Condensing Steam Turbine C55
Božek, Michal ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
The main aim of this diploma thesis is design and calculation of steam condensing turbine with given parameters. In the first part is made calculation of heat balance scheme, which contains high and low pressure regeneration and turbine with total of 5 unregulated steam extraction. It is followed by calculation of regulating stage with impulse blading and calculation of stage part of turbine with reaction blades with total of 27 stages divided to 7 cones. Designes of regulating stage and stage part were checked by calculation of tensile and bending stress. In next parts are calculations of compensating piston and turbine seal system, design of radial and thrust bearings and in the last chapter is shown consumption characteristics of turbine. The designed turbine after optimization at nominal condition has power of 55013,02 kW with thermodynamic efficiency of 83,06 %. The reheat factor of turbine is 1,063. The diploma thesis is supplemented by a conceptual sectional drawing of turbine.

Condensing steam turbine
Prinz, František ; Škorpík, Jiří (referee) ; Kracík, Petr (advisor)
The main topic of this master thesis is the design of condensing steam turbine. In the beginning the heat scheme with low pressure regeneration is calculated. There are chosen 2 low pressure heat exchangers and 3 steam outlets from the turbine. In the main part the thermodynamic proposal with reaction blades is designed, which consists of the regulating stage and the stage part of turbine. The survivability of the turbine is checked by the calculation of mechanical strength. In the end the turbine is checked at reduced mass flow and the turbine characteristic is plotted. The designed steam turbined has a regulating stage and 34 stages in the stage part, has a power of 45873 kW with thermodynamic efficiency of 83.6%. The reheat factor is 1.052.
