Substitution for a current source of heat in the industrial area
Novák, Jan ; Fiedler, Jan (referee) ; Lisý, Martin (advisor)
The main aim of the thesis is to design a final draft for the reconstruction of the central heating plant of the industrial complex. The background research outlines a brief description of the development of heating plant industry, boilers and conditions for the selection of a suitable heat source for the particular area. Further, there are listed standard possibilities of heat sources for industrial complex, which does not use heat for technological purposes only, but as well as for heating and warming up of supply water. The finding and presentation section summarize the current energy supply and the design of two variants for conceptual modernization of the boiler plant. According to the annual and daily chart for the need for heat, there are specified required heat outputs, which are supposed to be distributed to the campus network of heating and as well as the fuel consumption. One of the options considers the use of storage tanks. The conclusion compares both suggested options.

Combi -cycle with Diesel Engine and Steam Turbine
Bouše, Richard ; Kubiš, Richard (referee) ; Fiedler, Jan (advisor)
This master’s thesis deals with the possibility of increasing efficiency of energy blocks with combustion engines by the combination of the Sabat and Clausius-Rankine cycle into the combined cycle. In the thesis is briefly described the principle of the function of the auxiliary device, which can increase the efficiency of the combustion engine. This device, which consists of a waste heat boiler and two turbine modules, is designed using calculations. Both turbine modules are prepared with drawing documentation and there are described important structural elements. Each key part of the thesis is given by a brief theory, so the basic theory of combustion engines, waste heat boilers and steam turbine are described.

A proposal of power plant with steam engine.
Peterka, Lubomír ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
The final thesis deals with the heating plant with piston steam engine design according to heat consumption background in the location of Velky Karlov and with the design of a heating scheme including its explicit parameters. Further on it deals with the possibilities of the heating plant output regulation and with the solution of natural gas and biomass heating plant operations aside the heating period.

Cogeneration power plant
Ptáček, Martin ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
This bachelor thesis deals with heat and power supply of the family house, which uses natural gas.The first part reveals cogeneration technology in general, especially cogeneration unit based on gas-engine (internal combustion engine).In the second part, the thesis focuses on energy budget (power-balance sheet) issue. Finally, the third and fourth chapter, deal with particular calculation of usability of cogeneration unit in the small family house. Due to a small final financial difference and large investment costs, with such a low heat and power consumption, this technology is unsuitable for this type of usage.

Utilization of thermal panels to increase the efficiency of the heat pump cooling circuit
Lainka, Pavel ; Fiedler, Jan (referee) ; Pospíšil, Jiří (advisor)
This thesis evaluates the connection of solar collectors with heat pump. The work demonstrates meaningful use of solar collector to increase cooling efficiency of the heat pump. Introduction The work introduces the reader to the issue and describes basic principles of the two main sources of energy used in the system - the heat pump and solar system. Next session is dedicated to analysis and evaluation of the data that was measured during system operation. A comparison of measured COP of the heat pump at two different modes of operation was used for the evaluation - with the help of the solar system and without using the solar system.

Condensing Steam Turbine
Víšková, Jaroslava ; Ing.Václav Urbánek (referee) ; Fiedler, Jan (advisor)
The theme of this master thesis is one body steam turbine of 150MW with reheat. There is calculated heat balance of the system with three low pressure heaters, deaerator and two high pressure heaters. Next part deals with calculation of blades and its lenght. Next are the attachments of blades into stator and rotor parts of the turbine. By the end of the thesis there is recalculation of heat balance scheme and blading followed by calculation of parameters for operation of turbine in 75% and 50% of the rated power output. The output of the whole thesis is drawing of horizontal cut of the turbine.

Power supply of remote object
Ocásek, Adam ; Štelcl, Otakar (referee) ; Fiedler, Jan (advisor)
This bachelor thesis is concerned with the issue of covering energy demands of an object which has not yet been electrified. It approaches the topic from both the side of possible technological solutions and the side of financial aspects of executing these projects and concludes with their analysis and comparison. The chosen solutions are the diesel generator, electric cable connection and photovoltaic panels.

Daily launches steam turbines and their impact on the life of the turbine
Štěpánová, Lenka ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
This thesis concentrates on the problem of steam turbines, which require daily cycling by reason of an unstable nature of the energy source. The first part focuses on the current trends which have caused still increasing demand for steam turbines designed for every day start-ups. There is a description of the steam turbine start-up procedure and the heat transfer theory thanks to which the list of the critical parts of the steam turbine has been selected and with respect to these critical points has been created the draft of technical measures for the turbine. The thesis is finished with an evaluation of the life of the steam turbine casing as one of the critical parts and with a proposal for a calculation of a start-up time of the steam turbine.

Condensing steam turbine
Šikula, František ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
The topic of this thesis is a project of condensing steam turbine, which uses as an energy source heat waste from high output combustion engines. In the first part of the thesis, there is a general overview of different types of combustion engines and their thermodynamic cycles. There are also explained important features, which are essential for running of combustion engines. In the second part, there is a theoretical explanation of steam turbine. The main part of the thesis is a project of condensing steam turbine with an integrated gearbox. At first there are chosen basic conceptions, which influence the project; then there is calculated an algorithm for thermodynamic calculation for each turbine module. At the end, there is conducted a simplified calculation of a gearbox and there is also a calculation of payback period of the designed steam turbine. There are made drawings, which are all base on the previous calculations. There are drawings of sectional views of each unit and there is also a drawing of construction arrangement of steam turbine with a generator.
