Conception and First Functional Tests of a Novel Piston-Type Steam Expansion Engine for the Use in Stationary WHR Systems

For the recovery of unused process heat of various origins, the use of Rankine-Cycles represents an effective and well-proven strategy. As most commercially available systems are designed for comparably high power, or, if scaled down, are suffering from low efficiency or high costs, the present research project aims at designing a novel steam expansion engine for medium power (for waste heat power around 300 kW).
