ステムの簡素化を狙って、作動媒体と完全に溶解できる
潤滑油を用いている。In the conventional binary power generation system using the screw turbine, the lubricating oil used for lubricating the screw turbine and heating the working medium is completely dissolved with the working medium in order to simplify the system. Uses a lubricating oil that can.

である。Therefore, when the temperature of the lubricating oil decreases, such as when the system is stopped, the working medium dissolves in the lubricating oil at an arbitrary ratio (see FIG. 2). In Fig. 2, the vertical axis indicates pressure (kg

せ、安定運転の妨げとなる。Further, in the binary power generation system using the screw turbine, the medium circulation operation is performed before starting the screw turbine in order to ensure stable operation, and the equipment is warmed up. Warming-up is performed by circulating the working medium vapor from the evaporator by bypassing the screw turbine and sending it to the condenser. At this time, the medium liquid is likely to collect in the pipe in front of the emergency shutoff valve. When the emergency shutoff valve is opened and the operation is started in the state where the liquid is accumulated in the pipe, the medium liquid is mixed with the lubricating oil, and the viscosity of the lubricating oil is reduced, which hinders stable operation.
