Biomass utilization for cogeneration small power
Neminář, Štěpán ; Škorpík, Jiří (referee) ; Baláš, Marek (advisor)
The subject of this thesis is the utilization of biomass for cogeneration units of small power (to 500 kWe). Within the first paragraphs the thesis focuses on technologies which produce more valuable fuels than the solid biomass. This chapter also describes the most recent processes of waste biomass usage. The following section summarizes gaseous and liquid products of this procedure and their feasible use in co-generation. In the last part of this thesis author describes a CHP devices which are used in small electric power production and assesses their advantages and disadvantages. Consequently, some options of their practical usage are highlighted. As a conclusion, these devices are compared and their possible future application is illustrated.

Application of cogeneration units in apartment buildings and industrial buildings
Pinkoš, Patrik ; Radil, Lukáš (referee) ; Pitron, Jiří (advisor)
This bachelor’s thesis deals with issues of cogeneration and its application to apartment buildings and Industrial buildings. At the beginning of the thesis are described main principles. In the next part are characterized different types of cogeneration technologies and their comparisons. This thesis also deals with possibilities of use of cogeneration technologies and the input parameters for commissioning. Thesis contains basic European and Czech legislation for combined production of electricity and heat. At the end thesis deals with possibilities of using cogeneration as decentralized source.

Biomass and waste gasification and cogeneration by the help of microturbine
Kašpar, Matěj ; Najser,, Jan (referee) ; Baláš, Marek (advisor)
This diploma thesis investigate the question of combined production of heat and power by the gasification of biomass. The introduction describes basic dilemma energy conversion from biomass. Further, special attention at the gasification technology and it´s usage at combined heat and power production is paid. The main section includes schematic proposal cycle with use of microturbine 80 [kWe] as well as basic calculation, which serves as a base for folowing project optimization. For discussed optimization is made concept of configuration, thermal and aerodynamics calculation for both heat exchangers B1 and B2. Last but not least these heat exangers were compared by different aspects such as influence of deposits on power transfer and pressure loss. At the end of the work calculated numeric values are discussed and the project of heat exchanger with it´s advantages for practise are summarised.
