Technology to remove sulfur oxides (NOx) from flue gases for large combustion plants
Hrubý, Radomír ; Bojanovský, Jiří (referee) ; Jecha, David (advisor)
In the specified large combustion plant, fuel with a large content of sulfur is burned. The current desulfurisation method is not able to meet the new emission limits, therefore it is necessary to design an adequate desulphurisation method. The theoretical part of this diploma thesis contains a description of the legislation related to emission limits for large combustion plants and an analysis of individual technological methods of desulphurization together with a description of the relevant sorbents. The practical part of the work contains a design of dry conditioned sorption with the using of a calcium-based sorbent. The basic technological and structural design is designed together with the spatial solution and dispositional solution of the whole technology.

Technology to remove nitrogen oxides (NOx) from flue gases for large combustion plants
Kučera, Jan ; Brummer, Vladimír (referee) ; Jecha, David (advisor)
This diploma thesis deals with selected abatement techniques of nitrogen oxides (NOx) developed for large combustion plants. The first part describes selected NOx, their properties and explains the formation during combustion. Furthermore, there is an analysis of current legal legislation regulating the issue of emission limits. The third part presents selected primary and secondary measures that are widely used. The emphasis is placed on the description of selective catalytic (SCR) and non-catalytic reduction (SNCR). Finally, the basic design of these technologies for model combustion equipment is performed. The consumption of reducing medium and the volume of the catalyst for the mentioned techniques are calculated here. The estimate of selected operating and investment costs is a part of the basic scheme.

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.

Chemicals for waste water treatment
Doskočilová, Denisa ; Vachovec, Roman (referee) ; Hluštík, Petr (advisor)
The aim of this bachelor thesis is to get the reader acquainted first with the history of wastewater treatment in the Czech Republic and also the legislation that relates to waste water treatment. Furthermore, this work will provide an overview of each part of technological wastewater treatment plants and chemicals that can be used in various cases, including their manufacturers and prices. In the practical part there will be conducted a calculation of the amount of coagulant including its annual costs for WWTP Čebín. This material may be an inspiration for either design offices or water managing companies and also the general public.

Emission Levels for Tractor Engines
Vaško, Roman ; Beran, Martin (referee) ; Dundálek, Radim (advisor)
This bachelor’s thesis deals with the emission standards of tractor engines. There is a tightening of standards in recent year generally. The former part of the thesis contains description of specific pollutants that are exhaled into the air. The second part is focused on newly presented Tier 4i standards (Stage IV). The third part includes technologies, which provide engines to meet new regulations. The last chapters deal with an overview of the largest manufacturers of tractors, including Zetor, and their approach to emissions.

Gasification of hammer-milled chipboard
Hniličková, Veronika ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
This Master Thesis is about the Gasification of hammer-milled chipboard. The opening part is about general theory of bio-mass gasification and the gasification machines. Next there is a chapter about the products which are included in the gas after gasification and the methods, how to remove them from the gas. This thesis is about gasification legislative acts and novels too. The main body of the thesis is about the experimental gasification in Biofluid 100 machine. This machine is located in the Fakulty of Mechanical Engineering in Brno. There were the samples of gases and tars collected during the gasification. From this samples was made the analysis. Then the mass content BTEX, n-alkans and PAHs.According the process of experiments was set the procedure of gasification. Finally there was a evaluation of the chipboard gasification made.

Marketing management of cement filtration technology for construction industry in Czech and Slovak republic
Beránek, Petr ; Boxhofer, Martin (referee) ; Linkeschová, Dana (advisor)
Globally, cement industry is one of the most energy consuming industries. Moreover, production of emissions as dust, CO2, NOX, SO2 and heavy metals from manufacturing process is considered as environmentally harmful. However according to predictions of World Wildlife Found (WWF) and International Energy Agency (IEA) global cement demand is going to increase in next decades. For appropriate cement industry understanding data about production of harmful emissions were collected and cement production process was described in the thesis. The thesis mainly analyzed potential for Upper Austrian Company Kappa GmbH to install dedusting system on Czech or Slovak cement plants in next 2-3 years. Kappa´s dedusting systems are able to significantly reduced dust emissions exhaust from cement plants. However as for Company Kappa GmbH cement industry is a new industry branch in which company would like to operate in future, therefore certain objectives have be to overcome. The thesis found those objectives and gives recommendations for their solutions.

Efficacy overflows
Šlechtová, Tereza ; Úterský, Michal (referee) ; Hluštík, Petr (advisor)
The aim of this bachelor´s thesis is to process the recherche of the overflow chambers The first part of this thesis includes the legislation of the overflow chambers. The following list provides a short description of the individual types of the overflow chambers and building materials which we use the most often. The thesis deals with technical proposal and hydraulic computation.The allovable pollution of diluted water is presented by dint of emission limits and pollution limits which are caused by the overflow chambers. In the practical part of this thesis are used valuable lessons learned from the theoretical parts. The aim of this part is recognition of the selected overflow chambers in the combined sewerage system in the city of Brno. The chambers were monitoring during measuring campaign in 2017. The overflow chambers were evaluated to their efficiency and construction conditions. In the latest bulit and current moved overflow chambers was calculated the ratio of dilution.
