Automatic pellets boilers
Bureš, David ; Brázdil, Marian (referee) ; Baláš, Marek (advisor)
The thesis is divided into two main parts. The first one deals with the research study about pellets used as a fuel, and about automatic pellet boilers. The second part describes experimental measurements on the boiler Verner A251.1, followed by calculation of the efficiency and a comparison of emission, using wood pellets of different diameters.

Agropellets Properties
Němeček, David ; Špiláček, Michal (referee) ; Lisý, Martin (advisor)
This thesis solves problems of combustion of agropellets and the advantages and disadvantages, which are connected with their application in combustion devices. In this thesis at first there is divided biomass, where it primarily concentrates on the plant biomass and it constitutes some used types, which are used to a fuel production. In the next part it solves problems of production of pellets, the advantages and disadvantages of this production and the advices for superior pellets. In the final theoretical part it solves combustion of this fuel. It is about properties of pellets, problems of combustion and this work also deals with emissions of combustion agropellets. In the last part the thesis engages in experimental detection of agropellets properties and plant biomass as such and subsequent comparison to wood biomass and tabular values.

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.

Heating and hot water preparation of recreation center
Hakl, Jaroslav ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
Content of this bachelor thesis is heating and hot water preparation of recreation centre in the village Ostužná, district Jeseník. Object have 2 above-ground floors. Ground floor is mainly used to meet people in play room or in common room. First floor is situated six accommodation units with private bathroom and toilet. Technical facilities are situated in ground floor and is consists of boiler room and the adjacent fuel storage. For heating is primary used grasifying boiler. Secondary source for hot water preparation is solar systém, that is supplemented by an electric heater in the absence of sunshine. Heating systém is in horizontal double-pipe version with distributor and collector in each floor. The Individual branches on the distributor and collector connected are sections of a single accommodation unit, that can be individually regulated. Radiators are designed as boards in the VK design.

Optimation and Innovation of Family Houses Heating
Dubnický, Ladislav ; Špiláček, Michal (referee) ; Lisý, Martin (advisor)
The aim of this bachelor thesis is to make a summary of knowledge of today´s modern heating systems for family houses. Each types of systems are compared to each other from economic, operating and ecologic point of view. At the end of the thesis there is a model conversion of energetic costs for specific family house and projection of new heating system.

Pellets production
Janíček, Jakub ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This thesis describes the characteristics, treatment and processing of biomass into a form shaped solid biofuels. It contains an overview of the requirements for pellets quality, possible means of improving the quality of pellets and methods of processing materials in order to achieve the desired quality of pellets. This thesis has shaped economic production of biofuels and shaped the recommendations for the design of pelletizing production line alternative pellets.

Restaurant chalupa
Pavíčková, Kristina ; Šteffek, Libor (referee) ; Ostrý, Milan (advisor)
The main aim of this master’s thesis is to elaborate the project documentation of a new restaurant Chalupa. Building is situated in area of the local camp on the edge of the town called Mořkov. The building has one above-ground floor and a partial basement. On above-ground floor, there are two main parts: restaurant and kitchen. Then there are also private room and sanitary facilities for both customers and staff. The building is designed as a CLT superstructure and has a gable roof. The vertical loadbearing structures and non-loadbearing walls are designed of CLT panels. The horizontal loadbearing structures are designed of reinforced cast-in-place concrete slab. Heating energy is supplied by pellet boiler. Ventilation is provided by air conditioning unit. Shading is provided by external louvers. In the third pard, I am creating the facility management plan for this building. The project and visualizations were carried out in the Autocad program.

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.

Forming of solid pollutants from biomass
Havlínová, Denisa ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This bachelor‘s thesis is divided into two main parts. The first part is research and deals mainly with biomass and pollutants. In this section, we will find a two-dimensional distribution of biomass, a comparison of fuel forms and a discussion of basic pollutants with a focus on solid pollutants. The second part is experimental. It starts with a fuel laboratory, where the water, ash and heat content of the biofuels examined is determined. The following is an investigation of the dependence of the PM formation on the properties of the biomass, which was measured by the measurement of these PM by the filters in the collecting device, while the examined biofuels were gradually burned on the fireplace insert.
