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.
