    Abstract: The condensate of a closed cycle power plant that uses an organic working fluid for lubricating the bearings of the turbine is cooled to a temperature below the condenser temperature by an auxiliary cooler before being supplied to the bearings. This subcooling of the lubricating liquid increases its viscosity to a value which causes the minimum thickness of the lubricating film in the bearings to be increased significantly. By increasing the minimum film thickness, the filtering demands on the lubricating condensate are reduced and the surface finish of the journals and bearings is less critical permitting the journals and bearing to be finished by standard precision grinding techniques. In a specific embodiment of the invention, a cannister housing the turbine/generator is provided with a sump for collecting liquid working fluid which is delivered to the bearings through a cooler. Where the prime mover is coupled to a generator through a gear box, all of which are contained in the sealed cannister, the viscosity of the condensate may be increased to such a level that the cooled working fluid is adequate to lubricate the gear box itself.

    Abstract translation: 使用有机工作流体润滑涡轮机轴承的封闭循环发电厂的冷凝物在供给轴承之前通过辅助冷却器被冷却到低于冷凝器温度的温度。 润滑液的这种过冷将其粘度提高到使得轴承中润滑膜的最小厚度显着增加的值。 通过增加最小膜厚度，减少对润滑冷凝物的过滤要求，并且轴颈和轴承的表面光洁度不太重要，允许通过标准精密磨削技术完成轴颈和轴承。 在本发明的一个具体实施例中，容纳涡轮机/发电机的罐座设置有用于收集通过冷却器输送到轴承的液体工作流体的贮槽。 在原动机通过齿轮箱联接到发电机的情况下，所有这些都包含在密封的罐中，冷凝物的粘度可以增加到使得冷却的工作流体足以润滑齿轮箱本身的水平。

    Abstract: A rotary system including a rotor, a rotating shaft, and a housing surrounding the shaft and the rotor, sealing between a process zone containing the rotor and a lubricant zone being provided by a seal fluid injected into the housing between the two zones at a relatively high pressure, the seal fluid having been separated from the working fluid used in the process zone.

    Abstract: A dual fluid Rankine cycle powerplant utilizes one fluid, such as water, as the working medium and another fluid, such as a glycol, ether, polyglycol ether (both alkyl and aryl) or polyphenyl as the lubricant. The lubricant is fully soluble in the working medium and has a substantially higher boiling point than the working medium. The two fluids are separated from one another prior to entering the engine by heating the mixture of the two liquids to the evaporation temperature of the working medium and then separating the vapor from the liquid lubricant. Thereafter, the vapor can be superheated to increase the thermal efficiency.
