The master thesis deals with the design of a condensing steam turbine for a waste incineration plant with regulated take for a heat exchanger, which has a heat output of 15 MWt and a temperature gradient of 60/90 °C. In the thesis, a thermal scheme was first designed, which was based on the required design parameters. The maximum mass flow of steam into the turbine is 38 t/h. The pressure and temperature of the admission steam is 37 bar and 440 °C. The degassing temperature is 105 °C and the cooling water temperature at the condenser inlet is 20 °C. The following is the design and thermodynamic calculation of the turbine flow channels. The first stage of the turbine is designed as a regulatory with equal pressure blades. The rest part of the turbine is designed with overpressure blades and is divided into 6 cones, in which there are a total of 27 stages. The strength inspection of the designed blade profiles was performed. A compensating piston and a gland system were designed. Finally, bearings for the rotor were designed and then the operating diagram of the turbine was constructed. The work is supplemented by a structural drawing of the longitudinal section of the turbine.

The aim of this diploma thesis is the design of a condensing steam turbine to drive a pump with a mechanical power of 9 MW. Based on the parameters, a thermodynamic design of the flow channel is performed, including the strength control of the blades, taking into account the API 612 standard. To compensate for the forces arising during operation, a thrust bearing and radial bearings are designed. At the end of the computational part of work, the operational characteristics of the turbine are performed. The appendix contains an idea drawing, which shows a section of the turbine.

This diploma thesis deals with the design of a steam condensing turbine for intake steam of pressure 125 bar, temperature 540 °C and maximal intake of steam into the turbine 130 t/h. A thermal scheme is designed, including low-pressure and high-pressure regeneration, an air condenser, a feed tank and a boiler. Afterwards a thermodynamic design of a condensing turbine is made with an A-wheel type regulating stage and a stage part with reaction blades. The design of the blades is strength-tested. Then is made the design of the compensating piston and the sealing system. In the end the characteristics of the turbine for non-design steam flows is plotted. The designed turbine has a power of 34644 kW, has a thermodynamic efficiency of 85.1% and a reheat factor of 1.046.

The aim of the master's thesis is the design of a condensing steam turbine to drive a compressor with specified parameters. Firstly, the thermodynamic calculation of the flow channels is made, which are verified by strength control to meet the API 612 standard. Following, the calculation for the axial and radial bearings, on which the turbine is mounted, is described and the operating characteristic is developed. Finally, a construction drawing of the longitudinal section of the steam turbine is attached.

The main goal of the diploma thesis is to design a new ventilation and heating system in an old house after its reconstruction. The design also includes consideration of the possibility of using renewable resources. A central heat recovery ventilation systém is designed to ensure ventilation of the building. The heating design is based on two independent heat sources. It is a wood boiler and a gas condensing boiler. After considering renewable sources, a photovoltaic system is designed. The results of individual calculations and drawing documentation of designs are also attached.

The master’s thesis deals with the bypass system of steam turbine, especially about its heating during normal operation and cold start up. At the beginning of work, a preliminary thermodynamic calculation of condensing steam turbine with two uncontrolled extractions is made. This is followed by theoretical description and design of bypass system and design of heating during normal operation and cold start-up. The main goal of thesis is optimalization of heating, when the heating branch is connected back to turbine supply line. In the end, all options of heating are compared in terms of power output.

Diploma thesis deals with design and comparison of heating systems. In diploma thesis is designed system with gas condensing boiler, system with heat pump and system with gas condensing boiler for heating and solar collectors for heating of hot water. Content of this thesis is calculation of house heat loss, design of radiators, design of heat systems including a check of protective components, regulation with the help of thermostatic radiator valve, calculation of economical evaluation and creation of design documentation.

In the analysis of costs is considered a usage of natural gas for heating and warming of hot water with a condensing boiler, annual consumption of electric energy for operation of electrical appliances in household, consumption of electric energy for operation of heat pump for heating and warming of hot water and consumption of electric energy for warming of hot water in case of system with solar collectors. In the final evaluation a pay-off period is determined.
