Abstract
In a tunnel kiln for the firing of ceramic products in a tunnel kiln having a preheating zone, a firing zone and a cooling zone, pulse-modulated gas flows from a ventilation unit in the cooling zone to a suction unit in the preheating zone. As a result, the convection heat transmission to the firing ware is increased, particularly in the preheating zone and the cooling zone, thus achieving a more even heat transmission over the entire length of the kiln.
