Optimizing the preheating zone in a tunnel kiln

In many tunnel kilns, in the higher temperature range (600 – 800 °C), high-velocity burners are installed for temperature homogenization. Energy input is not usually necessary for the process and, in isolated cases, it can even be detrimental. With the use of high-temperature circulating fans, a much more energy-efficient solution is achieved.
