ORC Geothermal Power Plants and Waste Heat to Power Plants (Organic Ranking Cycle)

Waste Heat to Power

ORC based energy recovery ORC can be used with mrdium or lower temperature heat sources

Medium Temperature: 450 to 1200 F (230-650 C)Typical sources: Gas Turbine exhaust; steam boiler exhaust; reciprocating engine exhaust; heat treating furnace; drying and baking ovens; cement kiln

Low Temperature: Below 450 F (230 C)Typical sources: Process streams; cooling water from furnaces, air compressors, IC engines; steam condensate; exhaust gases exiting primary recovery devices.
