  • Patent number: 11098649
    Abstract: High-pressure fan duct bleed air is used to pressurize a cavity between the fan duct inner wall and the inner wall thermal insulation blankets. The cavity is pressurized to prevent hot air from the nacelle core compartment from flowing under the insulation blankets and degrading the fan duct inner wall. Pressure regulating valves (PRV) allow better control of the cavity pressure during different phases of the flight profile and under different levels of insulation blanket seal degradation by passively controlling exit area from the cavity based on an established pressure limit. Moreover, the pressurization system can be implemented as a passive cooling system by increasing the mass flow rate into the cavity and then the core compartment to a level suitable for core compartment cooling.

  • Patent number: 11028752
    Abstract: A reductant insertion assembly comprises a reductant bladder defining a bladder internal volume for holding a reductant. The reductant bladder comprises a bladder inlet and a bladder outlet. A pressure sensor is positioned downstream of the bladder outlet. The pressure sensor is operable to sense a pressure of the reductant downstream of the reductant bladder, and generate a pressure signal indicative of the pressure. A compression mechanism is operably coupled to the reductant bladder. The compression mechanism is configured to selectively exert a compressive force on the reductant bladder so as to expel the reductant therefrom via the bladder outlet. The compression mechanism exerts the compressive force in response to the pressure signal.

  • Patent number: 8650876
    Abstract: Ammonia sometimes present in geothermal steam increases the solubility of hydrogen sulfide in the steam condensate produced by the surface condenser in a steam cycle geothermal power generating unit by reacting with the hydrogen sulfide to produce nonvolatile ammonium bisulfide. The condenser vent gas also produced contains carbon dioxide. Contacting the steam condensate with the condenser vent gas at a pressure slightly greater than atmospheric causes carbon dioxide to dissolve in the condensate, decreasing pH and converting bisulfide ion back to hydrogen sulfide. Subsequently exposing the acidified condensate to condenser vacuum strips the hydrogen sulfide from the condensate, eliminating the need for further chemical treatment of the condensate to prevent air pollution. Hydrogen sulfide partitioning performance is further improved by converting the hydrogen sulfide in the vent gas to sulfur dioxide before contacting it with the condensate.

    Abstract: Turbine exhaust steam, axially fed between counter-rotating radial flow disk turbines, separates into: (1) a radially inward flow of low enthalpy dry steam, and (2) a radially outward flow of high enthalpy steam, noncondensibles, and condensate. The radially inward flow goes to a conventional condenser. The radially outward flow loses enthalpy turning the disk turbines as it passes in the boundary layers against the disks, thus becoming low enthalpy dry steam, and the counter-rotation of the disks by impinging mass flow of condensate, high enthalpy steam, and noncondensibles sustains a cascade of dynamic vortex tubes in the shear layer between the boundary layers. The low enthalpy dry steam resulting from work being done flows into the condenser through the vortex cores of fractal turbulence. Condensate exits the periphery of the workspace, ready to be pumped back into the Rankine cycle. More condensate is recovered from the low enthalpy vapor in the condenser.

  • Patent number: 7926277
    Abstract: Disclosed is a method for operating a condenser of the type having a housing inside of which is disposed a bundle of water tubes, a steam inlet for steam to flow inside the housing for contacting the tube bundle for cooling, and having a stagnant air zone during operation wherein any air in-leakage preferentially collects and condensate in the air zone becomes subcooled. A trough or drain is placed beneath the stagnant air zone for collecting subcooled condensate from the stagnant air zone. Collected subcooled condensate is transported from the trough or drain in a pipe to said steam inlet. The transported condensate is injected with an injector for contacting with steam entering the condenser, whereby the injected condensate is heated by the steam for expelling dissolved oxygen in the injected condensate. Advantageously, the condenser is fitted with an array of temperature sensors at the stagnant air zone for determination of its presence and/or size.

  • Publication number: 20110067410
    Abstract: A reformation power plant generates clean electricity from carbonaceous material and high pressure CO2 which can be easily sequestered or utilized for a beneficial purpose, such as fuel production. The reformation power plant design utilizes a reformation process that reforms carbonaceous fuel with super-heated steam into a high-pressure gaseous mixture that is rich in carbon dioxide and hydrogen gas. This high-pressure gas exchanges excess heat with the incoming steam from a boiler and continues onward to a condenser. Once cooled, the high-pressure gas goes through a methanol separator, after which the CO2-rich gas is sequestered underground or beneficially re-used. The remaining hydrogen-rich gas is combusted through a gas turbine. The gas turbine provides power to a generator and also regenerative heat for the boiler. Finally, the generator converts mechanical energy into electricity, which is transferred to the electric grid.

  • Patent number: 7895839
    Abstract: A combined circulation condenser for a steam cycle apparatus is disclosed. The steam cycle apparatus includes a steam generator with a port for receiving a fluid. The steam generator presents heat to the fluid to generate steam that is directed out another port, which presents the steam to a turbine to generate electrical power. The turbine has an outlet that directs an exhaust steam into a condenser. A fluid flow system is inside the condenser, which directs cooling water along a pathway through the condenser so that the cooling water cools the exhaust steam, forming condensate. A condensate pump collects and pumps the condensate along another pathway through the condenser so that the condensate can additionally cool the exhaust steam. Simultaneously, the exhaust steam warms the condensate. This pathway directs the condensate to a feed pump, which pumps the condensate back to the steam generator through the generator's input port.

  • Publication number: 20100219805
    Abstract: An electrical power boosting apparatus includes a metal substrate having a monomolecular carbon-based film on first and second surfaces, a conductive core, a positive electrode at one end, and a negative electrode an opposite end and magnets positioned adjacent and in a spaced-apart relationship to the metal substrate, the magnets are oriented so that north and south poles of each magnet are matched with opposite poles of an adjacent magnet. Electrical power is boosted by passing an initial electric current having an initial voltage through the conductive core of the metal substrate and causing or allowing an interaction between the metal substrate, the monomolecular carbon-based film, and the magnets to produce a modified electric current having a final voltage that is greater than the initial voltage.

  • Publication number: 20100071370
    Abstract: Raw MSW is delivered through an organic digester (12) within which an organic fraction of the MSW is broken down by a combination of aerobic microbial activity and mechanical action and converted into a solid bio fuel material. Treated waste material comprising a mixture of the solid bio fuel material and insert inorganic waste material is discharged from the digester (12). The treated material is delivered through a separator (20) for removal of the inorganic fraction. A substantially homogenous solid bio fuel material is discharged from the separator (20), and passed through a dryer (26) and into a gasifier (30). Within the gasifier (30) the homogenous solid bio fuel material is heated in a depleted oxygen atmosphere to generate a bio fuel gas rich in methane, hydrogen and carbon monoxide. The bio fuel gas is delivered through a cleaner (35) and then collected in a storage tank. Bio fuel gas is fed as required from the storage tank to a power plant (50) for generating electrical energy.
