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.

Modular Horizontal Heat Recovery Steam Generator
Primes, Alois ; Nantl, Radomír (referee) ; Lisý, Martin (advisor)
This thesis deals with the design of a Heat Recovery Steam Generator (HRSG). Theintroductory part is devoted to a brief description of the boiler, the specified parametersand the compilation of the temperature profile. The main computational part of thiswork is divided into 6 parts. The first contains preparatory calculations, including thecalculation of boiler eiciency. In the second part, a flue gas duct is designed. This isfollowed by a thermal calculation of the boiler for all heat exchange surfaces. The last 3parts deal with the design of the drum, piping and the loss of boiler draft calculation.

Heat Recovery Steam Generator design
Dlouhá, Kristýna ; Botlík, Petr (referee) ; Milčák, Pavel (advisor)
This master’s thesis deals with the design of a heat recovery steam generator. The introductory part of the thesis is dedicated to waste heat boilers, their division and their utilization in combined cycles gas turbine. In the following chapter, an analysis of the existing combined heat and power plant operation is performed. In the next part of the thesis, the conceptual layout of the new source is designed. Subsequently, the thermal calculation of the boiler is carried out as well as the design of individual heat exchanging surfaces. The sixth chapter deals with the strength calculation of the boiler and the outer piping, chambers and drum are designed here. At the end of the thesis there are described off-design states of the new combined cycle gas turbine.

Heating plant modernization and environmental
Sobotka, Tomáš ; Ing.Vladimír Skula (referee) ; Fiedler, Jan (advisor)
The target of this diploma thesis is design of cogeneration unit with following requirements: • Installation of new unit instead of the old and used up one. • Electric energy supply within Supportive service – fast starts • Greening (replacement of coal with natural gas) At the beginning I deal with the current state of old unit. In the next part there is the design of new technological unit, which consists of design of boilers, gas engines, steam turbines. Final phase of the thesis includes economical analysis focused on setting of financial return.

Design of heat recovery steam generator with two pressure levels
Ptáček, Ondřej ; Křemínský, Pavel (referee) ; Baláš, Marek (advisor)
This diploma thesis deals with proposal of a two-lane vertical boiler using the waste heat after gas turbine. In the first part the heat calculation has been done followed by the arrangement of particular heat exchange surfaces and the drawing of real saw diagram. There are also dimensions of drums, inlet and outlet pipes and transfer pipelines drafted. Furthermore, I have listed the materials that are used for casing the boiler and pipelines. Finally, the boiler loss is calculated and the boiler hydraulic calculation is performed. The supplement contains a boiler drawing.

Design of a combi cycle for heating plant
Rovný, Jan ; Kracík, Petr (referee) ; Milčák, Pavel (advisor)
Nowadays, European power production has to meet requirements than ever before. Environmentally oriented efforts end of coal mining and burning of coal, on which economies of a great number of countries depend. The main objective of these efforts is primarily the production of green energy from renewable energy sources and reduction of dependence on fossil fuels. However, the disadvantage of renewable sources (photovoltaics, wind farms) is their dependence on the weather conditions. As a result, there might be delays in supply of electricity, which must be compensated. One of the solutions is the launch of a combi cycle plant, which has the possibility of almost prompt start-up and electricity production. The combustion of gas and liquid fuels also ensures almost emission-free operation. In addition, thanks to the use of waste heat energy from the gas turbine, it is possible to operate the combi cycle unit with the character of a power plant and as a heating plant. The aim of this thesis is to search for combi cycles and balance calculation of the combi cycle heating plant under given conditions. In the last point, the approximate dimensions of the calculated heating plant are given.

Proposal of horizontal dual-pressure heat recovery steam generator
Slíva, Karel ; Svoboda, Petr (referee) ; Baláš, Marek (advisor)
The focus of this thesis is a proposal of a horizontal dual-pressure heat recovery steam generator. The introductory part includes thermal calculation, as well as a design of the layout and a design of the heat transfer surfaces and the layout of the boiler. Individual chapters are broken down according to the outline of the proposal for the arrangement of the heating surfaces, according to the parameters of the flue gas and steam. The master thesis contains a scheme of a real heat transfer temperature diagram and it also includes the calculation of connecting and downcomer pipes and drums. The final part describes the calculation of the boiler draft loss. The main idea of the thesis is accompanied by the technical documentation of the drawing of the boiler.
