Aspect of reliability in compatibility evaluation of products
Šenkýř, Michal ; Kovář, Miroslav (referee) ; Koška, Petr (advisor)
The diploma thesis deals with stating the aspects of reliability in product compatibility evaluation, namely with stating result uncertainty in product parameters testing and diagnosis which are imperative for introduction of the product to the market. The practical part of the thesis focuses on stating selected uncertainty in warm-water boilers testing, especially in gas fueled boilers with rated thermal input of max. 70 kW.

Steam boiler for waste burning 40t/h
Fejfuša, Martin ; Kohout, Přemysl (referee) ; Skála, Zdeněk (advisor)
This thesis deals with a project of steam boiler to combustion of refused-derived fuel. With respect of required fuel and output parameters of the steam was worked out stoichiometry, energy loss and boiler efficiency, heat flows was allocate to individual heat exchange surfaces. The heat exchange surfaces was calculate and project in detail.

Steam boiler for burnig mix of wood and sub-bituminous coal(mixing 50/50).35t/h
Chmelíček, Jiří ; Kohout, Přemysl (referee) ; Skála, Zdeněk (advisor)
This master´s thesis deals with the constructional and calculation design of the boiler for burning wood and sub-bituminous coal. The work is divided into several parts. First, stoichiometrics calculation and enthalpy calculations of air and flue gas are performed. It is calculated heat balance of the boiler, the boiler losses and the thermal efficiency of the boiler is determined. After designing the combustion chamber thermal calculation is made. Then, the dimensions and individual heating surfaces are proposed. At the end of the calculations are controlling the overall energy balance.

Steam boiler with wood grate firing
Jakeš, Pavel ; Skála, Zdeněk (advisor)
This diploma thesis deals with proposal of the steam boiler on combustion uncontaminated wood. For the specified parameters have been implemented stoichiometric calculations and calculations enthalpy burnt gas. In the next part have been dealt with heat balance of the boiler, the efficiency of the boiler, design of the combustion chamber and calculation of particular rating surfaces. The output parametres are temperature, pressure and the amount of steam.

Steam boiler with natural cirkulation for wood cheaps burning
Vaculík, Jaroslav ; Kohout, Přemysl (referee) ; Kohout, Přemysl (referee) ; Skála, Zdeněk (advisor)
The purpose of this Diploma Thesis is the construction design of the steam boiler with natural circulation for the combustion of wood biomass according to the specified parameters. It is the boiler with the power of 12 tons per hour of superheated vapor output parameters of 3,3 Mpa at a temperature of 400 °C and a temperature of feed water 105 °C. For the specified parameters I first calculated the stoichiometric calculations, boiler efficiency, and followed by using geometrical parameters of the blocks and thermal calculations set design and the number of heat transfer surfaces, depending on the input parameters of the air and water and output parameters of vapor. The work also includes drawings of the boiler.

Energy use of biomass
Streďanská, Alexandra ; Poláčik, Ján (referee) ; Baláš, Marek (advisor)
This bachelor thesis concerns on energy utilization of biomass. The main objective is to compare the combustion process of agropellets and wood pellets. This matter may be divided into two main parts. The first part focuses on research. It discusses the division of biomass and its properties. The second part is fully experimental. It focuses on experimenting with boiler efficiency calculations and describes these experiments. It also addresses the differences in combustion of given kinds of fuels and the subsequent evaluation of the measured results.

Analysis of flue gas in automatic domestic boilers for agropelet
Minář, Marek ; Lisý, Martin (referee) ; Jecha, David (advisor)
The objective of the presented bachelor thesis is flue gas analysis during combustion of agropellets in automatic household boilers. Emphasis is placed on the description of biomass as a fuel, the ways of using biomass for energy purposes, alterations of biomass, production and properties of alternative pellets, automatic boilers and burners for combustion of specific fuel types. The end of the theoretical part is focused on standards and regulations for boiler operation. The practical part verifies the formation of emission on small sources of pollution and determines the concentration of solid and gaseous pollutants. The end of the practical part pursues with comparison of results with legislative requirements and calculation of boiler efficiency.
