Definitions

  • a kiln for the firing of tiles is substantially composed of a longitudinal chamber, of considerable size, inside of which carts are introduced containing the products to be fired.
  • the firing action of the material is achieved by means of a series of burners arranged inside the mouths present on the two side walls and on the flat arch of the firing chamber, which heat an air flow which flows through the entire length of the kiln.
  • the chamber is made with refractory walls, while panels of mineral wool, kaolin wool or other material suitable for the purpose, applied on the outside the walls and on the ceiling, thermally insulate the kiln.
  • Object of the present finding is to make a kiln for the firing of tiles in which the possible leakage of the air circulating inside the firing chamber, through the walls and the arch of the ceiling, is totally prevented.
  • Such objects are obtained with the making of a kiln for the firing of tiles which is characterised in that it has an air chamber made outside the walls and arch of the kiln, in which an air flow in overpressure condition runs, the value of such pressure being at least equal to the pressure value of the air which circulates inside the firing chamber.
  • the tile firing kiln according to the finding is substantially composed of a firing chamber 1, defined by the side walls 2, made with a refractory wall layer 2.1 and a thermal insulating material 2.2, and by a flat arch 3 which comprises the bearing beams 3.1 and the layer of insulating material 3.2.
  • the new characteristic of the finding consists in the definition of a chamber 10 placed outside the firing chamber 1, which extends for the entire surface of the arch 3 and for nearly the entire surface of the side walls 2, inside of which an air flow "K" runs in overpressure conditions, with a pressure value at least equal to the pressure of the air flow "F".
  • the air chamber 10 is composed of an upper portion 10.1, defined between the bearing beams 3.1 and the insulating layer 3.2 of the arch 3 and by two side portions 10.2, defined between the layer in insulating material 2.2 and a more external wall 11, all being contained within an insulating shell 12.
  • the secondary air flow "K” is inserted in the chamber 10, with preferably the same direction as that of the main air flow “F”, by means of the delivery tubes 13, equipped with nozzles 14; the air flow “K” is sucked, on the opposite side, by means of an extraction tube 15 equipped with a valve 16, where said valve serves to regulate the value of the pressure, so that the aforesaid flow "K” always operates in overpressure conditions with respect to the pressure value of the aforesaid main flow "F".
  • the side portions 10.2 of the air chamber 10 are, rather than empty, filled with a low density insulating material, so that one obtains both the passage of the air flow "K" and a simultaneous thermal insulation of the kiln.
