Design of condensate steam turbine
Tota, Lukáš ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
Diploma thesis deals with the design of steam turbine of PBS ENERGO, a.s. company design concept. Condensing turbine is on low steam parameters and of barrel concept. Turbine has two unregulated steam extractions, regulation stage with action blading and seven stages with reaction blading type, which was computed with ca/u method on mean blading diameter. The thesis contains also design of thermic diagram, calculation of axial force on rotor, calculation of steam seals and basic design of longitudinal turbine cross section.

Steam turbine for an industrial CHP plant
Tretera, Michal ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
This diploma thesis deals with the thermodynamic design of a backpressure steam turbine. The mass flow of steam through the turbine is determined based on the required heat output, which is transferred in a heat exchanger at the turbine outlet. The governing stage of the turbine is in form of an impulse stage, with optimization of degree of reaction included. During the optimization, a suitable rotor blade was chosen as well as its size. The governing stage is followed by fifteen stages of reaction blading with the stage loading coefficient in the range of 2,75 to 2,80. The governing stage and the reaction blading both meet the mechanical strength requirements. Balancing piston, sealing system and bearings are also designed. Finally, a turbine characteristic is created as well as a longitudinal section. The designed turbine has a speed of 10 000 rpm. While supplying the required heat output, it has a terminal power output of 5 863,4 kW and a thermodynamic efficiency of 84,69 %.

Condensing Steam Turbine
Žáček, Ondřej ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
The aim of the thesis „Condensing steam turbine“ is design of condensing steam turbine with uncontrolled extractions. The design is made according to assigned parameters. Balancing scheme of the turbine is defined at the beginning of the thesis. Then design of the regulation stage and reaction stages is accomplished. The calculation (thermodynamic and strength) is computed for mentioned two parts. For thermodynamic calculation is used ca/u method. In closing the design of the seal system is made.

Condensing Steam Turbine
Kracík, Petr ; Martinec, Jiří (referee) ; Fiedler, Jan (advisor)
Diploma thesis named Condensing steam turbine deals with heat scheme balancing computation of condensing steam turbine K55 and her design. This turbine with 5 unregulated take-offs and overpressure blading type, is computed with (c_a/u) method in the middle of blading diameter. Regulation degree is chosen with impulse blading and feet cross section is checked on durability. At the end of the thesis turbine consumption characteristic is derived from the zero output up to the nominal output. Integrated part of this thesis is conceptional design of longitudal turbine section.

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.

Steam turbine for SMR
Guliš, Jan ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
This master’s thesis deals with the design of condensing steam turbine for small modular reactor (SMR) with nominal heat power of 250 MW. Steam turbine is designed in two variants. The first variant operates with all the heat power of nuclear reactor. In the second variant the heat power is equally divided into two identical steam turbines so the designed turbine process half of the heat power. In the first part of the paper the haet balance diagrams with low pressure regeneration are proposed. In both cases the turbine has a total of four bleeds. Three bleeds for low pressure heaters and one bleed for degasification system in feed water tank. Both turbines are designed with an impulse stage and reaction blading. Turbine that processes all the heat power is designed without gearbox at nominal rpm of 3000, contains 15 stages and achieves a clamp power of 71,11 MW. Turbine that operates with half of the heat power is designed with a gearbox at nominal rpm of 4500, has 14 stages and clamp power of 34,91 MW. The consumption characteristics are created for both of designed steam turbines. Drawing of the turbine section is attached to the thesis.
