Modelling of energy producing system and its operation planning applying advanced mathematical methods
Benáčková, Jana ; Karpíšek, Zdeněk (referee) ; Pavlas, Martin (advisor)
This master's thesis deals with the proposal of the cost-effective biomass and coal combustion concept for a real generation plant. The optimization of the current fuel basis exploitation and annual operation scheduling was the main goal. Applying the regression analysis and stochastic programming the mathematical model was constructed based on the operating data. The overall energy source model was implemented to the concept of the optimal operation scheduling considering the economic aspects. The fuel utilization and energy production planning are the main applications of this design.

Operation check of dredge pump
Pleban, Jakub ; Fiedler, Jan (referee) ; Skála, Zdeněk (advisor)
The aim of this thesis is to consider the operation of dredge pump and design new technology of slag removal including return on investment calculation. The operation optimization itself was preceded by analysis of present technology, data collection, calculation of pressure losses and pinpointing the causes of their origin. Subsequently, the measures to elimination of losses were deduced and these measures were implemented into optimization of dredge pump operation itself. The return on investment into the new technology of slag removal is calculated in the last chapter, considering its feasibility in the heating plant.

Case study on utilizing of heat from the nuclear power plant Dukovany in the district heating system
Kozel, David ; Drbošal, Jan (referee) ; Pospíšil, Jiří (advisor)
In this thesis, I was solved assessment of nuclear power plant Dukovany, conection to the hot water network to city Brno. For determine the size needful enforcement was necessary to establish the heat balance of needs of the city of Brno and the size of the heat supply options. After that it was possible to determine the dimensions of pipes and optimize his routes of due to the current state of land along the route of thermal power supply. Power supply parameters were chosen with regard to the possibilities of technology used for transmission of the media and the status quo for distribution of the city Brno. After pushing the power supply ahead of the city Brno into the pumping station Bosonohy, and second part of the solution was the connection to the backbone wiring SCZT heat to individual customers. The last point was elaborated design management system of heat from nuclear power plant and urban local based resources on current management of heat supply system using consumption diagrams SCZT.

Change of heat source in a heating palnt 2.5 MW
Pikola, Jan ; Pospíšil, Jiří (advisor)
The scope of this Master´s thesis is estimation of changing of heat source in a heating plant 2.5 MW. In the present heating plant burns natural gas, placing of the heating plant makes it possible development source of burning biomass. The scope of thesis is establish with regard to developed capital and operational costs, next effects to environment in scene of heat source, measuring and regulation of technological unit, determination of acceptable size of fuel depot and composition of fuel and ashes economy. The results of this Master´s thesis can be used as a basis about determination toward investment.

Biomass Heating Power Plant
Hrubý, Vojtěch ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
The content of this dissertation is to utilize foundations of heat consumption in Velký Karlov and to propose and replace the main district heating plant into the heating plant which uses biomass as its fuel. With techno-economic evaluation of the annual operating central heating plant evaluate the suitability of using a steam turbine or steam engine. The proposal for a steam turbine is chosen by the preliminary calculation. There are showed suitable possibilities of working and its evaluation considered to return period.

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.

Study of problem solving of IT networks in heating plants in a sphere of activity E.ON CR
Plojhar, Vladimír ; Voříšek, Jiří (advisor) ; Přívozník, Ladislav (referee)
The main goal of this document is to create a comprehensive IT management summary and technological summary concerning the situation in IT and system coverage of E.ON heating plants in the Czech Republic. Real data were used from the Teplárna Tábor a.s. (TTA) and Teplárna Otrokovice a.s. (TOT) heating plants. The first part of this document contains a description and evaluation of the ICT systems of TTA and TOT, data collection management, coverage of IT support for the systems, creation of application architecture for the individual companies and links between the companies. The second part defines the goals and strategies of the companies as well as an evaluation of performance. Performance was evaluated using Gartner Networking Maturity Model methodology. The third part of the document proposes a possible future situation and outlines specific proposals to increase IT performance and stability while respecting the strategic goals of E.ON, the majority owner. The document is concluded with a brief Summary.
