The Diploma Thesis deals with a design of a backpressure turbine without any bleeds. The fundament of the Diploma Thesis is a thermodynamical calculation of particular parts of the turbine. Technical solutions are designed according to given details of a steam and chosen conditions of use.

The thesis deals with the design of the steam turbine for a waste incinerator. First, the concept and design of the machine is discussed. Following part is the steam turbine thermodynamics calculation, which is the main part of the thesis. My work also contains calculation of axial force and a simplified calculation of the gearbox. The design sections of individual modules and drawing of a disposition of a steam turbine are made on the based of the calculation.

The topic of this diploma thesis is a condensing steam turbine with one regulated steam extraction. The first part contents design and balance of heat scheme. The heat scheme is the basis for the main part of this work, which is the thermodynamic design of the turbine with reaction blades. At the end, the characteristics of the turbine are created. Drawing of the turbine section is attached to this thesis.

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.

The thesis deals with the design of a small-volume four-stroke internal combustion engine with a maximum displacement of 10 cc and a power of 1 kW for autonomous devices of smaller dimensions. In addition to the analysis of individual propulsions for small aircraft, there is also a chapter with the comparison of an internal combustion engine and an electric motor with similar power. Another part of the work is the creation of a thermodynamic model in the GT Power program and its subsequent optimization to increase the overall efficiency of the engine.

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 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.

The diploma thesis concentrates on a project of backpreassure steam turbine. These topics are analyzed in more detail: design of balance schema, thermodynamic calculation, loss coefficient and its effect on the loss. Technical solutions are designed according to given details of a steam and chosen conditions of use.

The diploma thesis deals with preliminary design of condensing steam turbine with three unregulated steam outputs and its gland steam system particularly its description and design. The steam parameters in key outputs were determined in heat balance. The gland steam system parameters were calculated for different operating conditions. It also describes influence of pressure on performance of turbine in gland steam system. Finally, the inquiry sheet for gland steam system device was created based on calculated values.
