    2020-8-26 · The tunnel kiln has higher energy use. The energy efficiency of the VSBK kiln lies in its firing zone which does not come into contact with the ground insulated walls and counter-flow heat transfer (Maithel and Heierli 2008). In contrast the longwall surfaces of the tunnel kiln are exposed to open air leading to higher heat losses.
