Piston steam engine
Hrbáček, Jaroslav ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
Object of this document is possibility of using piston steam engine (later only SE) in steam boiler plant, heating plant and steam reduction station. There is implemented a thermodynamic suggestion of SE for defined parameters of mechanical power 20 kW, frequency 1500 cpm, input steam pressure 1,5 MPa and warmth inside steam condenser 105 °C. There are implemented the main construction segments of SE with a view to steam distribution system. For determine a shape of work diagram SE (p-V diagram), there was created a supportive programme in Excel. The programme serves as the basis of determination of motor stroke volume and basis of determination of main dimensions.

Solutions for using micro cogeneration in places where are not primarily available gas or liquid fuels
Kubínek, Martin ; Štelcl, Otakar (referee) ; Vojáčková, Jitka (advisor)
This bachelor´s thesis deals with the usage of micro cogeneration units in the places where gas and liquid fuels are not primarily available. In the research part, the available technologies and the current condition of the market of micro cogeneration units, which use solid fuels, especially biomass, are described. In the technical-economical part, there is a design of the specific unit whose thermal output corresponds to the thermal rated loss of the chosen building. The payback period of the unit with a gasifier and with a combustion engine is estimated in the cases when the chosen building is currently heated by: lignite, wooden chips, electricity and the combination of natural gas and coke.

Technological solution of biomass power station with steam engine.
Pleban, Jakub ; Lisý, Martin (referee) ; Škorpík, Jiří (advisor)
This work describes function and main parts of a heat plant burning biomass. The work is thematically divided into five parts. In the first part there are presented possible sorts of energy which are suitable for generating both electric and heat energy. The second part of the work describes basic principles of the plant functioning. The third part which relates to the second one is focused on the given technologic scheme of the plant. The fourth part closely analyses a function of a steam piston engine and its main components. In the last part there is assessed the actual situation in the field of heating plants in the Czech republic.

Piston steam engine
Potměšil, Tomáš ; Fiedler, Jan (referee) ; Novotný, Zdeněk (advisor)
The thesis is concerned with posibility of using piston steam engine in minor local steam boiler plants and steam reduction stations. Shortly describes a history of steam engines, analyses and explains positives and negatives of different control gear conceptions and then a 3D model of selected conception is formed. Mainly there is implemented a thermodynamic proposal of steam engine for defined parameters of mechanical power 25 kW, frequency 1500 rpm, input steam pressure 1,5 MPa. Main dimensions of engine parts are determined. Lastly the work compares differences between piston steam engine and single-stage steam turbine and in principle reasons advantages of steam engine in reduction station.

Animované modely tepelných motorů
Honzl, Michal
The present diploma thesis "Animated models of heat engines" describes the design of an interactive application. The theoretical part deals with the classification of heat engines and their rotations. The result of the present diploma thesis is the new application "Animation of heat engines" designed in Flash programme. This application is focused on the basic function principle of four demonstrated engines. The present work also deals with assessing and comparison of real engines, their cuts, real models and animated engines.
