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.

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.
