Definitions

  • a burner 'unit is provided with a housing in which a plurality of nozzles are removably coupled to a fuel supply. The burner nozzles are mounted in the housing for axial and rotatable movement.
  • FIG. 1 there is shown a burner as- In the operation of large vapor generators, it has be- 5 sembly generally designated by the reference numeral come necessary to employ a burner system having a plurality of nozzles that are capable of being easily adjusted.
  • the fixed type of multi-nozzle gas burners which heretofore have been used do not provide for adjustment of the nozzle, either axially of rotatably with respect to the nozzle axes.
  • the burner assembly of the present invention is capable of being adjusted either axially or rotatably or both axially and rotatably, such that the burner nozzles can be positioned in the most optimum location for reducing vibration and achieving flame stability. Also, it
  • a burner assembly capable of being connected to a fuel supply including a housing for mounting cylindrical burner nozzles.
  • a plurality of cylindrical burner nozzles are movably mounted in the housing.
  • Coupling means capable of being disconplaced in flow communication with the interior of furnace chamber, generally designated 32. f
  • the burner assembly 10 comprises an'outer housing generally designated 34 which is'mounted in the windbox 12.
  • the housing 34 is definedlby a burner barrel 36, a rear end plate 38,'and a front barrel opening 40.
  • a cylindrical wall 42 is secured on the rear end plate v 38 for mounting a circular outer plate 44 to define a nected are .in flow communication between the fuel u supply and the nozzles.
  • Adjustment means for movably mounting the burner nozzles are in the housing to axially move and rotate the burner nozzles after the coupling means have been disconnected. Thus, the burner nozzles can be moved into an optimum position to reduce vibration of the burner nozzles in the housing.
  • FIG. 1 is a front elevational view of a burner assembly with portions being broken away and sectioned to bettershow the adjustment means of the present invenpurge and seal air manifold 46.
  • An air register 50 is mounted in the windbox 12 by means of an air register assembly .52 secured to front wall 16 and an air register back plate 54 which is fixed to burner barrel 36.
  • a central oil gun mounting tube 56 in the form of a cylindrically shaped tube ismounted on the end plate 38 in a fixed position and extends through the housing 34 for mounting an oil gun in the mounting tube 56.
  • theoil gun mounting tube 56' is provided with a removably secured cover plate 58.
  • a plurality of gas guns 60 in the form of cylindrically shaped nozzle. tubes are installed in a plurality of gas gun mounting tubes 62 which are mounted on end plate 38 and are positioned to surround the oil gun mounting tube 56.
  • Each gas gun 60 is defined by a cylindrical wall 64 formed with a rearward opening 66 and a forward exhaust opening 68, with the exhaust opening 68 having aslante'd configuration. It shouldbe noted that the gas gun 60 and the oilgun, which can be positioned in mounting tube 56, can work independently of each other depending on v the mode'of operation required and the only additional equipment required is an ignition means which is well known in the art and hasnot been shown in the drawings for the sake of simplicity.
  • the gas gun mounting tubes 56 Threelegs are provided for mounting the outer v collar 72 to the inner collar 74.

  • the adjustment means 106 comprise two internally threaded holes 108 formed on rear tube 84 engaging a plurality of externally threaded set screws 110.
  • the degree of rotation and axial movement of gas guns 60 can be observed by a fixed post indicator 112 which is welded to rear tube 84 and a movable post indicator 114 which is welded to gas gun 60.
  • the distance between the post indicators 112 and 114 readily shows the axial position of gas guns 60 in the gas gun mounting tube 62.
  • the rotatable alignment of the indicators 112 and 114 shows the degree of rotation of gas gun 60 in mounting tube 62.
  • the rear tube 84 is formed with a counterbored recess 116 for receiving a packing gland 118 and a cylindrical insert 120 integrally formed with a radial shoulder gasket 122.
