Project of heating system for house
Svoboda, Lubomír ; Moskalík, Jiří (referee) ; Štelcl, Otakar (advisor)
In the bachelor’s thesis was an analysis of the sources of residential house heating and gas boilers installed at the same time, the proposed condensing gas boiler, heat pump air-to-water and stoves. Comparison of the effectiveness of these heat sources was based on heat loss calculations and laboratory measurements efficiency stoves. Outcome of this work is to design cost-effective and environmentally friendly residential house heating.

Measurement of the properties of solid and liquid fuels (biofuels)
Horák, Jakub ; Štelcl, Otakar (referee) ; Moskalík, Jiří (advisor)
Nowadays there are large numbers of standard methods for measuring the properties of fuels. With the increasing number of new methods to an already confusing issue of measurement of fuel becomes even more confusing. This thesis therefore deals with the measurement of the energy properties of solid and liquid fuels (biofuels). The introduction is carried out searches of solid and liquid fuels (biofuels). Search is focused on the description of each type of fuel, their properties and adjustments to the final form suitable for combustion. The next part deals with the sampling of fuel, which divides the sampling and preparation of samples for laboratory testing. The last section describes the methods of measurement of selected energy fuel properties and selects appropriate methods. Methods of measurement of selected properties is then checked in the laboratory.

Sulfur dioxide emissions
Borýsek, Václav ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with emissions of sulphur oxides. First are described their properties, influence on human health and their impact on the environment. Next thesis deals with present situation of emissions and emission limits. After that selected methods of reduction of sulphur dioxide emissions are described and for representative technology mass balance has been made. Last part describes taken measurements and presents their results.

Verification of emission class of solid fuel boilers
Skoupý, Jan ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This thesis is focused on verifying of emission class of solid fuel boilers. The boilers are described from principle of combustion process in the beginning. The second part divide and describe solid fuels which are intended to burn in these boilers. The third part deals with requirements of legislation of the Czech Republic and European Union. The last part verifies this requirements on the selected solid fuel boiler.

Energy production and use of fast growing trees
Šebela, Jakub ; Štelcl, Otakar (referee) ; Moskalík, Jiří (advisor)
This bachelor thesis is aimed at the theme production and energy use fast growing trees and implements a comprehensive energy balance of production of fast growing trees. The first part is aimed at definition, origin, sources, chemical composition, important energy properties of biomass and how to obtain energy from biomass. The next part is aimed at fast growing trees, especially those that are cultivated in the Czech Republic. This part includes history of cultivation, sources and establishment of short rotation plantations in the Czech Republic. The last part is aimed at energy balance of production of fast growing trees at the short rotation plantations and it also includes economic aspect of short rotation plantations.

Possibilities of Heating of Family House
Řezníček, Jan ; Štelcl, Otakar (referee) ; Lisý, Martin (advisor)
With the growing interest in cost saving and environmental protection we are trying to take advantage of new trends in building insulation and heating. The aim of this bachelor thesis is to present the issues and options for heating these buildings using new technologies and methods, to describe the design of individual boilers, their properties and uses depending on the type of fuel, and to assess the economic performance of selected heating options for a particular building.

Forming of solid pollutants from biomass
Havlínová, Denisa ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This bachelor‘s thesis is divided into two main parts. The first part is research and deals mainly with biomass and pollutants. In this section, we will find a two-dimensional distribution of biomass, a comparison of fuel forms and a discussion of basic pollutants with a focus on solid pollutants. The second part is experimental. It starts with a fuel laboratory, where the water, ash and heat content of the biofuels examined is determined. The following is an investigation of the dependence of the PM formation on the properties of the biomass, which was measured by the measurement of these PM by the filters in the collecting device, while the examined biofuels were gradually burned on the fireplace insert.

Boilers for house heating
Grepl, Martin ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with the issue of small boilers for solid, liquid and gas fuels for heating houses. Its introductory part describes types of fuels, their basic classification, characteristics, and environmental impact during combustion. Various types of boilers suitable for domestic heating are described in its second part. It shows classification according to the type of combustion fuel, advantages/ disadvantages, and also basic parameters of these boilers. The last part of this thesis focuses on calculation of selected boilers in terms of their parameters and cost.
