Definitions

  • the above described L-shaped hooks 18 and support arms 17 are supporting members which slidably engage in indent 19 in the foregoing refractory tiles 13.
  • This installation structure of the refractory tiles prevents the support members from becoming exposed to the combustion side of the tiles and prevents their corrosion by combustion gases to thereby also prevent the refractory tiles from falling off or becoming damaged.
  • the refractory tiles are not installed by sliding the indent on the refractory tiles along support members projecting from the water pipes, but rather, the refractory tiles are set directly upon the water pipes using an insertion type of engagement to facilitate the placement of refractory tiles in areas where the water pipes assume complex shapes such as bends or openings where the sliding installation is not possible, and since this structure does not require the use of fireproof sleeves, it is less costly and facilitates installation.
  • the foregoing support members and the refractory tiles are affixed together using an adhesive such as mortar, which in addition to the adhesive strength provided by the adhesive, firmly affixes the support members in place once the adhesive has dried and been fired.
  • an adhesive such as mortar, which in addition to the adhesive strength provided by the adhesive, firmly affixes the support members in place once the adhesive has dried and been fired.
  • the strength developed after drying and firing the adhesive that attaches the foregoing refractory tiles to the water pipes, and such installations can prevent the refractory tiles from falling off not only in the perpendicular direction, but even when they are installed on ceilings.
  • an opening of the indent on the refractory tiles is wider than the tip of the support member to allow the indent to be freely inserted in the fore-aft direction onto the support members, and the indent widens in the depth direction towards the bottom of the indent.
  • the surface area on the inside surface of the foregoing indent is greater than it would be for the case where the width between the walls was the same at the top and bottom of the indent, there is an increased contact surface area between the foregoing refractory tiles and the adhesive. Since the refractory tiles are pressed in place toward the water pipes with mortar or other adhesive disposed between the support members and the tiles, the surface area under the compression is increased to improve the holding effect between the mortar and said refractory tiles, to create a strong junction. As a result, a refractory tile structure firmly affixes the tiles and prevents them from falling off from not just the vertical walls, but the ceiling areas as well.
  • the mortar or other adhesive disposed between the foregoing refractory tiles and the water pipes can be extruded out through the holes, to enable visual confirmation that the spaces have been completely filled without air bubbles to thereby assure the sound installation and the filling of the voids between the refractory tiles and water pipes.
  • the present invention provides a fireproof structure in stoker type incinerators where the gas retention time is about 2 seconds or more from the secondary air duct, and the incinerator outlet temperature to an upper limit of the fireproof installation reaches about 900 °C to 1200 °C, said fireproof structure provided with an installation structure for refractory tiles to be installed around air supply ducts that supply combustion air, openings for the insertion of monitoring equipment, openings such as manholes for worker egress, and around clinker chill area, where the water pipes are bent into complex shapes, said installation structure to be provided on vertical walls and on ceilings, wherein the installing structure comprises:
  • this invention it is possible to easily install a fireproof structure to protect water pipes in the commonly used stoker type incinerators that operate at exceptionally high temperatures, whereby, instead of using an amorphous fireproof material such as the refractory castable that was used in the prior art in the areas where water pipes are bent into complex shapes around openings, refractory tiles having better longevity in these high temperature gas environments can be installed through the application of this invention.
  • Said refractory tiles 13 are manufactured in a factory, etc., off-site by molding the materials under pressure, sintering or other means of forming.
  • an indent 14 is formed in the tile on the side that faces water pipes 10.
  • the shape of support members 15 may be selected based upon manufacturing considerations and the place where they are to be used.
  • Figures 2(A) 3(A) and 4(A) show perspective views and Figures 2(B) 3(B) and 4(B) show sectional views of the first through third embodiments.
  • support member 15A comprises a T-shaped hook, the tip area 15Aa has a larger sectional shape than the base area 15Ab; with the vertical dimension of tip 15Aa being approximately the same length as the base 15Ab, which is attached to the foregoing water pipes 10.
  • the support member has a tip 15Aa that is stepped up from the base 15Ab dimension to improve the ability to be held in place by the foregoing mortar 12, to strongly attach refractory tiles 13 to the foregoing water pipes.
  • Figures 5 and 6 show the cross sectional views of fireproof structures for protecting water pipes employing a fourth and fifth embodiment of the support hardware (support members).
