Problems solved by technology
[0012] Although it has been noted that controlling the temperature above and below the roller table plane of the kiln provides some positive effects in order to eliminate dimensional defects, no such positive effect has been mentioned in terms of flatness

Embodiment Construction
[0034] The figure shows the roller table plane of the kiln, indicated by 1, on which the tiles advance from the right to the left in the figure.
[0035] Above and below the roller table level are arranged the known axial burners 2, 20, 3 and 30, which are mainly used to heat the central zone of the kiln, and the known radial burners, which are mainly used to heat the area near the kiln wall. Burner 4,40.
[0036] The burners are arranged facing the side walls of the kiln, and the burners on one side wall are staggered relative to the burners on the opposite side wall.
[0037] Axial burners 2, 20 near the kiln entrance are used for pre-firing the tiles, while burners 3, 30, 4 and 40 are used for firing the tiles.
[0038] The rapid cooling of tiles starts from the downstream of the burners 4, 40, and the cold air (at room temperature) is sprayed through the nozzles, which face the plane of the roller table and are arranged in two transverse upper headers 5 and 6, and two tra...

A process for management and retro-active regulation of a tunnel kiln for firing ceramic tiles, comprises burners located above the roller plane and below the roller plane, nozzles dispensing forced cold air in a terminal part of the kiln, and means for detecting a temperature internally of the kiln, controlled by a processor, comprises the following operations: setting the processor for a desired temperature curve; memorizing in a first memory standard defects relating to shape and size of the tiles, memorizing in a second memory, for each of the standard defects, modifications for management of the kiln for in order to reduce the defects; performing at intervals on each tile of a same transversal alignment of tiles exiting from the kiln a control of a planarity and dimensions thereof in order to determine a type of defect detected by comparison with data contained in the first memory; and signalling the defect detected to the processor, which identifies the defect by comparison thereof with the data contained in the first memory and by modifying supply to the burners and to the cooling air nozzles on the basis indications of data contained in the second memory.
Description
technical field [0001] The invention relates to a tile kiln, in particular to product quality management of the tile kiln. Background technique [0002] The success of the tile firing phase in a kiln known as a tunnel kiln depends almost entirely on the strict adherence to the longitudinal temperature profile maintained inside the kiln over the entire transverse section of the kiln. [0003] In this context, the term "longitudinal profile" means the profile of the temperature in the direction of material advance, ie in a direction parallel to the axis of the kiln. [0004] The kiln mentioned here comprises roller table planes arranged in a tunnel structure with side walls for material transfer, and two series of burners arranged on the side walls towards the center of the kiln and along the entire length of the kiln, a series of burners in Arranged above the plane of the roller table, another series of burners are arranged below the plane of the roller table, wherein each s...
