Steam Turbine for Biomass Power Plant
Abrahám, Jan ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
Diploma thesis deals with the design of a condensing steam turbine with one controlled steam extraction. Its working range is 0 to 10 t/h. The first part contains the design of the heat balance scheme. The turbine has two unregulated steam extractions for low-pressure feedwater heater and outlet steam is cooled by water condenser. The main part is the design of the turbine flow channel with one regulative stage using impulse blading and 26 regular stages using reaction blading. The turbine rotating speed is 8500 rpm, which is strength suitable even in critical points. The following chapters are describing the design of the compensation piston and bearings. The consumption characteristic of the steam turbine is shown in the last chapter. Drawing of the turbine section is attached to this thesis. Final turbine power is 9259,7 kW and thermodynamic efficiency 85,5 %.

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.

Retrofit Steam Condensing Turbine
Holečková, Michaela ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
The aim of this master thesis is the retrofit of a condensing steam turbine. The thesis obtains a revision of the steam turbine, the reconstruction of steam turbine blades and the basic calculation of bolt torques of the turbine split plane. The master thesis is assigned to a specific retrofit of the steam turbine Lang. In the introductory part the thesis is focused on the turbine description and the basic functions of selected turbine components. The following part deals with the revision and the proposal of repairs for all components and the recommendation of additional modernizations of specific measuring equipments. The analysis of anchoring the stator and rotor blading and their reconstruction is discussed in the next part. In the last part the thesis focuses on the sealing of the turbine split plane and the calculation of the various bolt torques closely linked to the sealing.

Anticorrosive protection of steam turbines rotors surface
Špičková, Petra ; Kubíček, Jaroslav (referee) ; Daněk, Ladislav (advisor)
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.
