摘要： Systems and methods are provided for the recovery of mechanical power from heat energy sources via multiple heat exchangers and expanders receiving at least a portion of heat energy from a source. The distribution of heat energy from the source may be portioned, distributed, and communicated to the input of each of the heat exchangers so as to permit utilization of up to all available heat energy. In some embodiments, the system receives heat energy from more than one source at one or more temperatures. Mechanical energy from expansion of working fluid in the expanders may be communicated to other devices to perform useful work or operatively coupled to one or more generators to convert the mechanical energy into electrical energy.

摘要： A new power generation thermodynamic cycle is described that eliminates need for bulk liquid condensation and vaporization steps required in conventional ORC power systems. An exemplary harmonic adsorption recuperative power cycle system offers more efficient power generation as compared with conventional ORC systems. A multibed adsorption system is used to provide thermal compression for the cycle. An adsorption compressor contains a sorbent with strong adsorption affinity for the working fluid in the pores while well outside the P-T conditions needed to condense the liquid phase, allowing the adsorption compressor to reduce operating pressure exiting the expander.

摘要： Systems and methods are provided for the recovery mechanical power from heat energy sources using a common working fluid comprising, in some embodiments, an organic refrigerant flowing through multiple heat exchangers and expanders. The distribution of heat energy from the source may be portioned, distributed, and communicated to each of the heat exchangers so as to permit utilization of up to all available heat energy. In some embodiments, the system utilizes up to and including all of the available heat energy from the source. The expanders may be operatively coupled to one or more generators that convert the mechanical energy of the expansion process into electrical energy, or the mechanical energy may be communicated to other devices to perform work.

摘要： Some embodiments of the present disclosure include a method and method for recovery of solution mined minerals. The method may include creating superheated steam using a steam boiler; passing the superheated steam through a turbine/generator to generate electricity; reheating the steam exiting the turbine/generator to saturation with a steam reheater; using the saturated steam with an absorption chiller to create chilled water; and recovering minerals using the chilled water in a cooling crystallizer system. In embodiments, the method and system may be used to recover minerals, such as potash (KCl), washing soda (Na2CO3.10H2O); nahcolite (NaHCO3); and glauber salt (NaSO4.10H2O). The method may utilize the trigeneration of steam, electrical, and chilled water utilities, which may be used for a recovery process.

摘要： Three-way valve with a valve housing and a closing body arranged in a longitudinally movable manner in the valve housing. An inlet channel, a first outlet channel and a second outlet channel are formed in the valve housing. The closing body interacts by longitudinal movement with a first valve seat formed in the valve housing and thereby opens and closes a first hydraulic connection between the inlet channel and the first outlet channel. Furthermore, the closing body interacts by longitudinal movement with a second valve seat formed in the valve housing and thereby opens and closes a second hydraulic connection between the inlet channel and the second outlet channel. A throttle is formed in the second hydraulic connection.

摘要： A steam turbine of an opposed-current single-casing type has a high pressure turbine part and an intermediate-pressure turbine part housed in a single casing. A dummy ring partitions the high-pressure turbine part and the intermediate-pressure part, and a cooling steam supply path and a cooling steam discharge path are formed in the dummy ring in the radial direction. Extraction steam or discharge steam of the high-pressure turbine part, whose temperature is not less than that of the steam having passed through a first-stage stator blade, is supplied to the cooling steam supply path. The cooling steam is fed throughout the clearance to improve the cooling effect of the dummy ring and a turbine rotor. The cooling steam is then discharged through a cooling steam discharge path to a discharge steam pipe which supplies the steam to a subsequent steam turbine.

摘要： The apparatus relates generally by using a low pressure kinetic ambient air medium that being drawn in, and then being able to by generating this medium to a very high kinetic moving air pressure. Turning this air speed to form a vortex and then split the air-radiation heat from the cold air stream. The said vortex would then have a temperatures separate effect within its vortex. The said separate effect would separate its air-radiation heat from its air stream. The said separated air-radiation heat would via an adjustable hot outlet valve and would increase its hot heat value output. This apparatus is a non-vapor compression that is the said apparatus uses no refrigerant of any kind. The said air-radiation heat with its increasing heat value output would have a cold water conversion to steam. The said steam is then use to drive a steam turbine producing toque for the user. The said apparatus split-system with its temperatures separation effect would be useful for its non-vapor compression, heating and cooling and refrigeration systems. The said steam would have a steam to warm water conversion and then a warm water-to-steam conversion, therefore commencing cycle thereat.
