Résumé

A steam expander has been studied for its usability as a power conversion device in a Rankine cycle, which can be used for on-site power generation or waste heat recovery. Design of a swash plate type expander has been practiced and its performance has been estimated. With the steam pressure and temperature of 3.5 MPa and 300°C at the expander inlet, respectively, it was calculated that the expander produced the shaft poweroutput of about 2.88 kW from the steam heat source of 25 kW. The expander output increased lonearly with increasing the steam heat amount. For a given steam heat amount, the expander power increased with increasing the inlet steam temperature and it was not affected much by the inlet steam pressure. The expander efficiency was more or less constant at around 75%, regardless of the steam condition at the expander inlet.
