Steam-gas turbine for energy storage
Staněk, Štěpán ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
Master thesis discusses the growing need of electric energy storage and its effectivity and capacity. It describes an overview of possible technologies with their advantages and disadvantages. Greater attention is paid to the storage of energy in gas, so-called Power to Gas, which combines the electrolytic production of hydrogen from water and the Sabatier reaction to produce synthetic methane. This technology is introduced in the so-called SIT Brno cycle of Siemens Industrial Turbomachinery company. The main part of the thesis is focused on the description of this cycle and on the calculation of the steam-gas turbine (high-pressure and low pressure module). This thesis describes the methodology of turbine calculation and the composition of the steam gas mixture after combustion of methane. The carbon dioxide formed by combustion in the steam-gas mixture generator was replaced by steam. Part of the diploma thesis are drawings of cross-section of individual turbine modules.

Comparing grades axial steam turbines for various media
Staněk, Štěpán ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
Aim of the thesis is to design a single-stage axial steam turbine with impulse blading type for two different media with identical input parameters at input of stator and pressure behind the impeller. Calculation is made for water steam and organic fluid R134a. Main part of this thesis is termodynamic calculation and its optimalization in order to achieve maximum output and efficiency of the stage for both working fluids. At the end of the thesis an alternative calculation of impeller friction losses is presented.
