Modern low-emission combustion chamber for jet engines
Mašek, Jakub ; Nastálek, Ondřej (referee) ; Šplíchal, Miroslav (advisor)
Bachelor´s thesis examines modern low-emission combustion chambers for jet engines. It´s foremost aim is to specify construction parameters of low-emission combustion chambers, compare it´s features and comprise the use of these combustors in civil aviation. Thesis deals with reasons of modern low-emission combustion chamber development and estimate future development in the region of aircraft industry. Another aim is to specify legislations of aviation emissions, history of certification standards and organizations, which make and control these limits.

Particle size of solid ash
Lochman, Petr ; Špiláček, Michal (referee) ; Hrnčířová, Michaela (advisor)
This bachelor thesis deals with possible ways of analyzing the size of solid particles of ash and their effect on the environment. The first half is devoted to combustion, ash formation and fuels, which are commonly used for energy production. The second half is devoted to a practical analysis of solid particles of different ash samples and their subsequent evaluation.

Purification of flue-gas desulfurization
Křesťan, Jan ; Špiláček, Michal (referee) ; Hrnčířová, Michaela (advisor)
The aim of this thesis is theoretical elaboration of flue-gas desulfurization and emission limits of sulphur dioxide. Thesis is divided into three parts. First part is about content of sulphur in fuel, formation of sulphur oxides and their influence on human health and environment. Second part is dedicated to sources of sulphur dioxide, present emission situation in the Czech Republic and emission limits of sulphur dioxide. The third part describes methods how to reduce emissions of sulphur dioxide, especially methods of flue-gas desulfurization. The thesis is based on technical texts, Czech laws about air pollution and data from the Czech hydrometeorological institute.

Technology sputtering of flue-gas
Hladík, Petr ; Brázdil, Marian (referee) ; Hrnčířová, Michaela (advisor)
The object of this bachelor’s thesis is to create a research in field of flue gas scrubbing technology. In the first part, there are briefly outlined issues of size and shape of particles present in flue gas after combustion. Next part focuses on basic general characteristics of separators. Main part treats of individual types of separators. Following chapters deal with emission limits in Czech Republic and future development of the field. Thesis is concluded by sample calculation of the cyclone separator.

Positive and negative impact of biomass combustion
Jurek, Roman ; Hrnčířová, Michaela (referee) ; Lisý, Martin (advisor)
This work is a specialized research dealing with biomass burning. It outlines key issues as the actual combustion of biomass and an equally significant influence its production on the environment. The first half is devoted to the definition of biomass, its distribution and impact of biomass production for fuel on the environment. The second half is devoted to the process of combustion and emissions released.

Emissions of solid fuel boilers
Gardavský, Jan ; Moskalík, Jiří (referee) ; Štelcl, Otakar (advisor)
The thesis is divided into two main parts. The first part deals with the distribution of fuels used, the distribution of solid fuel boilers and zoom standards for the assessment of emissions. The second part deals with the measurement and evaluation of boiler Slokov Variant SL 22D. First, we describe the basic calculations of efficiency. After that, it deals with the procedure and results of boilers for solid fuels.
