    摘要: A geothermal power plant operating on high pressure geothermal fluid includes a primary separator for separating the geothermal fluid into two channels, one containing high pressure steam and the other containing high pressure liquid. A primary steam turbine in the high pressure steam channel is responsive to high pressure steam for generating electricity and producing heat depleted high pressure steam. A secondary separator separates the heat depleted high pressure steam into a steam component and a liquid component. A primary heat exchanger is responsive to the high pressure liquid and the steam component for transferring heat to said steam component thereby producing low pressure steam and cooled high pressure liquid. At least one power plant module includes a low pressure steam turbine responsive to the low pressure steam for producing electricity and heat depleted low pressure steam; a condenser/vaporizer containing an organic fluid for receiving the heat depleted low pressure steam and converting it into condensate, and for vaporizing the organic fluid; an organic vapor turbine responsive to vaporized organic fluid produced by the condenser/vaporizer for generating electricity and for producing heat depleted organic fluid; a condenser for condensing the heat depleted organic vapor into a liquid; a preheater for heating the liquid; a pump for returning heated liquid from the preheater to the condenser/vaporizer; and a conduit for directing condensate from the condenser to the preheater.

    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.
