Appliances for solid fuel for heating
Lackovič, Roman ; Hrnčířová, Michaela (referee) ; Štelcl, Otakar (advisor)
Bachelor's thesis "Appliances for solid fuel for heating" aims on the issue of emission measurement for solid fuel boilers. The first part is a theoretical introduction, where solid fuels are described, following are the types of appliances, which are powered by solid fuels. There are described legislation related to emission limits and principles of devices used for measururing emissions of solid fuel appliances at the end of the theoretical part. The second part is the attention devoted to description of measurement, that we have done, calculation of efficiency and emissions for measurement. Lastly, there is specified emission class to which the boiler, according to measurement, belongs.
Agropellets for House Boilers
Čaňo, Lubomír ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
This bachelor thesis deals with the characteristics of the agropellets and with their combustion in the house combustion units. In the introduction of the first part is described what the agropellets are and how they are produced. It is followed by a characteristics of the agropellets as a fuel and by their comparison to the other solid fuels. The end of the first part is dedicated to a combustion itself and the creation of emissions during it’s combustion. The second part of the bachelor thesis is focused on a practical verification of the characteristics of the selected agropellets as a fuel. It also includes the experimentally measured values of emissions during their combustion.
Impact of Biomass Storing on Heating Value
Černý, Michal ; Špiláček, Michal (referee) ; Lisý, Martin (advisor)
The main aim of my bachelor´s work is the experimental verification of the landfill impact on the parameters biomass. The first part deals with definition, the formation of a basic biomass division. In the next section we find the issues concerning the burning, fuel composition and emissions during combustion. The last part deals with the influence of climatic conditions on the biomass degradation. In the experimental part were measured calorific calorimeter. The result was that, after a measured period of five months to avoid significant degradation of the fuel.
Alternative and hybrid powertrains of cars
Trněný, Pavel ; Ramík, Pavel (referee) ; Píštěk, Václav (advisor)
This bachelor´s thesis deals with alternative fuels for gas engine, hybrid powertrains of cars and finally electric cars. It creates overview in present day used alternative technologies of car powertrains.
Analysis of the Indicators of the DEZA, a. s. Company Using Time Series
Kratochvíl, Bohumír ; Doubravský,, Karel (referee) ; Kropáč, Jiří (advisor)
In his final paper, the author examines and evaluates the statistical indexes of chemical factory DEZA, a. s. that have certain environmental aspects. The analysis itself is based on theoretical findings related to the regressive analysis and time series. Furthermore, the author designed an application in Visual Basic programming language that automatically solves math problems introduced in the final paper. The author also introduces a suggestion on how to improve the company's image.
District heating systems in the Czech Republic in the context of legislative changes
Hylas, Martin ; Poul, David (referee) ; Putna, Ondřej (advisor)
The bachelor thesis focuses on the analysis of the issue of district heating (DH) with regard to legislative changes in the European Union. The first part deals with the analysis of the issue and the evaluation of the state of CZT in the Czech Republic. The European Union's position on climate change, caused by increasing greenhouse gas emissions, which are significantly produced by DH sources, is also discussed. The research part ends with an analysis of possible changes in the heating industry leading to the fulfillment of legislative requirements in the future. The second part of the bachelor's thesis deals with the elaboration of a case study of the change of the fuel mix for the heat source in the existing locality with the use of the technical-economic model. The main goal is to evaluate the usability of renewable resources (biomass, waste) as primary fuels instead of natural gas. The result of the practical part is a comparison of individual variants and changes in the cost of producing 1 GJ of heat compared to the reference variant.
Deployment of electric taxi in real traffic
Koláček, Lukáš ; Imriš, Pavel (referee) ; Šplíchal, Miroslav (advisor)
This master´s thesis is focused on now being developed electric taxi system, which is going to be used for aircraft´s ground movement. The content of this work includes description of this system, requirements and developed solutions, next part describes and evaluate the consequences of deployment such system in real traffic.
Sulfur dioxide emissions
Borýsek, Václav ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with emissions of sulphur oxides. First are described their properties, influence on human health and their impact on the environment. Next thesis deals with present situation of emissions and emission limits. After that selected methods of reduction of sulphur dioxide emissions are described and for representative technology mass balance has been made. Last part describes taken measurements and presents their results.
Verification of the use of agro pellets for heating
Muzikářová, Věra ; Musilová, Petra (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with agropellets and their combustion in terms of emissions and efficiency. It consists of two parts. The first part is theoretical, where the search of available types of biomass, production of agropellets and combustion principle is presented. The second part of the thesis is focused on experimental comparison of efficiency and emission class of boiler for various agropellets.
Solid Particle Emissions from AgroPellets Combustion
Svoboda, Marek ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
This thesis is divided into two parts. The first part deals with defining the main concepts, properties of biomass and pellets. Further, the procedures for measuring agropellets properties according to valid standards are mentioned. The following is a selection of the raw materials for the production of agropellet, with the determination of their properties. The theoretical part closes background research emissions from combustion and emission standards for a solid fuel boiler. The second part is an experimental one, which determines the formation of solid pollutants in combustion of four types of pellets made from alternative sources. Here are the graphs of the gaseous emissions of each of them. At last there will be a comparison of emissions agro pellets with more widespread wood pellets.
