Definitions

  • the present invention relates to a burner with a diffuser resistant to high operating temperatures, in particular to a premix burner.
  • EP 0679839 discloses a gas burner consisting of a distribution chamber designed to receive air and a combustible gas and partially delimited by a thin perforated panel which acts as the burner bar.
  • the panel is supported by a plate surrounding the distribution chamber.
  • the distribution chamber has a series of apertures linked to gas feed ducts in the form of Venturi tubes with inner surfaces able to trap thermal radiation.
  • the high thermal stresses can easily causes deformation and mechanical stresses on the diffuser of the burner, which may cause the diffuser to break.
  • This drawback occurs with any form of diffuser of the burner, but has been shown to be particularly serious in burners with flat diffusers.
  • special materials for making the diffuser of the burner for example a metal mesh or a ceramic material.
  • Burners of this type are known from patent applications M02003A000180 and MO2004A000031 , in the name of the same applicant.
  • burners wherein the diffuser of the burner is divided into a plurality of diffuser elements that are adjacent to one another, that are free to expand in at least one direction.
  • the present invention aims at providing burners of the aforementioned type with divided diffusers that are simpler and cheaper to make.
  • a burner is provided that is suppliable with a mixture of air and fuel, comprising a burner body provided with a diffuser on which openings are made for the passage and subsequent combustion of said mixture, said diffuser being divided into a plurality of diffuser elements that are adjacent to one another, said diffuser elements being fixed to a support and distribution element provided with first mechanical coupling means for coupling with said diffuser elements and with openings for distributing said mixture to said diffuser elements characterised in that said first coupling means comprises further openings made in said support and distribution element.
  • the construction and assembly of the burner is significantly simplified, inasmuch as a same element acts as a support for the diffuser elements and as a distributor of the mixture to the diffuser elements and it is therefore no longer necessary to provide a distributing element for each diffuser element. Furthermore, fixing the diffuser elements to said support and distribution element is very simple and rapid to achieve, thus reducing considerably burner assembly time.
  • the diffuser elements 2 are fitted next to one another on a support and distribution element 11, that may have the form of a flat quadrangular plate, as shown in Figures 1 and 2 , but may also have a polygonal, circular oval shape and have a convex surface.
  • a support and distribution element 11 may have the form of a flat quadrangular plate, as shown in Figures 1 and 2 , but may also have a polygonal, circular oval shape and have a convex surface.
  • slits 12 are made that are arranged in rows that are substantially parallel to one another and are intended to be coupled with the appendages 10 of the diffuser elements 2 to fix the elements in position.
  • the plate 11 is furthermore provided with groups of rows of holes 13, each group being arranged between two rows of slits 12, in such a way as to be level with a diffuser element 2 when the diffuser elements 2 are fitted to the plate 11.
  • the groups of rows of holes 13 distribute the mixture of air and fuel delivered to the burner to the openings 7, 8, 9 of each diffuser element 2, guaranteeing a distribution of the flow of mixture to the aforementioned openings.
  • the rows of slits 12 and the rows of holes 13 can be arranged parallel to a pair of opposite sides of the plate 11 or tilted in relation to the sides of the plate 11.
  • the plate 11 performs both the function of support to the diffuser elements 2 and the function of distributor of the flow of mixture, which makes the burner structure more compact and makes assembly thereof very simple, it no longer being necessary to provide a separate distributor element for each diffuser element.
  • the plate 11, with the diffuser elements 2 that are fixed to it, constituting the diffuser 1 of the burner, can be fixed to a support frame, with a shape corresponding to the shape of the plate 11, which will be disclosed below.
  • the diffuser elements 2 can be made of metal, ceramic material or of any other material resistant to the operating temperatures of the burner.
  • the upper face 3 of the diffuser elements 2, rather than being provided with the openings 7, 8, 9, can be made of porous material with pore dimensions sufficient to ensure the passage of the mixture of air and fuel without excessive load losses.
  • FIGS 7, 8 and 9 show a second embodiment of a burner according to the invention, in which the diffuser elements 2 are fixed to a support and distribution element 14 with a prismatic shape, which similarly to the plate 11 disclosed previously, also performs the function of distributor of the mixture of air and fuel delivered to the burner.
  • Each face of the support and distribution element 14 is provided with two parallel rows of slits 12, intended to be coupled with the appendages of a diffuser element 2, to fix in position the diffuser element 2 on the respective face of the support element 14. Between the two rows of slits 13 parallel rows of holes 13 are arranged, to distribute the mixture to the openings made on the upper face of the diffuser element 2.
  • the burner is completed by an upper base and by a lower base that are not shown, in one of which a hole is made for connecting a pipe supplying the mixture of air and fuel.
  • the support and distribution element 14 may as an alternative have a cylindrical shape, in which the diffuser elements 2 will preferably have a slightly arched shape, in such a way as to define as a whole a diffuser 1 with a substantially cylindrical shape.
