Design of heat exchanger for heating and humidification of combustion air
Pollach, Ondřej ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
The diploma thesis‘ goal is to design shell and tube combustion air preheater for biomass boiler. The diploma thesis also includes the research of the effect of flue gas condensation on boilers power increase. The first part of the diploma thesis is theoretical introduction about types of air preheaters, options of air moisturing and effect of flue gas condensation on boiler. Following part describes the thermal calculations and construction design of air preheater as well as the condensing flue gas power increase and power increase due to humidification of combustion air.

Biomass Steam-Boiler
Szabó, Gergely ; Brázdil, Marian (referee) ; Lisý, Martin (advisor)
This bachelor’s thesis is a professional research dealing with a biomass steam boiler. The main aim of the thesis is the description of the structure, the function of individual parts and the regulation of the boiler. The first part of the thesis is devoted to boilers in general, presents their fuels, focuses on solid fuel-fired boilers and describes the steam generator of boilers. The second part deals with a specific biomass steam boiler, describes its main parts and discusses the regulation circuits of the boiler.

Increasing the energy efficiency of industrial heating plant
Spišák, Lukáš ; Lisý, Martin (referee) ; Kracík, Petr (advisor)
This bachelor thesis consists of two parts. The introductory chapters are devoted to the basic description of cogeneration and trigeneration technologies, focusing on the description of cogeneration units and cooling devices. The second part of the thesis compares two specific ways of using cogeneration units and gas boilers in the CHEMOSVIT ENERGOCHEM a.s. in the town Svit. Subsequently, both variants are evaluated energetically and economically.

Risk of Waste Combustion in Small Boilers
Kopecká, Eliška ; Špiláček, Michal (referee) ; Lisý, Martin (advisor)
The bachelor's thesis deals with the issue of waste combustion in small boilers. In the first chapter, the components of household waste are specified in more detail, as well as the pro-duction and possible waste management. The second chapter is focused on the formation of the pollutants during combustion and their impact on the environment and the human organ-ism. In the third chapter is presented the process of the operation of the waste incinerator and there are mentioned the limit values of the emissions that are released into the air. The fourth chapter deals with the reason for the origin and the comparison of the pollutants aris-ing from combustion in small boilers. Materials defined as household waste and pollutants released from them during incineration are described here. In the end, the results of the the-sis are evaluated.

Energy consumption and energy supply of educational building
Šperka, Radim ; Lisý, Martin (referee) ; Pospíšil, Jiří (advisor)
This thesis deals with the processing of an energy audit of the selected building for daily education. The target of this thesis is an evaluation of the current situation of the building, it means the evaluation of the thermal-technical qualities and energy consuption. For the initial state new measures will be suggested to reduce the energy consuption. One of the measures will be a proposal for an alternative way of supplying of the thermal energy, using the thermal pump. These suggested saving measures will be evaluated, including basic economic analysis.

Steam boiler for biomass and sand 92,5t/h
Špiláček, Michal ; Lisý, Martin (referee) ; Skála, Zdeněk (advisor)
This master’s thesis is dealing with design of steam boiler for wood chips. Wood chips are considered as biomass and so the steam boiler is considerate to enviroment. Main purpose of this work is calculation of size and number of water/steam heating surfaces so the boiler can produce steam with required parametres of temperature, pressure and amount.

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.
