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.

Electromagnetic field scanner and its utilization in EMC measurement
Chupáč, Michal ; Číž, Radim (referee) ; Kubánek, David (advisor)
Master’s thesis is focused on making the acquaintance of EMC issues and ways of electromagnetic field scanner RS321 utilization for pre-compliance measurements. First part contains analysis of available equipment’s influence on measurement results on the basis of gathered specification. Next part includes an example measurement used as operational manual for scanner and its controlling program. The most important part is correction evaluation for performed EMI measurement of signal generator using its EMC certification protocol and application of gained correction curve on independent EMI measurement of device tested by EMC testing laboratory. Other possibilities of scanner utilization are mentioned in the next chapters. Last part of the thesis contains suitability evaluation of EMC scanner on the basis of findings from performed measurements.

Current trends of reduction NOx in the context with the prepared legislation
Růžička, Pavel ; Brummer, Vladimír (referee) ; Jecha, David (advisor)
This bachelor's thesis deals with processes of generating and methods of abating nitrogen oxides contained in flue gases in the context of Czech and European legistation. It compares the new enviromental act with its predecessor and scetches the pull of the new emission limits on stationary sources of air pollution. With particular focus on NO and NO2, the summary of NOx compounds hands a brief review of every individual one, which amongst other matters includes their impact on public and enviromental health. In the next part the paper aims at primary and secondary measures of NOx reduction together with factors influencing their utilization. Last chapter inquires into methods of selective catalytic and non-catalytic reduction and means of thier engagement in industry.

Purification of flue-gas desulfurization
Křesťan, Jan ; Špiláček, Michal (referee) ; Hrnčířová, Michaela (advisor)
The aim of this thesis is theoretical elaboration of flue-gas desulfurization and emission limits of sulphur dioxide. Thesis is divided into three parts. First part is about content of sulphur in fuel, formation of sulphur oxides and their influence on human health and environment. Second part is dedicated to sources of sulphur dioxide, present emission situation in the Czech Republic and emission limits of sulphur dioxide. The third part describes methods how to reduce emissions of sulphur dioxide, especially methods of flue-gas desulfurization. The thesis is based on technical texts, Czech laws about air pollution and data from the Czech hydrometeorological institute.

NOx production and elimination content in the flue gas
Čech, Jaroslav ; Šnajdárek, Ladislav (referee) ; Hrnčířová, Michaela (advisor)
The Bachelor thesis deals with oxides of nitrogen, resulting from the combustion process. The thesis is concentrated mainly on the description of the emergence mechanisms and on the various measures that are used to reduce their concentration. Part of the thesis is also focusing on legislation in the field of air protection, with the values of the emission limits valid for the Czech Republic and the European Union.

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.

Effects of decreasing water requirements at wastewater treatment plant
Benešová, Irena ; Raček, Jakub (referee) ; Hluštík, Petr (advisor)
Bachelard thesis si aimed on impact and consequences of decreasing water consumption on wastewater treatment plant. The thesis concerns with water consumption in the Czech republic and generally in the world, while particular attention is payed to the hygienic minimum of water supplies to citizens; the causes of decrease of water consumption and its consequent impacts on wastewater treatment plant are mentioned, and further is discussed design of both present and new wastewater treatment plants. The thesis compares different existing approaches to indicate the specific need of water for technological objects of wastewater treatment plants. Part of the thesis was survey on water consumption, possibilities of water savings, and recyclation of grey water. The overlarge objects of wastewater treatment plant are the result of decreasing water consumption.

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.
