Tunnel kiln structure

Tunnel kiln structure:

1. Red brick is laid for the pre-heating zone and cooling zone where the temperature is below 200°C. The rest part, baking zone and the innermost wall of insulating zone are adopting 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.

2. Kiln roof structure:

a. One kiln car space remained in low temperature zone on both sides, 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.

b. High aluminum cotton ,refractory fibro felt, rock wool felt, rock wool board are put on the refractory hander plate, which compose complex insulation layer.

c. The crack between the top plates will be impacted by high aluminum fiber.

d. 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.

Tunnel kiln clay brick factory

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 avoids entering the cold air and ensures the baking system of the kiln.

Design and build clay brick tunnel kiln

The investment of kiln and dryer about 60~70% of whole project, we have professional team for kiln construction and supervision, most of the brick project facing problem from kiln and dryer. But we are professional in dryer and kiln.

Tunnel kiln is an advanced and automatic technology in brick making industry.

The features of tunnel kiln are as following:

1. Continuous kiln

A tunnel kiln is a type of continuous kiln that is typically open on both ends and heated centrally. Building materials, such as bricks, may be passed through the device in an uninterrupted fashion, allowing large volumes to be processed without shutting off the kiln between batches.

2. Fuel

A number of different methods can be used to heat tunnel kilns. Typical heat sources include coal,gas,and other fuel.
