(57) The present invention refers to a kiln for the firing of tiles, of the type substantially
composed of a longitudinal chamber of considerable size, inside of which the carts
are introduced containing the products to be fired, where the firing action of the
material is achieved by means of a series of burners, arranged inside mouths present
on the two side walls and on the flat arch of the firing chamber. These burners heat
an air flow, in slight overpressure, which runs for the entire length of the kiln.
Said kiln is characterised in that it has an air chamber (10) made outside the walls
and the arch of the kiln, in which an air flow (K) runs in overpressure condition,
the value of such pressure being equal to or greater than the pressure value of the
air flow (F) which circulates inside the firing chamber (1) (fig. 2).
