Batch homogenizing

Let’s take a look at homogenization in a conventional batch furnace. Here, the temperature cycle of a log largely depends on its position in the batch. It follows that 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. Now, our new generation of batch furnaces with reversing air function achieve 20 % faster heating. 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. What happens in the cooling chamber is that the log temperatures within a batch vary even more substantially. The different cooling rates result in inconsistent homogenization levels.
