Application of activated carbon in flue gas treatment process
Navrátil, Petr ; Niesner, Jakub (referee) ; Jedlička, Filip (advisor)
The objective of this bachelor thesis is to explain the problematic of flue gas treatment from the air pollutants mainly by methods using adsorption on activated carbon. There is an introduction to environmental protection, description of selected chemicals, charcoal and description of technologies to remove pollutants in municipal waste incinerators, and finally mention the possibilities of disposal or reuse of a saturated carbon. And finally selection of appropriate methods and design for a specific application.

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.

Waste Incineration II: Flue Gas Cleaning Equipment
Albrecht, Jan ; Juřena, Tomáš (referee) ; Turek, Vojtěch (advisor)
Description of the thermal treatment methods dealing with wastes is a major concern of the present study. Emphasis is placed on equipment and methods for purification of waste gases created in the process of thermal destruction. Considering that the efficiency of flue gas treatment is dependent not only on the activity of flue gas equipment elimination, but is completely dependent on a whole unit of operating incinerators, we can not focus exclusively on the block of flue gas treatment. Therefore, in the study there are given a description and drawings of equipment for thermal processing of waste. First part of this thesis addresses the koncept the concept of "waste", its definition, classification and possibilities for treatment or recovery. The whole thesis is also written with emphasis on current legislation relating to waste and thermal processing.

Využití popílků a škváry ze spaloven odpadů ke stavebním účelům
Blinková, Monika
The aim of this study is to examine the possibilities of using fly ash and slag from municipal waste incinerators in the building industry. In the theoretical part waste incinerator, concrete and its elements are described. The practical part is focused on the description of preparation of concrete blocks into which are added fly ash and slag from an incinerator, and description of the final product size and legislation introducing a new product to the Czech market. Fourteen samples of concrete blocks were created and tested for leaching tests and strength tests. Results of the strength test showed a low value because the samples preparation was not followed by proper technological procedure. Mercury and polycyclic aromatic hydrocarbons have been observed in the leaching test. The leachates were compared with Decree No. 294/2005 Coll. and values met the required limits. Formula clause:I do not agree with the publication of the work in accordance with Directive no. 3 / 2017- Publishing undergraduate theses in order to protect trade secrets of the company in its entirety ie. Both in electronic and printed form to the maximum possible period of 3 years.
