Abstract: This paper presents an experimental study conducted on an oil-free steam piston expander for micro-combined heat and power systems. This expander can produce electrical power (between 740 and 2400W) with a significant range of supply temperature (between 260 and 340°C) and pressure (between 20 and 34bar). The expander electrical power output exhibits a fast dynamic response to a change of working or supply fluid conditions. The reached expander overall isentropic efficiency (including electrical generator efficiency) was between 19% and 40%.
