    摘要: Power is produced from geothermal fluid containing non-condensable gases whose main constituent is carbon-dioxide. The geothermal fluid is separated into steam and geothermal liquid, the steam being applied to a steam turbine which produces power. The steam exiting the turbine indirectly condensed by an organic fluid liquid which is vaporized and used to run at least one organic vapor turbine for producing power. Organic vapor exiting the organic vapor turbine is condensed and preheated by the steam condensate. Heat extracted from the geothermal liquid is used to run another organic vapor turbine producing power and cooled geothermal liquid which is combined with the cooled steam condensate to form a mixture to which the non-condensable gases are added to form an effluent that is injected into a re-injection well. Carbon dioxide in the non-condensable gases substantially dissolves in the geothermal liquid cooled by the cooled steam condensate reducing the pH of the effluent and thus reducing mineral scale precipitation.

    摘要: A heat exchanger for condensing a vapor containing non-condensable gases comprises an inlet header for receiving said vapor and non-condensable gases, and a plurality of heat exchanger tubes arranged in a plurality of vertically spaced banks. One end of each tube is connected to the inlet header for receiving the vapor and the non-condensable gases in parallel; and the other end of each tube in a bank is connected to a separate header associated with each bank. Each separate header is vented for venting non-condensable gases therein to the atmosphere. The provision of separate headers for each bank of tubes prevents equalization of pressure between the banks thereby preventing back-flow and the creation of pockets of non-condensable gases in the tubes of a bank. Where the banks of tubes are inclined to the horizontal, and the separate headers are elevated above the inlet header, the non-condensable gases in a bank, flow rapidly upwardly into the separate header with which the bank is associated, particularly when the gases are lighter than the vapor. This permits the non-condensable gases to be vented easily as the condensate flows downwardly into the inlet header.

    摘要: Liquid working fluid is drained from the sump of the cannister of a power plant of the type described by transferring the working fluid to the condenser rather than to the boiler. In one embodiment of the invention, liquid in the sump is drained by gravity into an auxiliary boiler which heats the drained liquid producing vapor at substantially the pressure of the condenser; and the resultant vapor is piped directly into the condenser where it condenses and joins the main condensate produced from vapor that has been exhausted from the turbine. In a second embodiment of the invention, the exhaust conduit carrying exhaust vapor from the cannister to the condenser is provided with a loop or elbow that extends below the level of the cannister, and a conduit connects the sump in the cannister to the loop. As a consequence, liquid working fluid in the cannister drains by gravity into the bottom of the loop where it is vaporized or swept by extracting superheat from the exhaust vapor and then returned to the condenser. This arrangement is advantageous in that no additional fuel is utilized to vaporize the drained liquid. Furthermore, the work required of the condenser is reduced because of the reduction in superheat of the vapor entering the condenser.

    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).
