Brown Coal Power Plants in Czech Republic
Šperka, Radim ; Šnajdárek, Ladislav (referee) ; Špiláček, Michal (advisor)
The thesis describes brown-coal power plants in the Czech Republic. The first part discusses brown coal as a mineral raw material, its mining in the Czech Republic, the impact of mining on the environment and ecological territorial limits.. The second part deals with the Thermo-dynamic working cycles in the power plant. Also deals with various technological parts of brown-coal power plant, including equipment and procedures for the cleaning of exhaust gases. The last part describes the most important individual brown-coal power plants in the Czech Republic, their brief history, the technical parameters and the planned service life.

Desulphurisation of flue gas from pulverzided coal boiler,Tp Olomouc
Kozumplík, Ondřej ; Lisý, Martin (referee) ; Skála, Zdeněk (advisor)
The aim of this thesis is to design a desulphurisation device for the pulverized coal boiler K3 in heating plant Olomouc. In this boiler, coal with sulphur content is burnt. Emissions SOx from the boiler output are much higher than the emission limits for SOx, which comes into force 1.1.2016. Therefore it is necessary to build a desulphurisation device, which will cause a significant reduction of SOx emissions and compliance with the emission limits. The thesis consists of two parts - theoretical and practical. The theoretical part states SO2 emission limits and describes various methods for flue gas desulphurisation. In the practical part I chose a semi-dry desulphurisation method with fluid reactor. It determines a stoichiometric amount of combustion air and determines the boiler efficiency. For the required parametres is given a calculation of desulphurisation, the design of some parts of the device and design arrangement.

Desulphurisation of flue gas fuidized bed boiler.
Miklík, Tomáš ; Slezák, Pavel (referee) ; Skála, Zdeněk (advisor)
The aim of this thesis is to design a desulphurization device for the fluid boiler. In the fluid boiler, fuel with extremely high sulphur content is burnt and the combustion products are not desulphurized to the required level, therefore it is necessary to build a desulphurization device. The thesis consists of two parts – theoretical and practical. In the theoretical part I stated the emission limits of sulphur dioxide, elaborated possible desulphurization methods and described the sorbets suitable for desulphurization. In the practical part I chose a dry desulphurization method with fluid reactor, to which a dry sorbent on the basis of lime hydrate is dosed. For the required parameters, I designed the whole desulphurization equipment including cloth filters, all necessary silos and major components. It is a design proposal with a layout and a spatial model.

Výzkum pro hospodaření s odpady v rámci ochrany životního prostředí a udržitelného rozvoje (prevence a minimalizace vzniku odpadů a jejich hodnocení): Výzkum hodnocení výrobků z odpadů a jejich materiálových toků
Výzkumný ústav vodohospodářský T.G. Masaryka, v.v.i., Praha ; Svoboda, Karel ; Sirotková, Dagmar ; Pospíšilová, Eva
Cílem řešení úkolu bylo vybrat odpady na základě údajů informačního systému odpadového hospodářství a materiálů EU, provést laboratorní analýzy vybraných odpadů a posoudit jejich složení a kvalitu, porovnat výsledky analýz s legislativními předpisy ČR a ostatních států EU. Navrhnout přístup k hodnocení výrobků z odpadů, vytvořit přehled firem využívající a zpracovávající vybrané odpady (škvára, struska a kotelní prach, popílek ze spalování uhlí a pevné reakční produkty na bázi vápníku z odsiřování spalin).

Desulphurisation of Waste Gases by Dry Additive Method
Veselý, Václav ; Čech, B.
The molar ratio Ca/S is the most frequently for comparison of efficiency and effectiveness of desulphurisation. Desulphurisation of waste gases by a dry additive method is based on the known fact that calcium oxide with sulphur dioxide and oxygen reacts to stable calcium sulphate at high temperatures (850 up to 950°C).
