  • Patent number: 4257338
    Abstract: Novel solid fuel combustion and heat transfer geometry/process and illustrative embodiments, which include log burning space heaters, a boiler and a hot air heat exchanger are described. The illustrative boiler embodiment depicts a standard module that when joined with other similar modules makes the construction of any size boiler possible. The combuster is designed to burn nearly any solid fuel, depending on price and availability, and also incorporates an auxilliary fuel oil combuster to either aid in the combustion of certain solid fuels or to convert over entirely to fuel oil. This novel geometry/process consists of solid fuel dispersed over two nearly intersecting surfaces with a third adjustable surface introduced to provide control of the combustion rate by a mutual radiant feedback. The fuel retaining surfaces are so constructed and positioned to enhance radiant heat interchange which maintains highest combustion temperatures along fuel surfaces that are directed toward the heat absorbing medium.

  • Patent number: 4255122
    Abstract: A burner pumps fuel through a fuel line and pumps air into a chamber. Air from the chamber and fuel from the fuel line enter a mixing chamber. The fuel and air mixture flow through an evaporator tube which extends into a combustion chamber and turns at two successive 90.degree. angles and releases the mixture in an opening facing the bottom of the chamber. Combustion air flows through the air chamber outward parallel to the combustion chamber walls in a labyrinth and then into an expansion chamber through air slots and past flow directing wings which give the combustion air a screw direction. Exhaust gas flows outward around the outer walls of the labyrinth. The evaporator tube has an outer area to inner volume ratio of 0.3 to 0.8.

  • Patent number: 4255121
    Abstract: This invention is directed to a gaseous fuel containing water produced by a process, wherein a mixture gas of water, fuel and air is swirled with intense friction between them, contacted with metallic elements to receive thermoelectrons and activated at a temperature about 100.degree.-600.degree. C., as well as a process and apparatus for producing said fuel. When the gaseous fuel containing water by this invention is burned, the calorific value is greater than that of pure fuel combustion and the discharge of NO.sub.x and CO from the exhaust gas is small.

  • Patent number: 4253818
    Abstract: An igniting device wherein an elongated and hollow tubular body member is fixed at one longitudinal end to a gasifiable fuel container, a rotary member having an axial shaft extended at an end to the other extended end of the body member is rotatably born adjacent the fixed end of the body member, and gasified fuel discharged at the extended end of the body member is ignited by a flame generating means which cooperates with the extended end of the shaft of the rotary member. The flame generating means thus disposed at a remote end from the fuel container utilized as gripping part of the device enables it possible to ignite easily and reliably even burners located relatively deeply inside gas equipments.

  • Patent number: 4250868
    Abstract: A control system adapted to be secured to a solid fuel burner, such as a fireplace or a stove, to create and regulate forced fluid heat exchange and forced draft in the burner. The system comprises an electrical draft inducer/damper mounted in the burner flue, a fluid heat exchanger mounted over the burner firebox, and a control apparatus capable of deactivating the draft inducer/damper and the heat exchanger, automatically damping the flue, when combustion in the burner subsides. The control system, including the draft inducer/damper and heat exchanger, may be incorporated with a solid fuel burner, thus comprising a heating system.

  • Patent number: 4249885
    Abstract: An atomizing nozzle particularly suited for your use in compact combustion chambers. Successful combustion of liquid fuels having generally high viscosity and widely varying properties such as distillation temperatures, distillation rates and impurities, including "heavy" and waste oil. Improved combustion is accomplished through the use of viscosity control and improved fuel atomization. Use of a nozzle utilizing "shearing" of the fuel by an atomizing fluid stream which intersects the fuel at approximately right angles. Recombination of liquid fuel particles is prevented by the use of a controlled "exit orifice" in the burner nozzle. The nozzle also features continuous circulation of the fuel in the nozzle body which establishes orientation of impurities contained in the fuel relative to the exit orifice so that they are expelled through the orifice. Combustion of conventional distillate fuel oil such as API No. 1 and 2 is also provided.

  • Patent number: 4249517
    Abstract: A composite glass and molded frame member. In a specific embodiment, one or more glass panels may be utilized in association with a generally U-shaped elastomeric packing and mold-piece seal strip with thin leg portions engaging the glass. The strip has a collapse or compression zone formed outboard and adjacent the edge portion of the glass to accommodate, inter alia, differing thermal expansions and contractions of the glass and the frame. The glass edge and strip are unitary with a perimeter frame of urethane plastic material which is molded over the glass edge and seal. The mold pieces of the molding apparatus have continuous raised or ridge portions adapted to engage the leg portions of the elastomeric strip on either side of the glass panel to prevent flow of plastic material over the glass surface area encircled by the ridge portions of the mold pieces.

  • Patent number: 4246886
    Abstract: Freeze protected hot water solar heating apparatus for providing room heating and domestic hot water service comprising a solar heat collector, a water storage tank, a freeze protector, a fuel burning boiler, a heat exchanger, in-line sensors, and pumps for circulating the water. The freeze protector is in heat transference contact with the flue of the boiler. The freeze protector, controlled by a temperature sensor, prevents freezing of the water in the solar collector and additionally utilizes waste heat from the flue of the boiler to heat water anytime the boiler is in operation. The boiler is activated, upon the water in the water tank falling below a predetermined temperature. A thermostat controlled fan forces air over the heat exchanger to provide room heating. Check valves are provided for preventing back flow of water from the solar collector. The apparatus may also contain a heat pump having its heat transference coils adjacent to the heat exchanger for full utilization of forced air from the fan.

  • Patent number: 4243021
    Abstract: The panel for converting solar energy to sensible heat of a working fluid comprises a thermally-insulated and impervious base member overlayed with and spaced from a solar-collecting member or collector. The collector is in turn overlayed with and spaced from a pair of mutually spaced impervious films which are essentially transparent to incident solar radiation and substantially opaque to radiation emitted by the collector. The solar-collecting member consists of a thermally-insulating porous matrix substance and of a second substance affixed thereto. The second substance is in divided and substantially discrete form. The second substance exhibits a high degree of absorptivity for solar radiation and low emissivity for long wave radiation. The working fluid to be heated is admitted to a chamber underneath the solar-collecting member. The working fluid has a pressure sufficient to cause it to percolate through the collector.
