  • Patent number: 6089219
    Abstract: This application is an invention relating to an improvement in a gas burner for a stove for leading a mixed gas to flame holes, and burning the gas therein, through a gas passage (18) from a mixing tube (5) which produces the mixed gas by mixing a gas introduced in a jet from a nozzle and primary air drawn in with introduction of the gas. A sub-chamber (Ca) is provided separately from the gas passage for storing the mixed gas in a state of flux. The sub-chamber (Ca) communicates with the gas passage (18) through an inlet (3), and discharges the mixed gas stored therein through outlets (2) disposed adjacent the flame holes. With this construction, even when a continued combustion in the flame holes becomes difficult due to air-rich air resulting from an operation of an adjusting lever of the gas burner for a stove to adjusts the quantity of gas rapidly from large to small, the mixed gas stored in the sub-chamber (Ca) is discharged from the outlets (2) to continue the combustion.

  • Patent number: 4938422
    Abstract: An inlet distributor for a gas solids contracting vessel uses a two direction distributor to prevent bed surface disturbances at high inlet velocities and high particle loadings. The distributor uses a series of partitions to peel off portions of the downward gas flow and redirect them radially outward. Each outwardly directed gas flow component passes through a series of perforations to effect any necessary circumferential redistribution before entering the space above the particle bed. By subdividing the gas flow into a number of radially directed flow portions and circumferentially redistributing these flow portions, cross-currents and eddy currents on the catalyst bed surface are minimized or avoided so that disturbances at the bed surface are eliminated. This distributor is particularly effective in vessels having particles loaded to within a short distance of bed inlets and where elbows or other upstream flow devices introduce nonuniformities into the gas flow to a particle bed.

Formation of ice starts from the boundary defining the dry zone, as the dry zone is inherently colder than the area on which water is sprayed, and a solid ice nucleus for propagating ice is formed therein, and proceeds to an ice slab over the whole freezing surface except the dry zone.

  • Patent number: 4582610
    Abstract: A well water aeration system removes volatile contaminants from well water pumped through the well pipe of a well into a building. An elongate spray conduit is spliced into the well pipe at a location below the top of the well but above the average static water level in the well. The spray conduit is formed with spray holes for spraying, aerating and recirculating a fractional portion of the well water pumped through the well pipe with the fractional portion of sprayed water falling back down the well. The spray holes are selected in number and diameter to maintain adequate pressure for continued pumping of the well water through the well pipe. A check valve at the upper end of the spray conduit stops the backflow of water from the building into the elongate spray conduit when pumping of well water through the well pipe stops.

  • Patent number: 4573638
    Abstract: The invention relates to an injection probe, particularly for the sulfur trioxide conditioning of flue gasses, comprising a tubular, closed-end outer casing, a manifold connected to a feed conduit and provided with radially projecting injector tubes, the ends of which project through openings in the outer casing, being disposed within the casing and at least partially surrounded by an insulating material, and a mounting flange connected to the outer casing for attachment of the injection probe. In a known injection probe of this type, employed for injecting sulfur trioxide at a high temperature into a flue gas stream having a lower temperature, there occur considerable heat losses between the supply inlet end of the injection probe and the ends of the injector tubes, resulting in damage to the injection probe, undesirable sedimentation and unsatisfactory operation.

  • Patent number: 4460130
    Abstract: An injector for a high temperature gas distribution means comprising a distribution manifold having a heat-resistant lining with a central passage therethrough, and a refractory-lined injector communicating with the distribution manifold. The injector includes a nozzle disposed external to the manifold having a central opening and an inlet extending from the nozzle to the central passage. The cross-sectional area of the central opening in the nozzle in the direction of flow is smaller at least at one point than that of the inlet such that a major portion of the pressure drop in the gas flowing from the central passage through the inlet and the nozzle is created by the nozzle. By disposing the nozzle external to the distribution manifold, the flow rate of gas through cracks in the heat resistant manifold lining is minimized.
