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： The present invention provides wind guiding vane apparatus for mitigating a detrimental influence of cross winds flowing in the vicinity of an air-cooled condenser (ACC) and through one or more fans, positioned in lateral direction of the ACC, to which ambient air is directed and discharged to the atmosphere after cooling condenser tubes of the ACC, comprising one or more stationary wind guiding vanes positioned along at least a portion of an air flow streamline and below a plurality of condenser tubes of the ACC, wherein said one or more wind guiding vanes are configured to redirect air flow during windy conditions towards a portion of said plurality of condenser tubes and at least one of the fans at such an angle that significantly deviates from perpendicular, fairly horizontal inflow. The one or more wind guiding vanes are also suitable to maintain a nominal flow rate of air during quiescent wind conditions.

摘要： A heat exchanger system for cooling liquid having a plurality of finned tube arrays and a plurality of fans for inducing air through the finned tube array comprising: at least one wind deflector installed along the long side of the finned tube arrays on at least one side of the arrays. The present invention for includes a method for minimizing the undesired effect of wind on the operation of a heat exchanger system for cooling liquid having a plurality of finned tube arrays and a plurality of fans for inducing air through the finned tube array, the method comprising the steps of: setting the angle of deflection of the wind deflectors other than the angle of deflection of the uppermost position of the wind deflectors; collecting readings of outlet temperature sensor of the heat exchanger, ambient temperature, wind sensor and inlet air pressure sensor of the heat exchanger; recording readings of outlet temperature sensor of the heat exchanger, ambient temperature, wind sensor and inlet air pressure sensor of the heat exchanger; comparing readings of outlet temperature sensor of the heat exchanger, ambient temperature, wind sensor and inlet air pressure sensor of the heat exchanger to previous readings; and carrying out a correction command if the readings have changed.

摘要： A heat exchanger system for cooling liquid includes a generally rectangular arrangement of a plurality of horizontally spaced finned tube arrays arranged above the ground, the arrangement having longer sides extending in a length direction and shorter sides extending in a width direction. A plurality of fans are provided above the finned tube arrays for inducing air through the finned tube arrays, wherein at least two of said fans are mutually spaced in the width direction. At least one wind deflector is provided adjacent one of the longer sides, wherein the at least one wind deflector is installed on the ground separately from any of the plurality of finned tube arrays.

摘要： A method for stimulating a sub-commercial geothermal well includes steps of drilling a stimulating well; isolating a corresponding zone in the stimulating well using vertically spaced swell packers that are swellable when contacted by subterraneously heated geothermal brine present in the stimulating well and are resistant to the high temperature of the brine; injecting stimulating fluid into the stimulating well such that it will flow only through a zone of the well that is not isolated; and allowing the stimulating fluid to exit the well from a non-isolated zone located at a desired depth into a surrounding geological formation. The fracture or system of fractures within the formation is thereby hydraulically reopened.
