A new 600-kW Rankine cycle engine with a Sunstrand bottoming cycle that can convert nearly a quarter of the waste heat into electricity is now on the market for about $400,000, has a two-year payback period, and appears to be more practical than most energy-conservation proposals. Three factory-assembled, easily installed units include a heat-recovery unit, power-conversion module, and a control-panel module. The bottoming cycle uses an organic fluid, toluene, instead of steam so that smaller boilers and turbines and a lower temperature can be used. The system can adjust to varying temperatures and heat supplies. Sunstrand has found that, because customers are often unfamiliar with their actual waste-heat conditions, errors could be made in designing a specific application. Five units are undergoing field tests funded by DOE and a sixth by private funding for the purpose of designing hardware for commercialization.
