Steam turbine for biomass heating plant
Cmajdálka, Ondřej ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
This master thesis deals with the design of a condensing steam turbine for a biomass block burning wood chips with one regulated take for a hot water heat exchanger. The temperature gradient for the hot water is 90/110 ° C. The thesis guides through the designing proces of a steam turbine from the thermal scheme proposed according to the specified parameters, through the design of the regulatory stage and the stage part of the turbine, including strength calculation, to the design of the compensating piston, seals system and bearings. Finally, the operating characteristic of the turbine is constructed.

Steam Turbine for the Waste to Energy
Janata, Petr ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
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.
