Definitions

  • the present invention relates to a central heating device, comprising a boiler and an oil burner with, disposed between the burner and the walls of the boiler, a removable flame-permeable structure, composed of juxtaposed elements including at least one perforated sheet and linked by means of attachment to a support whose base rests on the floor of the hearth, a structure intended to be brought to the incandescence to improve combustion and thereby reduce the smoke and soot deposits in the hearth.
  • the invention as characterized in the claims solves the problem posed by the fact that the edges of each perforation of said perforated sheet are provided with prominent burrs directed towards the flame.
  • the invention also solves the problem posed by the production of said perforations by indicating a method for obtaining them.
  • the advantages obtained thanks to this invention consist essentially in the surprising effect that the prominent burrs of said structure constitute hot spots which, upon ignition, become incandescent and contribute to good combustion while remaining effective even at a very reduced flame regime.
  • the prominent burr surrounding the holes also has the effect of producing strong turbulence which contributes to complete combustion of the fuel oil.
  • the structure is placed in the hearth of the boiler after the refractory bricks have been removed. If necessary, bricks can be left on the boiler floor to complete the height and center the structure in relation to the flame.
  • This structure makes it possible to transform the normal flame of the burner into a bluish flame, much hotter which crosses a permanent fiery brazier before reaching the boiler containing the circulating water. This very hot flame eliminates the causes of pollution, because it completely burns all the components of the fuel oil and prevents fouling of the boiler, the burner and the chimney, even if the fuel oil is of secondary quality.
  • the removable structure 3 consists of a rectangular base frame 4 of profiled iron folded in the four corners and welded. On this frame is welded a median cross 5, and on this cross 5 is welded an amount 6 consisting of a bar folded in hairpin 7. In the lower part of this amount is interposed a vertical bar 8 of spacing, welded on the two upright bars and on the cross member, and reinforced by a sheet 19 welded with edge.
  • the upright thus constitutes a slide on which the active part of the structure is fixed at an adjustable height.
  • the welds of the upright 6, 8 and of the cross-member 5 are protected by a screen 20 which is a sheet metal folded into the shape of a roof and welded to the frame 4.
  • the active part of the structure comprises, from the face intended to be turned towards the flame of the burner 1, cross-pieces 14 made of sheet metal folded in the shape of a pyramid and clamped on a plate 13 with the interposition of a tube 16. Then, there is a finned crown 18. Rings 15 maintain the spacing.
  • a large perforated plate 11, 12 is placed which rests on the sliding upright 6, the whole being mounted on a central bolt 17 and tightened by a nut 9 and by means of a plate 10.
  • the perforations of the sheet 11, 12 constitute an essential character of the invention.
  • the material of the holes 21 is not removed but repelled in the form of prominent burrs 22 directed towards the flame. They are obtained very easily by means of pyramidal punches with square section and a matrix with round holes.
  • the perforated sheet 11 can be either flat or folded at its upper part 12 as illustrated, or also folded at the sides.
  • All the elements of the structure are made of sheet steel special refractory to high temperatures.
