    Abstract: A radiant tube heater has a tubular arrangement with an air duct portion forming a combustion air passage and a radiant tube portion which is heated by and surrounds a laminar flame. An inlet end of the air duct portion receives combustion air from a blower. A burner assembly mounted in the air duct portion includes a burner nozzle and a burner head for mixing gas and combustion air, this head having an inlet portion and an outlet portion wider than the inlet portion. A perforated restricting plate is mounted in the air duct portion and extends around the burner head. Air holes in this plate are sized and distributed so that the plate increases flow of combustion air through openings formed in the side of the inlet portion and allows combustion air to flow in the annular passage between the outlet portion and the air duct portion.

    Abstract: A process and apparatus is provided for enhancing the formation of a uniform population of hollow glass microspheres. A burner head is used which directs incoming glass particles away from the cooler perimeter of the flame cone of the gas burner and distributes the glass particles in a uniform manner throughout the more evenly heated portions of the flame zone. As a result, as the glass particles are softened and expand by a released nucleating gas so as to form a hollow glass microsphere, the resulting hollow glass microspheres have a more uniform size and property distribution as a result of experiencing a more homogenous heat treatment process.

  • Patent number: 6887073
    Abstract: A damper for a burner includes a gate plate that moves generally parallel to the inlet of a blower housing of the burner. The gate plate rotates parallel to the inlet and is sized and positioned so that it can rotate between a position completely covering the inlet and a position leaving the inlet completely uncovered. A seal assembly between the gate plate and the inlet substantially seals a gap between the gate plate and the inlet. An actuator moves the gate plate automatically to close the damper or open the damper to any of a plurality of open damper positions.

  • Patent number: 6877978
    Abstract: A miniature combustor comprising a combustion chamber having at least one critical dimension that is sub-centimeter. Combustion is confined within the chamber by injecting a liquid fuel as a film over substantially the entire area of the chamber walls. In a preferred embodiment, a swirl or vortex generator may be included at the entrance of the chamber to cause the in-flowing oxidizing gases to swirl within the chamber. The liquid fuel may be applied as a film through one or more orifices or a porous wall material, or may be applied by spraying the fuel on a surface within the chamber. The liquid fuel may be augmented with an inert liquid such as water.

  • Patent number: 6872070
    Abstract: A U-tube diffusion flame burner assembly having improved flame stabilization with no undesirable acoustic effects. The burners are axial units comprised of flame holders and combustors. The flame holders includes secondary air tubes to support the flow of secondary air that have helical walls forming helical passageways along at least a portion of its inner diameter to impart a swirl to the secondary air. The helical passageways impart a swirl to the secondary air exiting the passageways while simultaneously acting as a heat exchanger to heat primary air. The flame holders includes fuel tubes having first ends connected to a fuel supply and second flame ends. A plurality of radially oriented apertures are located at the second flame ends to distribute fuel in a radial direction. Primary air tube surrounds at least the flame ends of the fuel tubes and extend axially from first air supply ends to second flame ends.

  • Publication number: 20040197721
    Abstract: A novel safety stopper for use with a conventional welding torch striker includes a sleeve made of a flexible, non-flammable, heat-resistant material. The sleeve is shaped to enclose a central portion of both arms of a conventional welding torch striker, while allowing relative movement first and second push-tabs. The sleeve is retained on the arms by spring force. The sleeve is shaped to cover a substantial portion of the open area defined by the arms and the strike plate, while exposing the strike plate and the flint. A novel welding torch striker includes an integral safety stopper made of a flexible, non-flammable, heat-resistant rubber and formed as a web, a first handle-grip, and a second handle-grip. The stopper extends between both arms of the striker with the first handle-grip surrounding a portion of the first arm and the second handle-grip surrounding a portion of the second arm.

  • Publication number: 20040191142
    Abstract: The present invention provides a burner for use in a combustion-type waste gas treatment system for combusting waste gases emitted from semiconductor manufacturing system, particularly, a deposition gas containing SiH4 and a halogen-base gas, simultaneously at a high efficiency of destruction, making it difficult for a powder of SiO2 to be attached and deposited, performing a low-NOx combustion, and maintaining a desired level of safety. The combustion-type waste gas treatment system has a flame stabilizing zone (15), which is open toward a combustion chamber (11), surrounded by a peripheral wall (12), and closed by a plate (14) remotely from the combustion chamber. A waste gas, an auxiliary combustible agent, and air are introduced into and mixed with each other in the flame stabilizing zone (15), and the mixed gases are ejected toward the combustion chamber (11) perpendicularly to the plate (14).

  • Patent number: 6780004
    Abstract: A thermal post-combustion device for the purification of exhaust air comprises an outer housing surrounded by an insulating jacket, a combustion chamber bounded by a combustion chamber housing and arranged within the outer housing, and a burner chargeable with fuel and that comprises a burner nozzle and a first flame tube that surrounds the burner nozzle and connects the space between the outer housing and the combustion chamber housing to the combustion chamber. The burner includes at least one further flame tube that is arranged completely within the combustion chamber, and the end of the first flame tube lying inside the combustion chamber is surrounded by a further flame tube of larger radius so as to form an annular gap between the first flame tube and the further flame tube.
