Definitions

  • the invention relates to a gasburner comprising a gas nozzle, a gas-air mixing tube adjacent thereto and a burner housing, in which in the top of said housing a pattern of transverse burner slots and burner apertures, positioned alternatingly therewith and having different dimensions from the slots, has been provided, said pattern repeating itself in the transverse direction of the burner, round apertures exclusively having been provided at both transverse ends of the pattern, the slots and apertures extending in rows in the longitudinal direction of the burner.
  • the invention aims at improving said supply of propely air to the slots and thereby to further the burning process still more.
  • the burner apertures are positioned in identical longitudinal rows of slots with each time between two successive slots one or more differently shaped apertures, which together have a smaller crosssection than one of said slots and wherein longitudinal rows which are adjacent in the transverse direction show a phase shift such that in the transverse direction of the burner no slots of adjacent longitudinal rows are directly adjacent to each other.
  • a possibility to grant the apertures situated between the slots a smaller cross-section than the slots is present in an embodiment in which the burner apertures having the different dimensions are round apertures.
  • burner apertures having the different dimensions in the shape of shorter slots having a length which is substantially equal to 2/3 of the length of the first mentioned slots, the centre of each aperture being aligned,in the longitudinal direction of the burner, with that of the first mentioned slots.
  • the pitch or center-to-center spacing between successive transverse rows is in the range of 1.2 to 1.5 millimeters. Thereby concentrated generation of flames is obtained.
  • a predetermined pattern of burner apertures is provided, figure 1 only showing the pattern 4 at the beginning and at the end of the housing. Said pattern may be repeated at fixed spacing in the longitudinal direction of the housing 1, as also appears from figures 3 and 4.
  • Figure 3 shows a first possibility of the embodiment of the apertures pattern.
  • Each longitudinal row comprises rectangular slots 6 which are regularly alternated within this case three round apertures 7, the total crosssection of the apertures being smaller than that of a slot 6.
  • the rows 5 have mutually a phase shift such that adjacent to each slot 6 there are apertures 7.
  • the pitch or centre to centre spacing between a row of apertures 7 and a slot 6 in each longitudinal row is constant and also the pitch between the round apertures 7 in the transverse direction of the burner is constant through all of the burner pattern.
  • the pattern is such that in the longitudinal direction as well as in the transverse direction never two slots are directly successive to each other, but between two slots a plurality of the smaller apertures 7 are provided.
  • the startery air may penetrate more easily to all slots while, due to the apertures, yet a so called auxiliary gas structure is present between the slots whereby the burning process is maintained in uniform manner and a stable burning process is achieved.
  • each pattern exclusively LOws of apertures 7 have been provided so that the secondary air may easily flow towards the apertures from the portion of the burner tube outside the gas emitting portion and also there auxiliary gas is provided.
  • Each time between the burner apertures pattern in the longitudinal direction of the burner a portion of the burner is present having no apertures whatsoever in order that also from that side the secondary air can easily penetrate to the burner apertures.
  • Figure 4 shows a different burner pattern according to the invention.
  • the difference with figure 3 is only that each three apertures 7 between the slots 6 have been replaced by shorter slots 7, having a length which is substantially equal to 2/3 of the length of a slot 6 and the centre of which is in the longitudinal burner direction aligned with that of the slots 6. Also thereby the secondary air can more easily reach all slots 6.
  • the number of apertures in the transverse direction of the burner may be varied and depends on the heat capacity-for which the burner is designed. Per pattern usually a longitudinal row has three to ten successive slots or aperture series respectively.
  • the burner is suitable for the gas families of natural gas, city gas and liquified gas.
