Patent number: 11306592Abstract: A reverse compression cycle machine includes an evaporator, a compressor and a condenser arranged in series along a path of a working fluid in the machine, further including a boundary layer turbine placed between the condenser and the evaporator. The turbine includes a set of power disks mounted on a shaft which rotates inside a volume of a rotor casing, an inlet opening for introducing a working fluid in a stator volume, a stator nozzle, which accelerates the flow in a direction that is tangential to the power disks, and a discharge of a working fluid. The rotor casing includes a drain of a liquid fraction of the working fluid from the peripheral part of the power disks in order to avoid its concentration in the peripheral part of the volume of the rotor casing.Type: GrantFiled: December 27, 2017Date of Patent: April 19, 2022Assignee: SIT TECHNOLOGIES SRLInventors: Raffaele Antonio Spezia, Alberto Traverso, Stefano Barberis, Luca Larosa, Paolo Silvestri

Publication number: 20180019487Abstract: There is disclosed a method and apparatus for controlling an internal temperature of a fuel cell system. The method and system includes measuring a burner temperature of the high temperature fuel cell system comprising a fuel cell stack and a burner, the fuel cell stack comprising at least one fuel cell. The method further includes comparing the measured burner temperature with a predetermined burner temperature set point to identify a burner temperature difference between the measured burner temperature and the predetermined burner temperature set point and controlling an amount of oxidant supplied to the burner to decrease or increase the amount of oxidant supplied to the burner to thereby reduce the burner temperature difference and control a fuel cell stack inlet temperature.Type: ApplicationFiled: January 26, 2016Publication date: January 18, 2018Inventors: Michele BOZZOLO, Alberto TRAVERSO, Adam PIERCE

Patent number: 8631657Abstract: Thermodynamic cycles with diluent that produce mechanical power, electrical power, and/or fluid streams for heating and/or cooling are described. Systems contain a combustion system producing an energetic fluid by combusting fuel with oxidant. Thermal diluent is preferably used in the cycle to improve performance, including one or more of power, efficiency, economics, emissions, dynamic and off-peak load performance, temperature regulation, and/or cooling heated components. Cycles include a heat recovery system and preferably recover and recycle thermal diluent from expanded energetic fluid to improve cycle thermodynamic efficiency and reduce energy conversion costs. Cycles preferably include controls for temperatures, pressures, and flow rates within a combined heat and power (CHP) system, and controls for power, thermal output, efficiency, and/or emissions.Type: GrantFiled: October 10, 2006Date of Patent: January 21, 2014Assignee: Vast Power Portfolio, LLCInventors: David L. Hagen, Gary Ginter, Alberto Traverso, Bill Goheen, Allan McGuire, Janet Rankin, Aristide Massardo, Ronald L. Klaus
