Change John Thomson boiler fuel base
Hradecký, Martin ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This Thesis deals with thermal control calculation of the existing John Thomson steam boilers burning heating mazut and subsequent thermal conversion to natural gas. The main parts of the calculation are as follows: stoichiometry, thermal balance, conversion of the combustion chamber and heating area.

Steam boiler for biomass and sand 92,5t/h
Špiláček, Michal ; Lisý, Martin (referee) ; Skála, Zdeněk (advisor)
This master’s thesis is dealing with design of steam boiler for wood chips. Wood chips are considered as biomass and so the steam boiler is considerate to enviroment. Main purpose of this work is calculation of size and number of water/steam heating surfaces so the boiler can produce steam with required parametres of temperature, pressure and amount.

Modular absorption cycle
Honka, Pavel ; Pavlů, Jaroslav (referee) ; Pospíšil, Jiří (advisor)
The thesis is focused on the cooling cycles, namely cycles of absorption. The work is divided into several parts, as problems to be solved. The first part deals with the principles and using refrigeration cycles in practice, their involvement and by comparing the working pairs of substances circulating in the absorption unit. The practical part deals with making a proposal for one-and two-level modular absorption cycle of 6 kW, and the subsequent techno-economic comparison with commonly supplied absorption unit

Steam boiler burning wood 60t/h.
Dufek, Adam ; Baláš, Marek (referee) ; Skála, Zdeněk (advisor)
The aim of the work is to design a plain wood combustion boiler of 60 t/h output. Fuelling component analysis has been added to the basic boiler parameters. Stechiometric calculations were performed for given fuel composition. Thermal efficiency was set after making thermal balance. Separate convective areas and boiler proportions were designed together with separate steam output parameters (temperature, pressure, amount). Design documentation was added.

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 burning wood 60t/h
Umýsa, Radovan ; Baláš, Marek (referee) ; Skála, Zdeněk (advisor)
This diploma thesis deals constructional and calculation design of the steam boiler 60t/h of clean burning wood. For the parameters of the stoichiometric calculations are carried out and enthalpy calculations of combustion and air. The collected data is then made It a diagram of air and flue gas. The following are the calculations with the heat balance calculations of losses and determination of the boiler thermal efficiency of the boiler. It is made of the combustion chamber design and its thermal calculation. After determining the main dimensions of the combustion chamber moves continue the calculation of boiler heating surfaces. At the end of the calculations are controlling the overall energy balance. Boiler output parameters as temperature, pressure and quantity of the steam.

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 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.
