Definitions

  • BURNER NOZZLE TIP 2 3 Drum! ABSTRACT A fuel burner is provided in which the nozzle tip [52] [1.8. CI 431/114, is formed with a frustoconical end wall integrally connected to 239/549, 239/558, 239/559 a cylindrical outer wall and the walls have a common central [5
  • the outer walls are formed with a series of orifices which [50] Field of Search 431/1 14, comprise equally spaced apart rows of orifices, positioned in straight lines that are parallel to the central axis ofthe walls.
  • BURNER NOZZLE TIP BACKGROUND OF THE INVENTION In the operation of power-generating systems it is important to obtain uniform burning of the fuel in is burner section of the steam generator. Accordingly, it has been common practice to mount a series of burners along the periphery of the furnace.
  • One of the more common type of burner systems is the combined oil and gas fired unit in which oil is fed through the center of the burner and gas is fed through a coaxial, annular outer chamber.
  • the gas-firing system has presented a problem in that severe vibration has been experienced during normal operating conditions. This vibration generally occurs close to burner tip, it is possible to counteract the vibration.
  • the outer orifices of the present invention result in the ignition point of the gas being brought back closer to the surface of the nozzle tip, and the center of the flame becomes much richer.
  • a sufficient change occurs in the initial combustion zone of the flame to radically change the resonant frequency of the flame and thereby reduce the vibration created by the burner.
  • the end wall has a series of end orifices which have axes that are substantially perpendicular to the plane of the end wall.
  • the outer wall is formed with a series of outer orifices which have axes that are substantially perpendicular to the plane of the outer wall.
  • means for introducing a combustible gas to the annular chamber and means for igniting the gas passing through the orifices.
  • FIG. I is a perspective view of a gas burner in which the nozzle tip of the instant invention is employed
  • FIG. 2 is an enlarged elevational view of the nozzle tip removed from the burner shown in FIG. 1. with portions being broken away and sectioned to illustrate the axes of the end orifices and outer orifices of the nozzle tip;
  • FIG. 3 is an enlarged elevational view of a portion of the burner shown in FIG. i with portions broken away and sectioned to show connection of the nozzle tip to the burner.
  • a fuel burner generally designated by the reference numeral which is shown completely removed from its operating environment in a vapor generator.
  • the means for introducing a combustible gas into the burner 10 has been shown schematically by an arrow which is designated G and likewise the means for introducing oil through the center of the burner 10 is shown by an arrow which is designated by the letter 0.
  • the means for igniting the gas, as well as the means for igniting the oil are not directly shown in the drawings, as these are well known in the art.
  • the burner 10 includes a cylindrical conduit 12 which is coaxially mounted in a cylindrical guide tube 14, with a flange port I6 being connected in flow communication at the end of the conduit 12 for receiving the gas 0.
  • An end port 18 is gas G exteriorally drawings.
  • the conduit [2 includes a cylindrical inner wall 20 spaced apart from an outer wall 22, with walls 20 and 22 being joined together by a nozzle tip 24 to form an annular gas chamber 26.
  • the nozzle tip 24 includes a frustoconical end wall 28 which is integrally formed with a cylindrical outer wall 30, and a cylindrical inner wall 32.
  • the walls 30 and 32 are joined together by welds 34, thereby completing the annular gas chamber 26.
  • the inner walls 20 and 32 define an inner guide conduit 36 which is connected to the end port 18 for passing the oil gun 0 through the burner.
  • the frustoconical end wall 28 is formed with a series of end orifices 40 which have axes that are substantially perpendicular to the plane of orifices 42 which have axes that are substantlally perpendicular to the plane of the outer wall 30.
  • the axis of outer orifice 42 which is designated A-A is not parallel to the axis of end orifice 44 which is designated B-B.
  • the angle subtended between axis A-A and B-B, which has been designated 8 is less than
  • the end orifices 40 and outer orifices 42 are formed in rows which are designated 50 and are positioned along the outer surface of end wall 28 and outer wall 30, parallel to the central axis of cylindrical conduit 12.
  • a fuel burner capable of combusting a fuel comprising a conduit including an inner tube wall and spaced apart essentially uniform outer tube wall joined together at a tip section section including a frustoconical end wall section integrally connected to a cylindrical wall section, said end wall section having a series of end orifices which have axes that are substantially perpendicular to the plane of said end wall section, said cylindrical wall formed with a series of outer orifices which have axes that are substantially perpendicular to said central axis, said end orifices and outer orifices forming rows of orifices including at least one of said end orifices and at least one of said outer orifices and said rows of orifices being positioned in straight lines along the outer surface of said conduit, parallel to said central axis, and said rows of orifices being equally spaced apart along the periphery of said conduit and means for introducing said fuel to said gas chamber, such section slopes inwardly from said cylindrical wall section such that an angle is
