Physical properties and combustion characteristic of fuels
Nejezchleb, Radek ; Skryja, Pavel (referee) ; Kermes, Vít (advisor)
The subject of this bachelor’s thesis is creating an open calculation tool for determination of elementary properties of gas fuels and calculation of basic combustion characteristics. The theoretical part is focused on chemical equations by combustion, basic equations for calculation of process in gases and calculation of heating value, explosive limits and Wobe index. The most used gas fuels are described furthermore. The next part of bachelor’s thesis is focused on oxidant, especially on the calculation of composition of moist air and mixing of air and oxygen. Equations for the computing of enthalpy of gases and adiabatic heating temperature are noted at the end of the theoretical part.

Power Increasing of Serial Combustion Engines
Novák, Pavel ; Svída, David (referee) ; Dundálek, Radim (advisor)
In this bachelor’s thesis is presented suvey of technical resolution for power increasing of serial combustion engines. The work is oriented especially on technical resolution for spark ignition engine and diesel engine. First two chapters says obout way of combustion process and obout creation the fuel mixture of spark ignition engine and diesel engine. In other chapters is described change length of suck pipeline, mechanical and turbo boosting engine and variable valve timing which is depended on the engine load. At the close there is short muse obout future in tecnical development.

Experimental reactors for combustion of biomass and municipal solid waste
Bialožyt, Michal ; Juřena, Tomáš (referee) ; Recman, Milan (advisor)
The main purpose of this thesis is background research about experimental reactors for combustion process research. Mainly semted on reactors with fixed bed for alternative fuels, such as biomass and municipal solid waste. Mathematical modeling of the combustion process with modern software products and its optimalization is not possible without input data gathering from these facilities. Thesis should serve as a source of information for building a new experimental reactor.

Fireplace inlay
Štelcl, Otakar ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
Bacheor´s work is divided into four main parts. First part deal with division of fireplace inlays according to material, construction of combustion chamber, combustion air, heat transmission and used grate. Second part deal with ČSN EN 13229. Majority part of work deal with problematic of measurement instruments, measurement section of combustion products and also with measurement of effectivity of fireplace inlay. Last part of Bacheor’s work speak about possibilities of optimalization effectivity in whole amount of power of fireplace inlay.

Potential of biomass utilization in the Czech Republic
Klímová, Jana ; Otáhal, Jan (referee) ; Košner, Jan (advisor)
Main task of this bachelor work is to focus on splitting and usage of alternative, renewable energy source – biomass, as a source of thermal and combined electrical energy and to review possibility of increasing of consumption of this source on territory of the Czech Republic. In this work certain kinds of biomass, potential and possibility of it’s usage suggestion for utilization, according to Action plan for biomass and main ways of it’s development will be presented.

Multi-point Injection
Slavík, Tomáš ; Svída, David (referee) ; Dundálek, Radim (advisor)
The main objective of this Bachelor degree thesis is to describe and to bring closer the function of the multiple fuel injection system (nebo the function of fuel injections with multiple sets) in spark-ignition combustion engines, as well as to create a summary of individual components in fuel injection frameworks together with describing their functions and comparing them with other alternatives in fuel systems. In the conclusion, an elaboration on development trends in combustion engines will be provided.

Vliv tepelné elektrárny na životní prostředí
Huvar, Karel
Combustion of fossil fuels in the energy sector is one of the largest sources of air pollution in the Czech Republic. This thesis describes the conversion of heat energy in coal power plant into electricity. It compares the combustion plants of solid fuel. It compares combustion of coal, biomass and solid alternative fuels. It analyzes the resulting pollution from the combustion of solid fuels and its impact on the environment. It also describes the use of cogeneration. There are mentioned the methods of disposal and elimination of harmful substances and waste products of solid fuels combustion and their use. It deals with a preview of the future of classical power engineering in the Czech Republic.
