Definitions

  • the present invention relates to a wafer with a honeycombed radiant face for a radiant burner.
  • plates for radiant burners have rows of holes passing through them and serving to channel the fuel-oxidant mixture from the rear face of the plate to the radiating face.
  • holes passing through them and serving to channel the fuel-oxidant mixture from the rear face of the plate to the radiating face.
  • the cells formed leave a number of holes between them which do not participate in the increase in the radiating power of the wafer.
  • the object of the invention is to remedy the abovementioned drawbacks, and others, of known embodiments using a wafer with a dimpled front face for a radiant burner, formed of a ceramic material, comprising rows of holes for passage of oxidant-fuel mixture and in which it is possible to provide cells, regularly distributed in rows and involving all the holes existing in the plate, whatever the pattern of hardware, squaring or shifting of the rows of holes
  • a maximum heat transfer is thus obtained between the flames and the wafer by increasing the contact surface with the material of the wafer, all the combustion products sweeping the walls of the cells.
  • the cells to be provided in the wafer are defined by their theoretical base, that is to say their geometric base, and their depth profile.
  • the actual shape of the cells is then determined from the theoretical profile, taking into account the conditions of implementation, such as the technological conditions of machining, molding and other shaping.
  • FIGS. 2 to 7 several patterns of cell distribution have been shown which can be obtained as a function of the patterns of holes and rows in the wafer.
  • fig. 2 we are dealing with a distribution of holes corresponding to equilateral quinconcing and we obtain, in this case, hexa-shaped cells gone regular.
  • AV 1 to AV 7 we are dealing with a distribution of holes corresponding to equilateral quinconcing and we obtain, in this case, hexa-shaped cells gone regular.
  • AV 1 to AV 7 we are dealing with a distribution of holes corresponding to equilateral quinconcing and we obtain, in this case, hexa-shaped cells gone regular.
  • AV 1 to AV 7 we are dealing with a distribution of holes corresponding to equilateral quinconcing and we obtain, in this case, hexa-shaped cells gone regular.
  • AV 1 to AV 7 we are dealing with a distribution of holes corresponding to equilateral quinconcing and we obtain, in this
  • Fig. 4 shows the patterns obtained with a distribution of holes corresponding to a grid, the theoretical base of the cell having the shape of a square.
  • Fig. 5 shows, for the same grid distribution of the holes, patterns of distribution of cells obtained by choosing for the theoretical cell base a form of hexagon, of flattened profile.
  • Figs. 6 and 7 show patterns of distribution of cells obtained in the event of any offset of the holes of the different rows.
  • the theoretical base of the cell is in the form of an irregular hexagon while, in FIG. 7, for the same distribution of holes, an irregular quadrilateral shape has been chosen as the theoretical base of the cell.
  • the inserts according to the invention are manufactured by pressure molding and it is obvious that the distribution and the shape of the cells have an influence on the manufacturing process since they condition the production of the corresponding parts of the mold, which must have the efficiency and optimal reliability while being as low a cost price as possible.
  • FIGS. 8 and 9 corresponding to a distribution of the holes with equilateral quinconcing, we adopted for the real base of the alveolus a regular hexagon shape, the pattern of fig. 8 being obtained by the plot involving the right vector and the pattern in fig. 9 being obtained by the plot involving the vector on the left.
  • FIGS. 8 and 9 A comparison of FIGS. 8 and 9 with FIG. 2, which gives the distribution patterns of the theoretical bases of cells in the same case, shows that the real hexagons have been slightly turned around their centers compared to the theoretical hexagons, this angular offset being justified by machining considerations.
  • the cells have a depth profile which is highlighted in FIGS. 10 and 11, FIG.
  • FIG. 10 being a cross section taken along line-XX of la.fig. 8 while fig. 11 is a cross section taken along the line YY of FIG. 9.
  • Each cell is thus delimited, from the base in the shape of a regular hexagon, by curved facets starting from the sides of the hexagon and ending at a bottom defined by a plane located at a distance H from the front face of plate, the intersections of the facets with said bottom plane defining small hexagons, visible in figs.8 and 9 and respectively circumscribed to the central holes of the cells, visible in T1, in figs. 8.9, 10, 11.
  • FIGS. 12A to 12E a few examples of depth profiles have been indicated which it is possible to adopt for the cells, in particular a hemispherical profile, a truncated conical profile, a stepped cylindrical profile and a simple cylindrical profile. It is possible to envisage other profiles, for example profiles of surfaces of revolution such as parabolic or composite profiles such as cylindrical.
  • the angle at the top of the bottom of the cell, starting from the center of the central hole of said cell is between approximately 30 and 180 °.
  • the depth of the cells should preferably be between 0.5 mm and 3/5 of the thickness of the insert.
  • the orifices provided in the wafer are preferably cylindrical and have a diameter of between approximately 0.4 and 5 mm.
  • the equivalent diameter of the theoretical cell base is defined by the sum of the diameters of two neighboring holes and the thickness of material between these two holes.
  • the holes may not be located, as in most of the preceding illustrative examples, around the periphery of the cell, and in particular at the vertices of the perimeter thereof, but the holes may also be arranged inside the socket.
