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.

The master's thesis describes the design of the steam boiler, which burns biomass with heat output of 6 MW. The required parameters of the steam are a temperature of 300 °C and a pressure of 2,5 MPa. The thesis is gradually devoted to stoichiometric calculations through heat losses and boiler efficiency, to the design of the combustion chambre, heat exchangers and pressure losses. Part of the thesis is drawing documentation of the boiler.

This master’s thesis is focused on the design of electric steam generator for superheated steam. Using heating cartridge is the easiest way how to make a saturated or superheated steam. This device is part of gasification reactor, which is used for experimental purposes. The thesis includes schematic involvement of technology. Technology contains evaporator and superheater. The evaporator is calculated as pool boiling. The superheater is design for steam flowing through heating cartridge bundle. At the end of the thesis are made projection drawings, which are based on the calculations.

This diploma thesis deals with the analysis of the drainage pipeline of the Škoda K 220-44 steam turbine. This turbine is operated in Dukovany Nuclear Power Plant. One part of this work is proposal of corrective measures. The aims of this work include the creation of a search for drainage, steam, erosion corrosion and mapping of defects in long-term operated drainage system. Work also includes the evaluation of measured values of the pipe wall thickness measured by ultrasonic analyzer. In addition, the work contains images created from 3D model, on which the location of defects and measurements are displayed.

The thesis discusses the use of biomass for electricity island operation. The first chapter explains the concept of biomass and its distribution. It also shows the potential and availability of biomass. The second chapter describes the transformation of biomass into a suitable fuel form. The third to fifth chapter describes the conversion of biomass as a fuel into electrical energy through combustion, Stirling and steam engine. In these chapters there are brought the following parameters and prices of these motors and single-phase and three-phase alternators that can be connected to these engines. Other chapters describe the production of electricity in line with consumption, where the cost per hour to run engines for the various types of fuel and price of the electricity produced in kilowatt hours is calculated. In the last chapter of the thesis there is described the possibility of accumulation of electrical energy.

The main purpose of this master’s thesis is description of the current technology of compressed air production in the grounds of Třinecké Železárny, a.s. (TZ). Compressed air for companies in the TZ area is manufactured and distributed by company Energetika Třinec, a.s. (ET). The part of the thesis is the preparation and execution of measurement including evaluation of specific energy consumption for production of compressed air by compressors of ET company. In conclusion there is proposed the possibility of substitution of compressors including the economic evaluation.

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.

Subject of this thesis is design of the steam generator for modular reactor. The dissertation consist of the theoretical part, where are described heat-exchangers and steam generators used in nuclear power plants. Second part contains theoretical calculations in the first approach (thermal, hydraulic and strenght calculation). In the next part are particular variants of steam generator selected. For the final variant are necessary calculations (introduced above) and drawings of selected parts are done. In the final statement is technical solution evaluated, and the parameters of the steam generator are compared with actually used steam generators.

Objective of this Master’s thesis is to make search about generation and use biogas, with focus on cogeneration and to make search about possibilities of increasing the share of production of electricity by cogeneration from biogas. This final work has also the task to summarize possibilities of increasing the share with ORC cycle and to evaluate pros and cons of this use. Main part of this work is dealing with own design of increasing production of electricity with cogeneration from biogas in biogas station with ORC cycle and comparing this modification with steam engine.

This thesis is focused on calculation of double casing condensing steam turbine with capacity 200 MW for petrochemical industry´s consumptions. Engine is projected for gas-steam cycle. It has one controlled extraction points placed between two bodies, two uncontrolled extraction points and axial output to air-cooling condenser. Balance scheme was made for 100% operation. Detail design is made only for ST/NT casing and it includes calculation of flowing part, selection of blade´s profile and its stress control. Rotor is checked for critical speed, safety rigid coupling is calculated and according to reaction forces journal bearing are designed. In the end regulation of turbo-set is discussed more precisely and there are calculation of temperature and pressure in uncontrolled extraction points during 80% and 60% operation. Thesis was written out according to Doosan Skoda Power´s instruction and with their cooperation.
