Definitions

  • the present invention relates to a coating and a method of lining a wall of a thermal apparatus, and than a brick and a corresponding anchor.
  • the device concerned such as an oven, a boiler or a combustion chamber (FR 2 495 284 A).
  • Such incineration boilers are provided for recover, through the fluid circulating in the tubes, the heat of combustion of household refuse and waste in order to develop this energy, either in the form of water hot for the heating of collective buildings, that is, with the addition of a turboalternator, to make current electric.
  • European patent EP-B2-080444 discloses an oven for sheet metal liner having a cast, fixed refractory liner by steel anchors which are drowned in prefabricated anchoring elements of refractory ceramic. These anchoring elements are molded in a refractory mass monolithic and are attached to the oven wall by bolts through. This technique makes it easy to replace old coatings for maintenance. However, it presents the disadvantage of having a restricted field of application, and in particular to be inappropriate for the coating of panels tubular.
  • the present invention relates to a lining of lining a wall of a thermal device that can allow mounting and easy and quick disassembly, including on panels tubular.
  • the lining coating of the invention can thus constituting a continuous protection package for test tubes tubular panels, allowing easy replacement of plates covering the panels.
  • the invention also relates to a method of packing of a wall of a thermal apparatus, which makes it possible to obtain a coating having the above qualities.
  • the process of the invention may allow for one-off execution and continuous way the protection of a wall of a thermal apparatus, including a wall of tubular panels. This process can enable fast and easy execution.
  • the invention also relates to a refractory brick and a refractory anchorage specifically adapted to the coating and filling method of the invention.
  • the wall of the thermal apparatus may be constituted by any surface, such as for example a flat, left surface, or constituted by the surface of a tubular bundle formed of a alternation of tubes and fins connecting the tubes.
  • the coating of packing is preferentially interposed between a source of heat, such as an incineration furnace, and the wall.
  • “Monolithic” mass means a mass placed in situ on the wall and not preformed. This installation can be done by casting, projection or tamping.
  • Refractory bricks have the peculiarity of being maintained on the wall by the masses themselves after curing. Thus, they do not require any means of attachment to Wall. Their function is to delimit several masses refractory, each of these masses being fixed by one or several anchors.
  • the lining of the invention is thus specified in view of the state of the art by the combined use of three types of elements: anchors, bricks and masses monolithic.
  • the coating of the invention introduces the presence of bricks refractory, which can marry the forms of the wall, such as tube shapes, and exert the function of separating refractory masses, while the anchors exert the function fixing these masses.
  • the wall being a surface of a beam tubular formed of an alternation of tubes and fins connecting the tubes, each of the bricks overlaps at least partially with least one of the tubes by marrying the shape of this tube.
  • This realization allows in particular to have a very weak game between bricks and the tubular bundle, which allows a watertight system for gases and chemical corrosion.
  • Each anchor is then advantageously attached to one of the fins. The assembly is thus facilitated.
  • the coating is advantageously constituted by coating, each of the panels being covered by at least one of the plates. It is interesting that each of the panels tubular is covered by a succession of contiguous plates. Preferably, these plates are identical and are offset from one panel to the adjacent panel.
  • At least two of the bricks have respectively two complementary lateral surfaces, arranged side by side on the wall and thus forming an area buffer between two disjoint parts of the coating.
  • An area free is usefully provided between these two bricks to allow a superficial dilation between the parts of the coating corresponding.
  • the coating preferably comprises seals soft placed on bricks, between bricks and masses adjacent refractories.
  • Such joints compensate for expansion monolithic masses. They are advantageously pre-glued and elastic at high temperature, and have a thickness that is function of the quality of the refractory masses adjacent to these joints.
  • Bricks preferentially have a cross section which decreases overall while moving away from the wall.
  • the decrease is understood in a broad sense, the cross-section may remain constant in one or more parts of the brick. Otherwise, the area bounded by the outline of the cross section of the bricks, although some parts of the brick are hollow due to wall protuberances due to example to tubes.
  • lower parts of the brick can be truncated, at such protuberances of the wall, the overall decay property of the section transversal remaining despite everything checked.
  • the coating comprises a coating refractory low mechanical strength applied to the surface of wall and anchorages, at least in areas of contact with refractory masses.
  • This coating allows a better disassembly of the upholstery in case of repair.
  • the coating has identical thermal properties to those monolithic refractory masses.
  • the lining is obtained by the pouring refractory masses into a formwork that includes an upper surface.
  • This upper surface of the formwork defines an outer surface of the coating, opposite the wall.
  • the formwork which serves as a mold for the refractory masses, allows also to maintain the bricks on the wall by pressure and is removed after hardening of the refractory masses. It allows to form the surface of the coating in a smooth and solid form.
  • the formwork allows the realization of vaults. he also allows to obtain an outer surface of the coating which follows the profile of the wall. In this case, the formwork is preferentially made of flexible materials. The formwork makes also possible the introduction of curvatures in the surface exterior of the coating, with respect to the wall.
  • At least one anchor serves as a support removable formwork for pouring masses on the wall.
  • These anchors have a dual function: to hook the masses refractory and temporarily fix the upper surface of the formwork.
  • At least one of these anchorages then preferably has a cross section that grows globally from the wall up to an outer surface of the anchor, the coating comprising means for removably fixing the formwork to the anchor, which cross or border this outer surface.
  • Cross section of the anchorage means the area bounded by the outline of the cross section of the anchor. The growth is here understood in a broad sense, the cross section can be constant in one or more parts of the anchor.
  • Fixing means "passing through the outer surface of anchoring” are means based on a penetration of the anchoring, such as for example a tapped hole which cooperates with a screw.
  • Fixing means "bordering the outer surface of “anchorage” are means attached to the side walls of anchoring.
  • the anchors In a particular embodiment involving anchorages having the double function of fixing the masses refractory and formwork, the anchors have different lengths depending on their position on the wall and the refractory masses have a variable thickness corresponding to the lengths of anchors.
  • This embodiment corresponds to the use of a flexible formwork whose upper surface follows contours wanted, which do not follow the contours of the wall.
  • this coating comprises fastening means to the wall of rods passing through the masses refractory and allowing a removable attachment of a formwork for the casting of these masses on the wall.
  • the coating comprises at least one removable fastening part of at least one of the anchors, secured at the wall.
  • the anchors can be very easily installed for the manufacture of the coating, or removed during disassembly for maintenance.
  • the anchors are preferably made of steel and / or refractory ceramic.
  • Such anchors provide a compromise between steel and ceramics. Indeed, the steel anchors have for disadvantage of deteriorating over time, especially under the effect of substances from the calcination of waste, but allow a good fixation to the wall.
  • the steel part is present for fixing to the wall, but it can be low enough compared to the surface exterior of the cladding to be protected and thus offer a better behavior in time.
  • the steel part penetrates inside the ceramic part.
  • the ceramic part comprises notches into which are inserted ends of the metal part.
  • the masses refractories are made of refractory concrete.
