Utilization of Waste Heat from Heating Plant Spitalka
Hromádka, Martin ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
This master’s thesis deals with utilization of waste heat from heating plant Spitalka. The aim of the thesis is to explain the general principle of the operation of the heating plants, respectively the heating circuit, then to describe the operation of heating plant Spitalka and to try to identify possible sources of waste heat. Other goals are to make the calculation of waste heat and to make the proposal for its utilization. The final aim of the thesis was to design technological device for utilization of waste heat and to carry out economic evaluation. The master’s thesis describes the principle of functioning of the heating circuit. It explains the issue of combined heat and power production, the principle of functioning of the main technological elements, but also the ecology of operation or distribution of heat through the district heating. Then there is a description of the heating plant Spitalka. The thesis also deals with the water treatment and the description of the technological circuit from the beginning to the distribution to the customer. Next, the waste heat source is identified as water in a closed cooling circuit. The amount of this heat energy is calculated and suggestions for its possible utilization are made. As an application, there are selected two systems, heating and domestic hot water heating. The heating is made by heat pump. Based on the calculations, a heating system using two heat pumps in a bivalent way of connection was designed. In conclusion, the results of the design of the heating system are summarized and an economic evaluation is carried out.

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.

Heat layout of heating power plant with cogeneration unit 1600kWe
Buřil, Tomáš ; Kól, Přemysl (referee) ; Skála, Zdeněk (advisor)
Main target of this master´s thesis is a projection of a thermal circuit of a heating plant, which uses waste heat of a cogeneration unit with power of 1600 kWe. Electric power of a cogeneration unit is supplemented with an electric power produced from a waste heat. All heat is further used for heating in a warm water heating system. Within this thesis are executed projections of a thermal circuit of a heating plant, choice of particular devices, determination of a thermal power of devices and also determination of conditions of particular heat – transferring substances. Furthermore, design of particular devices is made, mainly for basic dimensions and heat transfer.

Network flow models for waste management
Janošťák, František ; Mrázková, Eva (referee) ; Pavlas, Martin (advisor)
This thesis is devoted to the construction of new waste-to-energy plants in a territory where is already another fossil-fuel power station in operation. The aim is to create a mathematical model and prove that those two devices are able to cooperate effectively using same technology. Exactly assembled model under real operating have characteristics of a mixed integer nonlinear programming. The optimization software GAMS is used for its calculation. The complexity of the model, however, is at a level that solutions in bad initial conditions ends in local optima, or not found at all. This thesis is devoted to the elimination of non-linearity using binary variables and heuristic so the task was solved with acceptable time limits to guarantee an optimal solution.

Electric boiler connection in heat plant for providing ancillary services
Ditrych, Marek ; Příhoda, Martin (referee) ; Wasserbauer, Vojtěch (advisor)
The bachelor thesis deals with using the electric boiler for extension ancillary services in heating plant. The system and support services are described in the thesis, because the ancillary services regulate an energy deflection. The system and ancillary services are described in the thesis. Thanks to these services an energy deflection is regulated. The thesis describes different types of electric boilers and there functions. In the thesis is shown the possible solution of using an electric boiler in heating plant Opatovice. The cable conduction is designed for a power of electric boiler. For this reason, there is calculated the equivalent warming short-circuit current close to the electric boiler.

Project of Backup Power Source for the Heating Plant Červený mlýn
Nagy, Pavel ; Vrána, Michal (referee) ; Jára, Jaroslav (referee) ; Orságová, Jaroslava (advisor)
This thesis describes a design of backup power for heating plant Červený mlýn, Teplárny Brno, a.s. The backup power would be used in case of loss of power from the electricity grid, especially in the case of so-called "blackout". Backup power would supply only necessary systems of this heating plant, such as spinning turbines before stopping, control room power supply and lighting. Particularly designs of accumulator, flywheel and diesel generator are discussed. The main aim is to choose the optimum solution.

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.

Operational and Economical Assessment of New Turbine Installation
Čech, Jan ; Hejda, Lukáš (referee) ; Luňáček, Jiří (advisor)
This diploma thesis deals with the operational and economic assessment of the installation of new TG3 turbines in the Přerov Heating Plant. The beginning of this thesis deals with a brief theoretical introduction of this investment and describes the classical economic evaluation methods and the Monte Carlo method. Subsequently, the investment project was analyzed and inputs for the economic model were created. The economic model was then evaluated using classical methods and Monte Carlo methods, the results are then compared with each other. Based on the results of the economic evaluation, the most efficient variant of the Přerov Heating Plant technology was chosen.
