Comparison of methods of determination of LHV and HHV
Jahn, Jiří ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This bachelor thesis is focused on the comparison of the accuracy of the determine of the higher heating value and lower heating value using the equations. The calculation is based on the contents of samples in the fuel, ie from the data obtained by ultimate analysis. Higher heating value and lower heating value of each fuel type was obtained by calorimeter measurement and considered to be the exact value of the fuel. The output of the work is the evaluation of suitability and accuracy of the examined equations and introduction equations appropriate for biomass.

Production of Unmeasured Emissions by Combustion in House Boilers
Chlubna, Martin ; Lisá, Hana (referee) ; Lisý, Martin (advisor)
This bachelor thesis deals with the production of non-monitored pollutants during combustion in domestic boilers. The theoretical part is made up of a research study dealing with pollutants and their legislation. In the experimental part combustion tests for coal and wood of different moisture are made. In conclusion, the measurement results are evaluated on the basis of chemical analysis.

Agropellets Properties
Němeček, David ; Špiláček, Michal (referee) ; Lisý, Martin (advisor)
This thesis solves problems of combustion of agropellets and the advantages and disadvantages, which are connected with their application in combustion devices. In this thesis at first there is divided biomass, where it primarily concentrates on the plant biomass and it constitutes some used types, which are used to a fuel production. In the next part it solves problems of production of pellets, the advantages and disadvantages of this production and the advices for superior pellets. In the final theoretical part it solves combustion of this fuel. It is about properties of pellets, problems of combustion and this work also deals with emissions of combustion agropellets. In the last part the thesis engages in experimental detection of agropellets properties and plant biomass as such and subsequent comparison to wood biomass and tabular values.

Topical and Advanced Possibilities of Heating by Thermal Pumps
Božek, Michal ; Brázdil, Marian (referee) ; Lisý, Martin (advisor)
The bachelor's thesis is focused on search of one of the many methods of home heating systems, specifically on heat pumps. The first part describes the structure of heat pumps, the principle of how they work, main types, their two most important parameters and comparison of them to other systems of heating. The second part contains comparison of individual heating systems from economical point of views on a selected model house.

Agropellets for House Boilers
Čaňo, Lubomír ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
This bachelor thesis deals with the characteristics of the agropellets and with their combustion in the house combustion units. In the introduction of the first part is described what the agropellets are and how they are produced. It is followed by a characteristics of the agropellets as a fuel and by their comparison to the other solid fuels. The end of the first part is dedicated to a combustion itself and the creation of emissions during it’s combustion. The second part of the bachelor thesis is focused on a practical verification of the characteristics of the selected agropellets as a fuel. It also includes the experimentally measured values of emissions during their combustion.

Increasing of electricity production in BGS using ORC cycle
Beck, Michal ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
Objective of this Master’s thesis is to make search about generation and use biogas, with focus on cogeneration and to make search about possibilities of increasing the share of production of electricity by cogeneration from biogas. This final work has also the task to summarize possibilities of increasing the share with ORC cycle and to evaluate pros and cons of this use. Main part of this work is dealing with own design of increasing production of electricity with cogeneration from biogas in biogas station with ORC cycle and comparing this modification with steam engine.

Impact of Biomass Storing on Heating Value
Černý, Michal ; Špiláček, Michal (referee) ; Lisý, Martin (advisor)
The main aim of my bachelor´s work is the experimental verification of the landfill impact on the parameters biomass. The first part deals with definition, the formation of a basic biomass division. In the next section we find the issues concerning the burning, fuel composition and emissions during combustion. The last part deals with the influence of climatic conditions on the biomass degradation. In the experimental part were measured calorific calorimeter. The result was that, after a measured period of five months to avoid significant degradation of the fuel.

Re-design of biomass boiler for very wet fuel
Zbořil, Martin ; Skála, Zdeněk (referee) ; Lisý, Martin (advisor)
The aim of this thesis is to calculate the stoichiometric balance of boilers and boiler fuel for normal monture to 60%. Determine the monture, content depending on the conditions of the fuel in the combustion chamber and conditions of combustion. Experimental analysis of the current state of the boiler ZKG measurements using this device and propose modifications and solutions.

Modular Horizontal Heat Recovery Steam Generator
Primes, Alois ; Nantl, Radomír (referee) ; Lisý, Martin (advisor)
This thesis deals with the design of a Heat Recovery Steam Generator (HRSG). Theintroductory part is devoted to a brief description of the boiler, the specified parametersand the compilation of the temperature profile. The main computational part of thiswork is divided into 6 parts. The first contains preparatory calculations, including thecalculation of boiler eiciency. In the second part, a flue gas duct is designed. This isfollowed by a thermal calculation of the boiler for all heat exchange surfaces. The last 3parts deal with the design of the drum, piping and the loss of boiler draft calculation.

Reducing the energy intensity of production area
Tannert, Jiří ; Lisý, Martin (referee) ; Pospíšil, Jiří (advisor)
The diploma thesis deals with possibilities and subsequent proposal of individual measures to achieve the reduction of energy intensity in the company fischer Vyškov, s.r.o. At the beginning of the thesis is the analysis of the current state of the areas on which the work is further focused. These include the production of compressed air, cooling technology and lighting. The main cost-saving measures for the production of compressed air is a proposal to purchase a new compressor. For cooling, there are free cooling options, including the design of a dry cooler and its inclusion in the cooling circuit. The last part is the design of a new lighting system using LED lamps.
