  • the rankine cycle system includes an evaporator or a boiler for evaporation of a motive fluid, a turbine that receives the vapor from the evaporator to drive a generator, a condenser for condensing the vapor, and a pump or other means for recycling the condensed fluid to the evaporator.
  • the motive fluid in rankine cycle systems is often water, and the turbine is thus driven by steam.
  • An organic rankine cycle (ORC) system operates similarly to a traditional rankine cycle, except that an ORC system uses an organic fluid, instead of water, as the motive fluid.
  • Oil may be used for lubrication in the ORC system, particularly inside the turbine.

  • An organic rankine cycle (ORC) system may be used to generate electrical power.
  • Oil is used within the ORC system to provide lubrication for various pieces of equipment, particularly inside a turbine of the ORC system.
  • the oil may travel to other areas of the turbine where the oil is not needed, and in some cases, the oil may be destructive to some of the equipment.
  • the system is starting up, if there is oil in certain areas of the turbine, such as the impeller, the oil may result in a system failure.
  • This disclosure focuses on a method and system for effectively removing the oil from the turbine during a startup of the ORC system.
  • 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.
  • Refrigerant 22 exiting evaporator 16 is a vaporized refrigerant (22b), at which point it passes through turbine inlet valve 26 and into turbine 18.
  • Vaporized refrigerant 22b is used to drive turbine 18, which in turn powers generator 28 such that generator 28 produces electrical power.
  • Vaporized refrigerant 22b exiting turbine 18 is returned to condenser 12, where it is condensed back to liquid refrigerant 22a.
  • Heat sink 30 is used to provide cooling water to condenser 12.
  • Eductor system 20 is connected to turbine 18 and is configured to remove oil from those areas of turbine 18 where it may commonly collect. As explained in more detail below in reference to FIG. 2, eductor line 32 receives a portion of vapoiized refrigerant 22b flowing from evaporator 16 and delivers refrigerant 22b to eductor system 20.
  • ORC system 10 also includes bypass valve 36 and bypass line 38, which may be used to prevent refrigerant 22b from passing through turbine 18 during a startup.
  • turbine 18 temporarily runs in a bypass mode, at which time it does not receive any refrigerant, in order to reach the predetermined operating conditions (i.e. temperature and pressure) for turbine 18.
  • refrigerant 22b flows through bypass line 38 and is directed through bypass orifice 39 to increase a temperature of refrigerant 22b, and imitate operating conditions inside turbine 18.
  • bypass valve 36 is closed when turbine inlet valve 26 is open, and vice versa.
  • FIG. 2 is a schematic of a portion of ORC system 10 from FIG. 1, including turbine 18, eductor system 20, eductor line 32, turbine inlet valve 26, generator 28, bypass valve 36, and bypass line 38.
  • Turbine 18 includes impeller 40, discharge housing 42, and high pressure volute 44.
  • Volute 44 is designated as "high pressure volute” since the volute is at high pressure when turbine 18 is operating. However, volute 44 is at low pressure when system 10 and turbine 18 are in the bypass mode during startup.
  • vaporized refrigerant 22b passes through inlet valve 26 into high pressure volute 44, and then through nozzles 46, which impart motive force to impeller 40 to drive shaft 48 inside gear box 50.
  • Gears 52 connect drive shaft 48 to generator 28, which uses the shaft energy to generate electrical power.
  • Gear box 50 also includes bearings 54, oil sump 56, and oil pump 58.
  • Eductor line 32 is located upstream of turbine inlet valve 26, and is configured to receive a portion of vaporized refrigerant 22b exiting evaporator 16 (and flowing to turbine 18). Line 32 then delivers refrigerant 22b to eductor system 20, which is configured to remove liquid (primarily oil) from turbine 18.
  • eductor line 32 is located downstream of bypass line 36; in alternative embodiments, eductor line 32 may be located upstream of bypass line 36.
  • eductor line 32 By placing eductor line 32 upstream of turbine inlet valve 26, eductor line 32 is able to continuously supply refrigerant 22 to eductor system 20 whenever refrigerant 22 is circulating through system 10, regardless of the mode of turbine 18. Even if turbine 18 is in a bypass mode during startup and refrigerant 22 from evaporator 16 is being diverted through bypass line 36, refrigerant 22 may still flow to eductor system 20.
  • the eductor line may commonly be connected to the turbine such that the refrigerant source for the eductor system is delivered from the turbine.
  • the eductor line may be connected to the high pressure volute such that the eductor system uses refrigerant that was flowing through the high pressure volute of the turbine.
  • the eductor system is only operable when refrigerant from the evaporator is flowing through the turbine.
  • the vaporized refrigerant from the evaporator is prevented from flowing through the turbine.
  • the refrigerant instead flows through the bypass line, and then to the condenser.
  • the startup mode may be an important time for removing oil from those areas of the turbine surrounding the impeller (i.e. the high pressure volute and discharge housing). Some of the equipment inside the turbine may be damaged if the turbine starts up with oil in these areas. Moreover, during operation and particularly during shut down of the ORC system, the oil inside the turbine commonly migrates to the discharge housing and the high pressure volute.
  • 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.
  • eductor line 32 may include a control valve. As shown in FIG. 2, eductor line 32 may include filter 60, which is configured to remove particulates from refrigerant 22.
  • eductor system 20 includes first eductor 62 and second eductor 64, which operate as venturi devices, and each includes a primary flow inlet and a secondary flow inlet. In each eductor, high pressure refrigerant from evaporator 16 flows through the primary flow inlet, creating enough suction force to draw liquid out of turbine 18.
  • Eductor system 20 also includes first line 66 and second line 68, both of which are connected to eductor line 32.
  • First line 66 is configured to deliver refrigerant 22 to primary flow inlet 70 of first eductor 62.
  • Secondary flow inlet 72 of first eductor 62 is connected to line 74 and delivers oil 76, which is removed from discharge housing 42 of turbine 18, through first eductor 62.
  • Second line 68 is configured to deliver refrigerant 22 to primary flow inlet 78 of second eductor 64.
  • Line 80 is connected to secondary flow inlet 82 of second eductor 64 and delivers liquid removed from high pressure volute 44 of turbine 18.
  • Liquid extracted from high pressure volute 44 is mostly oil; however, the liquid may include some of the refrigerant flowing inside turbine 18. After flowing through eductors 62 and 64, the refrigerant and the oil collectively travel to oil sump 56 through line 84. The refrigerant, which is vapor, may be recycled back to discharge housing 42 from sump 56 via line 86.
  • eductor system 20 includes two eductors, it is recognized that eductor system 20 may operate with only first eductor 62. Because eductor line 32 is located upstream of turbine inlet valve 26, eductor line 32 may deliver refrigerant to first eductor 62 at all times.
  • first eductor 62 is effective at removing oil from turbine 18, particularly during a startup of turbine 18.
  • system 10 By removing oil from discharge housing 42 prior to starting up turbine 18, system 10 exhibits a decrease in a number of failed startups, as compared to an ORC system in which the eductor system is not operable during startup because it is dependent on refrigerant from the turbine.
  • second eductor 64 is not required, it is recognized that using second eductor 64, in combination with first eductor 62 and eductor line 32, further increases the effectiveness of system 10 for removing oil from turbine 18.
  • oil may collect in both discharge housing 42 and high pressure volute 44.
  • Second eductor 64 is able to remove oil from high pressure volute 44, where it commonly collects once the oil is separated from the vaporized refrigerant inside volute 44.
  • Using a two- eductor system improves overall recovery of the oil because the oil may be removed from both areas around impeller 40 where it can accumulate.
