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.

Aerodynamic Calculation of Air Part of Steam Boiler
Kudela, Libor ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
The aim of this thesis is to realize analysis of problematics of aerodynamic calculations of steam boilers on the part of combustion air. On the basis of project documentation realize evaluations of sectional dissipation factors of each component of inlet tract. Realize calculation of summary pressure (draft) loss. Specify components with highest loss and propose options of their optimization.

Combustion of Solid Fuel in Unsuitable Boilers
Ondrůj, Jakub ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
The aim of this work is to investigate the combustion of various solid fuels and experimentally verify the environmental impacts of combustion of selected solid fuels in inappropriate boilers. The first part of the thesis is focused on the determination of solid fuel burning conditions and the second part describes the basic combustion tests, the comparison of the measured emissions during combustion of selected fuels and the comparison of these results with the valid emission limits.

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.

Alternative Biomass Fuels Properties
Krejčiřík, Jiří ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
This bachelor thesis follows up attributes of alternative fuels made from biomass and burning them in home combustion equipment with taking into account the process of creating emissions of solid pollutants. There can be found definition of solid alternative fuels with descripition of how are they made and also their attributes as fuels in the first chapter of this thesis. In the second part can be found description of burning alternative fuels made from biomass with taking into account the process of creating emissions. The third chapter of this bachelor thesis is focused on experimental testing of fuel attributes of alternative fuels made from biomass. There is also practical test of creating emissions with focus on creating solid pollutants in this part.

Optimizing injections from the condensate pump
Kordiovský, Jan ; Milčák, Pavel (referee) ; Pospíšil, Jiří (advisor)
The diploma thesis deals with the topic of the optimization calculation of the mass flow of injection from the condensing pumps of the second degree to the condensate of heating steam, flowing from the system of separation and reheating, with the main goal to achieve the maximum power of the block of the power plant. There is calculation of the secondary circuit of the nuclear power plant in Dukovany before and after the optimization. In the next part, there is calculated growth of electric power of the block, results are drawn in diagrams and technical solution is designed.

Implementation of Cogeneration Unit in "Smart Heating and Cooling Networks"
Uhrík, Patrik ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
The aim of the Master‘s thesis was to create a computational model for integration of the cogeneration unit into the smart thermal network. For the better use of waste heat from the selected cogeneration unit MOTORGAS MGM250 during the summer period, the absorption circuit was dimensioned and the appropriate trigeneration computational model was formed. In the theoretical part, the function, operation and heat performance of the cogeneration unit as well as the suitability of the connection of the cogeneration unit with the absorption chiller during the summer period were described. In the practical part, the operational data of the Faculty of Mechanical Engineering of the Brno University of Technology and the theoretical performance data from created cogeneration and trigeneration computational models were compared. Based on this comparison, the conclusion about the suitability of use of both computational models was made.

Design of Biogas Cleaning Technology
Šrámek, Zbyněk ; Milčák, Pavel (referee) ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
Thesis aims to design suitable technology for biogas treatment so that its output can be used as a fully equivalent fuel for vehicles. First part introduces reader into an area of biogas treatment. Second part describes in detail chosen method, technology of membrain separation. In third part, current conditions in Czech republic were discussed. Fourth part adresses the aplication of membrane technology into existing biogas station via side-standing reaserch container. The end of the thesis is focused on selection and proper desing of blower, which will be transporting raw biogas from biogas fermenters into research container.
