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.

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.

This master‘s thesis deals with the design of horizontal heat recovery steam generators (HRSG) with two pressure levels after a combustion turbine. In the introduction part is performed thermal calculation and proposal of a heat transfer surfaces. Furthermore, are suggested dimensions of the drums and pipes for flooding and transferring. The emphasis is placed on the fulfillment the required parameters of steam and flue gas at HRSG outlet. At the end is calculated loss of boiler draft and made technical documentation a drawing of the boiler.

This master‘s thesis deals with design of vertical heat recovery steam generators (HRSG). In the introduction part is performed description and distribution HRSG, thermal calculation, proposal of a heat transfer surfaces and choice of materials. Finally is executed aerodynamic calculation, hydraulic calculation and then are suggested dimensions of the drums. Thesis also includes technical documentation of the boiler.

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.

This theses work is concerned with assessment of transfer line exchanger behind pusher furnace. First part is describing technical characteristic and parametres. The most important part of this theses is thermic calculation of the boiler. Last following part is concerned with suggestions of constructional modifications of heating surface for proper functioning of boiler. These modifications are demonstrated by scheme in the enclosure.

This master’s thesis deals with design of technological system for heating and process steam generation. The source of energy is a cogeneration unit. The thesis is divided into several parts. The first part is design of technological system and description. The second part is realized stoichiometric calculation and the thermal balance of steam boiler. The main part of thesis is design of the waste heat steam boiler. The thermal calculation, aerodynamic calculation, hydraulic calculation and strength calculation were made. The thesis also includes the drawing of designed waste heat steam boiler.
