Brown Coal Power Plants in Czech Republic
Šperka, Radim ; Šnajdárek, Ladislav (referee) ; Špiláček, Michal (advisor)
The thesis describes brown-coal power plants in the Czech Republic. The first part discusses brown coal as a mineral raw material, its mining in the Czech Republic, the impact of mining on the environment and ecological territorial limits.. The second part deals with the Thermo-dynamic working cycles in the power plant. Also deals with various technological parts of brown-coal power plant, including equipment and procedures for the cleaning of exhaust gases. The last part describes the most important individual brown-coal power plants in the Czech Republic, their brief history, the technical parameters and the planned service life.

Boiler for Brown Coal Combustion
Pavlo, Matej ; Hoffman, Pavel (referee) ; Skála, Zdeněk (advisor)
The aim of the master’s thesis is thermal calculation and dimensional design of boiler of 235 t/h which burns brown coal. The work is divided into several parts. In the first part, stoichiometric calculation and the calculations enthalpy of flue gases and air are performed. After calculating the heat balance and loss of the boiler, the boiler efficiency is counted. In the next part, thermal calculation of combustion chamber is calculated. Subsequently, design of the individual heating surfaces is proposed. Finally, the overall heat balance of the boiler is inspected. The calculation is supplemented by drawing of the boiler.

Belt conveyor for brown coal
Babáček, Petr ; Jonák, Martin (referee) ; Malášek, Jiří (advisor)
The aim of this bachelor's thesis is to design of a belt conveyor for transport brown coal for the transport capacity of 140,000 kg per hour and the axial distance between the drums at the both ends of 30 m and height difference of 5 m. The thesis includes a brief description of the belt conveyor and its main parts. Functional calculation according to the current norm ČSN ISO 5048. Then a selection of the individual components was made from the company catalogues. Tensioning device, drive of conveyor and other necessary design solution of conveyor was also designed. Further, the stress analysis of the components of the tensioning device was done and the properties of the transported material are analysed in the final phase of the thesis. The thesis is extended by the required technical drawings.

Grate Boiler for Biomass and Coal Co-combustion
Baláži, Martin ; Ryšavý, Milan (referee) ; Skála, Zdeněk (advisor)
This thesis solves a design of a grate boiler burning wood chips or brown coal with a heat output of 160 MW. Stoichiometry flue gas is calculated according to the specified composition of each fuel. The dimensions of the individual heating surfaces are primarily calculated for burning wood chips and subsequently checked for the combustion of brown coal. Design of the boiler is completed by checking the overall heat output. Boiler design is accompanied by drawing documentation.

The proposal of measurements to fulfill emission limits for boiler of power unit 210 MW
Smokoň, Pavol ; Ing.Ondřej Nechvátal (referee) ; Baláš, Marek (advisor)
This master‘s thesis deals with denitrification of brown coal-fired boiler of electric power plant. First chapters describe technical characteristics of the boiler and possible measurements which would lead to lowering NOx emissions. In order for boiler to meet emission standards valid from 1.1.2016 flue gas treatment by selective catalytic reduction is proposed. Main part of the thesis is thermal calculation of the boiler with modifications necessary in order to apply SCR. The aim of calculation is to determine flue gas exit temperature and temperature at catalyst area in order to assess the suitability of proposed modifications.

Belt conveyor for brown coal
Krahulík, Michal ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
The aim of this thesis is the design of the conveyor belt for coal. The beginning of this thesis is a basic description of the belt conveyor and its parts, then deals with the functional calculation according to the standard ČSN ISO 5048, while the transported material, axial distance, height difference and the required transport power were entered. The calculations also include strength calculations, for example checking the rotation of the axis and the deflection of the shaft of the driven drum, checking the pressure in the threads of the tensioning device. An essential part of the work is the choice of roller stands, rollers, conveyor belt, driven and driving drum, electric engine and the choice of tensioning equipment. There are drawing documentations, which consists of an assembly drawing of a belt conveyor and a weld of the frame of the tensioning station, attach to this thesis.

Belt conveyor for brown coal
Bezděk, Marek ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
The main key in this bachelor thesis is to calculate and design conveyor belt for transport of brown coal for the transport capacity of 140,000 kg per hour and the height difference of 10,5 m and axial distance between the drums at the both ends of 50 m. First part of the work is focused on the main parts of the conveyor belt construction. Then follows the part with the calculation of conveyor belt according to norm ČSN ISO 5048, which is then used for designing of the main parts of the conveyor belt and its dimensions. The thesis is extended by the required technical drawings.
