摘要： A closed Rankine-cycle power plant (10) has a boiler (24) for vaporizing an organic working fluid and a first nozzle box (58) for receiving vaporized working fluid from the boiler (24) and for furnishing the fluid to a set of axial flow turbine blades (30) located on the periphery of a turbine rotor (50). The vaporized working fluid from the nozzle box (58) expands on passing through the blades (30) producing work that drives a generator (34) coupled to the turbine (28). A second nozzle box (62) receives vaporized working fluid that exits from the axial flow blades (30) on the rotor (50) and applies the working fluid to a second set of radial flow blades (66) on the rotor (50) adjacent the second nozzle box (62). Working fluid from the boiler (24) is applied directly to the first nozzle box (58), and in a selective, controlled manner, through a proportioning valve (26), working fluid from the boiler (24) is applied to the second nozzle box (62) thereby providing an efficient way to vary the work output of the turbine (28).

摘要： The cooling of a hot fluid is effected using a heat exchanger (11) adapted to receive the hot fluid and liquid coolant for cooling the hot fluid such that the liquid coolant is vaporized. A turbine (12), having an output shaft (19) connected to a fan (18), is responsive to vaporized coolant which expands in the turbine (12) for driving the fan (18) to move a mass of air, and produce vaporized coolant. A condenser (13) receives the expanded vaporized coolant and is responsive to air blown by the fan (18), for condensing the expanded vaporized coolant thereby cooling the same and producing coolant condensate which is then returned to the heat exchanger (11).

摘要： A seal heated by hot pressurized vapor is cooled by providing a chamber in which the seal is located and for containing vapor that leaks thereinto. The pressure in the chamber is reduced by connecting it to a source of low pressure; and liquid is supplied to the chamber at a pressure above the reduced pressure of the chamber and at a temperature below the temperature of vapor leaking into the chamber. The liquid is introduced into the chamber as droplets for contacting vapor that leaks thereinto thereby cooling the vapor and thus cooling the seal. The flow rate of the liquid is adjustable in accordance with the temperature of the liquid in the chamber.

摘要： An energy recovery, pressure reducing system for reducing high pressure gas in a transmission pipeline to a low pressure gas in a consumer pipeline includes an expander system having at least one expander for expanding the high pressure gas and producing work and low pressure gas that is supplied to the consumer pipeline, and a generator coupled to said expander for converting the work to electricity which is supplied to an electrical load. The system further includes apparatus including an on/off valve serially connected to a pressure regulating valve, the apparatus being connected in parallel with the expander system. The on/off valve has an open state for effecting transmission of gas through the pressure regulating valve which has an adjustable flow control opening for throttling high pressure gas and producing low pressure gas when the on/off valve is in its open state; and a closed state for preventing transmission of gas through the pressure regulating valve. A control system is provided which is responsive to flow through the expander system for controlling the size of the flow control opening and the state of the on/off valve.

摘要： Power is produced from high presser geothermal fluid by separating the fluid into high pressure steam and high pressure brine, expanding the high pressure steam in a high pressure turbogenerator for producing power and heat depleted steam, and separating liquid from the heat depleted steam thereby producing dried heat depleted steam at a pressure and temperature lower than the pressure and temperature of the high pressure steam. The liquid so separated, and the high pressure brine are combined in a flash chamber which produces steam which is combined with the dried heat depleted steam and expanded in a lower pressure turbogenerator for producing additional power. Optionally, some of the high pressure steam is used to reheat the dried heat depleted steam and the steam produced by the flash chamber before such steam is expanded in the lower pressure turbogenerator.
