BREVET KELLER HCW/ Method and device for firing ceramic blanks and oven

The method comprises guiding moldings in trains of oven running in parallel to each other and located along a longitudinal oven track (1) with a burning zone (7) in which heating of the moldings occurs, where the trains are arranged next to each other in opposing directions, and assembling the oven in a first direction (A) to move the moldings on a first side of the oven track concerning the burning zone and then in a second direction (B) to move the moldings on a second side of the oven track concerning the burning zone. The method comprises guiding moldings in trains of oven running in parallel to each other and located along a longitudinal oven track (1) with a burning zone (7) in which heating of the moldings occurs, where the trains are arranged next to each other in opposing directions, and assembling the oven in a first direction (A) to move the moldings on a first side of the oven track concerning the burning zone and then in a second direction (B) to move the moldings on a second side of the oven track concerning the burning zone. The moldings are moved in the burning zone through renouncement of a direct reversion via the burning zone, and are taken by open horizontal bars in the oven assembly. The moldings are directly heated in the burning zone by a heating element arranged in a longitudinal lane between the trains. The heating takes place via renouncement by leading cool air along the oven track via the burning zone. Air is transversely circulated over circulating zones located in both sides of the burning zone at the longitudinal direction of the oven track by a fan located in one of the trains or an intermediate ceiling of the oven. The rate of transversely circulated gas mass flow to the longitudinally circulated gas mass flow in the oven track is larger than 10. A variation of fuel curve is made by the variation of the rate of transversely circulated air. An independent claim is included for an oven for burning ceramic moldings such as bricks.
