Belt conveyor for transport of pit cole
Kostelník, Jan ; Kubín, Martin (referee) ; Škopán, Miroslav (advisor)
The goal of my bachelors thesis themed Belt Conveyor for Transport of Pit Cole with maximal granulity 45mm was to design technical concept with: functional concept, calculation of main proportions, design of engine and solidity calculation of the parts which the supervisor told me. The camber of belt conveyoris 12m and land lenght is 45m. Next make: general assembly drawing including prefabricated structure, assembly drawing of straining machinery and next assemblies and next drawings by the instructions of supervisor.

Solid fuels boilers
Sitek, Tomáš ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
This bachelor thesis is focused on solid fuel heating of a detached house. The first section describes most common solid fuels, their composition, characteristics and combustion principle. Following section is about solid fuels boilers with their operation description and most common designs and types. In the end economic and user aspects of four selected boilers are described, such as acquisition and operation costs, operation comfort etc. The resulting graph of total costs over fifteen years can be used for general comparison of selected boilers.

Boilers for house heating
Kádek, Viktor ; Moskalík, Jiří (referee) ; Baláš, Marek (advisor)
This bachelor‘s thesis deals with solid fuel boilers for house heating. It contains information about boilers using fossil fuels and various forms of biomass. The first part is devoted to the search retrieval of solid fuels currently used. Their properties, composition, important technical characteristics and parameters and also their environmental impact are described and explained in this part. The second part contains a brief description and distribution of solid fuel boilers for house heating, comparision of varios types of boilers and an overview of the market for solid fuel boilers in the Czech Republic. The last part of this thesis focuses on calculating and comparing the costs of each type of boiler for the selected reference house.

Horizontal worm conveyor for transport of pit cole
Průša, Ondřej ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
The aim of thesis is to design and process design proposal worm conveyor for transport of small coal. The work addresses in particular the calculation of the main dimensions of conveyors, conveyor drive option, due to possible congestion. It is also attention to the choice of bearings and couplings. The conveyor are inspected strength critical points on the shaft (per deformation, indentations), and place it to the worm shaft and connecting pins. In the last part is given to the operation of the entire facility and its smooth operation.

Coal humic acids and their applications
Hedvigy, Marek ; Taraba,, Boleslav (referee) ; Pekař, Miloslav (advisor)
The dark-colored humic acids are important parts of less coalified coals. Thanks to their properties, they are used in agriculture, veterinary medicine, industry and in modifications of the soil in the environment. In my work, I included the survey of producers of the coal humic acids and their application. An extraction of these humic acids and a determination of their content in the original raw material has been made on a domestic sample.
