Type design and flowchart of a steam turbine for a specific location
Kalina, Leoš ; Pospíšil, Jiří (referee) ; Škorpík, Jiří (advisor)
This master's thesis is deals with type designing and implementing the steam turbine to the machine part of heat plant in reconstruction. The thesis consists of two parts. First part is theoretical explanation of the heating industry, steam turbines, thermal cycles and components of thermal power plants. Second part of the thesis describes the design and calculation of thermal diagrams based on turbine parameters, which were provided from Tenza, a.s. tender. There is a simplified calculation of technical-economic study in the conclusion of the thesis. The thesis output is recommendation of single final implementation solution for customer.

Steam Turbine for the Waste to Energy
Gajdoš, Adam ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
Diploma thesis deals with the design of the condensing steam turbine with power output 23.63 MW at 5000 rpm and an efficiency of 84.17% after optimization. The turbine contains one controlled steam extraction and four bleeds. The steam mass flow required by controlled steam extraction is 0-75 t/h of a total mass flow to the turbine 105 t/h. Design of the steam turbine is preceded by calculation of heat balance of the cycle. Then the thermodynamic and strength calculation of regulation stage and reaction staging flow channel are made. Thermodynamic calculation of the flow channel consists of preliminary and detailed calculation. It is detailed calculation that leads to the turbine parameters optimization. The design also includes gland sealing system and balance piston calculation. In addition to the strength calculation there is bearings load calculation included. In the end, the consumption diagram is made, showing the interval by which the turbine can be safely operated. Integrated part of the thesis is conceptual drawing of steam turbine section.

Bypass steam turbine system
Molák, Filip ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
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.

Steam condensing turbine
Štěpánová, Lenka ; Krbek, Jaroslav (referee) ; Fiedler, Jan (advisor)
The aim of this Master’s thesis is to design a steam condensing turbine with three bleeds. First, a heat balance of the steam cycle is calculated, followed by thermodynamic and stress calculation of the turbine blading and design of a gland steam system and drain system. A price proposal is suggested for the given steam turbine. In the end, a design drawing of the steam turbine is constructed.

Comparison of the concept nuclear power plants feedwater heaters
Špaček, Michal ; Kracík, Petr (referee) ; Milčák, Pavel (advisor)
The topic of this master thesis is comparison of the concept nuclear power plants feedwater heaters. At the beginning, a brief recherche is written in which the types of nuclear reactors and the heat regeneration system are described. In the next part of the thesis, the heat balance diagram of the nuclear power plant is proposed and the parameters found in the design are further used for the thermal calculation of the feedwater heater of low and high pressure regeneration. The thermal calculation is performed for both horizontal and vertical designs. Finally, a basic dimensional design is made for both designs and these designs are compared with each other.

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.
