Hodnocení provozu kotle na biomasu z pohledu emisí
Zbojková, Monika
This thesis is aimed to evaluate the biomass combustion boiler service in the emission point of view. There is summarized description and features of biomass energy utilizati-on in termochemical transformations as well as in-the-house use within solving of advantages and disadvantages. In theory part the biomass boiler distribution is descri-bed. The practical part is aimed to monitor and evaluate service modes of biomass boiler in the way of energetic use, individual polutant monitoring especially in the human health and air protection. In the conclusion the municipality use is mentioned.
Využití energie biomasy
Holík, Pavel
This bachelor thesis was written as part of the Bachelor studies at the Faculty of AgriSciences Mendel University in Brno. It deals with the literary solution of the use of energy from biomass. This thesis provides the fundamental summary of energy crops used for energetic processing in the Czech Republic. The selected kinds of biomass are described in detail from their source to the energy production. The technologies of the thermochemical transformations of biomass for energetic purposes and their impact on the environment are closely explained, too. Furthermore, the basic alternatives for home heating and their operational conditions in the future years are described in this Bachelor thesis.
Hodnocení provozu kotle na biomasu
Holík, Pavel
This diploma thesis was written as a part of the master study program at the Faculty of AgriSciences of the Mendel University in Brno. Its main topic is a literary solution and experimental measuring of biomass boiler operations. This thesis provides a basic overview of energy crops for energy use in the Czech Republic. Different technologies of thermo-mechanical transformations of biomass for energy are described in detail. The last part of the thesis focuses on pollutants from biomass burning that were measured in an experimental test.
Research of Progressive Methods for Reduction of Emissions in CI Engine Exhaust Gasses
Franz, Rudolf ; Děrgl, Martin (referee) ; Stodola, Jiří (referee) ; Novotný, Pavel (advisor)
The scope of this dissertation work is a description of modern methods of reducing exhaust emission in diesel engines. The fundamental part is the application of these methods for diesel engines for off-road use that means for engines that are used in tractors and road machines. The mentioned evidence for the practical utility of the results of this dissertation thesis in practice and their verification on the actual engine are given in the conclusion.
Thermal stability of the biomass combustion process
Grygar, Jan ; Špiláček, Michal (referee) ; Poláčik, Ján (advisor)
This bachelor thesis is focused on fne particles, which are produced by small combustion units, and their reduction. The frst chapter deals with the issue of fne particles, their creation, composition and their impact on man and the enviroment. The last chapter deals with the design of solution for reducing of emissions of small biomass combustion units.
Risk of Waste Combustion in Small Boilers
Kopecká, Eliška ; Špiláček, Michal (referee) ; Lisý, Martin (advisor)
The bachelor's thesis deals with the issue of waste combustion in small boilers. In the first chapter, the components of household waste are specified in more detail, as well as the pro-duction and possible waste management. The second chapter is focused on the formation of the pollutants during combustion and their impact on the environment and the human organ-ism. In the third chapter is presented the process of the operation of the waste incinerator and there are mentioned the limit values of the emissions that are released into the air. The fourth chapter deals with the reason for the origin and the comparison of the pollutants aris-ing from combustion in small boilers. Materials defined as household waste and pollutants released from them during incineration are described here. In the end, the results of the the-sis are evaluated.
Emissions from the burning of garden waste
Kuznetsova, Oksana ; Poláčik, Ján (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with the issue of production of gaseous and solid pollutants in the incineration of garden waste. The aim was to carry out and evaluate the experiment. During the evaluation, it was found that the incineration of garden waste produces many times more emissions, than the incineration of wood in the boiler. The reason for the high emission concentrations was the fuel composition and the combustion process. Furthermore, fine particles in the range 17.5–532.8 nm were investigated. In the theoretical part, a literary search was created, which was based on Czech and foreign professional literature.
40/5000 Fine particles produced by the stove
Škvařil, Ondřej ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
This master thesis deals with problematics of fine particles produced during combustion in fireplace stoves. The theoretical part is focused on the analysis of the atmosphere, health consequences, solid pollutants, the formation of particles (origin), particle separation and how they are regulated by laws. Theoretical section of the thesis addresses analysis of biomass and its combustion. In the applied section are listed given methods of the particles measuring according to regulations, common errors during measurement and methods of identification of measured fine particles. Then follow specific measurements of the formed very fine particles produced by the SMPS method. Subsequently, the results of the measurement are evaluated and summarized in the conclusion.
Small-scale electrostatic precipitator for domestic wood-burning appliances
Kantor, Tomáš ; Baláš, Marek (referee) ; Brázdil, Marian (advisor)
Master thesis deals with design of electrostatic precipitator for domestic wood-burning appliances. In the opening chapters, principles of electrostatic precipitation are described and a study of existing electrostatic precipitators for domestic combustion devices is made. In the practical part of the thesis, a mathematical model of electrostatic precipitator was created. Based on the mathematical model, electrostatic precipitator was designed and its performance parameters predicted.
Grate Boiler for Wood Chips - 96,4 t/h
Strnad, Ondřej ; Ryšavý, Milan (referee) ; Lisý, Martin (advisor)
This thesis deals with issue of grate boilers. It describes their properties, function principles and usage. The main part of this thesis is design of grate boiler burning biomass with steam output 96.4 tons/hour. Steam temperature and pressure at the output are 490 °C and 8.1 MPa.
