摘要： A cascade power system and a method are disclosed for using a high temperature flue gas stream to directly or indirectly vaporize a lean and rich stream derived from an incoming, multi-component, working fluid stream, extract energy from these streams, condensing a spent stream and repeating the vaporization, extraction and condensation cycle.

摘要： A heat transfer system includes a power sub-system configured to receive a heat source stream, and one or more heat exchangers configured to transfer heat from the heat source stream to a working stream. The working stream is ultimately heated to a point where it can be passed through one or more turbines, to generate power, while the heat source stream is cooled to a low temperature tail. A distillation condensation sub-system cools the spent stream to generate an intermediate stream and a working stream. The working stream can be variably heated by the intermediate stream so that it is at a sufficient temperature to make efficient use of the low temperature tail. The working stream is then heated by the low temperature tail, and subsequently passed on for use in the power sub-system.

摘要： A new Kalina thermodynamic cycle is disclosed where a multi-component working fluid is fully vaporized in a boiler utilizing waste heat streams such as flue gas streams from cement kilns so the energy can be extracted from the streams and converted to usable electrical or mechanical energy in a turbine subsystem and after extraction, the spent stream is fully condensed in a distillation-condensation subsystem using air and/or water coolant streams. A new method for implementing the improved Kalina thermodynamic cycle is also disclosed.

摘要： A new thermodynamic cycle is disclosed for converting energy from a low temperature stream from an external source into useable energy using a working fluid comprising of a mixture of a low boiling component and a higher boiling component and including a higher pressure circuit and a lower pressure circuit. The cycle is designed to improve the efficiency of the energy extraction process by mixing the liquid stream from the high pressure circuit with the spent low pressure circuit stream forming a lean system that can be condensed at a low pressure. The new thermodynamic process and the system for accomplishing it are especially well-suited for streams from low-temperature geothermal sources.

摘要： An absorber having a shell, wet tubes and cooling fluid supply and collection portions. Partition walls divide the shell into at least three zones. The wet tubes are disposed parallelly in the shell, passing through the partition walls. The opposite open ends of the wet tube locate in the uppermost and lowermost zones of the shell, respectively. The cooling fluid supply portion communicates with the open end of the wet tube to supply a cooling fluid thereto. The cooling fluid collection portion communicates with the other open end of the wet tube and discharge it outside. A gap is formed between the wet tube and the partition walls facing the intermediate zone. The cooling fluid continuously flows in the wet tubes, while supplying the liquid working fluid to the uppermost zone so as to flow down from the gap. The liquid working fluid flows through the gap to the zone locating below the intermediate zone and is discharged outside. The gaseous working fluid is supplied to the intermediate zone so as to come into contact with the liquid working fluid flowing on the outer peripheral surfaces of the wet tubes.

摘要： A method of operating a power generation system is provided. The system includes a turbine, a regenerative heat exchanger, and a vapor generator. The turbine receives a stream of working fluid and expands the working fluid to produce power. The regenerative heat exchanger has a plurality of condensing heat exchangers which transfer heat from the expanded working fluid to condense the expanded working fluid. The vapor generator vaporizes the condensed portions of working fluid to form the stream of working fluid. In operating the system, a respective portion of the expanded working fluid is directed to each of the condensing heat exchangers, and the amount of condensed working fluid at at least one of the condensing heat exchangers is regulated.

摘要： A method of operating a power generation system is provided. The system includes a turbine, a distiller/condenser, a boiler, and a superheater. The turbine expands a superheated multicomponent working fluid to produce power. The distiller/condenser transforms the expanded multicomponent working fluid into first and second concentration multicomponent working fluids. The first concentration multicomponent working fluid has a first concentration of a component of the multicomponent working fluid. The second concentration multicomponent working fluid has a second concentration of the component which is different than the first concentration. The boiler vaporizes a feed multicomponent working fluid. The superheater superheats the vaporized feed multicomponent working fluid to form the superheated multicomponent working fluid. In operating the system, the temperature of the vaporized multicomponent working fluid is sensed. The first and second concentration multicomponent working fluids are combined to form a third concentration multicomponent working fluid. The third concentration multicomponent working fluid has a third concentration of the component which is different than the first and second concentrations. The third multicomponent working fluid is combined with the vaporized multicomponent working fluid to adjust the temperature of the vaporized multicomponent working fluid and thereby regulate the temperature of the superheated multicomponent working fluid.

摘要： A hygroscopic power plant utilizes low salinity liquid (e.g., sea water having a salinity of about 4%) and a source of high salinity liquid (e.g., brine having a salinity of about 38%) for generating electricity. The plant includes a flash chamber to which liquid is supplied and within which water in the liquid is flashed into steam producing more concentrated liquid. A steam turbine is responsive to the steam for generating electricity and producing heat depleted steam. A condenser is provided to which high salinity liquid and the heat depleted steam are supplied for directly contacting the steam with the high salinity liquid whereby the steam condenses on the liquid producing diluted high salinity liquid. A regenerator is provided for evaporating water from the diluted high salinity liquid to produce the high salinity liquid supplied to the condenser. Apparatus is provided for combining the low sea water liquid with the concentrated liquid produced by the flash chamber to form the liquid supplied to the flash chamber.

摘要： A heat exchanger according to the present invention comprises a housing for containing an upper and a lower layer of fluid, means for preventing intermixing of the two fluids, and heat transfer means for enhancing the transfer of heat between the layers. Specifically, the heat exchanger means is in form of a plurality of elongated cylinders extending into both layers, each of said cylinders containing a convective fluid. Preferably, the convective fluid is a liquid; and the preferred liquid includes water. Where the fluid in each of said upper and lower layers is a gas, the preferred orientation of the cylinders is vertical. The hotter fluid should be beneath the cooler fluid so that heat from the hotter fluid is first transferred to the liquid in the lower ends of each cylinder. The buoyancy of the heated liquid sets up convection currents which carry the heated liquid upwardly in the vertical cylinders where the heat is given up to the cooler fluid. Although a larger heat transfer surface is involved, the material cost of the heat exchanger is relatively low, and a relatively compact heat exchanger results. To further enhance heat transfer, the hotter and cooler fluids should be in counterflow arrangement.
