(57) An intermittent combustion kiln, particularly for ceramic articles, comprising a
chamber (C) for thermal treatment of the articles, which is provided with a plurality
of first burners (2), with a circuit for aspirating and evacuating the exhaust gases
generated during the thermal treatment, and with at least one second regenerative-type
burner (3) with heat recovery of the exhaust gases of the chamber, which is adapted
to introduce in the chamber (C) hot combustion gases and to aspirate from the chamber
the exhaust gases, recovering their residual heat, the second regenerative-type burner
being provided with at least one regenerative exchanger which is connected to the
chamber, which is associable with at least one intake (7) for comburent air and with
at least one outlet (8) for the cold exhaust gases, and is adapted to be crossed alternately
by the exhaust gases of the chamber, accumulating their residual heat, and by the
incoming comburent air, transferring thereto the accumulated heat.
