Zneškodňování spalin znečištěných NOx II / Treatment of flue gas polluted by NOx II

Jedlička, Filip January 2009 (has links)
My master’s thesis deals with the problems of NOx abatement that are included in flue gases. The accent is put on combined flue gases treatment throug ceramic candles, where the deposited catalyst enables NOx reduction throug the method of selective catalytic reduction. The main aim of my master’s thesis has been the design of experimental equipment for current removal of gas pollutants (dioxins, VOC and NOx) and fly-ash on catalitic ceramic candle. Design of experimental equipment consisted in the calculation of basic characteristics like pipe diameter, filtration chamber diameter, heater performance etc. During the design it was necessary to build pressure drop model that was split into head loss of ceramic candle and piping system. For the evaluation of experimentally measured data and for description of ongoing catalytic reaction in various operating conditions was made prediction model of catalytical filter. The last chapter deals with planned experimental testings.

Adaptace a dostavba domova důchodců / Adaptation and completion of retirement home

Ulyanov, Roman January 2019 (has links)
The subject of this diploma thesis is the construction of Adaptation and completion of retirement home. The building is located in Otovice, district of Karlovy Vary. The building is divided into two building objects. The first is a single-storey new building with a double-decker connecting neck. The new building serves as an office building and provides 24 hours care. The second building is the existing building in which the rooms are located. The new building is designed in combination with several building materials - monolithic reinforced concrete walls, Porotherm blocks and steel columns and beams. The track construction is designed as a monolithic reinforced concrete slab.

Vliv procesních parametrů zařízení Cyclone na kvalitu keramických skořepin / Influence of Cyclone process parameters on the quality of ceramic shells

Lederer, Vojtěch January 2020 (has links)
Diploma thesis contains introduction into shell drying, its monitoring and influence on shell properties. The thesis works with the Cyclone machine described further. The shell drying process in the machine and experiments are carried out broadening understanding of functions and parameters of rapid drying process. Experiments comparing courses of drying under respective settings of Cyclone and under common drying in air-conditioned room are carried out. Also mechanical properties of commonly dried shells and shells made by the Cyclone machines are compared. The positive effect of the machine on the ultimate strenght of dried shells and positive effect on the drying speed has been confirmed.

Pražák, Pavel January 2015 (has links)
The project has been prepared complete documentation of new building to kindergarten the level of documentation for building construction. The target is to create operational dispositive solution which takes account of everyday operations. The new building is comprised of three sections for ninety children. There is also place for kitchen and dining room. The building is located on the outskirts of Šlapanice. The terrain is sloping. The house is based on the footings of plain concrete, is built from the building system HELUZ and is covered with a flat roof. Built-up area is 927,5 m2.

Obrábění žáruvzdorných keramických materiálů frézováním / On the milling of refractory ceramic materials

Reiter, Milan January 2014 (has links)
Diploma thesis is focused on machining of refractory ceramics materials. The theoretical part describes the division of ceramics materials, their structure, manufacture and properties. This part also contains the division of refractory ceramics. In the second chapter, of ceramics materials are described machining. The latest chapter is focused on analyzing the machinability of ceramics materials R - SLI - K. During the experiment, cutting conditions were changed and cutting forces were checked. Then surface roughness was measured and tool wear was observed.

Kubů, Marek January 2016 (has links)
Diploma thesis contains introduction of a company P-D Refractories CZ a. s., where the manufacture of ceramic chimney liners is. Followed by a description and analysis of the product in the entire production cycle, material and product spectrum. Based on the results of current production is created proposal to streamline the machining technology with a view to increase productivity and reduce defective products, which means determine the material of a tool and the method of machining. The work is finished by technical-economic assessment, where the summary and recommendation of the proposed solution are.

Vliv tloušťky vrstev keramického laminátu na bifurkaci trhliny / Influence of lamine thickness on bifurcation appearance in ceramic laminate

Sorokina, Kristina January 2016 (has links)
Z důvodu rozdílných koeficientů délkové teplotní roztažnosti jednotlivých vrstev vzniká ve vrstvách keramického vrstevnatého kompozitního materiálů reziduální napětí. V průběhu chladnutí vrstevnatého kompozitu ze slinovací teploty jednotlivé vrstvy smršťují různými rychlostmi v závislosti na velikosti koeficientu délkové teplotní roztažnosti. Jestliže jsou tyto vrstvy spolu pevně spojeny vzniká v jednotlivých vrstvách různě velké trvalé zbytkové napětí. Velikost residuálního napětí je dána objemovým podílem obou složek v kompozitu. Tato práce byla zaměřena na přípravu a popis 7-mi a 9-ti vrstevných keramických laminátů složených ze střídajících se vrstev dvou rozdílných materiálů. Keramické lamináty byly připraveny pomocí metody suspenzního lití a elektroforetické depozice. U připravených laminátu byl sledován vznik tzv. hranových trhlin (edge cracks) ve vrstvách obsahujících tlaková zbytková pnutí. Výsledky pozorování přítomnosti hranových trhlin pro různou konfiguraci velikosti zbytkových napětí a tloušťky vrstev byly srovnány s teoretickou předpovědí vytvořenou pomocí parametrického 2D modelu. Vliv vzniklých hranových trhlin na průběh lomu byl studován pomocí 3D rekonstrukce lomového povrchu po ohybové zkoušce připravených vrstevnatých kompozitů.

Polykrystalická keramika transparentní pro viditelné a infračervené vlnové délky / Transparent polycrystalline ceramics at visible and infrared wavelenghts

Veselý, Jan January 2010 (has links)
his thesis deals with preparation of transparent ceramic sheets made out of sub-µm alumina powder. Green bodies are prepared by ultraviolet (UV) curing of UV curable resin containing ceramic powder followed by debinding of organic parts at elevated temperature. High relative density of green bodies is essential for reduction of shrinkage during subsequent sintering process. Therefore high solids loading dispersions containing > 57 vol% ceramic particles are used. To reach transparent behaviour, porosity within the sheets must be reduced completely. Therefore hot isostatic pressing (HIP) is used as a final operation. Finally, light transmission and hardness measurements are presented. Possibilities of making high resolution microstructures using maskless lithography and some suggestions for use of the UV curing technique for production of complex-shaped 3D structures are briefly mentioned.
