Clay brick tunnel kiln

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 that the baking heat parameters are stable, so the firing quality is guaranteed.

Tunnel kiln system
The technology choose flat celling tunnel kiln. The tunnel kiln has complete system of
smoke discharging, cooling, heat releasing, pressure balancing under the kiln car, running and test system. Baking curve inside of the kiln will be more reasonable through the adjustment of those system.
There are entrance and exit doors at both ends of the tunnel kiln. At the entrance side, there is a preparatory room, and a cut-off door between the preparatory room and the kiln joint zone. Thus it effectively avoid entering the cold air and ensure the baking system of the kiln.

Tunnel kiln structure
Red brick is laid for the pre-heating zone and cooling zone where the temperature is below 200ºC. The rest part, baking zone and the innermost wall of insulating zone are adopt clay refractory brick. 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 Celsius) or rock wool felt will be used for stuffing and red bricks will be laid on the external wall.
Kiln roof structure: One kiln car space remained in low temperature zone on both side, which adopt cast-in concrete top slab. For other position, clay material plate, hanger plate through davit hang under H type steel beam by cast product. Both sides wall body support the main beam's weight. High aluminum cotton ,refractory fibro felt, rock wool felt, rock wool board are put on the refractory hander plate, which compose complex insulation layer. The crack between the top plate will be impacted by high aluminum fiber .High temperature binder is being filled up to the gap between the boards, and is being painted on the upside of the insulating layer, thus to ensure the material's insensitivity and structure's durability.
