20100263380 | CASCADED ORGANIC RANKINE CYCLE (ORC) SYSTEM USING WASTE HEAT FROM A RECIPROCATING ENGINE - A method and system for operating a cascaded organic Rankine cycle (ORC) system ( | 10-21-2010 |
20100285381 | METHOD AND APPARATUS FOR OPERATING A FUEL CELL IN COMBINATION WITH AN ORC SYSTEM - An organic rankine cycle system is combined with a fuel system so as to use the waste heat from the fuel cell to both preheat and evaporate the working fluid in the organic rankine cycle system to thereby provide improved efficiencies in the system. | 11-11-2010 |
20100291455 | INTEGRATION OF AN ORGANIC RANKINE CYCLE WITH A FUEL CELL - An Organic Rankine Cycle system is combined with a fuel cell system, with the working fluid of the Organic Rankine Cycle system being integrated directly into the cooling system for the fuel cell. The waste heat from the fuel cell is therefore applied directly to preheat and evaporate the working fluid in the Organic Rankine Cycle system to thereby provide improved efficiencies in the system. | 11-18-2010 |
20110189001 | ROTATABLE VANED NOZZLE FOR A RADIAL INFLOW TURBINE - A variable nozzle system can comprise a gas inlet ring, an opposing gas outlet ring, an actuation ring, guides, and vanes circumferentially spaced about and disposed between the gas inlet ring and the gas outlet ring. The gas inlet ring, the gas outlet ring, and the vanes can form nozzles, the nozzles being variable by rotation of the vanes about a pivot axis. The plurality of guides can extend from the gas inlet ring, the gas outlet ring, or the actuation ring, and the vanes can be connected to the actuation ring, so that each vane can be rotated by rotation of the actuation ring and by sliding against a respective guide from the plurality of guides. The actuation ring can have a gear rack and can be rotated by rotatable engagement of the gear rack with a pinion attached to the end of a rotatable gear shaft. | 08-04-2011 |
20120299311 | ORGANIC RANKINE CYCLE (ORC) LOAD FOLLOWING POWER GENERATION SYSTEM AND METHOD OF OPERATION - A system for producing power using an organic Rankine cycle (ORC) includes a turbine, a generator, an evaporator, an electric heater, an inverter system and an organic Rankine cycle (ORC) voltage regulator. The turbine is coupled to the generator for producing electric power. The evaporator is upstream of the turbine and the electric heater is upstream of the evaporator. The evaporator provides a vaporized organic fluid to the turbine. The electric heater heats the organic fluid prior to the evaporator. The inverter system is coupled to the generator. The inverter system transfers electric power from the generator to a load. The ORC voltage regulator is coupled to the inverter system and to the electric heater and it diverts excess electrical power from the inverter system to the electric heater. | 11-29-2012 |
20130160449 | CASCADED ORGANIC RANKINE CYCLE SYSTEM - A cascaded Organic Rankine Cycle (ORC) system includes a bottoming cycle working fluid is first evaporated and then superheated and a topping cycle working fluid is first desuperheated and then condensed such that a percentage of total heat transfer from the topping cycle fluid that occurs during a saturated condensation is equal to or less than a percentage of total heat transfer to the bottoming cycle fluid that occurs during a saturated evaporation. | 06-27-2013 |
20130160450 | HEMETIC MOTOR COOLING FOR HIGH TEMPERATURE ORGANIC RANKINE CYCLE SYSTEM - An Organic Rankine Cycle (ORC) system includes a rotor volume at sub-atmospheric pressure, a working fluid sprayed into the rotor volume. | 06-27-2013 |
20130170943 | HYBRID BEARING TURBOMACHINE - A turbomachine includes a housing and a rotatable shaft, where at least a portion of the rotatable shaft is located in the housing. The turbomachine also includes a magnetic thrust bearing that axially positions the rotatable shaft and a radial bearing that centers the rotatable shaft. The turbomachine includes a flexure including a first portion secured to the housing and a second portion axially moveable relative to the first portion. The second portion of the flexure is connected to the radial bearing, and the second portion moves axially to eliminate thrust loads on the radial bearing and allow the magnetic thrust bearing to carry axial loads. | 07-04-2013 |
