Tunnel kiln outer specification	111×4.82×3.4 meters

Tunnel kiln adopt large section with inner width of 3.4 meter, it is designed as a flat ceiling structure with refractory bricks. Considering bricks can not have black center and patterns, the firing fuel source is major by inner-mixing-coal, outer-casting-coal as replenish, the heat should meet the firing technology requirement.

This kiln is suitable for firing products with 1600-2600KJ/Kg.

Tunnel kiln has smoke-releasing system, recycling system, waste-heat recovery system, cooling system and pressure balancing system.

This kiln has following features: large section, high yield, small section temperature difference, good heat preservation effect. Meanwhile, the kiln auto-control system is equipped to ensure the baking heat parameters are stable, so the firing quality is guaranteed.
