  • Patent number: 7547419
    Abstract: A fluidized-bed reactor for producing hydrogen from methane by steam reforming includes a flow splitter that splits a dense-phase flow of a gas having entrained calcium oxide particles into a plurality of equal flow streams. The reactor also incorporates an orifice plate having at least one high-velocity, rocket-style impinging injector for injecting reactants into the reactor bed. The injector includes a central orifice extending perpendicularly through the plate, and one or more adjacent peripheral orifices that extend through the plate at such an angle that respective streams of reactants injected into the reactor bed through the peripheral orifices impinge on a stream of reactants injected vertically into the reactor bed through the central orifice. The injector cooperates with adjacent base-bleed orifices in the plate to provide a uniform distribution and rapid mixing of the calcium oxide particles with a steam/methane gas mixture across the entire bottom of the reactor bed.

  • Patent number: 6557784
    Abstract: The invention provides a mixer for forming a thin oil film on a surface of a drop of water which can effectively form a drop of water with an oil film. A mixer for forming a thin oil film on a surface of a drop of water is constituted by an oil mist forming chamber for forming an oil supplied from an outer portion in a mist shape by an air stream, a drop of water forming chamber for forming a water supplied from the outer portion by the air stream containing the oil formed in a mist shape in the oil mist forming chamber in a drop of water shape so as to form a drop of water with an oil structured such that a thin oil film is formed on a surface of the drop of water, and a top nozzle for discharging the drop of water with the oil film formed in the drop of water forming chamber to an outer portion. In accordance with the structure mentioned above, it is possible to effectively form the drop of water with the oil film.

  • Patent number: 6547163
    Abstract: A hybrid atomizing fuel nozzle includes a stem with primary and secondary fuel circuits. A nozzle assembly fixed at the downstream end of the stem includes primary and secondary nozzle portions. A shroud and swirler assembly surrounds the nozzle assembly, and includes an annular body with a prefilmer surface. A radial inflow swirler in the annular body directs a first swirling air flow radially inward toward the secondary nozzle portion. An outer air swirler disposed in surrounding relation to the annular body provides a converging second swirling air flow downstream of the prefilmer surface. Discrete fuel passages direct fuel streams outward and downstream toward and against the prefilmer surface. The fuel passes through the first air flow and is evenly distributed across the prefilmer surface in a thin continuous sheet. The first and second air flows then cause the sheet to form a conical spray of atomized fuel.

  • Patent number: 6517010
    Abstract: The system for injecting gas for a detonation projection gun does not incorporate mechanical closing valves or systems for the supply of combustible gas or other inert additive compounds such as nitrogen, argol, helium or the like. On the contrary, the supply of gas or compounds occurs directly and separately to the detonation chamber (1) through a series of independent passages, one for the comburant and at least another passage for the combustibles, each passage being comprised of an expansion chamber (8) and of a plurality of distribution conduits (9) having a reduced cross-section and/or extended length.

  • Patent number: 6389998
    Abstract: A fuel selected from powder fuels and liquid fuel is ejected through a fuel ejection pipe having an annular ejection opening; primary air is ejected through primary air-ejecting openings arranged on outer and inner sides of the fuel ejection, to form outer and inner primary air-ejection straight streams between which the fuel ejection stream is interposed, and to burn the fuel ejection stream. When a powder fuel is used, optionally, a liquid fuel is further ejected and mixed with the above-mentioned primary air streams, and the liquid and powder fuels are burnt together.

  • Patent number: 6375089
    Abstract: A multiple nozzle sprayer that includes a fixed or swing bracket assembly configured with a mounting bracket fixedly or adjustably attached by at least one pivot pin to an outwardly projecting angle arm. The mounting bracket is formed with a mounting pad, and the mounting bracket and the angle arm are each formed with at least one nozzle mounting portion. Also included are first and second nozzles mounted to the nozzle mounting portions and configured to project respective spray clouds to intersect. The first nozzle spray cloud is configured with a predetermined droplet size spectra that is greater than that of the second spray nozzle. The first nozzle can be further configured to spray a cloud of a carrier fluid and the second nozzle can be configured to spray an active fluid in a spray cloud that combines with the carrier fluid spray cloud.
