Conversion of Low Quality Waste Heat to Electric Power with Small-Scale Organic Rankine Cycle (ORC) Engine/Generator Technology

Abstract : An Organic Rankine Cycle generator (ORC ) converts low-grade waste heat (250 C) into electric power using organic working fluids with lower boiling points than the common steam-based Rankine cycle. The demonstration objectives were to verify the performance, economics and applicability of the ElectraTherm ORC in both controlled load and real world conditions at a DoD site.
