Abstract

Intermittent tunnel kiln for firing ceramic parts in which gas is recycled as described in FR 7243925, has a large number of burners placed in the roof above the furnace and regularly distributed so that flames produced are arranged around the stacks of prods. to be fired. During cooling the burners are extinguised but the air continues to flow over the fired material as coolant. The coolant air is more uniformly distributed around the stacks, hence more uniform prods. are obtd.
