Mathematical modeling of district heating net
Pařízková, Iva ; Kracík, Petr (referee) ; Pospíšil, Jiří (advisor)
This thesis is focused on creating an iterative model for thermal and hydraulic calculation of heating net in Visual Basic of Application. Flowing medium considered is hot water. Although data for heating network in Brno are recorded in this model, its use for any other heating network is possible. This model allows also calculation of minimal temperature of the source and calculation of heat loss of every consumer. This is very useful when considering, if supplying some of the consumers with the heat from a local source would not be more effective. The second part of this text is aimed to evaluation of different ways how to reduce the heat loss in heat network for source Červený mlýn. Both current situation and possibilities for the future are considered.

Biomass Heating Power Plant Brno-nord
Saňka, Marek ; Skála, Zdeněk (referee) ; Fiedler, Jan (advisor)
The master’s thesis topic is the feasibility study of new biomass source construction in power heating plant Brno-North. The first part is focused on historical and current conditions and future development of heat distributions networks and sources of Brno. The power heating plant operation Brno-North is described in more detail including the current heat scheme of operation and plan for the future development. Next chapters are focused on projection of new biomass source. At first, it is defined heat output, operation range and parameters of the new source based on the data of real needs after the heating network modernization. Afterward, selected conceptual variants of the new source are discussed in more detail and for each of the variants are performed heat balance calculation and assembled heat scheme of operation. At the same time it is processed warehouse management calculation and economic analysis of the project. The final chapter evaluates the technical and economic parameters of variants and recommends the most suitable variant of the project.

Cogeneration
Pawlitko, David ; Brázdil, Marian (referee) ; Kracík, Petr (advisor)
This bachelor’s thesis deals with the issue of cogeneration. At the beginning of the thesis, main principles and application of cogeneration are described. Further, various kinds of production of electricity and heat are introduced including comparison of advantages and disadvantages of concrete technology. Another possibility of primary fuel savings are presented too. Thesis also contains Czech and European legislation related to cogeneration, including some changes which bring for year 2013. At the end, heating industry in Czech Republic with its current problems is mentioned.

Cogeneration
Martinek, Jan ; Šnajdárek, Ladislav (referee) ; Fortelný, Zdeněk (advisor)
This bachelor thesis is intended to handle the issue of cogeneration. There is presented the principle of cogeneration and its benefits. Cogeneration is compared to the separate production of power and heat. This work deals with the storage of electric energy and heat and also deals with used batteries. The next chapter discusses the impact of cogeneration to environment and at the end there are mentioned the main Brno’s cogeneration units and central heat distribution in Brno.

An advancement of heating plants system in Brno
Brabec, Vít ; Lízal, František (referee) ; Jaroš, Michal (advisor)
The content of this bachelor’s thesis is the examination of the advancement of heating plants system in Brno. The first part of the thesis introduces a brief overview of an eighty-year history of heating industry in Brno from the first ideas up to the current state. Next part closely describes the individual plants and the system of centralized heat supply. The last section compares heat supply through steam and hydrothermal pipe-line and its influence on the combined production of heat and electrical energy.

Analysis of the impact of ownership on effective operation of heating plants in the Czech Republic
Fajfr, Tomáš ; Macháč, Jan (advisor) ; Zajíček, Miroslav (referee)
Privatization transformation took place in the Czech Republic at the beginning of the nineties which also highly influenced heating plant industry. Some heating plant companies are in private ownership and some remained or were returned back into ownership of towns and villages. The main hypothesis of the bachelor thesis is that heating plant companies are more effective and are reaching better economic results than companies owned by towns and villages. This hypothesis is confirmed with the aid of statistic method of linear regression. Private heating plant companies have in average higher sales on employee, higher return on equity, higher return on sales and also higher share of investments on total revenue. Minor hypothesis saying that towns heating plant will sell heat energy cheaper was disproved.

IT Innovations in the energy sector
Korych, Jan ; Basl, Josef (advisor) ; Fortinová, Jana (referee)
This thesis focuses on innovation of ICT in the energetics sector, particularly in the heating sector. This topic is discussed in terms of both theory and practice. The main goal of this thesis is to show by the example of specific ICT innovations how to properly prepare them. The theoretical part deals with the comparison academic approaches and the approach of the leading Czech supplier of software solutions. It compares the principle of multidimensionality of MMDIS method and methods of Unicorn ES Powered Company. It also discusses in terms of frequency of academic thesis neglected electricity sector, where it focuses on explaining the specifics of this sector using the experience of the author with projects in the Czech and European energetics. It contains a classification of innovation in the industry, market research of ICT products for energetics and SWOT analysis of heat generation sector. The practical part of the thesis focuses on ICT innovation at C -Energy Bohemia. It contains tender documents for this innovation, and based on that is elaborated a methodological approach for evaluation of the benefits of this innovation for the company. Subsequently there is elaborated a proposal for this innovation covering all dimensions of ICT by MMDIS. The main contribution of this work is thus primarily a comparison of academic approaches with the approaches used in practice , the analysis of the current situation of ICT in less well-known electricity industry and the practical application of academic gained from the study of the real demand for ICT innovation.

The analysis of current status and risks for future development of district heating industry in the Czech Republic
Juříček, Vlastimil ; Loužek, Marek (advisor) ; Hladík, Miroslav (referee)
The goal of the thesis is identification and analysis of key risks for Czech district heating sector with focus on coal availability and impact of the EU regulatory measures. In the Czech Republic district heating sector is an important part of energy industry. It serves heating needs of 1.5 million households and substantial amount of industry needs. Currently the question of possible brown coal shortage is becoming urgent. Dynamically changing regulatory framework generating requirements for additional investments is destabilizing. The sector is defined, its competitiveness is evaluated and further the risks are analyzed. Based on brown coal market analysis it is concluded that the current market situation can be considered as stabilized. In the long term perspective the question of possible lifting of the coal mining limits remains crucial. It is concluded that impacts of the EU regulatory measures can't be objectively evaluated at the moment. But it can be assumed that most of district heating companies will be finally able to meet the requirements.
