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.

Pollution control strategies and techniques for combustion processes
Kunc, Vlastimil ; Chlápek, Petr (referee) ; Bělohradský, Petr (advisor)
Bachelor’s thesis deals with the problems of combustion process. The work gives the overview and the description of individual design parameters of the combustion facility. The analysis of the influence of design parameters on emissions formation is followed by the description of individual kinds of emissions and their impact on the environment. Next the most used reduction techniques are described. The work is closed by the overview of the emission limits in the Czech Republic.

Modern low-emission combustion chamber for jet engines
Mašek, Jakub ; Nastálek, Ondřej (referee) ; Šplíchal, Miroslav (advisor)
Bachelor´s thesis examines modern low-emission combustion chambers for jet engines. It´s foremost aim is to specify construction parameters of low-emission combustion chambers, compare it´s features and comprise the use of these combustors in civil aviation. Thesis deals with reasons of modern low-emission combustion chamber development and estimate future development in the region of aircraft industry. Another aim is to specify legislations of aviation emissions, history of certification standards and organizations, which make and control these limits.

Production of Unmeasured Emissions by Combustion in House Boilers
Chlubna, Martin ; Lisá, Hana (referee) ; Lisý, Martin (advisor)
This bachelor thesis deals with the production of non-monitored pollutants during combustion in domestic boilers. The theoretical part is made up of a research study dealing with pollutants and their legislation. In the experimental part combustion tests for coal and wood of different moisture are made. In conclusion, the measurement results are evaluated on the basis of chemical analysis.

Appliances for solid fuel for heating
Lackovič, Roman ; Hrnčířová, Michaela (referee) ; Štelcl, Otakar (advisor)
Bachelor's thesis "Appliances for solid fuel for heating" aims on the issue of emission measurement for solid fuel boilers. The first part is a theoretical introduction, where solid fuels are described, following are the types of appliances, which are powered by solid fuels. There are described legislation related to emission limits and principles of devices used for measururing emissions of solid fuel appliances at the end of the theoretical part. The second part is the attention devoted to description of measurement, that we have done, calculation of efficiency and emissions for measurement. Lastly, there is specified emission class to which the boiler, according to measurement, belongs.

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.

Impact of Biomass Storing on Heating Value
Černý, Michal ; Špiláček, Michal (referee) ; Lisý, Martin (advisor)
The main aim of my bachelor´s work is the experimental verification of the landfill impact on the parameters biomass. The first part deals with definition, the formation of a basic biomass division. In the next section we find the issues concerning the burning, fuel composition and emissions during combustion. The last part deals with the influence of climatic conditions on the biomass degradation. In the experimental part were measured calorific calorimeter. The result was that, after a measured period of five months to avoid significant degradation of the fuel.

Analysis of the Indicators of the DEZA, a. s. Company Using Time Series
Kratochvíl, Bohumír ; Doubravský,, Karel (referee) ; Kropáč, Jiří (advisor)
In his final paper, the author examines and evaluates the statistical indexes of chemical factory DEZA, a. s. that have certain environmental aspects. The analysis itself is based on theoretical findings related to the regressive analysis and time series. Furthermore, the author designed an application in Visual Basic programming language that automatically solves math problems introduced in the final paper. The author also introduces a suggestion on how to improve the company's image.
