Pre-processing of acquired data for system identification purposes
Horáková, Eva ; Chlápek, Petr (referee) ; Máša, Vítězslav (advisor)
The present bachelor’s thesis follows a methodology of data processing for the experimental system identification. Summarizes basic principles of experimental identification and describes a general methodology of experimental data processing. Next part of thesis attends to describing a building of compact data file, that contains selected variables including calculation of other important variables. Measurements to obtain experimental data was realized on real technology, which is a unit of biomass and phytomass combustion, power of unit is 1 MW. The work also includes selection and evaluation of appropriate intervals for an identification of this unit and their graphic presentation.

Control of heat sources orientated on the biomass combustion
Havlíček, Martin ; Chlápek, Petr (referee) ; Máša, Vítězslav (advisor)
The Bachelor thesis deals with the control of heat sources which are concerned on biomass combustion. The aim of this thesis was to present the properties of biomass as a fuel. It also describes the technology of medium power boilers and their comparison with other power categories. Above all, it evaluates the current control systems of biomass boilers with medium power and offers the list of Czech producers. The thesis also gives the brief information about the situation abroad.

Potential of biomass resources in CZE and costs of its energy utilisation - II
Štěrba, Martin ; Pavlas, Martin (referee) ; Máša, Vítězslav (advisor)
In recent years, we are more and more confronted with the concepts of bio-energy, biomass or biofuels. In conjunction with the increasing pressure on the use of these commodities thein demand is increased. Crops for the purpose of energy production may be an important renewable source of energy and are the primary topic of the work submitted. Introductory chapter provides distribution, characteristics, list of representatives of crops and ways of energy utilisation the crops. Is folloved by an introduction to the legislation dealing with energy crops. The market for biofuels is still in its infancy, and therefore the work submitted presents only general view of the current status of the production and use in the Czech Republic and potential prospects. Interesting is also the position of farmers and the issue of competitiveness. These areas are collectively analyzed in the final chapters.

Biomass in heating systems of cities and villages - II
Tomšů, Ondřej ; Pavlas, Martin (referee) ; Máša, Vítězslav (advisor)
The work deals with district heating systems in towns and villages. It presents the heating supply system, features the history of district heating in the Czech Republic, divided into several characteristic periods and future outlook. The next chapter deals with the division and a description of heat sources. There are statistics shown in the use of district heating systems in the Czech Republic and European countries. A large part of the work is devoted to fuels used in heat sources and their distribution. The main emphasis is put on biomass, there are described all the important parameters, and its species, methods of processing and utilization for getting the heat. The work is concerned with cogeneration technology, which uses the joint production of heat and electricity, there are listed its main advantages and described trigeneration technology. The final part is devoted to the financial aspect of district heating systems. There are listed examples of effective projects, given the example of heat station with a very short period of return of investment and a final assessment of the economic and technological performance of new and existing district heating systems.

Reconstruction of heating system of appartment building - II
Vohralík, Lukáš ; Chlápek, Petr (referee) ; Máša, Vítězslav (advisor)
The aim of my bachelor text was to design a reconstruction of houses' heating. The design is prepared with regard to a house location, heating medium availability and owner's financial possibilities. Thermal insulation plays the key role in the final result i.e. a facade heat-insulation and exchange of windows. It is necessary to use a suitable controling of a designed heating system as the energy prices are increasing. Every time we have to keep in mind minimizing of harmful environment effects that are coming up with a new boiler house's location.

Utilisation of recycling machines in complex approach to waste treatment
Černý, Ondřej ; Máša, Vítězslav (referee) ; Bělohradský, Petr (advisor)
The purpose of the thesis is to describe and evaluate a contemporary state of waste management in the Czech Republic in comparison with European Union. One of its goals is to point out permanently increasing amount of waste, which is produced by people. It also analyzes the principle in the area of planning, future processing and utilization of waste material. Then it deals with the specific cases in the waste management system of entrepreneurial entity that was chosen by us, and with the machines including their technical parameters, which this entity disposes at present period with.

Biomass in heating systems of cities and villages - I
Soudek, Ondřej ; Pavlas, Martin (referee) ; Máša, Vítězslav (advisor)
Point of this bachelor’s thesis is in acquainting with district heating problems. Emphases is posed for a technologic items of this system. Present trend is the cause of dissemination of biomass utilization in district heating over liberal possibility of distribution of heating. So bachelor’s thesis deal with vignette common fossil fuel. A new district heating system realization visualize extensive project and include project of thermal source, junction exchange station and heat distribution.

Potential of biomass resources in CZE and costs of its energy utilisation - I
Votava, Jakub ; Urban, Lukáš (referee) ; Máša, Vítězslav (advisor)
This bachelor thesis ,,Potential of biomass resources in CZE and costs of its energy utilization,, evaluates financial part of energetic use of biomass and summarizes factors affecting the price of biomass on Czech market. The work is focused on wood chips. In the introduction there is an overview of basic division of biomass and utilization as an energy source. Next chapter is about wood chips, their production and properties. Second part of the thesis describes the occurrence of lumber companies in Czech Republic and assessment of wood chips price.
