Fine particles emitted from a heat source into the indoor environment
Hájek, Jiří ; Köbölová, Klaudia (referee) ; Pospíšil, Jiří (advisor)
This bachelor's thesis deals with fine particles emitted to indoor space during combustion in fireplace stowes. The beginning of work is focused on the description of biomass and its combustion. In the following part the pollutants, which are produced by combustion of bio-mass are mentioned, and last but not least is attention focused on current air quality in Czech Republic methods of measure of solid pollutants and measuring equipment. Calculation of concentration is closely described in the experimental part, and then the data, which was measured on different modes of operations of fireplace stowes, is presented.

40/5000 Fine particles produced by the stove
Škvařil, Ondřej ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
This master thesis deals with problematics of fine particles produced during combustion in fireplace stoves. The theoretical part is focused on the analysis of the atmosphere, health consequences, solid pollutants, the formation of particles (origin), particle separation and how they are regulated by laws. Theoretical section of the thesis addresses analysis of biomass and its combustion. In the applied section are listed given methods of the particles measuring according to regulations, common errors during measurement and methods of identification of measured fine particles. Then follow specific measurements of the formed very fine particles produced by the SMPS method. Subsequently, the results of the measurement are evaluated and summarized in the conclusion.

Design of Fireplace Stoves
Crhová, Veronika ; Sládek, Josef (referee) ; Sovják, Richard (advisor)
This Bachelor’s thesis deals with designing a hot air stove for solid fuels. The stove is designed to accumulate a huge amount of heat and to heat the space. The main idea is to work with unusual material. The concept is build on simple design and function. The thesis is composed of current market trends, design process and technical parameters.

Proposal for a stove fire
Štelcl, Otakar ; Skála, Zdeněk (referee) ; Baláš, Marek (advisor)
Abstract The diploma thesis is divided into five main parts. First part deals with wood as a firing in term of its composition, emissions of carbon dioxide and its properties. The second part describes the calculation of a stove fire, especially stoichiometry of firing, temperature of uncooled flame and area of combustion chamber. The third part focuses on the proposal for a stove fire in connection with comparative criteria of the fireplace, shape of the combustion chamber and the tertiary air jet. The fifth part describes a manufacturing of the stove fire in the work-room at VUT Brno. The major part of the diploma work pays attention to the measuring of stove fire parameters for the effectivity calculation, measuring section of combustion gas and measurement evaluation with stove fire constructional modifications

Biomass heating options
Synek, Michal ; Baláš, Marek (referee) ; Štelcl, Otakar (advisor)
This bachelor thesis is divided into five main parts. The first part divides stoves according to the type of grate, material, trasmission of heat and combustion of gasses. The second part deals with the ČSN EN 13 240 norm. The following parts discuss measurement points and the devices used for measuring and test fuel. The last part deals with the collected data, the results drawn from these data and the efficiency calculation.

Design of fireplace type stoves
Foltýn, Jakub ; Rubínová, Dana (referee) ; Zvonek, Miroslav (advisor)
This bachelor`s thesis concerns with a design project of contemporary woodburning stove intended to burn solid fuels especially wood based fuels. It aims to advantages of home heating and tries to analyse dilemma of heating devices from historical, technical and design point of view. The outcome of this thesis is simple, modern and shape-interesting project of the stove which in the same time leaves traditional character to the stove. The study contains text part, 3D model, summary poster and real prototype of the stove.

Analysis of the influence of energy prices on stove saleability as an alternative source of heating
Bohumínský, Roman ; Chytilová, Helena (advisor) ; Babin, Jan (referee)
Since it is possible to observe quite stable rise in prices of energies, the question whether households are reacting by substituting the sources of energies arises. In this aspect, households can reduce their costs mainly on heating. That is why this thesis analyses the link between prices of coal, electricity, natural gas, wood (in exchange and supplier forms -- these being the independent variables) and sales of stoves which are used as dependent variable and are viewed as an alternative source of heating leading to possible cost reduction. We also calculate with the average wage, unemployment and temperature. The data source consists of time series following years 2011 and 2012 which were collected on daily basis in Czech Republic. To quantify this link, we introduce 8 different OLS estimates differing in price and properties of the stoves. We managed to verify the link between energy prices, unemployment, average wage and sales of stoves. We have found out that there is negative relation between wood and even coal prices, which are accounted as complements to stoves. Positive significant relation is present for prices of natural gas and also for the average wage. When we divided the dataset according to average price of stoves, we acquired different magnitudes of response for data obtained from stock exchange and suppliers of energies. By this division, we detected positive effect of unemployment (unfortunately slightly nonsignificant) with cheaper stoves and negative effect with more expensive ones.
