摘要： A method for producing power from a heat source comprises the steps of: heating an intermediate fluid with heat from the heat source and producing a vaporized intermediate fluid in an intermediate fluid heater/vaporizer. Heat from the vaporized intermediate fluid vaporizes an organic liquid working fluid present in an organic working fluid vaporizer to form a vaporized organic working fluid and intermediate fluid condensate. The vaporized organic working fluid is expanded in an organic vapor turbine for generating power and producing expanded vaporized organic working fluid; the expanded organic vaporized working fluid being condensed to produce an organic fluid condensate with the organic fluid condensate being supplied to the organic fluid vaporizer. According to the present invention, prior to supplying the vaporized intermediate fluid to the organic fluid vaporizer the vaporized intermediate fluid is expanded in an intermediate fluid vapor turbine and power is produced.

摘要： An energy storage system has a pressure vessel that is exposed to ambient temperatures and that contains a working fluid which is condensable at ambient temperatures (CWF); a liquid reservoir in communication with one of the vessels and containing a liquid that is unvaporizable in the reservoir and in the vessel; and apparatus for delivering the liquid from the reservoir to the vessel. The CWF is compressible within the vessel upon direct contact with the liquid and is storable in a liquid state after being compressed to its saturation pressure. In a method, at least some of the liquid located in the vessel is propelled by the CWF towards a turbine to produce power. In one embodiment, a module has a first vessel having at least four ports, a second vessel at ambient temperatures, and a flow control component operatively connected to a corresponding conduit for selectively controlling fluid flow.

摘要： Turbine apparatus includes turbine wheels by which introduced motive fluid is expanded; a horizontally disposed turbine shaft which is rotatably supported by inlet-side and outlet-side bearings, such that the turbine wheels are fixedly connected to the turbine shaft between the inlet-side and outlet-side bearings; a turbine housing by which the turbine wheels and the outlet-side bearing are encased; and a bearing cartridge in which the inlet-side bearing is housed that is mounted externally to the turbine housing. The bearing cartridge is separable from the turbine housing to facilitate a maintenance operation when the inlet-side bearing is disengaged from the turbine shaft. In a method for accessing a malfunctioning inlet-side component contactable with the turbine shaft in order to perform a maintenance operation, the bearing cartridge is dismounted from a surface of the turbine housing and the bearing cartridge is axially displaced in a direction away from the turbine housing.

摘要： A power system for delivering a custom level of electrical power to an industrial or commercial facility includes a local generator connected to a turbine operating in accordance with an organic Rankine or steam Rankine cycle. The local generator has a capacity at least greater than a maximum anticipated power level needed for the electrical needs of a local industrial or commercial facility. One or more control devices are operatively connected to the local generator for regulating active and reactive power generated by the generator. A controller directs the one or more control devices to regulate the generator such that the active power and reactive power generated by the generator are sufficient to satisfy active and reactive load conditions of local industrial or commercial facilities. Also, a flow control component is operatively connected to the main conduit for automatically limiting the flow of the motive fluid to the turbine module during base load conditions and for automatically increasing the flow of the motive fluid to the turbine module during variable load conditions.

摘要： For minimizing the effect of wind on a heat exchanger system having a plurality of finned tube arrays and a plurality of fans, a method includes providing a wind louver below one of the fans. The wind louver is arranged to divert wind flowing in an approximately horizontal direction below the one of the plurality of fans to instead flow in a direction that is more vertically upward as compared to the approximately horizontal direction. Readings of a heat exchanger outlet temperature, ambient temperature, wind, and inlet air pressure are collected and recorded, and compared to previous readings. The louver height is changed if the readings have changed.

摘要： A waste heat recovery system includes a high pressure turbine and a low pressure turbine, in which the high pressure turbine receives high pressure working fluid vapor, the low pressure turbine receives low pressure working fluid vapor and the high pressure turbine also supplies low pressure working fluid vapor to the low pressure turbine. A recuperator receives working fluid vapor from the low pressure turbine. The recuperator produces heated condensate, at least a portion of which is provided to a high pressure vaporizer. The high pressure vaporizer is configured to receive from a high temperature heat source and produces high pressure working vapor used to power the high pressure turbine. The remaining condensed fluid is provided to a low pressure vaporizer which is configured to receive heat from a low-temperature heat source, thereby producing low pressure working fluid vapor used to power the low pressure turbine.
