The aim of this thesis is design a hotwater boiler for burning natural gas with an output of 60 MW. Boiler works with temperature difference 150 °C / 70 °C. For a given fuel is calculated stoichiometric calculation. The following is the calculation of the heat balance of the boiler including the determinativ of thermal efficiency. The fuel used, the required parameters of hot water and feed water temperature are designed individual convective surfaces and dimensions of the boiler. The boiler design includes drawings.

The master´s thesis is focused on detail calculation of back-pressure steam turbine with reactionary blades, with non-control exctraction line with electrical output 8 MW. Thermodynamic calculation of flow stage (canal) and stress calculation of rotor blade carrier of regulation stage, is carried out in firts part of master´s thesis. Preliminary turbine design and description, is carried out in second part of master´s thesis. Master´s thesis tasks has been created in EKOL spol. s.r.o.

The aim of the thesis „Condensing steam turbine“ is design of condensing steam turbine with uncontrolled extractions. The design is made according to assigned parameters. Balancing scheme of the turbine is defined at the beginning of the thesis. Then design of the regulation stage and reaction stages is accomplished. The calculation (thermodynamic and strength) is computed for mentioned two parts. For thermodynamic calculation is used ca/u method. In closing the design of the seal system is made.

Theme of this master's thesis Comparison of thermal cycle efficiency is aimed on the calculation of thermal schemes of reheating and without reheating for various performances. The calculation is performed using specialized literature. The introduction describes the fundamental thermal cycle used in power plants and Rankine - Clausius cycle. After the initial familiarization with the parameters of Rankine - Clausius cycle follow a section with technical solutions to improve thermal efficiency of Rankine - Clausius thermal cycle. The aim of this work is to identify and compare the thermal efficiency of the thermal cycle with reheating, without reheating and compare them with each other. At the conclusion of this work is shown comparison between two low-pressure regeneration systems.

The aim of the work is the design of a grate boiler of 200 t . h-1 output, which will burn brown coal or wood chips. The work is divided into several parts. First, stoichiometric calculation and the calculations enthalpy of flue gases and air are performed. After calculating the heat balance and loss of the boiler was counted boiler efficiency. The design of individual heating surfaces is proposed and at the end are controlled the overall heat balance of the boiler. The calculation is supplemented by drawings.

Thesis solves problems using the nanotechnology for air filtration in HVAC systems. Main specialization work is air filtration for clean spaces with high classes of purity. For example Hospitals, sophisticated technology service, pharmacy etc. Thesis is devide for three parts. First part contains foundation infromations about theory and making fabrics by nanotechnology. Next I described laws of physics, That were using during the solving filtration´s issues. Goal for second part was making the experiments, which should show abilities and properties nanofilters during the air filtration in real environment HVAC systems. In the end measure part is compare nanofilters with common filters. There is describe nanofiltres behavior and their possibilies during the filtration as well as. In last part I expressed own opinions on air filtration by nanofibers. Opinions were making throught informations, That I found out in the process working on thesis and my experiences in HVAC field. By this facts I did compare for get a better idea. Additionally last part contains summary infomations from previously parts and own vision to development in the future. Goal work isn´t promotion and advertising sorts technologies. Ask is just summary and describe discovered knowledges, considered opinions ensue from measuring, information from the Net and people Who work in nanotechnology field.

This thesis is focused on design of black coal combustion boiler of 160t/h output. It consists of several parts. First, stechiometric calculations and enthalpy of air and gas are made, then heat balance of boiler and the boiler losses are calculated, and also thermal efficiency is determined. In next step, the combustion chamber is designed and its thermal calculation is made. Then, each of heating surfaces are designed, and in the last step overall energy balance of the boiler is checked. The scheme of pressure system and design documentation added.

This thesis discusses of the intake tract four-stroke ignition internal combustion engine and the filling efficiency and opportunities to increase this efficiency and consequently to optimize the course of torque and power at the specified serial engine. 3D model is the last point of this thesis.

This Master´s thesis deals with a thermal calculation and dimensional design of steam boiler for natural gas combustion with respect to the high efficiency of the boiler. It includes stoichiometric calculation and calculation of technical specifications of the boiler. Dimensions of combustion chamber are proposed. The crucial part of this thesis includes thermal calculation of designed heat-exchanging surfaces. The heat balance of the whole boiler is made to verify the results.

The master’s thesis introduces various types of electric motors. Overall, it is divided into 6 chapters, which the first deals with special type of electric motors, namely: permanent magnet DC motor with coreless winding, piezoelectric motor and three phase induction motor with solid rotor. For all of these motors are introduced principles, types, advantages, disadvantages and applications. The second part of thesis deals with perspective types of motors, namely: single phase induction motor and reluctance motor. For all of these motors are introduced principles, types, advantages, disadvantages and applications. The third chapter deals with analysis parameters of single phase induction motor. The analysis is performed on a borrowed motor from ATAS company by measurement and verification using simulation program Ansys Maxwell. The fourth part discusses the possibilities of increasing the effectiveness of borrowed electric motor. The following is chapter five, which deals with increasing the efficiency of the motor by changing metal sheets. Results are verified by simulations with Ansys Maxwell and measurements on sample of electric motor. The last part presents electric motor design with new selected electric sheets with lower specific losses, but also with lower magnetic induction.
