Pokročilý výpočtový nástroj pro návrh systému čištění spalin z procesu termického zpracování odpadů / Advanced Computational Tool for Flue Gas Cleaning System Design in Thermal Processing of WasteKropáč, Jiří January 2012 (has links)
The thesis describes the development of a computational tool that allows sophisticated analysis and design of flue gas cleaning technologies for thermal treatment of waste. The assessment of a technological composition of the process in terms of energy consumption, temperature of the flue gas stream and ensuring the fulfilment of emission limits allows estimating the influence of flue gas cleaning system on parameters of an up-to-date waste incinerator. The work is based on an already created computational system. Its output will be integrated into a software system with a user-friendly interface. Creation of the computational system is based on the performed research in the given area. The work presents sets of operational values and relationships describing current technologies used to reduce harmful emissions in the flue gas from thermal treatment of waste.

Středotonážní spalovna odpadů - systém čištění spalin / Incineration plant of middle treatment capacity – flue gas cleaning systemKrejčí, Tomáš January 2015 (has links)
Analysis of the regional energy supply, shows that suitable alternative may be a combination of primary energy sources with the municipal solid waste to energy plant. Starting from the fact that the regional thermal energy needs are characterized by smaller power demand, but relatively significant seasonal fluctuations in heat supply. These factors limit the processing performance of the considered waste to energy plant that could be included in the system of regional energy supply. The aim of the thesis was to propose adequate treatment capacity for regional waste to energy plant and explore alternative solutions in off-gas cleaning for exhaust gases generated during incineration of MSW. The balance sheets of two alternative solutions off gas cleaning are part of the thesis, both in terms of material and energy consumption. Presented evaluation of economic demands alternative arrangement of off gas cleaning includes operating costs and the impact on earnings from energy production.

Absorpční čištění spalin vznikajících spalováním odpadů / Absorption Cleaning of Flue Gases Arising from the Incineration of WastesJecha, David January 2010 (has links)
This doctoral thesis deals with potentials of methods for cleaning of flue gas from pollutants such as acidic components. Wet method of flue gas cleaning is analysed in detail with special focus on elimination of sulphur dioxide (SO2). Introduction presents advantages and disadvantages of thermal processing of waste and production of undesired pollutants. Following parts comprise facts about main pollutants produced from incineration. Legislation providing for emission of gaseous pollutants from incinerators is also given. Chapter concerning methods of pollutants elimination is mostly focused on absorption (wet and/or semidry scrubber) and adsorption methods. Several up-to-date technological procedures are mentioned; they have a multifunctional effect such as elimination of acidic components, heavy metals, polychlorinated dibenzo-p-dioxines and dibenzo-furanes from flue gas using single injection of suspense. Elimination of mercury (Hg) is among the technologies for heavy metal elimination which is described in detail. Main part of the thesis is related to experiments at two-stage flue gas cleaning equipment. Function of this experimental unit is described along with methods for measurement of individual quantities and detailed description of all the equipment and its components. Experimental measurements carried out at this equipment are explicated and assessed. Along with experimental work, the author has created a simulation model of wet flue gas cleaning in ChemCad programme. Particular operational parameters were tested on this model. This thesis contains results of the measurement which provide background for verification of the mathematical model. Further, the balance of heavy metals conducted on the basis of measurements in waste incinerator is displayed. Main contribution of the thesis may be summed up as follows: Author has designed and constructed experimental equipment for two stage flue gas cleaning. He also formed calculation for pressure drop of O-element prototype equipment and for packing column with FLEXIPAC structured packing. He created data file with measurements at the experimental unit. He determined temperature at outlet of a random device where liquid is injected into stream of hot flue gas. He designed a simulation model which is identical with experimental equipment and which usage enabled comparison of measured and calculated data; it also serves as a basis for industrial applications. Last part deals with creation off heavy metals balance in a case industrial waste incinerator.
