  • Patent number: 6733278
    Abstract: As with most burners and combustors, they utilize fuel and air mixtures. One of the important aspects of burning an air-fuel mixture is that of mixing. Ideally, the fuel should be uniformly distributed throughout the air when ignited. This results in the most complete burn, maximizing beat generation while minimizing unburned and incomplete-combustion products. This disclosure describes an apparatus for enhancing mixing of fuel and air. Combustion air is given a prerotation by passing it through a set of fins before the fuel is injected into the air. Then the mixture is passed through another set of fins, rotating the mixture in a direction opposite that which the air experienced, first.

The improved fuel burner does not result in the use of additional compressors or the introduction of pressurized gases downstream, nor does it require a complex design.

  • Patent number: 6101957
    Abstract: An apparatus for the disposal of solid rocket motors which produce exhaust ases containing flammable and/or explosive products. The solid rocket motor to be burned is first detachably connected to and inserted in one end of an elongated mixing chamber which has, at an opposite end, a multi-step expansion nozzle. The rocket motor is then ignited and the exhaust gas is passed into the mixing chamber, which is sufficiently large to reduce the velocity of exhaust gases from supersonic to subsonic. Air is injected into the mixing chamber to react with flammable and/or explosive products in the exhaust gases and the resultant mixture is then discharged from the mixing chamber through a multi-step expansion nozzle to expand the gaseous mixture and, at the same time, produce substantial turbulence within the gas mixture which is about six times higher than the turbulence levels produced by a constant area circular nozzle.

  • Patent number: 5738281
    Abstract: Use of a shrouding gas to combine with and protect a turbulent gas jet issuing from an orifice enables control of a gas jet stream composition downstream from the orifice. The natural aspiration rate of the gas jet is used to determine the flowrate of shrouding gas which is introduced around the gas jet in a soft gas cushion which does not disrupt the flow pattern of the gas jet but instead is entrained into the jet stream to the exclusion of ambient gases in the atmosphere. Preferably shrouding gas is replaced at least at the rate at which it is entrained. Apparatus for this process uses a porous shroud, preferably of metal foam, through which shrouding gas flows evenly around the gas jet as it issues from a nozzle orifice. Provision for tangential entry of shrouding gas into a manifold which feeds the porous shroud prevents the shrouding gas from impinging upon the porous shroud and causing uneven flow around the gas jet.

  • Patent number: 5681162
    Abstract: A low pressure atomizer is used for the atomization of liquids, such as atomization of fuels found in industrial burners. An atomizer body has an atomizing chamber therein and an annular liquid conduit having an annular diffusion member therein. The diffusion member is shaped to direct liquid passing thereby and into the atomizing chamber and forces the liquid to enter the chamber adjacent the walls thereof. The atomizer body has a first annular gas conduit and a tangential gas port connected between the annular gas conduit and the liquid conduit so that the gas impinges tangentially against the liquid to shear and rotate the liquid entering the atomization chamber. A second annular gas conduit has an angled open into the atomizing chamber to further shear the liquid and gas mixture in the atomizer chamber so that a low pressure atomizer atomizes a liquid with low pressure gas streams.

  • Patent number: 5654040
    Abstract: Methods and apparatus for spraying a liquid or hot melt material involve placing the material in a plurality of parallel grooves arranged across the entire width of a movable member and then causing a compressed gas to impinge upon the material in the grooves, thereby to spray the material from the grooves toward a substrate, as by extending, fiberizing or atomizing the material, or by mixing a gas with the material. For some materials of relatively high viscosity, a scraper is used to scrape the material from the grooves, and the compressed gas impinges the material while it is on the scraper, thereby to cause spraying. This provides a wide band deposition of a liquid or hot melt material with uniform material distribution across the entire width, along with improved ability to quantify the amount of material deposited on the substrate.

  • Patent number: 5647215
    Abstract: A combustor for a gas turbine having primary and secondary combustion zones. The combustor has primary gas fuel spray pegs for supplying a lean mixture of gaseous fuel to the primary combustion zone via a first annular pre-mixing passage and secondary fuel spray bars for supplying a lean mixture of fuel to the secondary combustion zone via a second annular pre-mixing passage. The fuel spray bars are aerodynamically shaped and a row of fuel discharge ports are formed on opposing sides of the spray bar. A pair of mixing fins project outwardly from the spray bar sides. The fins create turbulence in the air flow that ensures adequate mixing of the fuel and air. The fins have sufficient height and are displaced sufficiently far from the fuel discharge ports so that although the turbulence has not dissipated by the time the air flow reaches the fuel discharge ports, the zone of recirculation located downstream from the fins does not extend to the fuel discharge ports.
