The aim of the thesis is to design a high-speed steam turbine as a small energy source. Steam turbine consists of a high-pressure, a medium-pressure and a low-pressure part with a removable condensing module. High-pressure part is designed to perform a single-stage radial turbine with axial steam outlet. The work also includes the layout of the modules and sections. To design individual parts are used steam table „X-steam“.

The aim of this Diploma thesis is calculating the parameters of the heat balance diagram as well as creating balance sheet for winter and summer operation. In one of the first parts, the reader is acquainted with two P&I diagrams containing main accessories, which are also used in the heat scheme, KKS marking system is used to name the acces-sories. The main part of the thesis consists of a detailed calculation of the heat transfer surface of the condenser with design of the tube bundle including the main dimensions of the condenser. Last but not least, the calculations of the hydraulic losses of condenser are included in the thesis.

This master’s thesis deals with design of a high speed steam turbine with detachable condensation module and integrated gearbox. As a source of energy is used heat waste, which is a result of the diesel engines function. Important options concerning conception of the turbo set are discussed in the master’s thesis. Subsequently, thermodynamic calculations for each module are done. Part of the thesis is also simplified calculation of the integral gearbox. Construction drawings of all modules and of the complete turbo set with electrical generator were created based on thermodynamic calculation.

The Master's thesis is focused on the quality management in Industrial Turbomachinery, a subsidiary company of Siemens. On the basis of a demand from the management and the current state the thesis defines and solves the problem, which is an identification of possible causes of failures in the new technical solution to the locking system which is a part of the last stages of the blade lines on the steam turbine rotor. To solve the problem, the thesis firstly tries to find a suitable method, which is subsequently applied.

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.

The diploma thesis is focused on the production process in custom oriented production according to business-economic criteria, these are the individual components of production costs, production capacity and the completion date. The aim of the practical part of the thesis is to design an optimal production process and to create a mathematical model of the optimization problem. Based on the resulting analyses, a comparison of the new model with the existing one is made and recommendations for the analysed company are performed. The result of this work can be used as a general tool for production optimization for industrial companies operating in custom production. Most of the data used in this work was obtained from the enterprise system, or. by observing and recording the measured values, the data was further evaluated using the Excel spreadsheet.

A high-pressure actuator of regulatory valves of steam turbines is designed in this thesis. The first part of the thesis discusses different types of steam turbines and the alternatives of their regulation. In the second part, one particular arrangment, with directional control valve, double poppet valve and hydraulic curtain, is described. Technical documentation including the conceptual proposal, the choice of individual components and all calculations is the output of this thesis. Drawing documentation of the set and drawing documentation required for the construction of the hydraulic block is attached.

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.

The aim of this Master’s thesis is to design a steam condensing turbine with three bleeds. First, a heat balance of the steam cycle is calculated, followed by thermodynamic and stress calculation of the turbine blading and design of a gland steam system and drain system. A price proposal is suggested for the given steam turbine. In the end, a design drawing of the steam turbine is constructed.

The diploma thesis deals with the topic of the optimization calculation of the mass flow of injection from the condensing pumps of the second degree to the condensate of heating steam, flowing from the system of separation and reheating, with the main goal to achieve the maximum power of the block of the power plant. There is calculation of the secondary circuit of the nuclear power plant in Dukovany before and after the optimization. In the next part, there is calculated growth of electric power of the block, results are drawn in diagrams and technical solution is designed.
