Abstract: A method is provided for cooling a seal located in a wall of a chamber and through which a movable shaft passes, the seal being heated by hot pressurized vapor that leaks through the seal into the chamber and internal friction. The method comprises the steps of: providing a chamber in which the seal is located and into which the hot pressurized vapor leaks; injecting cool liquid into the chamber in which the seal is located; and cooling and condensing the hot pressurized vapor in the chamber thus cooling the seal.

Abstract: In accordance with the present invention, a method is provided for increasing the output of a geothermal steam turbine power plant comprising the steps of: providing a separate, additional flash separator that produces the steam for operating the non-condensable gas ejector; supplying all the geothermal steam produced by the main high-pressure flash separator to a high-pressure geothermal steam turbine; and whereby high-pressure geothermal fluid is supplied to both said separate, additional flash separator and said main high-pressure flash separator from the same production well in a pumped geothermal system.

Abstract: The present inventive subject matter is thus drawn to a hybrid ultra reliable power generating system for supplying continuous reliable power at remote locations comprising: a primary power unit producing electric power that is supplied to a load. And a secondary power unit in the form of a closed cycle vapor turbine (CCVT) system that is capable of producing 100% of the electric power that is produced by the primary power unit and which is heated in hot standby by rejected heat of the primary power unit, wherein the vaporizer of the CCVT is maintained during hot standby at a temperature above its nominal operating temperature and the vapor turbine of the CCVT is preferable maintained at idle during hot standby at a rotating speed. Preferably, the CCVT includes a burner that combusts the same fuel as the primary power unit and supplies sufficient heat so that the CCVT produces 100% of power produced by the primary unit to the load once the primary power units stops operation.
