Definitions

  • ABSTRACT A gas burner comprising a row of a plurality of gas nozzles coupled to a common gas supply and a plurality of rows of air nozzles extending on both sides of the row of gas nozzles parallel thereto.
  • the air nozzles have a respective separate common air supply.
  • the air nozzles and gas nozzles have intersecting directions of discharge for mixing the gas and air.
  • the rows of air nozzles are symmetrically distributed with respect to the row of gas nozzles and are arranged so that the number of air nozzles in each row decreases from row to row in correspondence with increase of distance from the row of gas nozzles.
  • the air nozzles in symmetrical rows on opposite sides of the row of gas nozzles have uniform cross-sectional discharge areas and these increase from row to row in correspondence with increase in distance from the row of gas nozzles.
  • the arrangement of the gas nozzles and air nozzles can be such as to provide a plurality of individual pyramids.
  • the invention relates to a gas burner having separate gas and air supplies, more particularly, separate gas and waste air supplies, for the combustion of impurities contained in the waste air, consisting of atleast one group of nozzles, where, for mixing the gas with the air or waste air,the gasand air discharge directions of the nozzles of the same group, are intersecting.
  • the invention is based on the objective of creating a compact burner for the impurities contained in the waste air, which assures economical and complete burning of the impurities even when the waste air is supplied in irregular quantities and at varying pressures and temperatures, and which for the purpose of safe ignition and flame monitoring, should burn with a coherent flame.
  • each group with a number of successively arranged gas nozzles, and a number of rows of air nozzles on either side, running parallel to the row of gas nozzles, pressurized with a uniform pressure, and symmetrically distributed relative to the gas nozzles, where the number of air nozzles per row decreases from row to row with a corresponding increase of the distance from the gas nozzle row, and the discharge crosssection of the air nozzles and the distance of these from the plane of symmetry increase, and by the fact that the confronting air nozzles, the discharge directions of which are directed at one another, have a uniform dis charge cross-section.
  • the burner needs no expensive control or regulating devices; it is sufficient for the gas supply to be adjusted to suit the temperature determined in the combustion chamber.
  • the graduatedsystem assures optimum utilization of the burner chamber.
  • the gas burner can be made up of a number of groups of like base elements, which are successively arranged to form a series burner, or which intersect to form a flat burner. In both designs, only a single ignition device and a single flame monitoring device are necessary for safe monitoring, due to the formation of a coherent flame.
  • individual tunnel-like deflector plates are preferably arranged at intervals, against the outer sides of which, the flow from the air nozzles of the lowermost rows is directed.
  • FIG. 1 shows a gas burner formed as a flat, compact burner, in plan
  • FIG. 2 shows an enlarged portion in plan view, of the gas burner of FIG. 1,
  • FIG. 3 shows the gas burner in FIG. 1 in cross-section along line II and
  • FIG. 4 shows a portion of FIG. 3 on, enlarged scale.
  • the gas burner shown in FIG. 1 consists of a number of groups of successively arranged and intersecting nozzle groups. Each nozzle group has a number of successively arranged gas nozzles l and on either side of the gas nozzle row, parallel rows of air nozzles 2, 3, 4, 5, 6.
  • the gas nozzles 1 of all nozzle groups communicate via distribution pipes 7 with a central gas supply 8, whereas all air nozzles communicate via a common distributing mainfold 9 with a central air supply 10.
  • an impingement plate 11 is arranged, which deflects the gas jet discharged vertically from gas nozzle 1, to both sides, allowing it to emerge between the individual impingement plates 11 and mix with the air which is discharged from air nozzles 2 of the lowermost row, and similarly deflected by impingement plates 11.
  • Air nozzles 2, 3, 4, 5, 6 are disposed symmetrically relative to the gas nozzles l on both sides, in the form of steps, so that the spacing of the air nozzles of the same row opposite the respective gas nozzle row, increases with increasing distance from the gas nozzle row. As the distance from the gas nozzle row increases, the number of air nozzles decreases progressively from row to row, while the cross-section of the individual air nozzles increases from row to row.
  • Each air nozzle of a certain row on the one side of the gas nozzle row is arranged relative to an air nozzle of the appropriate row on the other side of the gas nozzle row, such that their jet always intersect in the plane of symmetry of the nozzle groups, as shown in FIGS. 3 and 4.
  • an ignition burner 12 For ignition of the gas burner as near as possible to the center of the burner, an ignition burner 12 is provided, which because of the special nature of the burner, is capable of igniting the complete burner.
  • a flame monitoring device 13 is arranged eccentrically as far as possible, so that for the safest possible flame monitoring, the position of the burner can be watched, at which there is the highest risk, due to a large distance between the ignition burner and the flame monitor, of the flame not being propagated fully as a result of gas deficiency.
  • the distribution of the gas nozzles and the air nozzles according to the invention in the case of a flat burner, produces a shape of nozzle floor made up of many individual pyramids.
  • the distribution of the gas nozzles and the air nozzles in accordance with the invention assures optimum burning of the impurities present in the waste air together with optimum utilization of space, regardless of the proportions of the available gas and air volumes relative to one another. Without the necessity for special regulating devices for the waste air, the proportion of air required for combustion of the gas is taken from the waste air, and burned together with the impurities contained therein, while the impurities in the re-. maining waste air, after mixing with the flue gases, are burned.
  • the burner in accordance with the invention is suitable for use as a proportional burner for large surfaces, as a result of the good mixing of gas and air.
  • a gas burner comprising a row of a plurality of gas nozzles, gas supply means coupled to said nozzles, a plurality of rows of air nozzles extending on both sides of said row of gas nozzles parallel thereto, said air nozzles and gas nozzles having respective discharge axes which lie in intersecting planes and air supply means coupled to said air nozzles for supplying the same with air at a uniform pressure, said rows of air nozzles being symmetrically distributed with respect to said row of gas nozzles and arranged so that the number of air nozzles in each row decreases from row to row in correspondence with increase of distance from the row of gas nozzles, the air nozzles in symmetrical rows on opposite sides of the row of gas nozzles being in confronting relation and having intersecting directions of discharges and uniform cross-sectional discharge areas,
  • a gas burner as claimed in claim 1 comprising a plurality of spaced tunnel-like deflector plates each individually disposed above a respective gas nozzle and having outer surfaces facing the innermost row of air nozzles whose discharge air is directed thereagainst.
  • a gas burner as claimed in claim 2 wherein the directions of discharge of symmetrical rows on opposite sides of the row of gas nozzles intersect in the plane of symmetry through said row of gas nozzles.
  • a gas burner as claimed in claim 2 wherein said rows of air nozzles are arranged in steps on opposite sides of said row of gas nozzles.
  • a gas burner as claimed in claim 4 wherein said steps successively increase in correspondence with the distance from the row of gas nozzles.
  • a gas burner as claimed in claim 2 wherein a plurality of rows of said gas nozzles are provided and are associated with rows of said air nozzles to form a plurality of individual pyramids.
