The subject of the thesis is condensing steam turbine with the required power of 50MWe and set input and output parameters. The turbine is designed as a two-body turbine. There is also designed balance scheme with reheating, regeneration and air condenser. Subsequently, the thermodynamic calculation for three variations of high pressure part with different speeds is demonstrated. The result is evaluated in terms of calculated efficiency and also in an economic point of view. The output is a selection of the variation with the best parameters. Then the basic dimensioning calculations, the design of the leveling piston and the sealing system follows for this variation. A simplified section of this part is drawn. Finally, the balance scheme is adjusted based on the data and calculated for limited performance as well.

The aim of this thesis is a draft of a gas steam boiler with steam output of 200 t/h. The first part of the paper provides stoichiometric calculations, then there are calculations of the dew point, boiler efficiency and the amount of gas. After that, calculations and a draft of the combustion chamber are carried out and then heat balances are drafted. In the following text, geometric properties of individual heat exchanging surfaces are drafted. At the end, there are control calculations. This thesis contains a blueprint of the gas steam boiler.

The purpose of this Diploma Thesis was the construction design of the steam boiler for fytomass. For the specified parameters of biomass have been gradually implemented stoichiometric calculations of which are further based calculation of enthalpies of combustion gas. In the next part have been dealt with heat balance of the boiler, the efficiency of the boiler, recirculation of exhaust gases and the temperature of the combustion gases in outlet from fire. Thereinafter, the proposal of particular heat surfaces of steam boiler was solved, so that the resulting number and size correspond to the desired parameters. The parameters are temperature, pressure and the amount of steam.

The diploma works demonstrates the thermodynamic calculation and design of the geometry flow profile of the back-pressure steam turbine for specified inlet and outlet conditions of steam. Next target of the work is to design the drawing of the turbine axial cross section. Structuring of this diploma work calculation is following: - regulating stage thermodynamic calculation - turbine stages calculation - equalizing-balancing piston calculation - entire turbine intrinsic efficiency and power rating determination - basic calculation of gearbox parameters and RENK-type gearbox selection for turbine and generator arrangement

This diploma thesis deals with proposal of the steam boiler on combustion uncontaminated wood. For the specified parameters have been implemented stoichiometric calculations and calculations enthalpy burnt gas. In the next part have been dealt with heat balance of the boiler, the efficiency of the boiler, design of the combustion chamber and calculation of particular rating surfaces. The output parametres are temperature, pressure and the amount of steam.

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.

This thesis deals with the calculation of the boiler on stillage. Nowadays, when there's fossil fuels are just biomass seems adequate compensation. The great advantage of biomass boilers is a small amount of emissions, especially the greenhouse gas CO2. Of a given fuel composition is made thermal calculation and dimensioning of heat transfer surfaces of steam boilers. The resulting calculation must follow the parameters of steam at the outlet from the boiler.

The diploma thesis concentrates on a project of condensing steam turbine with uncontrolled extraction. These topics are analyzed in more detail: design of thermal diagram, thermodynamic calculation and turbine design concepts. First two topics are solved in the calculation section of the thesis. In the construction part are processed a third topic.

In this master’s thesis, I made a thermodynamic calculation of a steam turbine under the parameters given. In order to increase the efficiency of the low-pressure turbine section and to reduce axial length of the low-pressure rotor, a radial stage is designed in this section. The master’s thesis also includes a design of the low-pressure section. The thesis is divided into chapters, which contains a calculation of the single sections of the turbine. In the introductory chapters, the single sections of the turbine engineered are theoretically discussed. In the conclusion, assessments of the benefits of the use of radial stage are made.

This project was elaborated under the graduate major program 2307 of masters engineering studies. It presents a proposal of anticorrosive protection of steam turbines rotors surface. Based on a literature recherché on automated welding and surfacing under flux, an optimized technology of surfacing of anticorrosive and antierosive layers at output parts of low-pressure sections of rotors will be presented. The optimization of the welding technology will be performed to minimize the possibility of hidden cracks due to application of anticorrosive protective surface and will be evaluated on test samples provided by the company SIEMENS.
