Solid Fuel Boilers
Skočík, Lukáš ; Špiláček, Michal (referee) ; Baláš, Marek (advisor)
This thesis is engaged in heating of the family house by solid fuel boilers, both fossil fuels and the modern forms of biomass. The first section describes and explains the properties, composition and important characteristic quantities of these fuels. It also discusses the classification, description and processing options of solid fossil fuels and biomass.Then they are briefly described the principles of combustion boilers for these fuels along with their properties, advantages and disadvantages. The last section focuses on the selection of a suitable boiler fuel for the selected reference house.

Thermal Losses of the Biomass Boiler
Suchánková, Lenka ; Milčák, Pavel (referee) ; Kracík, Petr (advisor)
The bachelor thesis focuses on the heat loss of the solid fuel boiler, especially on the loss of heat conduction and transfer to the surroundings. In order to minimalize thermal leaks through the boiler walls, materials with good isolation capabilities must be selected when designing. In Microsoft Excel, a universal mathematical model was created to calculate the heat flux flowing through the flat wall of the boiler, from which temperatures can be obtained on the inside of the wall. The work describes the calculation method on which the model is based and its correctness is verified on an experiment based on sensing of temperature fields of wall sur-faces of equipment burning biomass by thermal camera. The model can be used for a wall with up to 9 layers of material, where the wall can be cooled (heat loss) by air and water.

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.

Boilers for house heating
Kolář, Jakub ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
This bachelor thesis is focused on topic cover liquid fueled boilers with power up to 200 kW used for the heating family house and block of flats. Distribution and characteristics of liquid fuels, formation and processing of oil as raw material in liquid fuel production is reviewed in the introduction. First part of this thesis is mainly focused on heat oils. Boilers applicable to house heating, theirs energetic score and specificity and types of liquid fueled boilers are reviewed in second part. In the last part of this thesis is maked a calculation and shows comparative economical computation of convenient types of boiler application.

Heat sources for home heating
Drga, Pavel ; Špiláček, Michal (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with various heat sources for heating the family house. The first part of the thesis is a research, where the history of heating is summarized, energy sources and types of heating systems are divided and then traditional and unconventional heat sources used in domestic heating are compared. In the second part of this work are made designs of heat sources for heating a specific house. And in the end of the work is made an economic evaluation of the designs.
