Biomass gasification
Kubík, Michal ; Špiláček, Michal (referee) ; Baláš, Marek (advisor)
This bachelor’s thesis deals with biomass gasification technology. The introductory part is dedicated to biomass, its division and basic ways of its processing. The main part deals with gasification itself, describes individual processes of gasification and describes different types of gasifiers in detail. This thesis deals with synthetic gas, its impurities and ways of their removal. In the last section the brief description of selected use of gasification technology in Czech republic and Europe is made.

Heat sources for home heating
Drga, Pavel ; Špiláček, Michal (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with various heat sources for heating the family house. The first part of the thesis is a research, where the history of heating is summarized, energy sources and types of heating systems are divided and then traditional and unconventional heat sources used in domestic heating are compared. In the second part of this work are made designs of heat sources for heating a specific house. And in the end of the work is made an economic evaluation of the designs.

Assessment of the measure reducing heat loss residential building
Vašíř, Jan ; Chýlek, Radomír (referee) ; Baláš, Marek (advisor)
Objectives of this thesis are analysis of measurements to decrease energetical consumption of buildings and efficiency calculation of measurements made to concrete apartment building. Thesis is thematically devieded into for parts. First part is theory determinating baisic therminology. Heat conduction and its meaning for heat loss in houses is described in this part. In second part is described meaning of thermal insulation and contains analysis of market with materials including suitability of materials for thermal insulation and windows. In third part is described house which is examined in the thesis. Last fourth part contains calculation consumption of heat and examines why was not fulfiled assuption of designed savings. Financial calculation of how much money was saved and when the investmen was retruned. In this part is also estimated mass of CO2 gas emited by thermaly insulated house versus state in which house is not thermly insulated.

New generation of biofuels
Pražák, Vojtěch ; Lisá, Hana (referee) ; Baláš, Marek (advisor)
This bachelor's thesis deals with different generations of biofuels. Their advantages and disadvantages and problems associated with their use in practice. The first part of the theses focuses on legislation and acquaintance with the issue of biofuels as a whole. The second part is focused on acquaintance and description of individual biofuels with examples of use in practice. At the end of the work there is an analysis of individual generations, representation in the fuel market and their efficiency.

Thermal biomass treatment
Křepela, Petr ; Šnajdárek, Ladislav (referee) ; Baláš, Marek (advisor)
The aim of this work is to provide an overview of biomass processing methods, description of final products and their practical application. Furthermore, a description of the technologies used for each method and the comparison of the efficiency. To achieve these goals, it is necessary to carry out a literature search and to produce a comprehensive set of meaningful information that is comprehensible to every reader, but does not hurt the professional public.

Heat exchanger conversion for new media
Guliš, Jan ; Toman, Filip (referee) ; Baláš, Marek (advisor)
This thesis deals with calculation of the existing tube heat exchanger conversion for new media air-water. The theoretical part is devoted to the introduction to the topic of heat exchangers and deals with their basic divisions including descriptions of various types of design. The heat and hydraulic calculation for usage of new media is processed in the second part. The conclusion of the thesis is the result evaluation and proposal of the heat exchanger modifications which could lead to higher efficiency. The thesis includes an appendix with technical documentation of heat exchanger.

Impact of Fuel Moisture on Parameters of Boiler Regulation
Kiša, Michal ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
The work deals with the verification of functionality of moisture content sensors MCT460-WP from the company Process sensors to measure fuel and products from biomass. The sensor is located on one of the Vyncke company boilers. In the first part of thesis are introduced basic issues of biomass. Thesis also generally describes the control and dynamics behaviour of biomass boilers and the effect of input parameters on the output parameters. The last part deals with comparing and analysing measured values with the calculated values and effects of moisture content changes on the output parameters of the boiler. As the last issue is loaded conceptual design based on on-line moisture sensing and inclusion of auxiliary fuel control into the existing system in order to stabilize the processes in the combustion chamber and output parameters. This should result in lower financial demands during boiler operation.

Design of heating water heat exchanger, capacity 200 MW
Vašíček, Jakub ; Kól, Přemysl (referee) ; Baláš, Marek (advisor)
The thesis is focused on the design proposal of thermal heaters for heating water in heat-exchanger station with a total output of 200 MW. The aim of the work is conceptual design of heat exchangers, thermal and hydraulic design of individual heaters and preview of flow of mass and energy. The outputs of the work are written calculations, design drawing of one heater and design of a heater arrangement in exchanger station. The objectives of the work are filled completely. The work is focused on issues directly related to the actual design of heat exchangers, does not give a general overview of the topic. Thermal calculation is limited to the calculation of heat transfer surfaces for condensation of steam and condensate hypothermia.
