Design modification of the collimator for RAW measuring system
Svoboda, Štěpán ; Lisý, Martin (referee) ; Šen, Hugo (advisor)
This thesis deals with structural design of collimator. Collimator is important component of radioactivity measuring device. This apparatus is made by Envinet. Collimator is part of device, which makes good conditions for measuring radioactivity, protects detector and tries avoid overload detector. In this thesis is dealt simplification of collimator. It supposed, that simplified collimator will be more reliable. This proposal saves more money, because company will not have to send employee of Envinet to service their measuring devices in a very distant countries, such as Russia, Ukraine etc.

Aerodynamic Calculation of Air Part of Steam Boiler
Kudela, Libor ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
The aim of this thesis is to realize analysis of problematics of aerodynamic calculations of steam boilers on the part of combustion air. On the basis of project documentation realize evaluations of sectional dissipation factors of each component of inlet tract. Realize calculation of summary pressure (draft) loss. Specify components with highest loss and propose options of their optimization.

Návrh koncepce tepelné elektrárny
Zbořil, David ; Lisý, Martin (referee) ; Milčák, Pavel (advisor)
This diploma thesis deals with the design of a thermal scheme of steam power plant. The introductory part of the thesis is dedicated to theory about thermal power plants, especially those with supercritical steam parameters. In the following parts, there is a design of the thermal scheme of the coal burning power plant. First separate parts, then all interconnected. The last chapter deals with energy and media balance involved in the process.

Design of Steam Generator 13 t/h
Pálka, Jaroslav ; Kraml, Stanislav (referee) ; Lisý, Martin (advisor)
Master's thesis focuses on the design of a steam generator that utilizes superheated steam from a woodchip boiler for heating purposes. The steam generator produces saturated steam with variable parameters that depend on operational requirements. The integration of the steam generator into the thermal circuit is also taken into consideration. The primary objective of this thesis is to conduct through thermal calculations for the steam generator and design the inlets and outlets. In addition, a basic process control system has been designed.

HRSG
Rajkovič, Jaroslav ; Křemínský, Pavel (referee) ; Lisý, Martin (advisor)
The goal of this thesis is to design a two-pressure level heat recovery steam generator. First a general layout of the boiler is selected and thermal calculation is performed. Then the dimensions of flue gas duct are determined and the heat transfer surfaces are designed in detail. After that, the drums and all the main boiler piping are designed a materials selected. Based on the calculated values, a layout drawing and 3D model of the boiler are created.

Study of the difference between natural gas and hydrogen combustion
Winter, Josef ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This thesis deals with the combustion of natural gas with hydrogen in certain volumetric concentrations. The change in physical parameters due to the addition of hydrogen, which differs in its properties from natural gas, was studied. The thesis is divided into a research part, where the properties of natural gas and hydrogen are described, including a comparison with each other, the effects of gas properties on flame, emissions, or temperature. In the second part, a calculation for the fireplace with chosen dimensions was performed and the changes in physical properties due to the addition of hydrogen were observed and the findings are summarized, which will have to be considered in the design of the fireplace. All calculations are added to the appendices.

Effectiveness in reducing costs in heating
Chytil, Michal ; Zlevorová, Tereza (referee) ; Lisý, Martin (advisor)
Heating of family houses, due to its significant energy consumption, ranks among major sources of pollution worldwide and at the same time represents a considerable item in household budgets. This Batchelor thesis deals with the possibilities of saving energy in heating family houses and their economic viability. The thesis includes a list of options for reducing heat loss and subsequent comparison of basic types of heating. At the end there is a model calculation of individual variants and their economic comparison in terms of financial return.

Economic Return on Measures for the Greening of House Heating
Zubek, Tomáš ; Elbl, Patrik (referee) ; Lisý, Martin (advisor)
High and constantly changing energy prices lead us to effort for efficient solutions in the energy aspect of houses. Suitable measures need to be taken to ensure the efficiency of heating in a family house. This work deals with measures to reduce heat losses and the choice of heating sources. Through the right combination, it is possible to reduce the energy demand of a family house and ensure environmentally friendly and cost-effective operation. In the final part of the thesis, individual measures are proposed and evaluated on a model family house. The calculation is performed using the energy calculation program Energie 2023. The main outcome is the financial return of individual measures and their comparison. At the end, the combination of these measures is considered along eith its economic evaluation.
