Tunnel kilns are often used for applications in which temperature uniformity is important and when high levels of control are needed. A tunnel kiln has a 50% lower fuel consumption than a shuttle kiln and is extremely energy efficient. Tunnel kilns are frequently used in applications such as: Clay brick firing. Sanitaryware. Porcelain insulators.
