Hydrodynamic analysis of basic equipment in units for the thermal processing of wastes
Říha, Kamil ; Kilkovský, Bohuslav (referee) ; Pařízek, Tomáš (advisor)
Thermal processing of wastes is a metod, when during combustion occur reduction of wastes till 10% previous volume. The main advantage of this method is possibility to heat utilization for heat and electric production. Through thermic process develops range of pollutants (NOx, CO, SO2, HCl, HF, PCDD/F) that had to be remove from off-gas or reduced to enviromental values in agreement with laws in force [16]. For this purpose are combustion units equip with range of devices for removing this pollutans. The main task of this diploma thesis is selectoin of ctirical device in term of pressure drops. The value of pressure drop stands significant part in proposition of efficiecy off-gas fan. In increase or decrease total pressure drop consumption of electrical energy of off-gas fan is rising or going down. Change of consumption in total classification is projecting in energy utilization rate of waste where is determinate if it stands of energy utilizatoin or just incineration. In first part of diploma thesis are described in detail availability methods of off-gas cleaning where is described their principle, advanteges, disadvatages and comparison of effectivity. In second part of diploma thesis is made example model about influnce technology on value of total pressure drop. There were chosen two technologies for removing dioxins (technology of catalytic filtration REMEDIA and DeNox/DeDiox). For both technologies were made detailed analysis of pressure drops single components of these technologies. Attainment results were compared and rated with one another. For analysis these two methods were designed mathematical process in software Maple 9.5.

Design and realization of a passive UHF RFID liquid level sensor tag
Pařízek, Tomáš ; Polívka, Milan (referee) ; Raida, Zbyněk (advisor)
The project deals with a theoretical design of passive ultra-high frequency radio identification (UHF RFID) tag for the measurement of liquid levels. Liquid level has an influence on the input impedance of an RFID tag antenna. The changes of input impedance have been used to distinguish individual liquid levels. Furthermore, this project presents optimization methods for the highest efficiency of an UHF RFID tag in Matlab and it aims to design a suitable antenna within CST MICROWAVE STUDIO.

Design of technology unit for removal of persistent pollutans for thermal processing of contaminated biomass
Plch, Michal ; Máša, Vítězslav (referee) ; Pařízek, Tomáš (advisor)
The Diploma’s work deals with design to use new methods of cleaning the combustion products for the incinerator of biomass, which guarantees removal of dioxins from the combustion products. Thesis depicts methods of cleaning the combustion products, like ADIOX, using ceramic filters, catalytically filters and methods REMEDIA. Thesis compares constituent methods in terms of effectiveness and according to economic analysis applicable to incinerator of biomass-power output 1 MW. Thesis acquaints with the conception of biomass and with thermic processing, which produces dioxins. Thesis processes using biomass in Czech Republic and plan for using in the future. Thesis processes detailed model of filter using the fabric filters REMEDIA. Suggestion of position of the filter and it is connection to original products line of cleaning the combustion products. Increased pressure loss of the new pipework way and increased consumption of ventilator incinerator is calculated for the new connection. In quest of decreasing the thermal loss of combustion products and in quest of increasing safety of operation is calculated and in quest of increasing safety of operation is calculated proposal of isolation for the filter and pipework. In the end of the thesis is depicted using the technology for decreased amount of dioxins from the fly ash from dioxin filter.

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.

Detached house
Pařízek, Tomáš ; Donaťák, Vladislav (referee) ; Donaťáková, Dagmar (advisor)
The subject of this bachelor thesis is a new building of two-generation family house in the village of Březník. The building is situated in a slightly sloping terrain at the end of the construction of family houses on the outskirts of the village. The house has one underground and two above-ground floors. On the first floor there is i terrace from which acces to the garden is provided by a stand-alone steel staircase. Next to the family house is a wooden shed with a plank roof for two cars. The supporting walls in the underground floor are made of permanent formwork Best and in the above-ground floor of the Porotherm masonry elements. The roof is saddle with Tondach grooved tiles.

3D modeling of process unit
Plch, Michal ; Jecha, David (referee) ; Pařízek, Tomáš (advisor)
The Bachelor’s work deals with the technical design of the mixing reactor which should be a part of the semi-operation assembly line applied with the CMD technology. The CMD technology is used for reduction of dioxins in fly ash. The proposed reactor is designed in 3D program Solidworks with the detailed description of the design. In the work there is the description of the formation of dioxins and their influence on people and environment. In the conclusion there is brief information on methods of measurement of undesirable substance including dioxins and technologies for elimination of dioxins from combustion products and fly ash.

Mini-whip antenna
Pařízek, Tomáš ; Lukeš, Zbyněk (referee) ; Raida, Zbyněk (advisor)
The thesis deals with the impedance matching of electrically very short antennas to the real resistance 50 . The antenna is considered as an input of an emitter follower, which plays the role of the impedance transformer. This follower transforms a large complex input impedance, which is typical for electrically short antennas, to a real output resistance. The output impedance was matched by appropriate matching circuitry to 50 in the frequency band of operation.
