40/5000 Fine particles produced by the stove
Škvařil, Ondřej ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
This master thesis deals with problematics of fine particles produced during combustion in fireplace stoves. The theoretical part is focused on the analysis of the atmosphere, health consequences, solid pollutants, the formation of particles (origin), particle separation and how they are regulated by laws. Theoretical section of the thesis addresses analysis of biomass and its combustion. In the applied section are listed given methods of the particles measuring according to regulations, common errors during measurement and methods of identification of measured fine particles. Then follow specific measurements of the formed very fine particles produced by the SMPS method. Subsequently, the results of the measurement are evaluated and summarized in the conclusion.

Emissions of solid pollutants
Strnad, Ondřej ; Lisá, Hana (referee) ; Baláš, Marek (advisor)
The thesis deals with issue and properties of solid particles of anthropogenic origin. It describes the principles and technologies for removing them from the flue gas flow and avoid-ing leakage into the atmosphere. It focuses on types of separators, especially mechanical sepa-rators. The work includes an experimental part involving obtaining data characterizing the cyclone separator.

Agropellets for House Boilers
Čaňo, Lubomír ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
This bachelor thesis deals with the characteristics of the agropellets and with their combustion in the house combustion units. In the introduction of the first part is described what the agropellets are and how they are produced. It is followed by a characteristics of the agropellets as a fuel and by their comparison to the other solid fuels. The end of the first part is dedicated to a combustion itself and the creation of emissions during it’s combustion. The second part of the bachelor thesis is focused on a practical verification of the characteristics of the selected agropellets as a fuel. It also includes the experimentally measured values of emissions during their combustion.

Design of an impactor for fine particle separation
Rigby, Jakub ; Sitek, Tomáš (referee) ; Pospíšil, Jiří (advisor)
This bachelor thesis follows up fine particle separation issue with use of impaction method. The introduction is focused on main air pollutants. Closely the solid pollutants and their properties such as formation principle, legislation and human health impact are showed. Following parts describes methods of fine particle capture and closer is focused on impaction method. In the experimental part of this thesis main dimension calculation, construction and manufacturing process of virtual impactor is presented. Several construction and material types of virtual impactor has been fabricated. Finally, a separation efficiency measurement was made. This measurement confirms properties of PM2,5 and PM10 virtual impactor.

Analysssis of Mixtured Pellets Combustion
Somora, Jakub ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
The bachelor thesis focuses on combustion of mixed pellets compared to combustion of mixtu-re of monomaterial pellets. The research part deals with fuel properties of pellets as well as problems arising from the combustion process. It describes the major impact of sintering at biomass energy use, which is also related with the composition of fly ash. It also contains a comparison of the basic parameters of wood and alternative pellets, as well as the emission which are created in process of biomass combustion. The experimental part deals with the ana-lysis and comparison of combustion of mixed pellets as compared to the mixture of monoma-terial pellets. It includes monitoring of emission and solid pollutants content. At the end, the measured data are evaluated and compared to the current standards.

The electric precipitator
Broďák, Kamil ; Patočka, Miroslav (referee) ; Huták, Petr (advisor)
The Bachelor’s thesis is focused on the issue of power separation. The first part describes the principle of power separation process. The second part deals mainly with mechanical parts and their function inside the electric precipitator. The third part focuses on the use of electrostatic precipitators and system management. The last section is devoted to design an electric precipitator according to the specified parameters. Due to the dominance of electric separators company ZVVZ-Enven Engineering, Milevsko from the Czech and Slovak Republics, the work focuses primarily on the products offered by their production program.

Alternative Biomass Fuels Properties
Krejčiřík, Jiří ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
This bachelor thesis follows up attributes of alternative fuels made from biomass and burning them in home combustion equipment with taking into account the process of creating emissions of solid pollutants. There can be found definition of solid alternative fuels with descripition of how are they made and also their attributes as fuels in the first chapter of this thesis. In the second part can be found description of burning alternative fuels made from biomass with taking into account the process of creating emissions. The third chapter of this bachelor thesis is focused on experimental testing of fuel attributes of alternative fuels made from biomass. There is also practical test of creating emissions with focus on creating solid pollutants in this part.

Fine particles emitted from a heat source into the indoor environment
Hájek, Jiří ; Köbölová, Klaudia (referee) ; Pospíšil, Jiří (advisor)
This bachelor's thesis deals with fine particles emitted to indoor space during combustion in fireplace stowes. The beginning of work is focused on the description of biomass and its combustion. In the following part the pollutants, which are produced by combustion of bio-mass are mentioned, and last but not least is attention focused on current air quality in Czech Republic methods of measure of solid pollutants and measuring equipment. Calculation of concentration is closely described in the experimental part, and then the data, which was measured on different modes of operations of fireplace stowes, is presented.
