Clay brick tunnel kiln 

The tunnel kiln has complete system of smoke discharging, cooling, waste heat releasing, pressure balancing under the kiln car, running and detecting system. Baking curve inside of the kiln will be more reasonable, production system more coordination through the adjustment of those system.

At the entrance side, there is a preparatory room, and a cut-off door between the preparatory room and the kiln pre-heating zone. There are entrance and exit doors at both ends of the tunnel kiln. Thus it effectively avoid entering the cold air and ensure the baking system inside not be influenced by outside.

Clay brick tunnel kiln project 

Foundation: Tunnel kiln is with strip foundation. From bottom to up by order is plain concrete, reinforced concrete girder (railway girder)/ board (under kiln wall).

Wall: Red brick is laid for the pre-heating zone and cooling zone where the temperature is below 200℃. The rest is adopting combined wall. The fireclay bricks will be laid on the baking zone and inner wall of insulting zone. The clay insulting bricks will be used for laying the insulting area. Meanwhile, refractory fabric felt (for the relative part of temperature curve above 600℃) or rock wool felt will be used for stuffing and red bricks will be laid on the external wall.
