Gas Boiler for Blast Furnace and Coke Gas Mixture Combustion
Dohnal, Jakub ; Svoboda, Petr (referee) ; Svoboda, Petr (referee) ; Lisý, Martin (advisor)
This diploma thesis deals with the constructional and calculation design of boiler for blast furnace and coke gas mixture combustion, including sizing of the heating surfaces. The opening section is dedicated to a brief characterization of burned fuels. The following chapter shows the parameters and composition of the resulting fuel mixture. The main part of this thesis involves; determining the stoichiometric amount air required for combustion and the resulting flue gas, determining the boiler efficiency and steam production rate, calculations regarding the combustion chamber and the detailed design of the individual heat exchangers. At the end of the thesis the heat balance of the entire boiler is verified. Drawing documentation of boiler is also part of this diploma thesis.

Using of detonation nanodiamond in tribology research field
Mauer, Milan ; Křupka, Ivan (referee) ; Svoboda, Petr (advisor)
The main objective of this bachelor thesis is to give a general knowledge about nanodiamonds, which are chipped off during the explosions diamonds. These particles are used as additions in lubricating preparations to decrease the friction. Bachelor thesis summarizes the basic characteristics, methods of manufacture and application nanodiamonds in practice. Part of this thesis is dedicated to theoretical and detailed descriptions of procedures and experimental results in nanodiamonds field of study. Another part describes different types of nanoparticles, used for the same purpose as nanodiamonds. The final part sums up the advantages of nanoparticles and its purpose for experimental or practical usage.

Tribological behavior of detonation nanodiamond dispersed in lubricants
Dočekal, Martin ; Čermák, Jan (referee) ; Svoboda, Petr (advisor)
Currently tribological laboratories are looking for a new type of solid ingredients, to create a lubricating composition with minimal friction, heat resistant, with particles well dispersed in oils, sedimentation stable, improving the running properties and to minimize the concentration of solids. Nanodiamonds (DND) could exhibit the possible solution. These particles (in nanometers size) have very good physical and chemical properties, high hardness and resistance. The main advantages are effectiveness at low concentrations, compatibility with various types of oils or environmental safety (carbon additive, unlike metal) in a comparison with other types of additives. However, it is necessary to study these ingredients. The aim of research was to examine the influence of diamond nanoparticles on friction in a lubricated contact (elastohydrodynamic mode). Using tribological equipment, 3D optical profilometer and a microscope, we compared and evaluated using oil with diamond nanoparticles as well as without them. The research focused on the behavior of nanoparticles in contact and the effect they have on friction. To assess these properties of nanodiamonds, EHD optical tribometer was used (this is a device designed for the study of thin lubricating films). 3D optical profilometer and a microscope to assess the wear. And to determine the relationship between the coefficient of friction (COF) and time, Mini Traction Machine was used.
