The Development of Portable, Reciprocating Engine, Rankine Cycle Generating Sets

Three steam engine driven prototype portable generator sets ranging in power from 100 W (e) to 1500 W (e) are described. To a large extent, these sets have demonstrated the potential capability of the Rankine cycle for low noise, low exhaust emissions, high reliability, acceptable efficiency, and multi-fuel operation. Design criteria used in the development of these units and their general applicability to reciprocating Rankine cycle systems are discussed. Recent developments make this power cycle attractive for commercial applications in present sizes as well as in scaled-up versions.
