A waste heat recovery system is effective technology for ship energy saving. However, it is not practical used for a small-size ship, because it has too large scale and low efficient performance for the ship. We study a marine waste heat recovery system used a reciprocating steam expander of Rankine Cycle. An axial flow turbine expander is widely used for a general marine waste heat recovery system. However, the efficiency of the axial flow turbine expander is not so high, when steam flow rate is low or has different design condition. A volumetric expander like the reciprocating steam expander has a possibility to get a high efficiency in every condition. Firstly, we design a small-size expander for experiments, which uses compressed air for power source. And we make a simulation model of expander. As a result, we estimate fundamental performance of the expander.
