Abstract (en)

The invention relates to a tunnel furnace for a baking process for ceramic materials, comprising a heating-, a firing- and a cooling zone. The firing zone comprises a stoking zone and a sintering zone and the stoking zone comprises burning zones equipped with gas burners, each burning zone having an initial and an end temperature set value.The tunnel furnace comprises a system steering - during the residence of the ceramic materials in a burning zone of the stoking zone - the temperature in the burning zone from the initial value till the end value according to a curve situated equal to or beneath the linear curve of the initial value till the end value of the burning zone. The invention also relates to a method for baking ceramic materials implementing the above steps. The tunnel furnace and method yield a substantive reduction in gas consumption and in fallout of disapproved baked products.
