Definitions
- ORC system 10 which includes condenser 12, pump 14, evaporator 16, turbine 18, and eductor system 20 connected to turbine 18.
- Refrigerant 22 circulates through system 10 and is used to generate electrical power.
- Liquid refrigerant 22a from condenser 12 passes through pump 14, resulting in an increase in pressure.
- High pressure liquid refrigerant 22a enters evaporator 16, which utilizes heat source 24 to vaporize refrigerant 22.
- Heat source 24 may include, but is not limited to, any type of waste heat, including fuel cells, microturbines, and reciprocating engines, and other types of heat sources such as solar, geothermal or waste gas.
- eductor line 32 of system 10 is located upstream of turbine inlet valve 26 and receives refrigerant 22b directly from evaporator 16, eductor system 20 is able to remove oil from turbine 18 during all modes of running system 10.
- Eductor line 32 receives a small portion of refrigerant 22 from evaporator 16 and thus has a minimal impact on operation and efficiency of turbine 18. For example, in one embodiment, less than one weight percent of refrigerant 22 from evaporator 16 flows to line 32; and in a preferred embodiment, approximately 0.2 weight percent flows to line 32.
- eductor line 32 does not include a valve since line 32 is configured to receive refrigerant 22 whenever refrigerant 22 is flowing through ORC system 10.
