Abstract:
ith one controlled extraction and one uncontrolled extraction, calculation of the flow channel at all stage, design and calculation of the regulation valve and create connection diagram of steam turbine and air cooled condenser. At the beginning of this work is an overview of manufacturers of steam turbines and their unified products. Master thesis was developer with G-Team, a.s. as using calculations and the instructions given in the recommended literature with supporting CFD simulations to determine the loss coefficients and FEA simulations to determine the eigenfrequencies blades.

Abstract:
The diploma thesis is focused on solution of technology optimization of steam turbine rotor blades machining. Main goal is to evaluate machining cost accord-ing to change of tools feedrate speed and proposed production technology. During experimental production was monitored the tool wearing VBB of roughing and finishing mill cutter depending on machining time tA. Further, there was evaluated new technology time saving – two piece production and material consumption. The results of experiment are material cost saving and noticeable time reduction for machining of rotor blade, mainly reduction of non-machine working time.

Abstract:
The Master’s thesis deals with the approaches to the introduction of the principles of lean manufacturing and especially the concept of Just in Time (JIT). It is structurally divided into theoretical and practical part. While the theoretical part focuses on the theory of lean manufacturing and the details about steam turbines, the practical part gradually deals with the introduction of the company, production portfolio, supplier analysis and especially the production process. The practical part ends with the selection of proposals for changes in the production concept, including partial economic evaluations with regard to customer requirements to meet delivery dates, quality and required costs.

Abstract:
This diploma thesis is concerned with the design of the machinery with an extraction steam condensing turbine in Precheza corp. The theoretical part of this thesis describes the energetical situation in the company and the primary consideration about recovery of the heat, released at sulphuric acid production, for electrical power production. There is also presented brief description of the sulphuric acid production and the fundamental principles of the steam production at this process. In the practical part of this thesis there is performed the calculation of the heat-flow diagram of the steam turbine and the calculation of heat and producted electrical power at the basic operational states. There is presented the source code for the calculation of the heat-flow diagram using Matlab software. In the end there is mentioned the economical evaluation of the whole project, using the fundamental economical methods, such as net present value method, or profitability index, including the calculation of the pay-back period.

Abstract:
This thesis deals with a technical economic analysis of the midrange biomass units use. The main output product of the thesis is the computational system based on balance models of cogeneration key nodes. The computational system is suited for cogeneration technologies based on the Rankin steam cycle. The computational system was used for a particular case study calculation focused on a 1 MW biomass boiler extension by an expansion engine (a steam turbine or steam engine).

Abstract:
The subject of this thesis is the design of production technology of the hydraulic cylinder – the part of servomotor of a steam turbine control valve. The main precondition is a perspective technology of manufacturing the component on a single workplace using Siemens NX10 CAM system. The implementation of this work was carried out in cooperation with the Siemen, s.r.o., the branch of Industrial Turbomachinery in Brno. Part of the thesis is a brief introduction to the issue of steam turbines. The main part is devoted to analysis of a selected component in terms of technology, design of the best strategy of production technology and its implementation. The conclusion deals with the technical and economic assessment of the proposal.

Abstract:
This thesis deals with design is condensing steam turbines burning fossil fuels with nominal capacity of the generator of 250 MW with steam reheating and regenerative eight uncontrolled extraction points. The turbine consists of two bodies: a combined high-intermediate pressure section and low pressure parts with dual way outlet down into the water-cooled condenser. Work includes calculating thermal scheme for 100% and 75% capacity, specific heat consumption calculation and design of the flow HP-MP body. Further strength control and basic engineering design of high-medium- work completed by longitudinal section. Achievements are at the end of work compared with work 3a and the conclusion summarizes the advantages and disadvantages of the concept.

Abstract:
The aim of this work is comparison of special form tools for manufacture of grooves in rotor turbine. For this purpose tools are chosen from „A“ and „B“ company. Form milling cutters are confronted both in terms of their characteristic features, manufacturing methods, and time and economy intensity. Furthermore, there is described a possible future way of grooves‘ production through the use of the „C“ ‘s programme. Apart from that, this thesis also involves simple programme for comparing the chosen parameters.
