Water, Air Or Steam Feeder Spaced From Disperser Patents (Class 431/190)
  • Patent number: 3993431
    Abstract: High-pressure gas generating apparatus includes a combustion chamber and a water jacket surrounding the combustion chamber. A metal fuel injecting nozzle is disposed in the center of one end of the combustion chamber. The water in the jacket is injected into the combustion chamber in the form of a swirling stream around the fuel injected from the nozzle.

  • Patent number: 3982880
    Abstract: In a liquid fuel burner wherein a fuel gasifying member is directly supported by a rotary shaft inserted in a main body of the burner for converting liquid fuel into gasified form, a water evaporation chamber of the annular shape is arranged at the corner of a top portion of the fuel gasifying member and filled therein with a water evaporation promoting material. Water is supplied to the water evaporation chamber and quickly converted into water vapor which is ejected into the fuel gasifying member through steam ejection apertures formed in the water evaporation chamber as the fuel gasifying member is rotated and performs the liquid fuel gasifying function, and the gasified fuel and water vapor form a mixture with air supplied under pressure, the mixture being ejected into the main body of the burner to sustain combustion of liquid fuel in gasified form, so that the consumption of thermal energy can be reduced by using water as part of the liquid fuel.

  • Patent number: 3980416
    Abstract: An oil burner for oil wells in which the oil to be eliminated is admitted to a specially designed sprayer in which its mechanical atomization is brought about by the construction of said sprayer and its pneumatic atomization is effected by means of inputting gas or air under pressure, the atomized product being ignited by means of spark ignitors and the flame produced being protected by a cylindrical casing. Said casing is provided with a front spray ring which injects water into the flame so as to eliminate the formation of black smoke, and a back spray ring for forming a water curtain which protects the platform against heat radiation from the flame.Said burner is mounted on a tubular support permitting its rotation so as to accompany the wind direction.The material combustion capacity of said burner can reach 30 cubic meters an hour, and for higher flow rates, various identical units can be coupled in parallel.

  • Patent number: 3969899
    Abstract: For the purpose of eliminating toxic compounds from exhaust gases emitted from fuel burners, boilers, furnaces and heat engines, an improved fuel burning apparatus is proposed in which fuel is combusted in the presence of a hot mixture of water vapor and oxygen gas produced through catalytic exothermic decomposition of hydrogen peroxide. The fuel burning apparatus will find numerous practical applications, preferred ones of which include provision in steam engines, gas and steam hybrid power plants and turbines.

  • Patent number: 3957420
    Abstract: The invention discloses a low NO.sub.x emission burner for use with an apparatus in which the material or materials are heated by the heat radiated from the radiation surface which is heated by the combustion by the burners. The secondary air injection ports or outlets are so arranged as to inject the secondary air upon the radiation surface to control the combustion, thereby reducing the release of NO.sub.x without producing CO and soot.
