Optimization of biomass boiler
Mizerovský, Karel ; Brázdil, Marian (referee) ; Štelcl, Otakar (advisor)
Bachelor´s thesis solves the problem of measure to optimization boiler of biomass. Theoretic part deals with divided of boiler using solid fuels, exactly boiler focus on biomass combustion. Second part deals with design of deflectors to increase combustion efficiency and practical testing of proposal.

Construction scintillation detector with one aperture for environmental scanning electron microscope
Přichystal, Vít ; Vyroubal, Petr (referee) ; Maxa, Jiří (advisor)
The thesis is focused on the design of a scintillation detector with one screen for environmental scanning electron microscope. At the beginning of the work is an introduction to microscopy. Further work is focused on the description of ESEM microscope and a scintillation detector. The following chapter is devoted to the dynamics of flow. They list the types of flow and mathematical description of equations. The next chapter is about using the software and the way of solution of flow. In the following chapter describes a proposal of the diaphragm and extraction method of the detector area. They are described some of type aperture. The last chapter is the conclusion, where the work is summarized.

Fireplace inlay
Štelcl, Otakar ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
Bacheor´s work is divided into four main parts. First part deal with division of fireplace inlays according to material, construction of combustion chamber, combustion air, heat transmission and used grate. Second part deal with ČSN EN 13229. Majority part of work deal with problematic of measurement instruments, measurement section of combustion products and also with measurement of effectivity of fireplace inlay. Last part of Bacheor’s work speak about possibilities of optimalization effectivity in whole amount of power of fireplace inlay.

Frame of lift
Seják, Jiří ; Pokorný, Přemysl (referee) ; Mynář, Břetislav (advisor)
This bachelor´s thesis is oriented around several parts of electrical traction passenger lift. The main task is to design the conception of lift frame for the lift machine Sassi Toro with a deflector for a loading capacity of 1000 to 1600 kilos. It´s necessary to make a calculation of traction on driving sheave of machine. On the base of these values we are able to asses a maximum ropes distance between the driving sheave and deflector.

Torque momentum of the jet deflector
Kaprinay, Zoltán ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
The aim of this master’s thesis is to determine the torque momentum of the jet deflector of the Pelton turbine using a two-phased CFD simulation. The reason for determining the moments is the inaccurate formula according to a standard, whose results are assumed to be too excessive. The first part is devoted to theory of Pelton turbine and its main components. The second part contains the design of deflector, explanation of the used k- turbulence method and the Volume of Fluid two-phased flow modeling method. The results of the simulation are presented at the end of the thesis.
