Batch homogenizing

Let’s take a look at homogenization in a conventional batch furnace. Here, the temperature profile of a log largely depends on its position in the batch: Logs at the edges of a batch are more exposed to the convection from the heated gases. That means they reach the set temperature ahead of logs in the center. Our new generation of batch furnaces with reversing air function heat up 20 percent faster. Due to the reversing airflow, there is only a slight temperature deviation between the outer and inner logs. Crucial here is an intense air flow and ideal heat distribution for near-uniform log temperature throughout the stack. This is ensured by our improved air guide system which contributes to top results.
