Cogeneration in units for thermal processing of biomass and waste
Uhmann, Petr ; Šomplák, Radovan (referee) ; Pavlas, Martin (advisor)
The diploma thesis deals with the cogeneration in units for thermal processing of biomass and waste. The theoretical part deals with the description of biomass and waste and energy recovery from these sources. In theoretical part is also focused on cogeneration and description of computational models of steam turbines. The practical part is focused on a specific calculation of the three steam turbines and comparison of computational models. On the base of the results is designed implementation of computational models to the simulation software W2E.

Condensing Steam Turbine
Víšková, Jaroslava ; Ing.Václav Urbánek (referee) ; Fiedler, Jan (advisor)
The theme of this master thesis is one body steam turbine of 150MW with reheat. There is calculated heat balance of the system with three low pressure heaters, deaerator and two high pressure heaters. Next part deals with calculation of blades and its lenght. Next are the attachments of blades into stator and rotor parts of the turbine. By the end of the thesis there is recalculation of heat balance scheme and blading followed by calculation of parameters for operation of turbine in 75% and 50% of the rated power output. The output of the whole thesis is drawing of horizontal cut of the turbine.

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.

Steam turbine
Šamalík, Jakub ; Martinec, Jiří (referee) ; Fiedler, Jan (advisor)
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.

Steam turbine
Sedlák, Pavel ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
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.

Last stage steam turbine
Šabacký, Filip ; Brettschneider, Bohuslav (referee) ; Fiedler, Jan (advisor)
This Master’s thesis deals with a pre-calculation of a steam condensation turbine on a blading mid diameter. The governing stage is solved as a A-turbine wheel, impulse blading. Multistage blading is solved as a reacion stage by ca/u method. Further, detailed calculation of last stage with a twisted blade is made. Thesis contains comparision of obtained results with a results provided by contracting company. Final part of thesis deals with a design of sectional shape of a turbine blade.

Biomass Heating Power Plant
Hrubý, Vojtěch ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
The content of this dissertation is to utilize foundations of heat consumption in Velký Karlov and to propose and replace the main district heating plant into the heating plant which uses biomass as its fuel. With techno-economic evaluation of the annual operating central heating plant evaluate the suitability of using a steam turbine or steam engine. The proposal for a steam turbine is chosen by the preliminary calculation. There are showed suitable possibilities of working and its evaluation considered to return period.

Steam turbine
Skoupý, Pavel ; Ing.Duda (referee) ; Fiedler, Jan (advisor)
The master´s thesis concentrates on a project of steam turbine with controlled extraction points destined for a communal waste incineration plant. First, there the history of devices using steam as a moving medium is introduced and than follows the description of computing program, where the calculation was running. The master´s thesis subject consists in the thermodynamic project of turbine vaning, in basic project of gearbox including the check calculations and in technical economic comparison of single shaft and twin shaft constructional design. The design documentation is worked up according to the calculated outcomes and contains longitudinal section of turbine and dispositional turbine and gearbox settlement.
