  • Patent number: 8559101
    Abstract: A reflective plate 72 is arranged so as to reflect infrared rays, radiated from a heating wire 71, outside of a heater 70 and may be made of steel. A number of cavities 73 are arranged on the surface of the reflective plate 72. Since the cavities 73 have an aspect ratio of 0.17 to 0.7, the infrared reflectance can be increased compared to a reflector with no cavities.

  • Patent number: 7631640
    Abstract: A highly efficient radiant burner assembly (100) for use in a patio heater or the like in areas where people prefer or require low NOX emissions. The efficiencies are created through the use of a spherical burner element (116) that is either formed of a high temperature steel wire mesh or stamping containing apertures of a predetermined size to allow combustion to remain within the burner element and to not cause the temperature of the burner element to exceed the temperature at which NOX are developed. Coating the burner with a catalyst also aids the low emission combustion process. Additional efficiencies are provided by atomizing the fuel before it is mixed with air and by the use of a laminar flow heat exchanger (940) that utilizes a fluid media flowing in a helical coil condenser unit.

  • Patent number: 6683243
    Abstract: Multilayer coating designs have been developed to provide selective emission for a molybdenum thermophotovoltaic (TPV) radiator surface. These coatings increase the surface emissivity of a molybdenum TPV radiator substrate in the wavelength range that matches the bandgap of the TPV cells to increase the power density of the TPV system. Radiator emission at wavelengths greater than the bandgap energy of the TPV cells is greatly reduced through the use of these coatings, which significantly increases the efficiency of the TPV system. The use of this coating greatly improves the performance of a TPV system, and the coating can be tailored to match the bandgap of any practical TPV system.

  • Patent number: 6489553
    Abstract: Our cylindrical TPV generator uses low bandgap PV cells mounted on circuits in a polygonal array around an IR emitter. The combustion gases are completely contained within the radiant tube burner. The PV array is mounted inside a leak-tight envelope cooled on its outer surface by either water or air flow. Flanges on either end of this PV array container allow for hermetic seals. A folded back coaxial emitter support tube provides a long path length limiting thermal conduction along its cylindrical wall from the very hot emitter section to the cooled seal flange. In our improved cylindrical TPV generator, we provide for a low temperature catalytic after-burn by providing a perforated turnaround plate coupling between the inner disk stack and the outer disk stack. This perforated turnaround plate provides a small amount of combustion air for the after-burn. A catalyst coating can be provided on the hotter surface of the outer finned disks. The after-burn occurs in the outer finned disk stack.

  • Patent number: 5383976
    Abstract: Multiple low bandgap GaSb photovoltaic cell strings are mounted around the perimeter of a cylinder in parallel with the cylinder axis. These cell strings face radially inward and receive infrared (IR) radiation from a ceramic axial emitter and efficiently convert this radiation into DC electric power. Linear reflectors are associated with each cell string and serve to concentrate IR energy into the photovoltaic cells or to return it to the emitter. The ceramic emitter is heated from the inside by hydrocarbon combustion. A uniform temperature along the length of the emitter is maintained by staged addition of fuel in a special burner design. Regenerative air heating is also inherent in the burner design increasing its efficiency. Air for the combustion is supplied by a blower. Sliding contacts to the rotating shaft on the blower can be used for DC to AC conversion. The cell strings are cooled through a compact closed cycle convective liquid cooling loop.

  • Patent number: 5356487
    Abstract: A combustion device for producing predetermined radiation spectral output and heat for a variety of applications including lighting, cooking, heating water, electric power generation, and providing inexpensive photons to enhance chemical and physical reactions.A process for the preparation of a porous ceramic burner is described which comprises drawing a solution which contains metal oxide fibers onto a burner skeleton by use of a vacuum to form a base fiber layer. The base fiber layer is dried, after which an additional metal oxide fiber layer, the outer fiber layer, is added over the base fiber layer. In another embodiment of the invention, an intermediate fiber layer is placed over the base layer, prior to the addition of the outer fiber layer.

  • Patent number: 5312521
    Abstract: Multiple low bandgap Ga.sub.1-x In.sub.x Sb photovoltaic cell strings are mounted around the perimeter of a cylinder parallel to a central cylindrical emitter, or radiator. These cell strings face radially inward to receive infrared (IR) radiation from the emitter, and efficiently convert this radiation into DC electric power. Reflecting surfaces are positioned on either side of each cell string to concentrate most of the IR radiation on the photovoltaic cells and return much of the balance to the emitter. The inside of the emitter is heated by flames from small gas jets from a central burner tube with a jet pattern somewhat similar to that of a gas kitchen stove. A uniform temperature along the length of the emitter is maintained by employing a gas jet hole pattern that produces a staged addition of fuel in a special burner design. Regenerative air heating is employed to increase the flame temperature and avoid large energy losses in the stack gas.

  • Patent number: 5240407
    Abstract: A process for producing a sturdy refractory metal oxide article includes the steps of heating a substrate of organic material impregnated with a metal compound to thermally decompose the compound without substantial thermal decomposition of the substrate, further heating to decompose and remove the organic material and complete conversion of the compound to a metal oxide so that a metal oxide replica of the substrate remains and further heating to sinter and densify the replica such that the replica has a strength (shock resistance) figure of merit of at least three g-meters and the replica retains such strength after heating to 1500 C.
