Definitions

  • the invention relates to a method for producing refractory walls for protecting ovens or combustion chambers as well as to a refractory brick used according to said method.
  • combustion chambers have on their walls tubular panels produced from welded tubes and fins which make it possible to circulate a heat transfer fluid inside the panels heated during combustion.
  • tubular panels said tubes were spaced from each other but not joined by fins, which allowed shaped refractory bricks to be introduced between the tubes to form the protective refractory wall.
  • This technique can no longer be used in the case of tube panels and welded fins because it is no longer possible to thread the bricks between two tubes due to the fins.
  • This type of embodiment decreases the very resistance of the refractory brick due to the through holes and, on the other hand, requires closing of each fixing hole after mounting.
  • the tubular panels consist of a bundle of independent tubes, spaced apart and arranged substantially parallel to one another.
  • the refractory wall is formed from a multitude of shaped refractory bricks, hung on the tubes by means of fixing lugs, integral with the tubes.
  • each tube are welded diametrically opposite tabs substantially in the plane of said tubular panel.
  • the bricks have a U-shaped profile in the branches of which open housings are provided corresponding to said fixing lugs.
  • Such an embodiment has many drawbacks; in particular, the production of such housings makes the bricks fragile, the welding of the legs on the tubes carrying the heat transfer fluid is delicate and risks reducing their resistance.
  • the object of the present invention is to propose a process for producing refractory walls for the protection of ovens or combustion chambers, which makes it possible to overcome these drawbacks and which, on the one hand, does not reduce the mechanical resistance of the bricks and d 'on the other hand, does not require any shutter after mounting.
  • Another object of the present invention is to provide a refractory brick for protecting tubular panels which has a shape adapted to the panels and has a smooth and full face on the boiler side while allowing it to be easily mounted on the panels.
  • Another object of the present invention is to provide a method for producing refractory panels for protecting ovens or combustion chambers using refractory bricks in shape, such that their fixing can be carried out in staggered rows in order to avoid the chimney effect by pointing the bricks.
  • Another object of the present invention is to provide a method for producing refractory protective walls using refractory bricks which have a real and effective seal.
  • Another object of the present invention is to provide a method of producing refractory protective walls from refractory bricks of intended shape such that the assembly is self-fixing and self-locking due to the configuration of the bricks.
  • the refractory brick of the present invention is characterized in that it has, on its inner face, at least two grooves adapted to said panel tubes, the center distance of which corresponds substantially to that of two adjacent tubes and that the said housing (s) are blind and provided in the area of the greatest thickness of the brick, so as not to reduce its resistance, and offset with respect to said grooves.
  • the present invention relates to the production of refractory walls for protecting ovens or combustion chambers generally constituted by a hearth inside which combustion is carried out and on the walls of which is provided a heat exchanger capable of capturing the heat energy released. to heat a heat transfer fluid for the return of heat in another device.
  • furnaces or combustion chambers are generally but not exclusively found in household incineration or industrial waste incineration boilers.
  • tubular panels (1) which themselves consist of tubes (2) capable of allowing a heat-transfer fluid to circulate and joined together by welded fins (3).
  • the bricks (5) are in the form of a volume adapted to the panel (1) defining an inner face (8) and an outer face (9).
  • the inner face (8) is adapted to match the shape of the tubular panel and the outer face (9) constitutes the face of the fireproof protective wall on the hearth side.
  • each brick (5) has on its inner face (8) at least one blind housing (6) having a longitudinal axis (10) disposed transversely and inclined relative to said face (8) at an angle designated by "at”.
  • this angle " ⁇ " will advantageously be between 45 and 90 ° and the longitudinal axis (10) will be directed upwards to allow the self-fixing of the brick (5) by gravity effect, as shown in Figure 2.
  • each refractory brick (5) will comprise two blind housings (6) and (11) whose longitudinal axes respectively (10) and (12) are arranged in the same axial plane substantially perpendicular to the inner face ( 8.) and are substantially parallel to each other.
  • the rotation of the latter will be avoided relative to its fixing (7).
  • the inner face (8) has two grooves (13) and (14) adapted to said tubes (2) of the panel (1) whose center distance corresponds substantially to that of the tubes.
  • the said housing (s) (6) and (11) are then provided in the region of the greatest thickness. brick (15), for example substantially at equal distance from each groove (13) and (14).
  • the blind housing (s) (6) and / or (11) are placed in the zone (15) of the greatest thickness of the brick so as not to reduce the mechanical resistance of the refractory brick and a substantially constant section is kept around said housings.
  • the blind housing (s) (6), (11) and the corresponding fixing lugs (7) are provided for hooking the bricks (5) in staggered rows in order to avoid the "chimney effect" by the brick joints, as shown in particular in Figure 3.
  • each brick (5) covers two adjacent tubes (2) while being fixed by the corresponding fixing lugs (7) placed on the intermediate fin (3) contiguous to these two tubes (2 ).
  • the embodiment of the brick (5) described above is entirely suitable for this staggered laying process.
  • each (5) is provided with two blind housings (6) and (11) substantially placed in the same vertical axis and welding lugs (7), of geometric shape corresponding to that of the blind housings, on the fins (3) of the tubular panels (1) according to the dimensions of each brick (5).
  • sealing is carried out between each brick (5) by placing between each lateral face (16) to (19 ) refractory bricks (5) a refractory seal (20).
  • each of the side faces (16) to (19) has a groove (21) capable of receiving this refractory seal (20).
  • the seal may be made according to techniques known to those skilled in the art, in refractory materials remaining elastic at high temperature.
