The thesis is focused on designing of backpressure steam turbine to drive the crusher in the sugar factory having the power input of the 2 200 kW. Thermodynamic calculation of two conceptual variations is gradually implemented in the thesis with the aim to determine the steam mass flow through the turbine. In the first version the control stage is selected as an A-wheel and in the second version as a Curtis wheel. The stage part of both versions consists of series action stages. Furthermore, it contains basic design of the gland steam system and the nozzle control system. Both radial and thrust bearings are designed based on the acting forces. The thesis also includes strength calculation of the selected components. The final part deals with comparison and evaluation of the optimal solution. Due to the small difference in rotor weight (m =19,72 kg), and especially for the less steam consumption (M = 4,87 kg/s), the first version can be considered as an optimal solution. This thesis is amended by a mechanical drawing of the turbine cross section on a common frame with a gearbox.

Diploma thesis deals with the design of the condensing steam turbine with power output 23.63 MW at 5000 rpm and an efficiency of 84.17% after optimization. The turbine contains one controlled steam extraction and four bleeds. The steam mass flow required by controlled steam extraction is 0-75 t/h of a total mass flow to the turbine 105 t/h. Design of the steam turbine is preceded by calculation of heat balance of the cycle. Then the thermodynamic and strength calculation of regulation stage and reaction staging flow channel are made. Thermodynamic calculation of the flow channel consists of preliminary and detailed calculation. It is detailed calculation that leads to the turbine parameters optimization. The design also includes gland sealing system and balance piston calculation. In addition to the strength calculation there is bearings load calculation included. In the end, the consumption diagram is made, showing the interval by which the turbine can be safely operated. Integrated part of the thesis is conceptual drawing of steam turbine section.

The aim of this diploma thesis is a design of a condensing steam turbine based on technical specification of inlet steam - maximal mass flow 120 t/h, temperature 440 °C; on temperature in deaerator 125 °C; on mass flow 0 – 60 t/h and pressure 3,0 bar(a) of regulated steam extraction and on ambient temperature in the vicinity 25 °C. The result contains steam turbine with reaction blading, work output 28,76 MWe and efficiency 82 %.

Topic of this diploma thesis is thermodynamical recalculation of turbine TG3 for different parameters and new design of its blading. Introduction deals with theoretical basics of turbines and their components. Second part explains general reasons for retrofit and then specifically for Heating plant Olomouc, where TG3 is located. Third part includes used calculating methods and formulas. Last part presents results, which were calculated in software MS Excel. A cross section drawing is attachment of this thesis.

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

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.

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.

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.
