Methods of removing persistant polutants (dioxins)
Ferdan, Tomáš ; Jecha, David (referee) ; Pařízek, Tomáš (advisor)
The bachelor‘s thesis deals with rise of dioxins in waste-to-energy system in municipal waste incinerator and with technologies for their removal. The thesis speaks commonly about characteristics of dioxins and about their influence on environment and health in the first part. Furthermore are outlined the ways of dioxins production and the emission limits for off-gas. The second part of the bachelor’s thesis includes description of commonly used methods for removing dioxins from off-gas. There are mentioned their main advantages, disadvantages and compared efficiency of individual methods.

Air cooled condenser
Bochníček, Ondřej ; Kracík, Petr (referee) ; Pospíšil, Jiří (advisor)
This master´s thesis deals with an air cooled condenser. The specific attention is focused on the condenser in the Brno´s waste-to-energy plant SAKO. The general process of calculation of the heat transfer coefficient is introduced, which is the base for the calculation of the condenser´s output. This process is later used for the calculation of a specific condenser. A considerable part of the thesis is concentrated on the analysis of behavior of the condenser of SAKO in various conditions from the theoretical point of view and then also in terms of real operation using provided operational data.

SAKO Brno - heat output in CHP
Mazák, Tomáš ; Skála, Zdeněk (referee) ; Fiedler, Jan (advisor)
The purpose of this thesis is to design a solution thermal power outlet of incinerator in hot water for the supply this town of heat. First and foremost are described problems landfill society and their implications on the environment. Next some alternatives of the waste and the burning in incinerators are described too. The thesis describes the history of the first incineration plant in the Czech Republic and its subsequent upgrading of the economical and environmentally friendly waste recovery and modernization of flue gas cleaning. Contribution of the work is then proposed as amendments to equipment and wiring for use of steam for the conversion heat output into hot water. This is essentially a calculation of steam water heaters at the end of the expansion of the steam and the related adjustments to the turbine blading. At the conclusion outlines the basic economic calculation and comparison of profits and investment associated with this implementation compared to implementation, which is now projected. It is a calculation of investment efficiency and its possible repayment due to higher profits from the sale of energy. This work serves only as a basis work for future technical realization and it outlines the appropriateness of this alteration.

Stanovení podílu nebezpečných látek ve směsném komunálním odpadu z krajského města
Bartůňková, Zuzana
The purpose of this thesis is to determine the proportion of hazardous substances in mixed municipal waste from the regional city of Brno. There are the basic concepts and information regarding municipal and hazardous waste defined in the literature review. The results of measurement are evaluated in Ma-terial and Methods section. The amount of hazardous and potentially hazardous additives in mixed municipal waste is also evaluated. Subsequently are proposed options for diversion of dangerous additives from mixed municipal waste. The results of this study indicate the amount of hazardous and potentially hazardous additives in mixed municipal waste per resident per year in Brno.

Analýza možností energetického využití odpadů ve vybraném regionu
Chovanec, Jan
This thesis examines the possibility of using the energy potential of waste produced in Ostrava and its surroundings. The aim of this work is to determine whether it makes sense to build a waste incineration plant with energy usage. The thesis also deals with possibilities of heat utilisation, which is produced by the combustion of municipal waste. In the first part is evaluated quantity and composition of the produced waste. The methods of deliveries and the amounts of thermal energy in the selected area are described next. On the base of this information, the facility is designed. Finally, the possible contributions to the region are evaluated.
