    摘要： Method and apparatus for cooling and recirculating oxidant to the cathode of a fuel cell stack. Heat energy is removed from the fuel cell stack through utilization of excess air or other oxidant relative to the stoichiometric amount for reaction with a hydrogen-containing fuel. Reaction products, including excess air and water, flow to a nozzle upstream of a flow constricting venturi. A coolant, such as liquid water in a fine spray form, is injected through the venturi and draws the reaction products through the venturi. The mixing of the coolant and the reaction products results in a condensation of the high temperature reaction product water vapor and further dehumidification of the reaction products takes place in a passive separator such as a demister. Coolant is injected into the venturi in sufficient quantity to develop the pressure head necessary to recirculate the cooled and dehumidified air through a conduit system and back to the fuel cell stack. A supply of makeup air is also provided. Coolant and water collected in the passive separator can also be recirculated for injection through the venturi.

    摘要： Steam turbine power plants employ condensers for condensing the dead steam of the turbine. The required cooling in the condenser is obtained by cooling water which is, in case of dry cooling towers, injected into a mixing condenser. Recooling of the cooling water is obtained in surface heat exchangers of the dry cooling tower which carry off the heat by means of air.Where the employment of such system is jeopardised by the hazards of climatic conditions, it is suggested to associate water cooled heat exchangers with the surface heat exchangers and the dry cooling tower of the system. Such water cooled heat exchangers serve as auxiliary means where the cooling effect of the surface heat exchangers of the dry cooling tower fails to ensure a desired low condensation temperature in the mixing condenser.

    摘要： THE DISCLOSURE CONCERNS A POWER CONVERSION SYSTEM FOR CONVERTING HEAT ENERGY TO ELECTRICAL POWER, WHEREIN THE POWER CONVERSION SYSTEM INCLUDES A SO-CALLED JET CONDENSER CONNECTED TO THE EXHAUST OUTLET OF A TURBINE WHICH DRIVES AN ELECTRIC GENERATOR, SUCH AS AN ALTERNATOR, IN PRODUCING ELECTRICAL POWER. THE POWER CONVERSION SYSTEM COMPRISES A CLOSED RANKINE CYCLE EMPLOYING AN ORGANIC WORKING FLUID. THE SINGLE WORKING FLUID AFTER BEING HEATED TO ITS VAPORIZED PHASE DRIVES THE TURBINE TO GENERATE ELECTRICAL POWER AND IS DISCHARGED FROM THE EXHAUST OUTLET OF THE TURBINE IN ITS VAPOR PHASE FOR ADMISSION INTO THE CONDENSER. A JET STREAM OF COOLED WORKING FLUID IN ITS LIQUID PHASE IS INJECTED INTO THE JET CONDENSER TO MIX WITH THE VAPORIZED WORKING FLUID COMING FROM THE EXHAUST OUTLET OF THE TURBINE. THE MIXING OF THE COOLED LIQUID WORKING FLUID WITH THE VAPORIZED WORKING FLUID CAUSES RAPIE CONDENSATION OF THE VAPORIZED WORKING FLUID FOR REUSE IN THE SYSTEM CYCLE, WHILE PROVIDING FOR A REDUCTION IN THE TURBINE

    BACK PRESSURES WHICH ARE CRITICAL TO THE EFFICIENCY OF THE SYSTEM SO AS TO IMPROVE ITS EFFICIENCY IN PRODUCING AN ELECTRICAL OUTPUT FROM A SUITABLE HEAT SOURCE. THE HEAT SOURCE EMPLOYED WITH THE SYSTEM MAY COMPRISE NUCLEAR ENERGY, SUCH AS HEAT ENERGY FROM NUCLEAR REACTORS OR RADIOACTIVE ISOTOPES, OR CHEMICAL HEATING, SOLAR ENERGY, OR OTHER HEAT SOURCES WHICH ARE CAPABLE OF HEATING A WORKING FLUID IN ITS LIQUID PHASE IN A BOILER PRIOR TO ADMITTING THE WORKING FLUID AS A HEATED VAPOR INTO THE TURBINE FOR DRIVING THE TURBINE BLADES AND PRODUCING ELECTRICAL ENERGY THROUGH AN ALTERNATOR OPERATED BY THE ROTATING SHAFT OF THE TURBINE.
