Waste heat can be utilized by an organic Rankine-cycle system to produce useful electrical or shaft power without any fuel expense. Such a system starts with a heat recovery boiler, which provides saturated or superheated vapor to an expander by transferring heat from the waste-heat fluid to the Rankine-cycle working fluid. Power is extracted in the expander, and the fluid passes on to a condenser, which provides liquid to a feed pump. The feed pump raises the pressure and resupplies fluid to a boiler, thereby completing the cycle. The working-fluid condenser heat is rejected to a cooling fluid in the condenser. Depending on the particular application and working fluid selected, it may be economical to add a regenerator to improve cycle efficiency.
