Definitions

  • the present invention relates to a device for protecting a heat recovery boiler screen, in particular for refuse incineration ovens, this screen being formed of vertical tubes joined by welded securing fins, arranged in brick cavities. refractory, and provided with means for hanging refractory bricks. It also extends to a method of manufacturing this device.
  • each tube in addition to the junction fins, be provided with fins intended for hooking bricks, and in that it is supplied with bricks of two different types.
  • the object of the present invention is to provide a device for protecting boiler screens which does not require welding on each tube of fins for attaching bricks, and which only uses one type of refractory brick.
  • the device according to the invention is characterized in that the screen has windows pierced in the securing fins, in that the bricks are each provided with at least one pin latching pin forming an angle with the horizontal and such that each brick is kept suspended by its weight in the window (s) of the corresponding screen, and in that the gaps remaining between the bricks, their lugs and the screen are filled with refractory cement .
  • the windows of the screen are of substantially rectangular shape, as is the cross section of the nipples for hanging the bricks.
  • the manufacturing process according to the invention is characterized in that the longitudinal fins are welded between the vertical tubes, in that the windows are cut from these fins at regular vertical spacings, corresponding to the height of the refractory bricks , in that a layer of refractory cement is applied to the surface of the tubes and fins intended to receive the refractory bricks, and what is hung in the windows each of the bricks by its hooking stud.
  • the device comprises metal boxes filled with refractory cement, welded between the vertical tubes of the longitudinal fins, windows are cut from these fins with regular vertical spacings, corresponding to the height of the refractory bricks, applied to the rear face fins around the windows a housing, and welds this housing on this rear face, the housing is filled with refractory cement, a layer of refractory cement is applied to the surface of the tubes and fins intended to receive the refractory bricks, and we hang in the windows each of the bricks by its hooking stud.
  • the tubes 1 and 2 and the adjacent tubes are joined by fins such as 3, 4, 5, to form a screen.
  • the fin 3 arranged between the tubes 1 and 2 is pierced at regular vertical intervals with windows for hanging refractory bricks, for example with silicon carbide.
  • a single window 6 and the corresponding refractory brick 7 have been shown.
  • the refractory brick 7 is provided with a hooking stud 8 with an axis inclined on the horizontal, for example at 45 °, and directed downwards.
  • the window is of substantially rectangular shape and the cross section of the attachment stud is also rectangular, and of height and width slightly less than the height and the width of the window.
  • a refractory cement 9 is placed in the gaps remaining between the refractory bricks and between these and the metal screen, in particular in the window around the periphery of the attachment stud.
  • horizontal rods such as 10 and vertical rods such as 11 ensure good securing of the adjacent bricks vertically and horizontally.
  • the device of Figures 3 and 4 is similar to that of Figures 1 and 2, but it further comprises a metal box 12 welded to the junction fin by weld beads 13 above the window and 14 below the window.
  • This box has a rear panel 17, an upper panel 16 and a lower panel 18. It is applied laterally against the periphery of the tubes 1 and 2, and thus constitutes a cavity which is filled with refractory cement around the nipple d anchor 8 of the corresponding brick. It is possibly hung on the lower edge of the corresponding window by a flat blade forming a spring (not shown).
  • windows are formed at regular vertical intervals, corresponding to the height of the refractory bricks, windows by automatic punching.
  • a layer of refractory cement of a few centimeters on the surface of the fins and tubes, then hang the bricks in the windows thanks to their hooking stud, after having also fitted the side faces of the bricks facing each other a layer of refractory cement.
  • the connecting rods made of refractory material 10, 11 are introduced into the vertical and horizontal channels of the lateral, upper and lower faces of the bricks.
  • the protective device comprises a box filled with refractory cement drowning the nipple for hanging the brick (fig. 3 and 4)
  • the box 12 is placed behind the window, after having possibly hung it on the lower edge of the corresponding window thanks to a flat blade forming a spring.
  • the upper and lower sides of the box are welded to the fin with weld beads, the cavity thus formed is filled with refractory cement, then the layer of refractory cement is applied to the tubes and the fins.
  • the side faces of the bricks are also provided opposite with a layer of refractory cement, and the rods for fastening the adjacent bricks are introduced into the channels and verticals of the bricks.