  • a support and distribution element 14a- that has an upper face 15 in which a plurality of rows of slits 12 is made for fixing diffuser elements 2; between pairs of rows of adjacent slits 12 rows of holes 13 are made for distributing to the respective diffuser element 2 the mixture of air and fuel supplied to the burner. Both the rows of slits 12 and the rows of holes 13 are arranged parallel to a pair of opposite sides of said upper face 15.
  • the support and distribution element 14a furthermore has two L-shaped side faces 16, 17 connected to a pair of opposite sides of the upper face 15, to constitute two support feet for the support and distribution element, suitable for example for facilitating the coupling with a support frame and/or adjusting the height of the diffuser of the burner inside a combustion chamber, by varying for example the height H of the side faces 16, 17.
  • the rows of slits 12 and the rows of holes 13 are arranged perpendicular to the pair of sides to which the side faces 16 and 17 are connected.
  • FIGs 12 to 14 another version of a support and distribution element 14b according to the invention is shown, which differs from the support and distribution element 14a inasmuch as the rows of slits 12 and the rows of holes 13 are parallel to the pair of sides to which the side faces 16 and 17 are connected.
  • a burner according to the invention can be made with a support and distribution element 14a, 14b, with the respective diffuser elements 2 fixed thereto ( Figures 11 and 14, 15 ), all fitted in a support frame.
  • a burner according to the invention can be made with a plurality of support and distribution elements 14a, 14b that are placed near one another and fitted in a containing frame, with the respective diffuser elements 2 fixed to each support and distribution element 14a, 14b.
  • FIG. 16 and 17 a still further version of a support and distribution element 14c is shown that differs from the support and distribution elements 14a and 14b by the fact that it has a box structure with an L-shaped side face 16, 17, 18, 19 connected to each of the sides of the upper face 15; rows of slits 12 and holes 13 are arranged parallel to a pair of opposite sides of the upper face 15 of the support and distribution element 14c.
  • the rows of slits 12 and the rows of holes 13 made in the upper face 15 of the support and distribution elements 14a, 14b, 14c can also be arranged tilted in relation to the sides of said upper face 15.
  • the upper face 15 of the support and distribution elements 14a, 14b, 14c, similarly to the plate 11, may be flat and quadrangular in shape, but also have a polygonal, circular, oval shape and have a convex surface.
  • Figures 18 to 23 show an embodiment of a support and containing frame 21, with which the support and distribution elements 11, 14a, 14b, 14c can be coupled, with the relative diffuser elements 2, to assemble a burner according to the invention.
  • the frame 21 is a composable frame 21, consisting of two pairs of frame elements 22, 22a; 23, 23a that are assemblable together.
  • Each element 22, 22a of the first pair of frame elements consists of a substantially rectangular flat element 24 a longitudinal edge 25 of which is folded back into a squashed "S" shape, with an upper part 25a having a height a and a lower part 25b having a height b ⁇ a.

  • the height c of the upper part 27a of the longitudinal edge 27 is less than the height a of the upper part 25a of the longitudinal edge 25 and the height d of the lower part 27b of the longitudinal edge 27 is greater than the height b of the lower part 25b of the longitudinal edge 25.
  • the frame elements 22, 22a, 23, 23a are coupled together to form a quadrangular frame, as shown in Figure 18 , by inserting the upper part 27a of each edge 27 of the frame elements 23, 23a inside the upper part 25a of each edge 25 of a corresponding frame element 22, 22a, whereas the lower part 25b of each edge 25 of the frame elements 22, 22a is inserted into the lower part 27b of a corresponding frame element 23, 23a, all as shown in Figure 19 .
  • the fixing of the frame elements 22, 22a, 23, 23a can be achieved by crushing the elements after they have been coupled together and can be reinforced by welding.
  • Figures 24 to 29 illustrate the assembly of a support and distribution plate according to the invention, for example a plate of the type shown in Figures 1 and 2 .
  • the plate 11 shown in Figures 24 to 29 has a slightly convex shape, but the same assembly can be achieved with a flat plate 11, or with a plate 14a, 14b, 14c.
  • Figures 30 to 33 show another diffuser version 28, associable with a frame 21 like the one shown in Figure 18 and/or a support and distribution plate 11, 14a, 14b, 14c.
  • the diffuser 28 consists of a plurality of diffuser elements 29 arranged parallel to one another and connected together along the longer sides by elastic-hinge connecting means 30.
  • the elastic-hinge connecting means 30 are used to absorb the heat expansion generated by the temperature variations to which the diffuser 28 is subjected during burner operation, thus enabling a reduction of the mechanical stresses due to said heat expansion and an increase in the working life of the diffuser 28.
  • the diffuser 28 may be provided with appendages similar to the appendages 10 of the previously disclosed diffuser elements 2 for coupling with a support and distribution plate 11, 14a, 14b, 14c.
