydrogen embrittlement. The work focuses on its characterization, mechanisms and prevention against it.

Steam gas boiler design
David, Josef ; Bursa, Robert (referee) ; Baláš, Marek (advisor)
The diploma thesis deals with the design of a steam gas boiler with a steam output of 50 t/h. The required steam output parameters are a temperature of 425 °C and a pressure of 3,6 MPa. After a short theoretical introduction, combustion stoichiometry is performed. Subsequently, the dew point, boiler efficiency and the amount of fuel supplied to the boiler are calculated. On the basis of further thermal calculations, a dimensional design of the combustion chamber and other heat exchange surfaces is created. The proposed drum boiler consists of three strokes. At the end of the work, control calculations are performed. A design drawing of the boiler is created from the resulting parameters.

Study of the difference between natural gas and hydrogen combustion
Winter, Josef ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This thesis deals with the combustion of natural gas with hydrogen in certain volumetric concentrations. The change in physical parameters due to the addition of hydrogen, which differs in its properties from natural gas, was studied. The thesis is divided into a research part, where the properties of natural gas and hydrogen are described, including a comparison with each other, the effects of gas properties on flame, emissions, or temperature. In the second part, a calculation for the fireplace with chosen dimensions was performed and the changes in physical properties due to the addition of hydrogen were observed and the findings are summarized, which will have to be considered in the design of the fireplace. All calculations are added to the appendices.
