Design of the steam generator for modular reactor
Černý, Marian ; Baláš, Marek (referee) ; Šen, Hugo (advisor)
Subject of this thesis is design of the steam generator for modular reactor. The dissertation consist of the theoretical part, where are described heat-exchangers and steam generators used in nuclear power plants. Second part contains theoretical calculations in the first approach (thermal, hydraulic and strenght calculation). In the next part are particular variants of steam generator selected. For the final variant are necessary calculations (introduced above) and drawings of selected parts are done. In the final statement is technical solution evaluated, and the parameters of the steam generator are compared with actually used steam generators.

Steam boiler for wood burning 40t/h
Mach, Ondřej ; Křemínský, pavel (referee) ; Skála, Zdeněk (advisor)
The purpose of this Diploma Thesis is the construction design of the steam-boiler for the combustion of biomass – wood pellets. For the specified parameters have been defined stoichiometric calculations and calculations enthalpy burnt gas. In sequence, there is designed and solved the configuraion of the steam-boiler, so that the result design and the number of the heat-delivery surfaces can be determined, in dependence on the required inlet parametres of the air and outlet parametresof the water vapour. These parametres mean the amount, the temparature and the pressure. The aim of the thesis is to make a design of the steam.boiler burning biomass according to the set parametres. This very ecological fuel can really substitute the fossil fuel and friendly respect the environment.

Steam boiler for spruce bark burning-18t/h
Dračka, Lukáš ; Heinze, Bedřich (referee) ; Skála, Zdeněk (advisor)
To design a grate boiler with a natural circulation for burning of a pine bark with an output 18t/h is a primary objective of this dissertation. Individual parts of a boiler and it´s heat transfering surfaces were calculated after the working out of stoichiometric calculations from given element analysis of fuel. All computations have to fulfill several parameters: boliler output, temperature and pressure of an overheated steam.

Steam boiler for sorted waste burning 85t/h
Vítámvás, Zdeněk ; Baláš, Marek (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 demolition wood
Mazal, Lubomir ; Skála, Zdeněk (advisor)
The threat of depletion of fossil fuels is the driving force to diversify energy sources in the Czech Republic respectively in the European Union but also worldwide. One of these potential sources are being biomass boilers. The construction of these boilers has expanded in recent years because of government support for the construction of clean energy sources. Whether it is a burning of clean biomass or just incorporation of biomass to fossil fuels, teh substitution of fossil fuels and biomass boilers are the ideal solution. Their major advantages include significant reductions in emissions, mainly sulfur compounds, organic closure of the cycle of CO2 and disposal costs of spent residue.

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.

Steam boiler burning fytomass waste
Plot, Rostislav ; Skála, Zdeněk (advisor)
This thesis deals with the calculation of the boiler on stillage. Nowadays, when there's fossil fuels are just biomass seems adequate compensation. The great advantage of biomass boilers is a small amount of emissions, especially the greenhouse gas CO2. Of a given fuel composition is made thermal calculation and dimensioning of heat transfer surfaces of steam boilers. The resulting calculation must follow the parameters of steam at the outlet from the boiler.

Steam boiler for fytomass
Rotrekl, Jan ; Ing.Pavel Křemínský (referee) ; Skála, Zdeněk (advisor)
This diploma thesis deals with a design of a boiler for stillage combustion. Stoichiometric calculations and enthalpies of combustion gases have been calculated from the specified parameters. In addition, heat calculation, design of the combustion chamber dimensions and dimensioning of heat surfaces were accomplished. The boiler has an evaporator with natural circulation and a fire grate.

Steam boiler for fytomass
Baláš, Jiří ; Ing. Obrovský (referee) ; Skála, Zdeněk (advisor)
The purpose of this Diploma Thesis was the construction design of the steam boiler for fytomass. For the specified parameters of biomass have been gradually implemented stoichiometric calculations of which are further based calculation of enthalpies of combustion gas. In the next part have been dealt with heat balance of the boiler, the efficiency of the boiler, recirculation of exhaust gases and the temperature of the combustion gases in outlet from fire. Thereinafter, the proposal of particular heat surfaces of steam boiler was solved, so that the resulting number and size correspond to the desired parameters. The parameters are temperature, pressure and the amount of steam.
