Modular Horizontal Heat Recovery Steam Generator
Primes, Alois ; Nantl, Radomír (referee) ; Lisý, Martin (advisor)
This thesis deals with the design of a Heat Recovery Steam Generator (HRSG). Theintroductory part is devoted to a brief description of the boiler, the specified parametersand the compilation of the temperature profile. The main computational part of thiswork is divided into 6 parts. The first contains preparatory calculations, including thecalculation of boiler eiciency. In the second part, a flue gas duct is designed. This isfollowed by a thermal calculation of the boiler for all heat exchange surfaces. The last 3parts deal with the design of the drum, piping and the loss of boiler draft calculation.

Project construction management technology unit
Šaroun, Josef ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
The target of this master thesis is specify the requirements, which come up while summing the investment aim of a new 40MW energetic unit, and show the overall project management. Thesis is divided into two parts. First part deals with project management from the investors point of view. There is also detailed concept study, technological description of piston co-generation units and combined cycle, concept design of calculated variations and their economical analysis. Second part is taken from the point of view of the main supplier. There is defined the range of operations, documents and official permissions needed for successful finish of the civil part of the energetic unit project.

Combined heat and power generation
Hlaváč, Ivan ; Zálešák, Martin (referee) ; Klimeš, Lubomír (advisor)
The bachelor thesis deals with the power generation by means of a combined gas-steam cycle. In the first part of the work, an overview and description of the combined cycle as well as of the Brayton cycle and the Rankine cycle are provided. The second part of the work focuses in the thermal analysis of the cycles. As a part of the work, a computer program was created, which allows for such thermal analysis of the combined cycle.

Steam Turbine 300 MW
Veleba, Lukáš ; Kubiš, Zdeněk (referee) ; Fiedler, Jan (advisor)
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.

Expansion Turbine
Hlavinka, Miloslav ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
The content of this bachelor thesis is the analysys of a problem of expansion turbines and their usage in the gas-steam cycle. In the first part the respective parts of the combided cycle are described, Brayton cycle and Rankine-Clausius cycle. The gas-steam cycle is discribed subsequently. In the second part the natural gas is briefly described and how it gets to us. There is described the conventional natural gas reduction station and the conventional process steam reduction station. The main part is a description of the expansion turbine, division of turbines, caluclation of efficiency and a description of steam and natural gas expansion turbine. Then there is a describtion of the steam-gas heating plant Červený mlýn and its parts. As an example of the economic evaluation the replacement of conventional reduction station at heating plant Červený mlýn by expansion turbine is shown.

Steam-gas cycle from a thermodynamic viewpoint
Pransperger, Jan ; Štětina, Josef (referee) ; Jaroš, Michal (advisor)
This thesis deals with thermodynamic of steam-gas cycle and compare that with some others heat cycles. It focuses on efficiency of cycle and its limits in the context of the second thermodynamic low. Also it shortly summarizes some technical solutions and possibilities of the cycle. The mentioned knowledge are applied to concrete example of Brno’s heat and power plant Červený mlýn (Red mill) in the last part and allow assessment of its efficiency.

Increased power microturbines operating in indirect circulation
Polák, Luboš ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
Turbogenerator unit 100B TGU, produced in the First Brno Engineering Velká Bíteš a.s., works in Brayton indirect circulation. The aim of this work is the proposal to increase performance levels of technological unit in which the micro-turbine is applied. The work presents various ways to increase performance and efficiency of circulation. The possible options are compared with each of the technological and economic terms. Based on these criteria was selected variant feeding additional water into the circulation. For this design was the work of a mathematical model based on, which was established as the economic balance of the selected variants. The thesis also proposes a technological scheme, which is already incorporated the selected variant and an outline of the verification tests.

Double Casing Condensing Steam Turbine
Adámek, Tomáš ; Richard, Fichtl (referee) ; Fiedler, Jan (advisor)
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.

Condensation Steam Turbine for Combi-cycle
Pavlíček, Martin ; Ing.Ondřej Štěpánek (referee) ; Fiedler, Jan (advisor)
This thesis named Cosdensing steam turbine in combi-cycle deals with the calculation of thermal balancing scheme and the design of turbine. This double body steam turbine with combined HP-IP part and double-flow LP part does not have any additional samples of technological steam. LP part has two side outputs to the water-cooled condensers. There is a basic calculation of force effects on the LP part at operation. The thesis also includes a drawing of a longitudinal cut of LP part and its layout, including positron of the condensers.
