Steam Boiler
Skoupý, Jan ; Kól, Přemysl (referee) ; Skála, Zdeněk (advisor)
This thesis is focused on the design of steam boiler like a supplement for cogeneration unit of biogas plant. The main idea is to use a waste heat from the exhaust gasses to produce a technological steam of required parameters. The thesis contains of a calculation an amount of the heat in exhaust gasses and a heat exchange surface. An Aerodynamic loss and a wall thickness of the boilers are verified by strength calculation in the next parts of this thesis. At the end of this thesis are made projection drawings and diagram, which are made of the calculations.
Využití odpadního tepla z bioplynové stanice pro zemědělské účely
DUFEK, Daniel
The bachelor thesis deals with utilization for waste heat, which arises during cooling of cogeneration units of biogas plant. It is a concept for technology which is able to consume some of the waste heat. In this case, it is a proposal for a complete recirculating aquaculture system for African catfish breeding, financial analysis and return of investment.
„Smart cities“ and decentralized production of energy
Opátová, Alexandra ; Kudela, Libor (referee) ; Špiláček, Michal (advisor)
This bachelor thesis describes the principles of decentralized energy sources, together with the advantages or challenges that concern the problem. The first chapter describes the concept of "smart city" and the field of use. There are also described options for modeling of urban areas as a unit. The second chapter focuses on the concept of decentralized power generation and the benefits that such a system can offer. The following chapters deal with cogeneration units and electricity storage options. The last chapter focuses on a issue of integrating decentralized power generation into the grid and compares various mathematical models and possibilities of regulation.
Source for heat production in the Czech Republic
Macek, Robin ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
This bachelor’s thesis deals with sources for heat production in the Czech Republic. The first part is a research part and is about used heating technology in our country. The second part is again research part and describes individually in more detail parts of the heat sources, as boils, turbines, heat exchangers a heat distribution. The next chapter compares advantages and disadvantages of central heat supply and local source of heat, first theoretically and then practically. The last part balances production of the heat and electricity from the point of view of the fuel used and the amount of production over the past 15 years.
Energy saving of large objects
Řehák, Pavel ; Brázdil, Marian (referee) ; Pospíšil, Jiří (advisor)
The aim of this diploma thesis is to evaluate the economical measures using own heat and power production using cogeneration units, use of renewable resources to partially cover the consumption of objects, reduction of thermal losses by evaporation in the outdoor swimming pool and overall increase of waste heat utilization by exchanger heat exchangers from flue gas and heat from waste water.
Kogenerační jednotka mikro výkonu v RD
Pusztai, Radek ; Skalka, Miroslav (referee) ; Ondrůšek, Čestmír (advisor)
Bachelor paper on "Cogenerational unit of micro energy in a single-family house" occupies with analysis of usage and economical effectiveness of cogenerational installation in the single-family house. Results and used material are based on longtime knowledge of leading Czech and world companies and institutions. Paper is structed into two parts.
Use of Cogeneration in Family Houses
Pusztai, Radek ; Mastný, Petr (referee) ; Baxant, Petr (advisor)
In the first part of the thesis is elaborated a general view on the issue of cogeneration - a joint production of heat and electricity. In addition to technical and economic aspects are also mentioned basic modes of operation of cogeneration units. Furthermore, installation conditions in the family house and legislative acts associated with the operation. The next section describes the technical parameters of the unit - TEDOM T7. Subsequently, the work performed calculations of the energy needs of the family house. In the next part there is an economic calculation of the object with reference to other sources of heat.
Design of industrial boiler with cogeneration
Mička, Radek ; Tvarůžek, Martin (referee) ; Křenek, Ladislav (advisor)
The diploma thesis deals with the design of the industrial boiler for biomass, Which deals with the issue of the energy future of combustion of fuels using current power generation - microcogeneration, designed for larger houses or smaller com- panies. The shape of the device is the interconnection of individual functional and technological parts of the boiler, a view of a new product that re ects its function. It uses modern and timeless materials, color and control technology to achieve overall comfort and time savings and service.
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.
Optimization of Flat House Heating
Fodor, Ján ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
This diploma thesis deals with the supply of heat in a particular block of flats in Brno. It deals with supply for heating and for hot water heating. The introduction gives information about the considerated building and also generally, but especially with regard to the current situation with consumption and heat supply. Subsequently, the thesis describes the individual possibilities of obtaining heat. There are mentioned classical heat sources as gas boilers, but also less commonly used as co-generating units or solar collectors. Furthermore, the work is calculating from the technical and economic point of view for heating options chosen by the investor. Finally, the work compares the options from viewpoint of benefits, budgets and returns of possible investments.
