Thermal analysis of fuels
Šrámek, Zbyněk ; Hrnčířová, Michaela (referee) ; Moskalík, Jiří (advisor)
The main goal of this thesis is to introduce the field of thermal analysis as an independent scientific discipline. The first section is mostly informative and introduces into a concept of thermal analysis. The second part describes the most fundamental and essential methods of thermal analysis and the last section is focused on evaluating a real thermogravimetric experiment which deals with biomass sample.

Steam boiler burning fytomass waste
Plot, Rostislav ; Skála, Zdeněk (advisor)
This thesis deals with the calculation of the boiler on stillage. Nowadays, when there's fossil fuels are just biomass seems adequate compensation. The great advantage of biomass boilers is a small amount of emissions, especially the greenhouse gas CO2. Of a given fuel composition is made thermal calculation and dimensioning of heat transfer surfaces of steam boilers. The resulting calculation must follow the parameters of steam at the outlet from the boiler.

Energy balance of biomass heating plant
Žmolík, Václav ; Šen, Hugo (referee) ; Baláš, Marek (advisor)
This thesis deals with a design of a biomass heating plant combinating a Rankin-Clausius cyklus and a CHP unit. The CHP unit fuel is a biogas and the boiler fuel is a wooden chip. The adapted CHP unit regenerates feed-water of the R-C cycles. This design is technicaly and economicalty compared with the Rankin-Clausius cycle without feed-water regeneration by the CHP unit.

Boilers for solid fuel
Zezulka, Patrik ; Kudela, Libor (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with the heating of houses with boilers for solid fuels. Thesis is divided into several parts. In the first part is dealt with most common solid fuels, their characteristics, composition and modifications for house heating. The second part is focused on solid fuel boilers, describes chosen boilers, their operation, their advantages and disadvantages. In the last part is economically assessed the suitability of selected solid fuel boilers for heating the model house.

Biomass use in district heating
Dlouhá, Kristýna ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
This bachelor’s thesis deals with the utilization of biomass in district heating. The introductory part of the thesis is dedicated to biomass, its division and ways of its utilization for energy purposes. The following section describes in more detail each of the technologies for power generation from biomass. In the third part, a few of our energy cogeneration sources are stated, they use previously mentioned technologies. At the end of the thesis there is a statistical overview of the utilization of biomass in district heating in the Czech Republic over the last 10 years.

Alternative pellets production
Janíček, Jakub ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This bachelor thesis contains a review of possible technologies for the production of pellets and briquettes. Emphasis is placed on technology for the treatment of biomass for further use. Easy to biomass use is subject to the homogenization and adjusting to the wood chips, pellets or briquettes. The final part of thesis is concerned with energy and economic balance of a specific production line pellets.

Degradation of Biomass Fuels during Storing
Elbl, Patrik ; Kracík, Petr (referee) ; Lisý, Martin (advisor)
This thesis aims to deal with degradation of biomass fuels during storing. The first part of thesis is dedicated to research study concerning of biomass in general. There are mentioned properties of biomass, separation, issues of combustion and storing. The second part deals with experimental determination of degradation of fuel during storing and weather conditions.

Modernization of biomass heat plant.
Sedlák, Martin ; Fiedler, Jan (referee) ; Fiedler, Jan (referee) ; Skála, Zdeněk (advisor)
The thesis examines the suitability of a CHP project in Bystřice nad Pernštejnem, a small town in Vysočina region, Czech Republic, which is currently supplied by biomass central heating. It reviews situation and availability of renewable energy sources and opportunities for CHP both in the Czech Republic and in Europe, including the context of current global developments. The opening chapters are followed with the renewable energy project for Bystřice nad Pernštejnem itself. The current technology, availability of biomass fuel for a potential future project, and possible development of energy sources in the town are analysed. Three alternative solutions for the CHP plant are suggested, with proposal for the technology and economic analysis, and possible future steps of the town council are discussed.
