Definitions

  • the invention relates to a radiant burner for boilers, consisting of a support plate with a gas supply line leading to a gas inflow opening in the support plate and with a curved burner surface made of wire mesh arranged on the other side of the support plate.
  • Radiation burners of this type are known, for example, from US Pat. No. 3,360,028.
  • the curved burner surface made of wire mesh has an elongated, approximately semi-cylindrical shape, which means that the circular gas inflow opening in relation to the burner surface inevitably becomes very small, resulting in poor gas distribution, on which even a small slotted diaphragm behind the gas inflow opening does not change anything significantly.
  • such a burner is poorly suited for today's compact spatial shapes of combustion chambers or boilers, i.e. one would have to arrange several such semi-cylindrical burners in parallel in order to be able to approximately achieve a largely uniform radiation exposure of the combustion chamber walls involved. The same applies approximately to a burner according to US Pat. No. 3,291,187.
  • a likewise poor gas distribution is also shown by a radiation burner according to FR-A-1 361 509, which practically has a spherical shape and also has a small gas inflow opening in relation to the size of the burner surface.
  • the spherical shape results in considerable reflections on the burner connection side.
  • the object of the invention is to improve it in such a way that the largest possible gas inflow opening is available with respect to the size of the burner surface, the shape of the burner surface is as stable as possible and the gas distribution is as uniform as possible between the inflow opening and the burner surface should be accessible on the entire burner surface.
  • a steel burner of the generic type according to the invention in that the burner surface is designed in the form of a hemisphere and concentrically below it and with a distance that is substantially smaller with respect to the hemisphere diameter of the burner surface, at least one gas distributor which is also hemispherical and also fastened to the supporting plate Perforated sheet is arranged, and that the diameter of the gas inflow opening corresponds essentially to the diameter of the hemispherical gas distributor.
  • the radiant burner consists basically and in a known manner of a support plate 1 with a gas supply line 3 leading to a gas inflow opening 2 in the support plate 1 and with a curved burner surface 4 made of wire mesh arranged on the other side of the support plate 1.
  • the burner surface 4 is designed in the form of a hemisphere and concentric with this and with a distance A which is substantially smaller in relation to the hemisphere diameter D of the burner surface 4, at least one gas distributor 5 which is also hemispherical and also fastened to the support plate 1 Perforated sheet is arranged, and that the diameter D1 of the gas inflow opening 6 corresponds essentially to the diameter D2 of the hemispherical gas distributor 5 (see Fig.4).
  • the support plate 1 is provided with annular step embossments 7, to which the burner surface 4 and the at least one gas distributor 5 are connected with their peripheral edges 8.
  • the peripheral edge 8 of the burner surface 4 is simply attached to the support plate 1 by folding over the edge of the support plate.
  • the support plate 1 is in relation to the gas supply side GS in the form of formed on the burner axis 9 convexly curved gas guide funnel 10, which also forms a step embossing 7 at the outlet, which centers the inner gas distributor 5 '.
  • this gas distributor 5 ' has a flared small edge 7' which serves as a centering for the second gas distributor 5 (see also FIG. 3).
  • a displacement body 12 in the interior 11 of the hemispherical burner surface 4 and in front of the gas distributor 5 'in the funnel 10 and a gas inflow chamber 13 in the form of a in front of the opening 2 of the support plate 1 against the interior 11 open, spiral or helical extending and reducing in cross-section gas guide channel 14, as shown in FIGS. 1, 3, from which it can also be seen that the support plate 1 with the interposition of a heat insulation ring 15 with a support plate 16th connected and this is provided with the gas inflow chamber 13.
  • the carrier plate 16 forms the closing door for the combustion chamber 18 of a "compact boiler" 19, of which only the upper part of interest is shown in FIG. 6.
  • FIG. 3 A special embodiment with regard to the fastening of the gas distributors 5, 5 'is illustrated in FIG. 3.
  • the outer gas distributor 5 is attached to the support plate, which is relatively close to the actual, extends from the wire mesh formed burner surface 4 and is thus also exposed to relatively high and changing heat loads, which can lead to the attachment tearing.
  • Such cracks do not render the burner inoperative, but the gas distribution to the burner surface, which is as uniform as possible, is required by the gas distributors 5, 5 ' Such cracks or "leaky" areas are disturbed to a certain extent.
  • the burner is designed according to FIG. 3 such that when two gas distributors 5, 5 'are arranged, the width B of the peripheral edge 8 of the inner gas distributor 5' is essentially the radial distance A 1 of both gas distributors 5, 5 'plus the width B1 of the peripheral edge 8 'of the outer gas distributor 5 is attached to that of the inner one, the peripheral edge 8' being attached to that of the inner gas distributor 5 'near the attachment area AB of the inner gas distributor 5' on the support plate 1.
  • the outer gas distributor 5 is no longer in direct connection with the support plate 1, but is held by the peripheral edge of the inner gas distributor 5 ', which in turn is fastened to the support plate 1 as far as possible from the burner surface.
  • the range of motion of the peripheral edge of the outer distributor 5, or one near the burner surface is increased to a sufficient extent, and the peripheral gas distributor 5 can no longer be torn off at the peripheral edge.
  • the same effect would also be achievable if one arranged an additional carrier ring on the carrier, which would only be attached to the carrier on the inner circumference and on which one would attach the peripheral edges of the gas distributors.
  • a further insulation ring 20 is arranged under the support plate 1 in the region of its outer circumference between the latter and the heat insulation ring 15, this lying on the inside against the outer step embossment 7 of the support plate 1, and finally the support plate 1 with its outer peripheral edge fixed by an externally placed clamping and insulation ring 17 on the heat insulation ring 15.
  • This training also contributes directly to the heat relief of this area, as it results from the lower annular edge area of the burner surface 4 no more gas can escape and burn there.
  • Such a ring 17 could also easily be placed on the atmospheric burner according to FIG. 4, which of course is to be arranged in the horizontal position, as shown, in the lower region of a boiler burner shaft.
