Gas Boiler
Štipský, Pavel ; Křemínský, Pavel (referee) ; Lisý, Martin (advisor)
The aim of this diploma thesis is to design a gas boiler for blast furnace gas combustion. At the beginning is performed stoichiometry of the used fuel to determine the optimal amount of combustion air and the actual amount of flue gas. Subsequently is determined the overall efficiency, together with heat and steam power of the boiler. The main part of the thesis is focused on the design of the combustion chamber and the dimensioning of heat exchange surfaces. At the end of the thesis are performed hydraulic and aerodynamic calculations to determine the pressure loss on the side of the working medium and flue gas. Drawing documentation can be found in attachments.

Calculation of Brown Coal Boiler for SCR Application
Mizerovský, Karel ; Bursa, Robert (referee) ; Skála, Zdeněk (advisor)
This Master´s thesis deals with the verification calculation of boiler which burns brown coal for the application of the selective catalytic reduction method. The thesis is divided into several parts. In the first of all is performed the calculation of the furnace chamber which involves stoichiometrics calculations and enthalpy calculations of air and flue gas. In the second part the heat balance of the boiler, the boiler losses and the thermal efficiency are determined. After all the heating surfaces are calculed for the verify the dimensions. In the conclusion of the thesis we looked for the temperature range which is used for the SCR application. Then the improvements for the appropriate temperature range are designed.

The heating system with accumulation
Bártů, Marek ; Moskalík, Jiří (referee) ; Štelcl, Otakar (advisor)
Bachelor's thesis "The heating system with accumulation" is concerning with an appropriate solution of heating of a house. The thesis is divided into two main parts. The first part is dedicated to theoretical introduction that clarifies the issue of accumulation tank and describes how it works and what kind of processes takes place here. The second, practical part is devoted to calculation of losses and design of heating system in combination with the accumulation medium. As a model example is taken a house in Brno - Židenice.

Modern Application for Household Heating
Šoupal, Filip ; Brázdil, Marian (referee) ; Lisý, Martin (advisor)
This bachelor thesis is focused on the research of basic sources, methods, and possibilities of heating modern family houses. The thesis is divided into three parts, the first one is focused on the advantages and disadvantages of individual heating sources in the use of renewable and non-renewable energy sources. The next section thoroughly describes and compares the methods of heating considering current emission standards. At the end, there is a technical and economic comparison of the variant of the current gas boiler with the variant of the automatic coal boiler and the modern heat pump. The comparison in interpreted on a model house through performed calculations. For better accuracy, the thesis is enhanced with pictures and tables.

Effect of operating parameters of the boiler on presence of fine particles in flue gas
Košťál, Jan ; Poláčik, Ján (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis is devoted to the issues of the formation of fine particles in dependents on the combustion parameters. The first part of thesis is review, which summarized the information about combustion process and about formation of the gaseous products and fine particles inside them which created during combustion process. The main content of thesis is realization of measurements of fine particles from combustion, in several types of the tested combustion devices. Next part is a description of used measurement devices, which used for measurement. Last chapters are focused on evaluation of results from the measurements, comparison of the measurements between themselves and the finding the existence of the dependence of the formation of fine particles on operational parameters of boiler. And all results are evaluated in the conclusion.

Alternative Energy Resources for Family House
Buráň, Petr ; Štelcl, Otakar (referee) ; Špiláček, Michal (advisor)
In this bachelor thesis we will focus on alternative energy resources for family house. The thesis consists of two main chapters. The first chapter is focused on research, in which we will sequentially introduce different resource of energy and describe their principle of operation. In the second chapter we will create proposal designs for different energy resources for family house and their price comparisons.

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.

Steam boiler for natural gas
Křivánek, Robin ; Kohout, Přemysl (referee) ; Skála, Zdeněk (advisor)
This diploma thesis describes the design of steam boiler for combustion natural gas, which has a steam power 80t/hour. In the first phase is performed calculation of stoichiometric amount of combustion air and flue gas. After that follows constructional proposal of the combustion chamber. Furthermore continue by calculation heating surfaces of the boiler. In conclusion, the thesis is focused on designing the injections. To check the accuracy of the results is recalculated heat balance the whole boiler.
