Parní turbína pro pohon kompresoru / Steam Turbine for Compressor Drive

Červenec, Adam January 2019 (has links)
The purpose of the diploma thesis is the design of condensing steam turbine for driving a compressor with mechanical power of 14,5 MW and operating speed 6800 rotations per minute on the compressor clutch. The main part is the thermodynamic calculation of the blade canal, which is verified with strength calculation to meet the requirements of the standart API 612. The next part is a basic design of gland sealing system, including a piston which is leveling the axial force with reusage of steam back to the blade canal. This thesis includes a calculation of axial and radial forces including the choice of suitable bearing, which both support the turbine. In the end there is an operating characteristics and function reliability of rising rotating speed on the total stress of blades.

Parní turbína o výkonu 300 MW / Steam Turbine 300 MW

Veleba, Lukáš January 2018 (has links)
The Diploma thesis named Steam Turbine 300 MW contains the proposal of the Turboset for the steam section of the gas-steam cycle. There is a calculation of the thermal cycle, and a thermodynamic calculation of the combined high pressure - as well as intermediate pressure and low pressure parts. Strength calculation of particular parts and a check of the critical turbine speed follow on from this. This thesis includes a drawing of the cross-section of HP-IP and partial operations. My thesis has been commissioned by Doosan Škoda Power.

Parní turbína pro pohon čerpadla / Steam Turbine for Pump Drive

Bureš, David January 2020 (has links)
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.

Rušič vakua parních turbín / Steam turbine vacuum breaker

Kalivodová, Markéta January 2020 (has links)
In this master’s thesis, a preliminary thermodynamic calculation of the turbine is made. Then, the design and location of the vacuum breaker is devised for this turbine. The aim of the master’s thesis is to calculate a time needed to break the vacuum, ie to determine how long it takes to reach the atmospheric pressure inside the turbine and add-on devices. To verify and improve the accuracy of the calculation there are data measured on real projects used.

Bypassový systém parních turbín / Bypass steam turbine system

Molák, Filip January 2021 (has links)
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.
