Desulphurization of pulverized coal bouler (dry bottom ash) in Teplarna Olomouc
Haluza, Jakub ; Lisý, Martin (referee) ; Skála, Zdeněk (advisor)
This master thesis deals with the feasibility studies desulphurization of powder granulation K3 boiler at Olomouc heating station. K3 boiler burns black energetic coal and after January 1st, 2016 will not meet new more strict emission limits. The theoretical part of the thesis charts usable desulphurization methods from which the semi-dry NID appears as the most appropriate one. In the practical part there is performed a stoichiometric calculation of the flue gas and the balance of raw materials and output products. The possibility of NID method usage is confirmed here. Next the annual operating cost of the desulfurization process is calculated and some NID systems already installed references are presented.

Fireplace Inserts
Ptáček, Martin ; Štelcl, Otakar (referee) ; Fiedler, Jan (advisor)
The goal of this thesis is examination of automatic controller in various operating modes on fireplace inlay Venus 12.1.W. The work compares few measurement, always with measurment without automatic controller In this measurements are evaluated the emissions of CO, CO2, oxygen content in the flue duct gasses and the temperature in the flue duct are listed here and the efficiency is calculated for different operating modes. Conclusion contains overall summary of this thesis. At the end there is a search of manufacturers not only in Czech Republic

Fuid bed boiler for biomass
Bytešník, Jan ; Skála, Zdeněk (advisor)
This master thesis designes the calculation of fluid boiler with specific part - the circular fluid bed. The heat is given by combustion of wood biomass. The thesis is devided into several parts. All necessary elementary results are going to be reached within these parts: an analysis of solid fuel, stechiometry calculation, discussion on output limits and the environmental point of view, definition of elemental heat losses and general heat efficiency, calculation and design of a combustion part and its heat loads and calculation of enthalpies with different ash concentrations. All these phases get to a successful design of the fluid boiler heat balance and sizes of heat-flow surfaces. The composition of the boiler shows the added drawing.

Burners for liquid and gaseous fuels
Zaidullina, Liliia ; Baláš, Marek (referee) ; Kracík, Petr (advisor)
This Bachelor’s thesis is focused on the burners for liquid and gaseous fuels, primarily on the ones that are used in industrial technological equipment. This is a detailed research of available sources including publications and websites in order to describe the classification and construction of burners and their operation and also standards that must be observed. Three main objectives were defined for the paper. The first one is to describe the different types of burners, the basic construction concept of the burners on liquid and gaseous fuels. Usually, the construction of the burner depends on technological conditions of their application. The second objective is to describe the legal standards and basic parameters of the burners. These standards are applicable to industrial burners for gaseous and liquid fuels, which burn with mixture air and fuel. The standards cannot be applied to the burners, in which the additives such as electric or acoustic energy and oxygen. The third objective is to describe the method of offering and calculating burners.
